ICN BASED DISTRIBUTED RESOURCE DIRECTORY FOR IOT RESOURCE DISCOVERY AND ROUTING

摘要

A method implemented in a network element (NE) configured to operate in an information centric network (ICN), the method comprising receiving, from a client via a receiver, a Resource Directory (RD) lookup message directed to a distributed RD database and comprising a lookupType field and an attribute value pair; converting the RD lookup message into an RD Lookup Forward (RDLF) comprising an RDLF lookupType field set to the lookupType field of the RD lookup message, an RDLF Time-To-Live (TTL) set to a largest number of hops that can be traversed in the ICN, and an RDLF attribute value pair set to the attribute value pair of the RD lookup message; and determining a forwarding interface list based on matching, to the attribute value pair, a routing entry from a Routing Table corresponding to the attribute value pair, wherein the Routing Table comprises routing information through the ICN to content mapped to a plurality of attribute value pairs.
