OASIS Testbed and Experimental Platform

• NTT Multimedia Communications Laboratories

Overview

• Trend new applications are moving into the edges
  of the network
• The core remains unchanged
• Easy to add box to the network to obtain new
  services
• This is leading to trouble
• Myriad configurations, vendors, platforms,
  programming environments
• Combinations of these functionalities hard to
  understand, manage, and control
• We propose Programmable Network Elements (PNEs)
• General service platform for the edge
• Simple, composable, stateful, and customizable
  packet filters create packet processing paths in
  the router
• Our specification language makes packet
  processing as well as stream processing a
  first-class citizen
• How to deploy? What infrastructure can be
  utilized to evaluate our design?

• Update VLANs on the Passport
• Update interfaces on the linux machines
• Update routing tables on the linux machines
• Update packeteer/alteon184

General Management

• Ensure that the ISDs are up
• Alarms when the machines go down, run out of disk
  space, etc (be careful what you ask for!)
• Current testbed status via webpage
• (Partially Completed)
