Border Gateway Protocol (BGP) is a dynamic routing protocol in the Internet that allows Autonomous System (AS) to exchange information with other networks. The main goal of BGP is to provide a loop free path to the destination. Security has been a major issue for BGP and due to a large number of attacks on routers; it has resulted in router misconfiguration, power failure and Denial of Service ...

Energy consumption control in wireless ad-hoc networks is a more difficult problem due to non availability of access point in network. A node can be both a data source and a router that forwards data for other nodes. There is no centralized entity such as an access point to control and maintain the power control mode of each node in the network. There are number of challenges offered by mobile ...

increasing the number of cores integrated on a chip and the problems of system on chips caused to emerge networks on chips. nocs have features such as scalability and high performance. nocs architecture provides communication infrastructure and in this way, the blocks were produced that their communication with each other made noc. due to increasing number of cores, the placement of the cores i...

This paper proposes a new approach to providing fault tolerance in MPLS networks based on the concept of “domain protection” where protection paths for all working paths that terminate in an egress router are calculated simultaneously. The proposed scheme guarantees that every protected node is connected to two protection paths placed in a way that no single link failure would cause simultaneou...

we design and simulate a five-port optical router, which is composed of twenty mach-zehnder-based switching elements and twelve waveguide crossings for use in integrated photonic interconnection networks. we simulated and analyzed the operation of the proposed optical router from the aspects of insertion loss, power budget, q-factor and the minimum bit error ratio by use of optisystem simulator...

Switch Allocation (SA) holds a critical stage in Network-on-Chip (NoC) routers, its performance gets affected adversely due to Head-of-Line (HoL) blocking. In traditionally used Input-Queued Routers (IQR), packets are arranged particular order each Virtual Channel (VC). This implementation is vulnerable HoL blocking, as the switch allocator can allocate only those which available at head VC. th...

The constant reduction in the size of components of integrated circuits, as well as the growing operating frequency, increases the vulnerability to internal and external noise sources. These noises can cause a failure in any component, affecting the functioning of the system as a whole. Future Systems-on-Chip with dozens of cores will be based on Networks-on-Chip (NoCs), and will require networ...
