Multicast Virtual Network Services Embedding for Improved Disaster Recovery Support

Multicast virtual network (MVN) cloud services have tight restrictions in terms of coverage, delay, delay variation, and reliability. However large disasters impose key challenges, and there are no known solutions that incorporate stochastic multi-failure risk into the MVN embedding process. Hence, this letter presents novel proactive “risk-aware” MVN mapping algorithms to improve resiliency and also incorporate efficiency. Simulation results show that the proposed schemes yield substantial performance gains versus existing MVN survivability methods.
