Anycast Service Grooming Algorithm of Cloud Computing Based on Wireless Communication Network

In order to improve the energy efficiency of optical interconnection network between data centers, a hybrid path transmission energy-saving routing algorithm with service duration awareness is proposed for Anycast service. In order to reduce the number of new optical path and working components, single path transmission is preferred; If the traffic is blocked, the transmission energy consumption is minimized. In addition, the traffic grooming strategy based on spectrum reservation is introduced to reduce the cost of protecting bandwidth and optical transceiver. Simulation results show that: compared with the traditional energy-saving routing algorithm, the proposed algorithm can significantly reduce the network energy consumption, effectively avoid the excessive increase of traffic blocking rate, and achieve the balance of network energy consumption and performance.
