Abstract:
Increasing traffic demands in the transport networks as well as declining revenues per bits require an increased transport efficiency. The concept of network coding has shown to increase the network throughput in capacity limited networks compared to traditional routing solutions. We show in this paper that applying network coding to certain reference transport networks with traffic protection reduces the required transport resources thus improves the network efficiency. Besides investigating the achievable resource savings we elaborate constrains and limiting factors for the performance and application of network coding in transport networks with a 1+1 path protection.
