A novel routing architecture that balances incoming traffic over the Agile All-Photonic Network (AAPN) is proposed. The architecture is based on the adaptive highest random weight (Adaptive HRW) algorithm proposed to design load balanced internet routers. It extends the adaptive HRW algorithm by assigning balancing weights to each source-destination edge node pair in the network. The weights are adapted...
Traffic engineering is a mechanism to use network resources more efficiently. Network operators use TE to obtain different objectives such as load balancing, congestion avoidance and average delay reduction. Plane IP routing protocols such as OSPF, a popular intradomain routing protocol, are believed to be insufficient for TE. OSPF is based on the shortest path algorithm in which link weights are...
Unlike traditional routing schemes that route all traffic along a single path, multipath routing strategies split the traffic among several paths in order to ease congestion. It has been widely recognized that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. aiming at the increasing network traffic and the deficity that the former Ant...
A load balancing algorithm functioning as an extension to the topological routing scheme is proposed. The algorithm is designed to evenly distribute the traffic load in a 4-regular grid network. This is done by letting each node calculate how loaded it is with regular intervals and feed this information to its neighboring nodes, which then use it to derive link probabilities applied in probabilistic...
Wireless mesh networks (WMNs) have attracted increasing attention from the research community as a high-performance and low-cost solution to last-mile broadband Internet access. However, it remains an open challenge to provide mesh clients with efficient handoff among different mesh routers. In this paper, we address channel switching efficiency and load balancing capability during the handoff process...
To avoid congestion caused by some nodes overloaded and mesh points (MPs) becoming bottleneck in wireless mesh networks (WMNs), this paper proposed a new routing protocol called CLDSR-LB (cross-layer dynamic source routing protocol with load balancing). In order to avoid nodes overloaded, CLDSR-LB utilizes the idea of multi-metric and cross-layer and selects an optimal route by estimating the residual...
Multi-nexthop routing mechanisms is the key point in network congestion, and the essential question is how to forward packets among multi-nexthop to reach equiponderant forwarding. This paper proposes an equiponderant forwarding strategy in multi-nexthop routing, which forwards the packets according to the actual capability of each node, and resolves the equiponderant forwarding problem of multi-nexthop...
Multi-radio wireless mesh networks (MR-WMNs) are being increasingly deployed to provide affordable Internet access on large residential areas. MR-WMNs allow the supported mesh clients (MCs) to access the Internet gateway by multi-hop packet forwarding over the mesh routers (MRs), which can be equipped with multiple radio interfaces. In such a scenario, the routing protocol should (i) decide the address...
Internet service providers have to provision network resources to optimize bandwidth utilization. Dynamic routing protocols take traffic variations into account to control the load distribution. Multipath routing protocols attempt to take advantage of the path diversity to bring network robustness and reliability. Indeed, with a specific traffic engineering policy, they enable load balancing across...
