“…To address the problem of load balancing, the scheme attempts to minimize the gap between the maximum and minimum available bandwidth of physical links. Mirjalily et al proposed a series of schemes to improve the network efficiency of Ethernet . Best spanning tree is an algorithm that selects one of the spanning trees built by various methods.…”

“…If a blocked link connects to the destination switch of a frame, the blocked link acts as a shortcut path for frame forwarding by using MAC‐in‐MAC encapsulation. Enhanced Forwarding Strategy (EFS) improves shortcut switching strategy by reporting the destination MAC address and the nexthop switch of a frame to the predecessor switch of the frame . If there is a blocked link between the predecessor and nexthop switches, the blocked link will be used for forwarding subsequent frames with the same destination MAC address.…”

Failure recovery is a critical performance issue in large-scale Ethernet networks. The standard mechanisms of link-failure recovery in spanning tree protocol (STP) and rapid STP may cause interruptions of data transmission because of long recovery time. Several previous approaches construct multiple alternative trees to avoid such interruptions caused by single or multiple failed links based on multiple STP. However, the prototypical protocol of standard root election would result in the same root switch for different spanning trees. Hence, the alternative trees may become invalid if a failed link appears in more than 1 spanning tree. Our scheme, failure-adaptive spanning trees (FAST), improves the resilience of Ethernet with multiple spanning trees. It avoids simultaneous faults of multiple spanning trees by incorporating a new approach to electing an appropriate root switch for each spanning tree. Failure-adaptive spanning trees also use active links of alternative spanning trees for data transmission. The paths of different spanning trees can thus act as shortcuts to shorten frame paths. The experimental results demonstrate that FAST can sustain network throughput under multiple link failures. The FAST also balances both link and switch loads.

“…More information is available in [1][2]. In our previous works, we have proposed some solutions to resolve the problem of load balancing in Ethernet networks [3][4][5][6][7][8][9]. In [3], three load balancing criterions are defined: load balancing over links, load balancing on switches and shortest path selection.…”

“…In [6][7], a simple approach named Shortcut Switching Strategy (SSS) is proposed that provides some shortcut paths through the blocked links. In [8], the idea of shortcut switching is extended by using the hierarchical addressing, while in [9], an enhanced forwarding strategy named Isolated Forwarding Strategy (IFS) is introduced, where the blocked links are used to forward traffic between subtrees in an isolated fashion.…”

<p>Creation and maintenance of the spanning tree forwarding topology is an essential task in Ethernet networks. In standard Ethernet networks, Spanning Tree Protocol (STP) is responsible to do this task. In STP, some links will be disabled to provide a minimum-cost spanning tree. However, the constructed tree may be unbalanced. STP does not provide any mechanism for load balancing, results in unbalanced distribution of the traffic load and this may lead to congestion. In this paper, a new protocol named Balanced Spanning Tree Protocol (BASTP) is proposed to provide a balanced spanning tree in hierarchical topologies for using in next generation (NextGen) wired networks. Simulation results show that BASTP provides better load balancing and therefore better performance in comparison to the standard STP.</p>
