Home networks are becoming increasingly com-plex, with many household devices (PCs tablets, phones, media gateways, smart TVs) and diverse user applications (browsing, video streaming, peer-to-peer, VoIP, gaming) sharing the single broadband access link. In today's architecture the traffic streams compete for bandwidth on a best-effort basis, resulting in poor quality of experience for users. In this...
With the development of the Internet, the requirement of the unified network computing and storage will continue to increase, which will make the high speed transmitting technology to be adopted more widely. With the advantages of high speed and reliable, InfiniBand technology could load other protocol data units, and bring the convergence of InfiniBand and Ethernet. In this paper the conversion technologies...
Three requirements for leased-line service in a packet-transport system are determined such as service availability of 99.999%, bandwidth guarantee of 100%, and latency of 10 ms via 20 nodes. To meet these requirements, network architecture is proposed which includes the separation of control function and data-transmission function and shaping per flow at the entrance of a network. Nodes and gateways...
This paper describes a methodology for building a reliable internet core router that considers the vulnerability of its electronic components to single event upset (SEU). It begins with a set of meaningful system level metrics that can be related to product reliability requirements. A specification is then defined that can be effectively used during the system architecture, silicon and software design...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
