Method and system for co-operative on-path and off-path caching policy for information centric networks

摘要: A method and a system is disclosed herein for co-operative on-path and off-path caching policy for information centric networks (ICN). In an embodiment, a computer implemented method and system is provided for cooperative on-path and off-path caching policy for information centric networks in which the edge routers or on-path routers optimally store the requested ICN contents and are supported by a strategically placed central off-path cache router for additional level of caching. A heuristic mechanism has also been provided to offload and to optimally store the contents from the on-path routers to off-path central cache router. The present scheme optimally stores the requested ICN contents either in the on-path edge routers or in strategically located off-path central cache router. The present scheme also ensures optimal formulation resulting in reduced cache duplication, delay and network usage.
