OASIS Testbed and Experimental Platform

November 06, 2003

George PorterNTT 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?

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!)
