Towards a More Stable Network Infrastructure

Speaker: Radhika Mittal, University of California, Berkeley

Location: 60 Fifth Avenue 150

Date: February 26, 2018, 2 p.m.

Host: Jinyang Li

Synopsis:

There have been many recent proposals to change the network infrastructure in order to meet different performance objectives. These changes are often difficult to deploy, either requiring specialized network switching hardware or greatly complicating network management. Rather than continuing to add new features to the network in an ad-hoc manner, my work advocates a principled approach for meeting different performance objectives, that leads to a more stable network infrastructure. This approach is based on the following two questions: First, can we avoid making changes to the network infrastructure by looking for solutions that only change the end-points? Second, when infrastructure changes are needed, can we make them universal in nature? In this talk, I will primarily focus on the second question, where I explore whether we can have a universal packet scheduling algorithm, that can mimic all other scheduling algorithms. Towards the end, I will briefly present three examples in the context of wide-area and datacenter congestion control, where I tackle the first question of avoiding changes to the network infrastructure.

Speaker Bio:
