Introduction This draft provides a set of detailed tests of the SS7 MTP2-User Peer-to-Peer Adaptation Layer [M2PA09] based on the test specifications for SS7 MTP Level 2 [Q.781]. These tests are intended to validate the SS7 MTP2-User Peer-to-Peer Adaptation Layer (M2PA) protocol [M2PA09]. These tests attempt to completely validate the M2PA protocol without redundancy. Each test is described as simply as possible to check precisely the elementary function of the protocol. The tests are listed in no specific order[1]. 1.1. Scope Although the SS7 MTP Level 2 Test Specification [Q.781] is largely applicable to SS7 signalling links using the SS7 MTP2-User Peer-to- Peer Adaptation Layer [M2PA09], those test cases describe messages and some sequences that are not applicable to M2PA. This document describes a set of Validation and Compatibility tests that are consistent with the SS7 MTP Level 2 Test Specification [Q.781], but which are applicable to M2PA. The Test Environment used for M2PA testing described in this document is largely compatible with the SS7 Test Specifications [Q.780]. M2PA [M2PA09] provides that, unless modified by the M2PA specification [M2PA09], that the procedures of the applicable MTP Level 2 standard are to be used. This includes ITU [Q.703], ANSI [T1.111], ETSI [EN 300 008-1], TTC [JT-Q.703], and other narrow band specifications as well as broadband specifications for ITU [Q.2140], ANSI [T1.637], and others. This document describes testing of the procedures applicable to ITU signalling links [Q.781, Q.703] only. Some other testing methodologies applicable to ANSI [T1.111] or ETSI [ETS 300 336], although similar, are outside the scope of this document. 1.2. Terminology This document extends the terminology of M2PA [M2PA09] with the following terms: Compatibility Test (CPT) -- A test where multiple implementations are tested in interaction with each other to test for compatibility between implementations. B. Bidulock Version 0.4 Page 2 Internet Draft M2PA-TEST July 26, 2003 Implementation Under Test (IUT) -- An implementation being tested (the object of testing) as part of a Validation Test or a Compatibility Test within the Test Environment. Interoperability Test (IOT) -- A test where multiple implementations are tested in interaction with each other to test for interoperability between implementations. M2PA Monitor -- A device or function used to monitor, capture, record and analyze the exchange of M2PA messages across an IP network between implementations or protocol testers. This device or function may be integrated with a Protocol Tester. MTP Level 3 Simulator -- A device or function used to simulate the SS7 MTP Level 3 [Q.704] to SS7 MTP Level 2 [Q.703] implementation. This device or function may be integrated within the Test Environment. This device or function is normally required for SS7 MTP Level 2 Test Specification [Q.781] Validation as well as Compatibility tests. Protocol Tester (PT) -- A device or function used to generate normal or abnormal messages and test sequences for the purpose of Validation testing. Test Case -- A particular sequence of messages and patterns that make up a single Validation or Compatibility test. Test Environment -- The environment that contains testing device and functions necessary and sufficient for executing a Test Suite. Test Suite -- A collection of Test Cases meant to achieve a specific objective of Validation or Compatibility testing. Validation Test (VAT) -- A test where a single implementation is tested in interaction with a Protocol Tester to test for validation of the implementation to a technical specification. 1.3.

Conventions The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, NOT RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC 2119 [RFC 2119]. Notes for Section 1 [1] IMPLEMENTATION NOTE:-- An implementation of M2PA which conforms to these test specifications and a test program which executes the validation portion of these tests on that implementation are available from http://www.openss7.org/downloads.html 2. Test Environment The test environment for SS7 MTP Level 2 [Q.781] testing is described in the General Aspects of SS7 Testing [Q.780]. There are three types of testing that are accommodated as follows: Validation Testing -- consists of validating a single Implementation Under Test (IUT). This is performed by connecting the IUT to a Protocol Tester (PT) within the test environment. Validation testing is more extensive than compatibility testing. This is because it is possible, with the use of the PT, to generate abnormal messages and patterns that cannot normally be generated from an implementation. These tests validate the response of the IUT to abnormal (as well as normal) conditions. Compatibility Testing -- consists of testing the compatibility of one Implementation Under Test (IUT) with another. This is performed by connecting the IUT together within the test environment. Compatibility testing is less extensive than validation testing. This is because it is not normally possible to generate abnormal test patterns or generate negative test cases with an implementation that conforms to validation testing. However, compatibility tests are better at testing the interoperability of two implementations. Interoperability Testing -- consists of testing the interoperability of one Implementation Under Test (IUT) with another. This is performed by connecting the IUT together within the test environment. Interoperability testing is more extensive than compatibility testing and less extensive than validation testing. Where compatibility testing assumes that the IUT have passed validation testing, interoperability testing makes no such assumption. In addition, the test environment is expected to have more control over the IUT in interoperability testing than in compatibility testing. It may be possible to generate some message and command or response sequences that would not normally by possible with an B. Bidulock Version 0.4 Page 4 Internet Draft M2PA-TEST July 26, 2003 IUT during compatibility testing. The objectives of interoperability testing are often different than compatibility testing. The object of compatibility testing is to assure that an implementation that passes validation testing is, in other respects not tested by validation testing, compatible with other such implementations. The object of interoperability testing is to show that there exist implementations with which each of the IUT being tested can indeed function. Although they have different objectives, the test environment configuration for interoperability testing is the same as that for compatibility testing. This document uses the test environment described in the SS7 Test Specification [Q.780]. 2.1. Test Configurations This section details the Validation and Compatibility test configurations used for testing M2PA for SS7 MTP Level 2 [Q.781] conformance. 2.1.1. Validation Test Configuration ___________________________________________________________________ | | | TEST ENVIRONMENT | | MTP Level 3 | | Simulator | | : | | _________ ____:____ | | | | M2PA Link | | | | | PT |______________________________| IUT | | | | | | | | | | |_________| | SCTP |_________| | | | Association | | SP B ____|____ SP A | | | | | | | M2PA | | | | Monitor | | | |_________| | | | |___________________________________________________________________| Figure 2.1.1-1. Validation Test Configuration Figure 2.1.1-1 illustrates the Validation Test Configuration. The Validation Test environment contains the following essential components: B. Bidulock Version 0.4 Page 5 Internet Draft M2PA-TEST July 26, 2003 (1) Implementation Under Test (IUT) -- An implementation for validation testing acting as "SP A". (2) Protocol Tester (PT) -- A protocol testing device acting as "SP B". (3) MTP Level 3 Simulator -- A simulation device or function used to issue commands and collect response to and from the SS7 MTP2-User Peer-to-Peer Adaptation Layer [M2PA09] implementation at position "SP A". (4) M2PA Monitor -- A device or function used to monitor, capture, record and analyze the exchange of M2PA messages between the PT and IUT across the IP network in SCTP associations. (5) IP Network -- An intervening IP network used to form SCTP associations between PT and IUT and to exchange messages. (6) SCTP Associations -- An single SCTP connection formed between the PT and IUT for the exchange of M2PA messages. For this configuration, the interface between the Implementation Under Test (IUT) and the MTP Level 3 Simulator is that described in the SS7 Test Specification [Q.780]. This is the normal configuration for SS7 MTP Level 2 testing [Q.781] with the exception that an M2PA [M2PA09] signalling link has been interposed for an SS7 signalling link [Q.703]. All test cases in this document should be executed when performing Validation testing. 2.1.2. Compatibility Test Configuration B. Bidulock Version 0.4 Page 6 Internet Draft M2PA-TEST July 26, 2003 ___________________________________________________________________ | | | TEST ENVIRONMENT | | | | MTP Level 3 MTP Level 3 | | Simulator Simulator | | : : | | ____:____ ____:____ | | | | M2PA Link | | | | | IUT |______________________________| IUT | | | | | | | | | | |_________| | SCTP |_________| | | | Association | | SP B ____|____ SP A | | | | | | | M2PA | | | | Monitor | | | |_________| | | | |___________________________________________________________________| Figure 2.1.2-1. Compatibility Test Configuration Figure 2.1.2-1 illustrates the Compatibility Test Configuration. The Compatibility Test environment contains the following essential components: (1) Implementation Under Test (IUT) -- An implementation for compatibility testing acting as "SP A". (2) Implementation Under Test (IUT) -- An implementation for compatibility testing acting as "SP B". (3) MTP Level 3 Simulator -- A simulation device or function used to issue commands and collect responses to and from the SS7 MTP2-User Peer-to-Peer Adaptation Layer [M2PA09] implementation at position "SP A". (4) MTP Level 3 Simulator -- A simulation device or function used to issue commands and collect responses to and from the SS7 MTP2-User Peer-to-Peer Adaptation Layer [M2PA09] implementation at position "SP B". (5) M2PA Monitor -- A device or function used to monitor, capture, record and analyze the exchange of M2PA messages between the IUT across the IP network in SCTP associations. (6) IP Network -- An intervening IP network used to form SCTP associations between IUT and to exchange messages. (7) SCTP Associations -- A single SCTP connection formed between IUT for the exchange of M2PA messages. B. Bidulock Version 0.4 Page 7 Internet Draft M2PA-TEST July 26, 2003 For this configuration, the interface between each Implementation Under Test (IUT) and the MTP Level 3 Simulator is that described in the SS7 Test Specifications [Q.780]. Tihs is the normal configuration to SS7 MTP Level 2 testing [Q.781] with the exception that an M2PA [M2PA09] signalling link has been interposed for an SS7 signalling link [Q.703]. Only select test case apply to Compatibility testing in accordance with the SS7 MTP Level 2 Test Specification [Q.781]. 2.1.3. Interoperability Test Configuration The interoperability test configuration closely resembles that for compatibility testing as illustrated in Figure 2.1.2-1, above, with the exception that the MTP Level 3 Simulator typically has more capabilities for controlling the implementation during testing. For example, the MTP Level 3 Simulator can in some instances be capable of closely controlling the sequence of messages generated by the implementation and may even be able to inject or withhold messages during testing. 2.2. Testing Methodology The normal methodology for testing SS7 MTP Level 2 [Q.781] is to perform Validation testing on an IUT before performing Compatibility testing. The tests presented in this document test functionality the the M2PA MTP Level 2 state machines; however, they do not adequately test the M2PA L2 to L3 interface. To complete Validation and Compatibility testing of M2PA, the Validation and Compatibility tests present in the SS7 MTP Level 3 Test Specification [Q.782] SHOULD be performed with M2PA links in the test environment to assure that the M2PA IUT has properly implemented the L2 to L3 interface. 2.3. Recommended IUT Settings The following settings are recommended[1] for use with both Validation and Compatibility testing, in the absence of other recommended values to be adopted by the PT and IUT. 2.3.1. Timer Values It is recommended[1] that the timer values listed in Table 2.3.1-1 be configured at the IUT for the purposes of performing both validation and compatibility tests. B. Bidulock Version 0.4 Page 8 Internet Draft M2PA-TEST July 26, 2003 Table 2.3.1-1. Recommended[1] IUT Timer Values Timer Value Units Notes ------------------------------------------- T1 45 seconds T2 5 seconds T2l 20 seconds (not applicable) T2h 100 seconds (not applicable) T3 1 seconds T4n 8 seconds T4e 0.5 seconds T5 0.1 seconds (not applicable) T6 4 seconds T7 1 seconds T8 0.1 seconds (not applicable) ------------------------------------------- 2.3.2. Buffer Threshold Values It is recommended that the buffer threshold values listed in Table 2.3.2-1 be configured at the IUT for the purpose of performing both validation and compatibility tests. Table 2.3.2-1. Recommended IUT Buffer Threshold Values Threshold Value Units Notes ------------------------------------------------ N1 -- Octets (not applicable) N2 127 Messages 2.3.3. MSU Length It is illustrated that all normal User Data messages which are sent have a payload length of 35 bytes. This, however, is not essential to the correct performance of the tests and is an arbitrary choice. Use of different valid MSU lengths should not have an affect on the results. 2.3.4. Labeling of Messages and Primitives The messages and primitives (requests and indications between M2PA and MTP3) in the test cases that follow are labeled as listed in Table 2.3.4-1. All tests are labeled with "VAT:", "CPT:" or "IOT", indicating that the test is applicable to Validation, Compatibility or Interoperability forms of testing. B.

Bidulock Version 0.4 Page 10 Internet Draft M2PA-TEST July 26, 2003 Notes for Section 2 [1] IMPLEMENTATION NOTE:-- The values are recommended to facilitate testing only, and do no represent a recommendation for operational networks. Operational values must be determined considering the needs of the operational network in which M2PA must function. 3. Tests The M2PA Validation ("VAT") and Compatibility ("CPT") tests cases are detailed in the sections that follow. All tests cases that are applicable to M2PA are applicable to Validation testing. Selected test cases (marked as "CPT" in Table 3-1) are applicable to M2PA Compatibility testing. Interoperability testing at an IETF interoperability event may include some additional Validation tests in Interoperability testing, depending on the capabilities of the MTP Level 3 Simulator. These additional tests have been marked "IOT" in Table 3-1. Table 3-1.

Initialization (Power-up) These tests check that the IUT enters the correct state upon establishment of the SCTP association. Establishing the association at both peers is the equivalent to the Q.703 "Power On". The correct behavior is for both M2PA peers to send a status "Out of Service" and enter the "Out of Service" state. These test are useful both for Validation and Compatibility testing. 3.1.1.1.

Security Considerations Although this document does not introduce new security considerations for M2PA, mention of the role of M2PA security measure during tested is in order. When the Validation, Compatibility and Interoperability tests in this document are being performed, the test environment and Implementations Under Test (IUT) MUST use the security measures required in the Security section of the M2PA specification [M2PA09] while the tests are being performed. Test results without the required security measures in place during testing will be of little value for validating the behavior of an implementation for later operation. B. Bidulock Version 0.4 Page 123 Internet Draft M2PA-TEST July 26, 2003 IANA Considerations There are no IANA considerations for this draft. 0. Change History This section provides historical information on the changes made to this draft. This section will be removed from the document when the document is finalized. 0.4. Changes from Version 0.3 to Version 0.4 (1) The test specification has been updated to M2PA Draft Revision 9 [M2PA09]. (2) Split references into Normative and Informative. (3) Updated acknowledgments to include those making comments on the draft. (4) Added section describing labeling of messages and primitives in the diagrams. (5) Expanded test environment description. Tests have been identified for compatibility and interoperability testing. (6) Added a test list showing which tests are applicable to Validation, Compatibility and Interoperability testing. (7) Added a Security section describing that M2PA security measures must be in place during testing. (8) M2PA Draft Revision 9 [M2PA09] uses normal initial sequence numbers. Sequence numbers on all tests have been updated to match. (9) M2PA Draft Revision 9 [M2PA09] makes proving configurable. Test cases have been added to 3.1.5, 3.1.6, 3.1.8, 3.1.9, 3.1.10, 3.1.11, 3.1.12, 3.1.13, 3.1.15, 3.1.16 and 3.1.27 to test also the situation where the link is not configured for proving. (10) M2PA Draft Revision 9 [M2PA09] uses a flexible T7 timer that times the age of the oldest unacknowledged data message in the retransmission buffer. This is slightly different that MTP2 [Q.703, T1.111] behavior. A test case was added to 3.8.12 (Excessive delay of acknowledgment) to test this variation from MTP2. (11) M2PA Draft Revision 9 [M2PA09] has some problems with T6 and T7 timer handling. It is anticipated that changes will be made to the T6 and T7 timer handling. Additions to test case 3.10.2 have been made in anticipation of these changes. B. Bidulock Version 0.4 Page 124 Internet Draft M2PA-TEST July 26, 2003 (12) PROCESSOR-OUTAGE-ENDED renamed to PROCESSOR-RECOVERED. (13) M2PA Draft Revision 9 [M2PA09] has some problems with processor outage handing. It is anticipated that changes will be made to the processor outage handling on both sides. Addition or changes to test cases 3.4.1 and 3.8.9 have been made in anticipation of these changes. (14) Link Status "Out of Service," "Alignment," "Ready," and "Processor Outage" messages can be repeated until the condition that caused them to be sent has cleared. Comments have been added to test cases 3.1.1, 3.1.2, 3.1.4, 3.1.16, 3.8.13 and 3.10.1 to accommodate for this. (15) Link Status "Proving Normal" and "Proving Emergency" messages are repeated at the proving interval. Notes have been added to test cases performing proving to indicate that these messages may be repeated. (16) Added Link Status "Busy Ended" and "Processor Recovered" as well as M2PA messages with invalid message class and message type to test cases 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5, 3.2.6, 3.2.7 and 3.2.8 to fully test unexpected message sequences. (17) Added new test case 3.8.14 to test the situation where the IUT receives an out of order forward sequence number. For the most part, however, there have been few changes to the actual test cases. 0.3. Changes from Version 0.2 to Version 0.3 (1) The test specification has been updated to M2PA Draft Revision 7 [M2PA07], with anticipated changes for M2PA Draft Revision 8 [M2PA08]. 0.2. Changes from Version 0.1 to Version 0.2 (1) The test specification has been updated to M2PA Draft Revision 6 [M2PA06], with anticipated changes for M2PA Draft Revision 7 [M2PA07]. (2) M2PA Draft Revision 6 [M2PA06] provides for acknowledgment of DATA messages using a special DATA message which contains no data payload. This message has been labeled "DATA-ACK" in the diagrams. This has resulted in changes to test cases 1.6, 2.1, 2.2, 2.3, 2.4, 3.2, 3.4, 3.6, 3.8, 4.1, 8.1, 8.3, 8.4, 8.5, 8.9, 8.10, 8.11, 10.2 (3) Although M2PA Draft Revision 6 [M2PA06] specifies that the DATA-ACK message should have its Forward Sequence Number (FSN) incremented as with any other normal DATA message, this causes B. Bidulock Version 0.4 Page 125 Internet Draft M2PA-TEST July 26, 2003 problems in that the DATA-ACK MUST then be acknowledged. This test specification anticipates M2PA Draft Revision 7 by not incrementing FSN for DATA-ACK messages. (4) M2PA Draft Revision 6 [M2PA06] provides FSN and BSN sequence numbers in STATUS messages as well as DATA messages. It has been proposed that STATUS messages not contain FSN and BSN because they should essentially be ignored because of mis- ordering possibilities. Therefore, FSN and BSN of STATUS messages are ignored in this version of the test specification in anticipation of M2PA Draft Revision 7. 0.1. Changes from Version 0.0 to Version 0.1 (1) The test specification has been updated to M2PA Draft Revision 4 [M2PA04], with anticipated changes for M2PA Draft Revision 5 [M2PA05]. (2) M2PA Draft Revision 4 [M2PA04] no longer contains a special proving message. Status PROVING-NORMAL or PROVING-EMERGENCY messages are padded and sent repeatedly to accomplish proving during the proving period. The occurrence of PROVING messages has been removed from the test cases to update this draft to match the M2PA draft revision 4 [M2PA04]. (3) M2PA Draft Revision 4 [M2PA04] contains both forward and backward sequence numbers (FSN, BSN). The test cases were updated to include the sequence numbers (where other than zero) and test cases were added for abnormal backward sequence numbers. (4) M2PA Draft Revision 4 [M2PA04] has no formal method for acknowledging the receipt of a DATA message when there are no other messages to send (DATA or STATUS). The Status of "In Service", for which no other use has been specified in the current draft [M2PA04], is used as such an explicit acknowledgment. Another possibility would have been to send a DATA message with no data in it. The old "ACK" message is now labeled "IN-SERVICE". (5) The status message previously labeled "IN-SERVICE" has been relabeled "READY" to better reflect the name of that status message in the draft and to not conflict with the new [M2PA04] "IN-SERVICE" status message.
