| Real-time distribution of stored video over wide-area networks is a crucial component of many emerging distributed multimedia applications. The heterogeneity in the underlying network environments is an important factor that must be taken into consideration when designing an end-to-end video delivery system. In this paper, we present a novel approach to the problem of end-to-end video deliver...

Real-time distribution of stored video over wide-area networks is a crucial component of many emerging distributed multimedia applications. The heterogeneity in the underlying network environments is an important factor that must be taken into consideration when designing an end-to-end video delivery system. In this paper, we present a novel network-conscious approach to the problem of end-to-e...

The design of a platform for bi-directional musical performance using modern WAN networks poses several challenges that are different from related applications, e.g., synchronous LAN studio systems or uni-directional WAN streaming. The need to minimize as much as possible audio latency and also maximize audio quality requires specific strategies which are informed, in part, by musical decisions...

Compression-performing modems significantly improve the file transfer process over LANs. The use of compression technology can provide even more effective results when applied to WAN. The use of compression-performing bridges or routers can reduce WAN bottlenecks, eliminate or reduce time-out problems caused by time-sensitive legacy mainframe communications protocols, and eliminate or postpone ...

To allow a seamless integration between wireless LANs and Wireless WANs, we developed a full stack adaptation model and a simple subnet architecture that superimposes Mobile-IP on cellular-type wireless LANs. The idea is to use Mobile IP as an integrative layer atop different LAN/WAN networks. While Mobile-IP is widely used in wireless WANs, it is not known how well it performs under a wireless...

The International Maritime Satellite (Inmarsat) communication service can be used to provide a wide area network (WAN) connection for a local area network (LAN) to the home LAN from almost anywhere on the earth. The communication link of the WAN connection is achieved through the satellite network of Inmarsat and a land-earth digital telephone network, such as Integrated Services Digital Networ...

This paper presents the architecture of a complete communications platform for sensor-based applications. It covers from the direct communication with the sensors themselves to the most remote application modules. It has been divided into three levels: BAN (Body Area Network), LAN (Local Area Network) and WAN (Wide Area Network), and it uses wireless communications at all levels of the architec...

In today’s class, we cover the topic of the Internet with emphasis on review of TCP/IP. ( A good reference is [1] and a slightly more readable but less comprehensive is [2] I. NETWORKS Communication networks are usually defined by their size and complexity. From top-down, we have • Wide area networks(WAN) These networks connect computers and other terminals over large distances. They often requ...

The paper provides a survey of network traffic models. It starts from the description of the Poisson model, born in the context of telephony, and highlights the main reasons for its inadequacy to describe data traffic in LANs and WANs. It then details two models which have been conceived to overcome the Poisson model's limitations. In particular, the discussion focuses on the packet train model...
