OASIS Testbed and Experimental Platform
November 06, 2003George 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!)
