Congestion Control for NDN-RTC

Participants

• Klaus Schneider (University of Arizona)
• Hila Abraham (Washington University of St. Loius)
• Giulio Grassi (University of Pierre et Marie Curie)
• Chngyu Fan (Colorado State University)
• Peter Gusev (REMAP)

Motivation

Currently, NDN still lacks an effective congestion control mechanism. Moreover, NDN-RTC has known performance problems which may be partly related to congestion. Thus, we try to implement a simple congestion control mechanism in NDN-RTC and show the benefits in a performance evaluation.

Tasks

• Run multi-consumer tests using ndncon on local testbed:
• Start small: 1 consumer, 2 consumers, 3 consumers
• Goal:Break ndncon/NFD - obtain unsatisfactory (from QoE standpoint) performance
• Evaluating the performance in multiple scenarios
• Figure out root causes of poor perfomance
• Parse crititcal NDN-RTC metrics:
• RTT', RTT estimation, Pipeline size, Buffer indicators
• Analyze gathered metrics and identify "bad scenarios"
• Come up with solution and propose changes to NDN-RTC and/or NFD
• Present results
