Many Layered Multicast (LM) congestion control schemes have been proposed to serve different users with heterogeneous bandwidth requirements. Most of the LM algorithms suffer from a large IGMP leave latency and a sudden rate increase. Layered Increase/Decrease with Dynamic Layering (FLID-DL) was introduced to address these challenges. Nevertheless, FLID-DL can neither provide very good bandwidt...

In this paper we extend Multi-level ECN, a new TCP congestion scheme, which we have proposed previously. The Multi-level Explicit Congestion Notification (MECN) algorithm allows network operators to achieve high throughput with corresponding low delays. But MECN average queue, is sensitive to its parameter settings and its the level of congestion, hence no guarantees can be given about delay. D...

In the TCP over Wireless Internet Networks (WINs), TCP responds to losses such as high bit errors and handovers by invoking congestion control and avoidance algorithms. In this paper we propose new handover notification algorithm that is to send an explicit handover notification message to the source host from mobile host when occurring to handover. Upon receipt of explicit handover notificatio...

We investigate the service differentiation, in terms of average throughput, and the performance achieved using weighted window-based congestion control in networks supporting Explicit Congestion Notification (ECN). Our results show how service differentiation, queueing delay, and average throughput are affected by the increase and decrease rules of the end-system congestion control algorithms, ...

This document describes a possible congestion control mechanism for acknowledgement (ACKs) traffic in TCP. The document specifies an end-to-end acknowledgement congestion control mechanism for TCP that uses participation from both TCP hosts: the TCP data sender and the TCP data receiver. The TCP data sender detects lost or Explicit Congestion Notification (ECN)-marked ACK packets, and tells the...

In case that malicious or selfish user congests network, the traditional congestion control schemes such as ECN (Explicit Congestion Notification) in TCP protocol could not control the pernicious congestion so perfectly as they protect normal traffic. In this paper, we propose a strong congestion-making traffic control scheme, which is capable of preventing malicious or selfish user from conges...

This document specifies Non-Congestion Robustness (NCR) for TCP. In the absence of explicit congestion notification from the network, TCP uses loss as an indication of congestion. One of the ways TCP detects loss is using the arrival of three duplicate acknowledgments. However, this heuristic is not always correct, notably in the case when network paths reorder segments (for whatever reason), r...

CONGESTION MANAGEMENT FOR LOSSLESS ETHERNET OPERATION by Jinjing Jiang ADVISOR: Professor Raj Jain May 2008 Saint Louis, Missouri IEEE 802.1 standards committee is working on a new specification for congestion notification in Ethernet networks. The goal of this work is to enable applications of Ethernet in backend data center networks. Such applications typically use Fiber Channel and Infiniban...
