Generalized Multi-Protocol Label Switching (GMPLS) has become the protocol suite of choice for unified control plane implementation. However, its adoption is facing major challenges in terms of feasibility, performance, and gain when migrating from legacy packet over optical multi-layer networks driven by overlaid control planes. The ITEA TBONES project aims at tackling both objectives through the development of a platform including all the elements constituting such networks: network dimensioning, management plane and GMPLS control plane. This paper details the control plane architecture of the TBONES software platform, including its realization and applicability for multi-area networks, as well as the Testbed. Several experiments are described, both for validation and for demonstration of its capabilities and future usage.

“…The blocking probability is formulated by using Erlang B formula because it calculates the blocking probability of a buffer-less loss system, where a request that is not served immediately gets aborted, causing that no requests become queued [29]- [31]. Blocking occurs when a new request arrives at a time where all available servers are currently busy [32], [33].…”

Generalized Multi Protocol Label Switched (GMPLS) optical networks increase the network capacity by allowing large number of parallel links between nodes in a network which is the basic requirement in optical communication where hundreds of parallel links may exist between a pair of nodes. It also facilitates switchovers to alternate channels, rapid fault detection, fault isolation and reducing network downtime. In this paper, GMPLS network is proposed with dynamic users. Then the different bandwidth allocating algorithms have been implemented on the proposed GMPLS optical networks. The various algorithms involve Minimum Execution Time (MET) algorithm, Minimum Completion Time (MCT) algorithm and Opportunistic Load Balancing (OLB) algorithm. The considered algorithms are very popular but have not been implemented on GMPLS optical networks in the literature which shows the novelty of the work. The network performance is evaluated for each algorithm and compared with each other. The results reveal that MET reduces the blocking probability < 0.1% and latency < 1ms. This shows that MET gives the best performance among the considered algorithms and enhance the quality of service in terms of blocking probability, latency, makespan and energy consumption in GMPLS optical networks.INDEX TERMS Bandwidth allocation, blocking probability, GMPLS.

“…With the rapid development of telecommunication network, computer network and broadcast network, network architecture is in the process of evolution towards NGN. "network integration" is an important solution for future network development [1] , although IP/MPLS over WDM is considered as the best solution for NGN, but telecommunication provider will hold the existing telecommunication services and network technology which can bring income while introducing new network technology, therefore network architecture is three-layer of IP/MPLS over SDH over WDM in future for a long time.…”

IP/MPLS over WDM is regarded as the best solution for NGN (next generation network), but in current and future for a long time, network architecture is still three-layer of IP/MPLS over SDH over WDM. In order to make full use of resources and reduce the blocking probability in three-layer dynamic network, an integrated resources optimization algorithm is proposed. We propose two optimization modes in our algorithm: in optimization mode 1, the service blocked in upper layer can be transmitted in lower layer by its idle resources; in optimization mode 2, we regard the three-layer network as an integrated network and search route for each service in the integrated network. In order to transport each service in synchronous manner, an ACO-based routing approach is adopted in these two modes. The simulation results show that compared with other algorithms, our algorithm gets better performance than other routing approaches in terms of service blocking probability.
