Network congestion control is a critical issue, especially in the growing size, demand, and speed (bandwidth) of the increasingly integrated services networks. Designing effective congestion control strategies for these networks is a challenge because of the complexity of the structure of the networks, nature of the services supported, and the variety of the dynamic parameters involved. Congestion...
As current Internet frontiers are rapidly extending towards space, the scientific community's interest is increasingly addressed to next-generation network architectures suited to enable data communications over interplanetary networks. In this light, given the networking and communication challenges posed by such environments, the design of complex telecommunication infrastructures deserves particular...
Random Early Detection (RED) can effectively avoid transmitting congestion at routers, but RED can not provide bandwidth fairness. Different packet sizes are one of the reasons that damage fairness. RED routers provide little protection from some bulky data flows that use considerably more bandwidth than other flows in time of congestion. Modifying the formulas of calculating final packet-discard...
Significant progress has been made in understanding the behavior of TCP and congestion-controlled traffic over multi- hop wireless networks. Despite these advances, however, no prior work identified severe throughput imbalances in the basic scenario of mesh networks, in which one-hop flows contend with two-hop flows for gateway access. In this paper, we demonstrate via real network measurements, test-bed...
Based on the comparison of congestion control between aeronautical telecommunication network (ATN) and IP network, a new congestion avoidance model considering the explicit congestion notification (ECN) in ATN over IP scheme, called explicit congestion notification in tunnel (ECNT) model, is proposed in this paper. In addition, a new ECN/CE mapping algorithm to map ECN signal in IP sub-network onto...
Based on the concept of contention reservation for polling transmission and collision prevention strategy for collision resolution, a fair on-demand access (FODA) protocol for supporting node mobility and multihop architecture in mobile ad hoc networks is proposed. In the protocol, a distributed clustering architecture and an idea of reserving channel resources to get polling service are adopted,...
One of the vital key elements for providing quality of service (QoS) for VoIP is the call admission control (CAC) capabilities of the session management/call session control function or gateway. Even though the network may be designed to meet a given performance and restoration objective for the engineered traffic loads, the actual traffic may be significantly higher. Without a CAC function in a VoIP...
