This report describes how to use the provided script for NFD performance benchmark
|
|
on ONL (https://onl.wustl.edu/).
|
|
|
|
Assumptions
|
|
===========
|
|
|
|
This report assumes that users have an ONL account. If you don't have an account
|
|
yet, please refer to the ONL official website to apply.
|
|
|
|
|
|
Experiment Steps
|
|
================
|
|
|
|
1. Login on the onlusr machine:
|
|
ssh -L 7070:onlsrv:7070 <your_account>@onl.arl.wustl.edu
|
|
|
|
2. Run RLI
|
|
Open the topology file, and make reservation; if it is not successful,
|
|
change the reservation time, and try again
|
|
|
|
When your reservation is ready, commit.
|
|
|
|
3. Experiment Environment setup
|
|
ONL does not allow us to install programs, this section describes the process
|
|
to compile NFD code on your experiment nodes.
|
|
|
|
(1) git clone the latest ndn-cxx code and NFD code to your home directory.
|
|
|
|
git clone http://gerrit.named-data.net/NFD
|
|
git clone http://gerrit.named-data.net/ndn-cxx
|
|
|
|
(2) In RLI, you can see the nodes name. Just choose one, and ssh to it.
|
|
|
|
(3) Compile and install ndn-cxx in your home directory. And then the NFD code.
|
|
|
|
For NFD, you need to compile using debug mode. You may need to specify
|
|
the PKG_CONFIG_PATH of the ndn-cxx library, and CXXFLAGS to make it work.
|
|
|
|
(4) script modification
|
|
|
|
clone scripts:
|
|
git clone https://github.com/WU-ARL/NFD_Performance_Testing_on_ONL.git
|
|
|
|
Note that John's script is to do the NFD performance testing, not for
|
|
latency. Besides, it is for the older NFD version, we have to make some
|
|
modifications:
|
|
|
|
(A) in config_server.sh and config_client.sh, change the 4 to 258 in
|
|
"nfdc add-nexthop -c 1 / 4"; in configRtr.sh, change the change the
|
|
START_FACE_ID to 258 (4 is the start face id for older NFD version)
|
|
|
|
(B) modify the "start_nfd.sh", let it run the latest NFD, not the one
|
|
installed on ONL, which is v0.1.0
|
|
|
|
ex: /path/to/your/nfd --config nfd.conf >& /tmp/nfd.log &
|
|
|
|
(C) modify "server/config_server.sh", let it run the latest nfdc
|
|
|
|
(D) same reason as (C), modify "client/config_client.sh"
|
|
|
|
|
|
NFD Throughput Benchmark
|
|
========================
|
|
|
|
Do test as the README in John's scripts describes.
|
|
|
|
|
|
|
|
NFD Forwarding Latency
|
|
======================
|
|
|
|
1. ssh to the NFD router, use tcpdump to capture traffic:
|
|
sudo tcpdump -i data0 'port 6363' -c 1000 -vv -w /tmp/mkall-16-udp4-10-1-5.port6363.pcap
|
|
|
|
2. run the script
