Congestion Control performs a very important role in Computer Networks, Modern Telecommunication, Internet and both wired and wireless communications are being intended for high-speed communication of large amounts of data. Due to lack of proper Congestion control mechanism the congestion collapse of such networks would become highly complex. A network with Streamed media traffic is a challenge...

TCP congestion control was designed and optimized for wired networks. During recent years, however, the popularity of wireless network infrastructures enabling ubiquitous Internet access, such as Universal Mobile Telecommunication System (UMTS), has grown considerably. As a consequence, many improved TCP congestion control algorithms, able to effectively operate over hybrid wired/wireless netwo...

Modern telecommunication and computer networks, including the Internet, are being designed for fast transmission of large amounts of data, for which Congestion Control Algorithms (CCAs) are very important. Without proper CCAs, congestion collapse of such networks is a real possibility. Random tele-traffic is a heterogeneous mixture of streams of data packets that have different quality-of-servi...

ABR is an emerging ATM-based telecommunication service which dynamically allocates bandwidth to the users according to the available bandwidth in the network. However, research shows that ABR-based connections suuer from congestion at LAN-ATM gateway when ATM network abruptly reduces bandwidth available to the gateway. Gateway congestion may result in high packet loss. This article proposes a g...

Available bit rate (ABR) is an emerging asynchronous transfer mode (ATM)-based telecommunication service, which dynamically allocates bandwidth to the users according to the available bandwidth in the network. However, research shows that ABR-based connections suffer from congestion at LAN–ATM gateway when ATM network abruptly reduces the bandwidth available to the gateway. Gateway congestion m...

Rapid development of telecommunication technologies and the ever growing network users demands have made network congestion a prominent problem in today’s Internet. Congestion not only brings significant performance degradation to the network, but also hurts the Quality-of-Service (QoS) that the users receive and even raises up some security concerns such as Denial-of-Service (DoS) attacks. The...

Virtualization of network functions and services can significantly reduce capital and operational expenditures of telecommunication operators through the sharing of a single network infrastructure. However, the utilization of the same resources can increase their congestion due to the spatio-temporal correlation of traffic demands and computational loads. In this paper, we propose novel orchest...
