I2RS working group S. Hares Internet-Draft Q. Wu Intended status: Standards Track Huawei Expires: April 21, 2016 J. Tantsura R. White Ericsson October 19, 2015 An Information Model for Basic Network Policy and Filter Rules draft-hares-i2rs-bnp-eca-data-model-02.txt Abstract This document contains the Basic Network Policy and Filters (BNP IM) Data Model which provides a policy model that support an ordered list of match-condition-action (aka event-condition-action (ECA)) for multiple layers (interface, L1-L4, application) and other factors (size of packet, time of day). The actions allow for setting actions (QOS and other), decapsulation, encapsulation, plus forwarding actions. The policy model can be used with the I2RS filter-based RIB.

Introduction This generic network policy provide a model to support an ordered list of routing policy or an ordered list of filter rule. ne examples of the ordered-based filters is the I2RS Filter-based RIBs, and another is flow-specification filters. The first section of this draft contains an overview of the policy structure. The second provides a high-level yang module. The third contains the yang module. 1.1. Definitions and Acronyms INSTANCE: Routing Code often has the ability to spin up multiple copies of itself into virtual machines. Each Routing code instance or each protocol instance is denoted as Foo_INSTANCE in the text below.

Antecedents this Policy in IETF Antecedents to this generic policy are the generic policy work done in PCIM WG. The PCIM work contains a Policy Core Information Model (PCIM) [RFC3060], Policy Core Informational Model Extensions [RFC3460] and the Quality of Service (QoS) Policy Information Model (QPIM) ([RFC3644]) From PCIM comes the concept that policy rules which are combined into policy groups. PCIM also refined a concept of policy sets that allowed the nesting and aggregation of policy groups. This generic model did not utilize the concept of sets of groups, but could be expanded to include sets of groups in the future. 2. Generic Route Filters/Policy Overview This generic policy model represents filter or routing policies as rules and groups of rules. The basic concept are: Rule Group A rule group is is an ordered set of rules . Rule A Rule is represented by the semantics "If Condition then Action". A Rule may have a priority assigned to it.

BNP Rule Groups Rule groups have the following elements: o name that identifies the grouping of policy rules o role - that is a combination of target resource (E.g. IPv4 FB-FIB filters) and a scope (read, read-write, write-only). o list of rules The rule has the following elements: name, order, status, priority, reference cnt, and match-action as shown as shown in figure 2. The order indicates the order of the rule within the list. The status of the rule is (active, inactive). The priority is the priority within a specific order of policy/filter rules. A reference count (refcnt) indicates the number of entities (E.g. network modules) using this policy. The generic rule match-action conditions have match operator, a match variable and a match value. The rule actions have an action operator, action variable, and an action value. Hares, et al. Expires April 21, 2016 [Page 4] Internet-Draft BNP Generic Policy/Filter IM October 2015 The generic rules can be included with other types of rules as figure 2 shows.

The general actions may be generic actions that are specific to a particular layer (L1, L2, L3, service layer) or time of day or packet size. The qos actions can be setting fields in the packet at any layer (L1-L4, service) or encapsulating or decapsulating the packet at a layer. The fwd- actions are forwarding functions that forward on an interface or to a next-hop. The rule status is the operational status per rule. Hares, et al.

Security Considerations These generic filters are used in the I2RS FB-RIBs to filter packets in a traffic stream, act to modify packets, and forward data packets. These I2RS filters operate dynamically at same level as currently deployed configured filter-based RIBs to filter, change, and forward traffic. The dynamic nature of this protocol requires that I2RS Filters track the installer of group information and rules. This section will be augmented after a discussion with security experts. 8.
