COMMUNICATION NETWORK, DEVICES AND METHODS FOR PROXIMITY BASED DISTRIBUTED CACHING OF SERVICE INFORMATION WITHIN SAID NETWORK

摘要

Communication networks devices and methods for proximity based distributed caching of service information within said network are disclosed. The network comprises service endpoint device (1402), client devices (1404), resource directory devices (1406), and border router devices (1408), in communication with each other. The methods for proximity based distributed caching of service information comprises: identifying (1502) RDs in a network; identifying (1504) service endpoints or clients in the network and assigning (1506) preferred RD to every service endpoint or client; registration (1508) of service endpoints with the service information to the preferred RD, the RD then backups the information on the BR; client always does the service lookup (service lookup from the client) (1510) from its preferred RD, if that RD cannot locally fulfill the lookup then it queries the BR for information, and based on the lookup patterns the RD decides to cache the service information i.e., proximity-based caching (1512).
