“…• strictly partition priority evaluation from state machine • reduce any possible bugs in tables of state transition Based on the obtained results in [12], we can relate that this developing unified solution is proven to have backward compatibility with the installed equipment and it is applicable to other topologies i.e: ring and shared mesh protection switching.…”

“…Based on the obtained results in [11], we can relate that no loss of packets happened during the restoration process due to the merging selector, even when traffic has been rerouted from faulty path to the working path. The compatibility and applicability of MPLS-TP in [12] can be decided using a unified linear protection switching mechanism which is APC. It has been introduced in conjunction with the preexisting solutions as well as the other topologies of network.…”

“…Determinism criteria in MPLS-TP network is developed by using deterministic method, where the produced output is always the same regardless of the input. This can also be described as protection, proposed by several researchers in [11][12][13][14][15]. Kim et al [11] suggested a new MPLS-TP linear protection mechanism which is known as an Optical Carrier Ethernet Switch (OCES) by using the existing Protection State Coordination (PSC) format.…”

“…In addition, this mechanism can be implemented regardless of network topologies, either in ring or shared mesh protection switching. PSC and APS are pre-existing solutions for the MPLS-TP linear protection with some deficiencies, thus, an Automatic Protection Coordination (APC) has been introduced by Ryoo et al [12] as a unified solution which could improve both of the PSC and APS solutions.…”

In the perspective of Multiprotocol Label Switching – Transport Profile (MPLS-TP) network, a reliable framework architecture or mechanism needs to be ascertained by comparing the results obtained through implementation of previously proposed scheme towards the network. This is important in order to implement an efficient system for different types of applications or services. Various results are reviewed and analyzed from the related works followed by detail discussions based on their proposed objectives. The analyses shown that most applications of MPLS-TP have been utilized for protection, followed by Operations, Administration and Maintenance (OAM), fairness and congestion control. This is due to the mission-critical operational service of protection which require us to meet the standard protection switching time of 50 ms.

Minimizing protection switching time in transport networks with shared mesh protection

Summary Shared mesh protection (SMP) protects service traffic on a working path and requires coordinated use of the shared resources on a protection path when the traffic is routed through the protection path. If there are many intermediate nodes on the protection path, the delay caused by the coordination at each node increases the protection switching time, resulting in losing more traffic. Considering the capacity of a link and the bandwidth required by the protection paths using that link, it appears that coordination is necessary. However, looking closely at the relationships with other links and their protection paths, there exist resources that may require no coordination at all. This observation leads to the fact that protection switching time can decrease when bypassing some intermediate nodes for coordination. This fact introduces an optimization problem, in which the objective is to exclude these resources as much as possible from the set of resources for which coordination is required. A sub‐problem is finding these excludable candidate resources. For both the main problem and the sub‐problem, which are NP‐hard, we propose a greedy algorithm and a branch‐and‐bound algorithm, respectively. The simulations show that the results using the proposed algorithms are near‐optimal. Furthermore, in an actual topology configured with the SMP environment, the protection switching time is improved by excluding resources for which coordination is not required, compared to the existing Optical Transport Network (OTN) SMP mechanism.
