The present disclosure proposes a mechanism to improve network efficiency and resource utilization in Retain Home Path (RHP) enabled control plane networks. With optimized resource allocation, networks will be allowed to accommodate a larger number of services without losing RHP capability of existing services. The disclosure provides a way to work with overbooking of RHP efficiently by selecting protect paths which lead to the lowest spectrum utilization in the network for RHP enabled services. Current RHP solutions do not consider spectrum usage. This can lead to usage of extra spectrum, which could have otherwise been saved.
