[email protected] o v e r t h e pa S t d e c a d e , t h e p e e r -t o peer (P2P) model for building distributed systems has enjoyed incredible success and popularity, forming the basis for a wide variety of important Internet applications such as file sharing, voice-over-IP (VoIP), and video streaming. This success has not been universally welcomed. Internet Service Providers (ISP...

Abstract Optical mesh networks using intelligent optical cross-connects are the choice for the next generation optical core. Mesh networks can be designed for fast and guaranteed recovery from single failures and can be designed to protect traffic more efficiently via shared mesh restoration. In this paper, we present a mesh restoration architecture for the optical core. The architecture provid...

WLAN IEEE 802.11 Networks should be designed primarily for capacity. In a typical infrastructure WLAN network, now it demands more devices to connect in single network since business-critical applications rely on a Wi-Fi network also the amount of data transmitted wirelessly has significantly increasing which includes voice calls made over Wi-Fi, HD video streaming through Wi-Fi, file access an...

We propose a cross-layer optimization strategy that jointly optimizes the application layer, the data-link layer, and the physical layer of a wireless protocol stack using an application-oriented objective function. The cross-layer optimization framework provides efficient allocation of wireless network resources across multiple types of applications run by different users to maximize network r...

Wireless mesh networks are the next step in the evolution of wireless architecture, deliveringservices for a large variety of applications in personal, local, campus, and metropolitan areas.Supporting multimedia services in wireless mesh networks is receiving more attention from theresearch community. While wired networks have mature infrastructure and protocols providingQoS for...

With the success of P2P file sharing, new emerging P2P applications arise on the Internet for streaming content like voice (VoIP) or live video (IPTV). Nowadays, there are lots of works measuring P2P file sharing or P2P telephony systems, but there is still no comprehensive study about P2P IPTV, whereas it should be massively used in the future. During the last FIFA world cup, we measured netwo...

We analyze the performance of MAC-layer Reed-Solomon error-recovery in the cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCS) environment, with respect to the size of the error control block (ECB) and the air-channel condition, and establish the relationship between ECB size, error-recovery capacity and service latency. Real-time traffic, such as voice and video streaming, is very sensit...

Although the equipment currently available for Ethernet LANs provides basic quality of service (QoS) capabilities, as the ability of prioritizing traffic flows, it does not support more complex mechanisms like admission control or the ability of participating in a signalling process. This paper presents a survey on the QoS support and on resource allocation for LAN Ethernet networks, and descri...

Multipath routing protocols have proved to be able to enhance the performance of MANET in terms of reliability, load balancing, multimedia streaming, security, etc. However, deploying a QoS framework on top of such routing protocols is a complex task, requiring an appropriate QoS strategy to be developed and deployed. In this paper we propose an admission control strategy that can operate both ...

Internet technology is advancing with increasing internet applications demands. However, most developing countries have poor internet experience. Thus, the Quality of Service, QoS of an internet technology, Third Generation, 3G in a developing country, Nigeria was studied. Voice over internet protocol, VoIP and Video Streaming were the internet applications while CODECs and node density were th...
