Impact of TCP-Like Congestion Control on the Throughput of Multicast Groups

whitepaper This paper studies the impact of randomness (i.e.variation of queuing delay due to cross traffic) on the performance of a (one-to-many) multicast session in the presence of a "TCP-like" congestion control mechanism.

The Role of Buffer Management in Controlling the Effects of Congestion over 10 GbE Links

whitepaper DBP-sized buffers, together with RED congestion avoidance, can be used to optimize the utilization of congested links by TCP applications. This white paper describes the rationale for providing switch/routers with port buffers that are scaled to...

Estimating the Ad Hoc Horizon for TCP Over IEEE 802.11 Networks

whitepaper The paper suggests that only combined efforts on MAC, routing and TCP level will permit to extend this limit, which can serve as a benchmark for future proposals. This horizon is defined in terms of number of nodes and number of hops beyond which...

On the Modeling of TCP Latency and Throughput

whitepaper Combining these short and steady state models, the paper proposes an extensive stochastic model which can accurately predict the throughput and latency of the TCP connections as functions of loss rate, round-trip time (RTT), and file size.
