We present the source-tree adaptive routing (STAR) protocol, which we show through simulation experiments to be far more efficient than the Dynamic Source Routing (DSR) protocol, which has been shown to be one of the best performing on-demand routing protocols. A router in STAR communicates to its neighbors the parameters of its source routing tree, which consists of each link that the router n...

Wi-Fi technology has always been an attractive solution for catering the increasing data demand inmobile networks because of the availability ofWi-Fi networks, the high bit rates they provide, and the lower cost of ownership. However, the legacyWiFi technology lacks of seamless interworking betweenWi-Fi and mobile cellular networks on the one hand, and between Wi-Fi hotspots on the other hand. ...

As interest in IPv6 deployment in cellular networks increases, several migration issues have been being raised; IPv6 prefix management is the issue addressed in this document. Based on the idea that DHCPv6 servers can manage prefixes, we use DHCPv6 Prefix Delegation to address such prefix management issues as an access router offloading delegation of prefixes and release tasks to a DHCPv6 serve...

Programmable networks offer the ability to customize router behaviour at run time, thus increasing flexibility of network administration. Programmable network routers are configured using domain-specific languages. The ability to evolve router programs dynamically creates potential for misconfigurations. By exploiting domain-specific abstractions, we are able to translate router configurations ...

The model is a service system, consisting of several large server pools. A server processing speed and buffer size (which may be finite or infinite) depend on the pool. The input flow of customers is split equally among a fixed number of routers, which must assign customers to the servers immediately upon arrival. We consider an asymptotic regime in which the customer total arrival rate and poo...

High throughput, low latency and high system availability are the most important criteria for an internet router. Internet Router‟s complexity has been on constant rise to serve the exploding internet backbone. With rise in design complexity comes the increased possibility of bugs escaping into silicon and affecting the user at runtime. In this project we provide a runtime verification scheme f...

Currently, most of Network on-Chip (NoC) architectures have some limitation in routing decisions. And it makes router nodes overloaded, and sequentially forms deadlock, livelock and congestion. A simple unbuffered router microarchitecture for S-mesh NoC architecture is proposed in this paper. Unbuffered router transforms message without making routing decision. Simulation results showed that S-...

Performance results and synthesized area overhead for a code division multiple access (CDMA) router intended for network-on-chip (NoC) applications are presented. Specific architectural block diagrams of the main components of the router are given and synthesis results are provided for 0.18 micron and 0.25 micron structured ASIC libraries. Post-synthesis VHDL simulations verify the functionalit...

An Internet router was integrated into the UK-DMC remote-sensing satellite as a secondary experimental payload. This commercial product has been orbiting in space for over three years. We describe the integration of the router and satellite and the successful on-orbit testing of the router, which took place using the Virtual Mission Operations Center (VMOC) application as part of a larger syste...

NoC designs are based on a compromise of latency, power dissipation or energy, usually defined at design time. However, setting all parameters at design time can cause either excessive power dissipation (originated by router underutilization), or a higher latency. The situation worsens whenever the application changes its communication pattern, i.e., a portable phone downloads a new service. Th...
