The VINT Project

TASK PARTITION

• Sandeep Bajaj and Lee Breslau (Xerox PARC)
• Adding support for admission control for controlled load services.
• Kevin Fall
• network emulation
• flow monitoring (for Router Mechanisms paper w/Sally)
• continue debugging of tcp-full as needed
• Sally Floyd and Kevin Fall
• RED (works, except q-size traces), CBQ ported to ns-2.
• Router Mechanisms to Support End-to-End Congestion Control, Technical report, February 1997. Abstract. Simulation scripts in progress.
• Deborah Estrin (USC/ISI)
• Mark Handley
• test suite working under version 2
• stab at debugging support
• John Heidemann (ISI)
  • examining ns performance/scaling (with Polly), looking at empirically determining router buffering, shepherding the VINT overview paper
• Tom Henderson
• satellite networks (MAC, transport issues, multicast)
• Ahmed Helmy
• multicast routing code and test suites
• cut at overview documentation w/ Kevin and Kannan
• Polly Huang
• centralized multicast
• interface to switch between session level and detailed simulators
• Satish Kumar
• Wireless sensor network simulations
• Steven McCanne
• v2 architecture
• first cut at external emulation rig
• rlm
• Reza Rejaie
• congestion control for real time data streams
• Nader Salehi
• Multicast congestion control, Reliable multicast, Bidirectional PIM.
• 32-Bit addressing.
• Puneet Sharma
• Scalable Session Messages for SRM
• some nam demos from an old srm implementation (with old packet formats)
• Haobo Yu
• Application-level simulation support, e.g., web caching.
• Kannan Varadhan (USC/ISI)
• unicast, dynamic routing
• desigining various tests to stress dynamic routing
• cut at overview documentation w/ Kevin
  TODO next: Document the Simulator, Node, Link, RouteLogic/Routing, Dynamics objects.
• ISMA demos are now available. The tar file includes a copy of the slides, as well a standalone working collection of demos, including the driver, run-demos.
• New versions of test suites. Need to redo the ktest-all, to be more efficient about selecting topologies, and to skip some tests, or not compare others based on tags.
• First cut of SRM done and checked in. Does the Deterministic, Probabilistic, fixed and Adaptive timers algorithms from the sigcomm 95 paper by Floyd et.al.
  Next up, Local Group Mechanisms...
• Padma Haldar
• Hierarchical routing.
• Topology and scenario generator for ns.
• Members of the Daedalus Group, UC Berkeley (Hari Balakrishnan, Giao Nguyen, Venkat Padmanabhan)
  
  • Modeling LANs and wireless networks, including:
    • Link-layer protocols: simple stop-and-wait protocol, TCP-aware snoop protocol, etc.
    • MAC protocols: CSMA/CA, CSMA/CD, 802.11, RTS/CTS-based protocol for multihop wireless based on Metricom's Ricochet.
    • Scheduling algorithms at LAN interface queues.
    • A shared channel with wireless error models.
  • TCP and router enhancements for studying and improving TCP performance over various asymmetric networks. Simple nam modifications for visualizing transfers over asymmetric networks.
  • Support for tracing TCP state variables.
• Hyunah Park
• Developing nam features
• Please add yourself (and include where you are).
