We analyze the conditions in which offloading computation reduces completion time. We extend the existing literature by deriving an inequality that relates computation offloading system parameters to the bits per instruction ratio of a computational job. This ratio is the inverse of the arithmetic intensity. We then discuss how this inequality can be used to determine the computations that can benefit...
The past century of telecommunications has shown that failures in networks are prevalent. Failure recovery processes are therefore needed. Failure recovery is mainly influenced by (1) detection of the failure, and (2) circumvention of the detected failure. However, especially in SDNs where controllers recompute network state reactively, this leads to high delays. Hence, next to primary rules, backup...
Responsive Real-Time Collaborator with Audio Channel, or simply, RTCollaborator, is a user- friendly web application using a responsive layout web design that supports voice and text chat and also has a shared board tool. The application allows users to draw on the board, make flowchart diagrams and see each other's changes, drawings and writings at real- time.
In the research of content-centric networking (CCN), there have been investigated several fragmentation methods of CCN messages in order to implement CCN as an L3 protocol. The latest version of the CCN protocol (CCN 1.0) adopts the end-to-end fragmentation method that fragments CCN messages only at the content publisher. This allows intermediate routers to simply forward fragmentation packets, and...
Flow-Aware Multi-Topology Adaptive Routing (FAMTAR) is a new mechanism which provides the ability to use multiple paths between two points in a network. When the primary path becomes congested, a new path is found and used. However, when all possible paths are congested, new flows are still accepted on one of the congested paths which degrades the observed quality of service. Therefore, in this paper,...
Nowadays, one of the main problems of mobile operators is to handle network traffic more resourcefully. Techniques, which increase the traffic capacity over the mobile core with minimum costs, play a fundamental role. Following advent of smart phones, the most of the traffic bandwidth is being used for connecting to external IP networks, like the Internet. Consequently, this overloaded traffic causes...
In this paper we introduce a distributed channel change framework that utilizes a dedicated server and session peers to support the fast channel change process. Support peers represent the prior choice to deliver the channel change packets to the zapping users. The dedicated server, which we refer to as the Channel Switch Coordinator (CSC), is essentially responsible for the coordination of the channel...
