| Summary: | A cache allocation policy(CA)of service contents along delivery paths was proposed for the smart collabora-tive network.CA allocates on-path caches to service contents based on their popularity,expecting to fully and efficiently utilize the cache resource along the delivery path and further improving the network performance.The performance of proposed policy CA was evaluated under a 5-layer tree topology and a 279-node real network topology.The results show that CA outperforms others in terms of tested performance indexes.Compared with LCE(leave copy everywhere)used by named data networking(NDN),CA reduces the distance that users fetch service contents over 20%. |
