With the popularity of smart devices in a variety of actions to drive more usage of wireless broadband networks. OTT refers to delivery of video, audio and other media over the Internet. The video-related applications and services are major challenges that impact the network performance in the future. It is important to achieve network and service traffic offloading to overcome high-speed, real-time,...
Cluster technology has witnessed a tremendous inception in computing world. The technique integrates the standard computing resources to generate more processing power and other hardware strengths. The collection of interconnected stand-alone computers ensures high availability, increased throughput, scalability and improved performance. We have developed a dynamic cluster based approach for high...
In lossless interconnection networks congestion control (CC) can be an effective mechanism to achieve high performance and good utilization of network resources. Without CC, congestion in one node may grow into a congestion tree that can degrade the performance severely. This degradation can affect not only contributors to the congestion, but also throttles innocent traffic flows in the network. The...
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...
Oblivious routing can be implemented on simple router hardware, but network performance suffers when routes become congested. Adaptive routing attempts to avoid hot spots by re-routing flows, but requires more complex hardware to determine and configure new routing paths. We propose onchip bandwidth-adaptive networks to mitigate the performance problems of oblivious routing and the complexity issues...
Internet traffic is a mixture of unicast and multicast flows. Integrated schedulers capable of dealing with both traffic types have been designed mainly for Input Queued (IQ) buffer-less crossbar switches. Combined Input and crossbar queued (CICQ) switches, on the other hand, are known to have better performance than their buffer-less predecessors due to their potential in simplifying the scheduling...
