1. Introduction
In Japan, a high-speed internet of fixed network is used to a lot of
people. The use of smartphones and tablet devices increases, the
mobile network is also faster. Users know the maximum bandwidth of
last mile for fixed network (100Mbps to 2Gbps in FTTH) and mobile
network (37.5Mbps to 112.5Mbps in LTE). However, users do not know
the performance of the actual network. In order to know them, it is
necessary to measure the actual performance of the network. In
addition, users need to know the performance of other network
providers as information for selecting the network.
Measurement providers measure a network performance from users to
multiple content providers using a dedicated hardware or software.
They will show the result with measurement methods and measurement
parameters.
This document introduces a new use cases of measurement provider for
LMAP described in [LMAP-USE-CASES].
2. Use Case for Measurement Provider
Measurement providers measure a network performance from users to
multiple content providers to show a performance of the actual
network. Users need to know a performance that are using their own.
In addition, they need to know a performance of other ISP of same
location as information for selecting the network. Measurement
providers will show the measurement result with measurement methods
and measurement parameters.
The following is a case that is currently implemented.
2.1. Measurements for Fixed Networks with dedicated hardware
We have measured a network using dedicated hardware fixed network.
We put a dedicated hardware to multiple locations in Japan.
Measurement provider distributes dozens of dedicated hardwares, Linux
box with ARM 600MHz ARM Processor and 512M memories.

Internet-Draft LMAP Use Case for Measurement Provider July 2013
With major fixed broadband access service in Japan, we can select ISP
services using one FTTH access line. Therefore we can measure many
ISPs with one FTTH spot. In our trial, we measured 117 ISP-location
sets by 9 Linux boxes and 13 ISP accounts.
The architecture of measurement system is composed of Linux box MAs
and the control Linux server. They act as follows: Before
measurement, we made measurement plan file and set it on contorl
server beforehand.
1. Distributing MAs to some locations.
2. MAs are powered on and connected to FTTH access line.
3. MAs set up PPPoE connection to ISP service.
4. After getting an IP address, MAs set up VPN connection to the
control server.
5. MAs fetch measurement plan file from control server, interpret
and execute it.
6. MAs put measurement results to control the server.
7. MAs check plan file again, back to step 5.
The plan file is described by the shell script. It can set crontab
and can execute any active measurement commands. We also send
measurement results from plan file. MAs can act autonomously and can
perform without control server.
In our measurement, measuring metrics are RTT, traceroute, HTTP GET
(through-put) from/to OTT services.
There are some problems of measurement architecture from this
experiment.
o Scalability is not enough in openvpn tunnel, upload results and
checking plan file.
o It is necessary to consider security risks for plan file in
control server.

2.2. Measurements for Fixed Networks with software
The measurement is designed to ask users visit the measurement site.
When the user visits the measurement site using a browser,
measurement is performed. Because it is measured using the software,
we can perform the measurement from the many MAs.
Since the measurement was performed when the end users accessed to
the designated measurement site, each individual result was readily
available to each participating user himself.
There are two performance measurements. One is performed by an
academic researcher and another is performed by a company.
In academic research, the overall summary of all the participants was
presented at several conferences that the author attended, and is
also available through one of the author's webpage [JITSUZUMI-WEB]
and a slideshare site [JITSUZUMI-SLIDESHARE]. These measurements
were part of academic researches, and therefore all of the costs were
covered by the research grants from the government.
The measurement company shows individual results and a summary of the
measurements to participating users, free of charge. The cost of the
measurement is covered by offering detailed results, after proper
anonymization, to interested companies for fee.
2.3. Measurements for Mobile Networks with smartphone
Measurement provider distributes a measurement applications to users
for smart phones. By using this application, the user performs the
measurement to the servers from a smartphone.
There are two type of measurements.
1. Run a measurement when users push a measurement button. We have
been measured to the servers from 500,000 MAs.
2. Run a measurement periodically. Measurement application is
executed periodically in the background. We have been measured
to the servers from 2,000 MAs.
3. IANA Considerations
There are no IANA considerations in this memo.
4. Security Considerations
TBD
