Presentation Transcript

  1. OASIS Testbed and Experimental Platform November 06, 2003 George Porter NTT Multimedia Communications Laboratories

  2. 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) • Generalservice 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?

  9. Virtual->Physical Mapping 15ms Delay 8% drop rate PNE 20ms Delay 5% drop rate

  10. Virtual->Physical Mapping 15ms Delay 8% drop rate PNE 20ms Delay 5% drop rate • Update VLANs on the Passport • Update interfaces on the linux machines • Update routing tables on the linux machines • Update packeteer/alteon184

  11. 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)
