In bufferless optical burst/packet switched (OBS/OPS) networks, data (bursts or packets) may be lost due to contention or equipment failure. Diversity coding-based path protection schemes can be used to protect data from a single-trunk-failure with potentially more efficient resource utilization compared to dedicated (e.g. 1+1) path protection schemes and help reduce the burst/packet loss ratio. This paper provides a scalable and accurate burst/packet loss ratio approximation based on the Erlang Fixed-Point Approximation for networks that employ protection based on diversity coding and for networks that employ protection based on both diversity coding and 1+1 path protection. We use discrete event simulations to assess the accuracy of the approximation based on a wide range of and scenarios in a 10-node circular lattice and NSFNet networks. Further, we discuss the effect of parameter settings and the effect of the choice of the wavelength selection method on the accuracy of the approximation. We consider scenarios without wavelength conversion and with full wavelength conversion and two types of users: premium and regular. The premium users, typically of mission critical services, receive protection while the regular users do not. We compare diversity coding and 1+1 path protection in a 10-node circular lattice network. The results show that for this example network, for the premium users and under low traffic load, the burst/packet loss ratio in OBS/OPS networks is lower for diversity coding compared to 1+1 path protection. However, under heavy traffic load, we observe a lower loss ratio for the case of 1+1 path protection.

“…These costs must be taken into account while determining the resource saving effect of traffic splitting. To overcome this issue, Muktadir et al [8] introduced a differential delay-aware instantaneous recovery scheme with traffic splitting in order to tackle multiple link failures, for networks with the coding capability.…”

“…Taking this direction, different coding based protection scenarios, such as, traffic splitting (T S) [5][6][7][8][9] and two sources and a common destination (2S D) [10][11][12][13], have been introduced; the T S and 2S D protection scenarios are explained in Sect. 3.…”

This paper proposes an instantaneous recovery route design scheme using multiple coding-aware link protection scenarios to achieve higher link cost reduction in the network. In this scheme, two protection scenarios, namely, (i) traffic splitting (T S), and (ii) two sources and a common destination (2S D) are used to integrate multiple sources and a common destination. The proposed scheme consists of two phases. In the first phase, the proposed scheme determines routes for 2S D and T S scenarios of all possible sourcedestination pairs to minimize the total link cost. In this phase, the network coding is applied to the common path within each scenario, individually. In the second phase, network coding is applied to the common path between two scenarios (or a scenario pair) in order to enhance the resource saving. This phase develops conditions that select the most appropriate combination of scenario pairs, such as T S-T S, 2S D-2S D, and 2S D-T S for network coding, including their proofs. Using these conditions, a heuristic algorithm is introduced in order to select the most appropriate combination of scenario pairs for further enhancing of resource saving. Simulation results show that the proposed scheme outperforms the conventional 1 + 1 protection scheme, the T S scenario, and the 2S D scenario in terms of link cost reduction in the network.
