Rice University: Network Systems Architecture Class

Owner

Scott Rixner, Jeff Shafer

Description

The NetFPGA system was used at Rice University to teach a class on network systems architecture. It was modeled on Stanford's CS344 course where students construct an IP Router. We learned a lot about NetFPGA that is applicable towards both research and education applications, and wanted to share some of our thoughts with the user group.

Router buffer sizing (University of Toronto)

Description

In this work, we set up a test-bed of several Dell Power Edge 2950 servers each equipped with NetFPGA boards to perform experimental studies on router buffer sizing. With NetFPGA as the router, one can control the buffer sizes with high precision, based on the number of packets or bytes, and without the worry of hidden buffers in the system. We have also added a module to the NetFPGA-based router to collect accurate buffer occupancy time-series, and to accurately measure the bottleneck link's utilization and loss rate. We have also written scripts to automatically set up a test-bed of NetFPGA routers. The scripts discover the network topology, set up the ARP tables, configure IP addresses, and routing in the test-bed.

Click Any-to-Any test (ICSI)

Description

Any to Any test using click, http://www.icsi.berkeley.edu/~nweaver/ntest.tar

Owner

Nicholas Weaver, ICSI

Summary

This test invokes Click to run an "any to any" send test. It first sends a total of 16 ethernet Broadcast packets, with the SRC mac as CA:FE:BA:BE:00:p# and the dest MAC as FF:FF:FF:FF:FF:FF, ethertype 0x890F (an unassigned ethertype). It will then repeat forever, sending a packet from a pseudo-random SRC to a different pseduo-random DST, ethertype 0x890F.

PTP: Precision Time Protocol

This project implements PTP standard by using NetFPGA platform. PTP is a simplified version of "IEEE 1588 standard which is a protocol designed for synchronizing real time clocks in the node of a distributed system that communicates using a network" [1]. In this project required changes has been made in NetFPGA's reference_router design in order to support PTP. In this document first we explain briefly how PTP works. In the following the software and hardware parts of the design are explained. For those people which are interested in using PTP router for clock synchronization, a chapter is designated to explain how to setup the nodes and configure the system. Finally some intermediate results are presented which are achieved using the PTP router for synchronization.

People involved in this project are Sara Bolouki, Peter Pawlowski, Jad Naous.

Packet generator

Description

A simple "packet generator/capture" system that uses the NetFPGA to transmit sequences of packets. In this design, the packet sequence is loaded into SRAM and the NetFPGA replays the sequence from SRAM. Sequences can include delays between packets or can simply be replayed at line rate. The design supports separate sequences on each of the 4 ports. The design also supports iterating over the sequences any number of times.

Ericsson Research Nomadic Lab & HIIT: Publish/Subscribe

Description

The "future internet" projects PSIRP and ICT SHOK are evaluating new approaches to internetworking. One of the most promising new ideas is to apply the publish/subscribe paradigm in the internetworking layer, instead of the currently dominant send/receive paradigm used in most networking protocols today.

Publish-subscribe networks have traditionally been overlays on top of IP. However, now that we are studying what would be the gains of applying this paradigm directly on top of link layer or even bare hardware, we need to evaluate the performance of this architecture against the dominant IP architecture. NetFPGA seems like a good tool to do that, as there is the reference IP router implementation, to which we can compare our own pub/sub-based information router.
