| 摘要： |
We show that an aggregated Interest in Named Data Networking (NDN) may fail to retrieve desired data as the Interest sent upstream in advance is recognized as a duplicate one due to its multipath forwarding and dropped by an upstream node. Furthermore, we in- troduce NDRUDAF, a mechanism based on negative acknowledgement for the router that aggregates the In- terests to detect such unanticipated data access failure and assist the requester whose Interest is aggregated fast recovering from the failure. We qualitatively an- alyze the performance of the NDN with our proposal NDRUDAF and compare its performance with that of the present NDN. NDRUDAF improves the system per- formance in case of the unanticipated data access failure in terms of data access delay and network resource uti- lization e ciency at routers. |
