The ERICA switch algorithm has been discussed extensively in TM group in the past. However, over the last two years, the algorithm has been substantially modiied. This contribution describes the current version of ERICA switch algorithm in complete detail. The algorithm achieves both eeciency and fairness, and exhibits a fast transient response. The(More)
The Available Bit Rate (ABR) service has been developed to support data applications over Asynchronous Transfer Mode (ATM). It is hence interesting to study the performance of reliable data transport protocols like the \Transport Control Protocol (TCP)" over ABR. We study the eeect of running large unidirectional le transfer applications on TCP over ABR(More)
The Available Bit Rate (ABR) service has been developed to support data applications over Asynchronous Transfer Mode (ATM). The ABR service uses a closed-loop rate-based traac management framework where the network divides available bandwidth among contending sources. The ATM Forum then worked on incorporating open-loop control capabilities to make the ABR(More)
We propose BANANAS a connectionless framework for both intra domain and inter domain tra c engineering TE in the Internet The key contributions of this framework are a it allows the source to discover multiple paths and decide on how to split tra c among paths assuming simple for warding extensions in a subset of routers b it does not require signaling or(More)

ATM switches respond to UBR congestion by dropping cells when their buffers become full TCP connections using the UBR service experience low throughput and low fairness For TCP throughput each switch needs buffers equal to the sum of the window sizes of all the TCP connections Intelligent drop policies can improve the performance of TCP over UBR with(More)
In this paper, we propose and study a novel transport protocol that can effectively utilize available bandwidth and diversity gains provided by heterogeneous, highly lossy paths. Our Multi-Path LOss-tolerant Transport (MPLOT) protocol can be used to provide significant gains in the goodput of wireless mesh networks, subject to bursty, correlated losses with(More)
The Asynchronous Transfer Mode (ATM) networks are quickly being adopted as backbones over various parts of the Internet. This paper analyzes the performance of TCP/IP protocols over ATM network's Available Bit Rate (ABR) and Unspeciied Bit Rate (UBR) services. It is shown that ABR pushes congestion to the edges of the ATM network while UBR leaves it inside(More)
We extend our earlier studies of buuer requirements of TCP over ABR 10, 11, 12] in two directions. First, we study the performance of TCP over ABR in an ATM backbone. On the backbone, the TCP queues are at the edge router and not inside the ATM network. The router requires buuer equal to the sum of the receiver window sizes of the participating TCP(More)
