: MCDM-Based Interest Forwarding and Cooperative Data Caching for Named Data Networking

Algorithm 2

The proposed cooperative data caching.

	, , , , , and :
	Defined before;
	: The Pending Interest Table at ;
	: The set of incoming interfaces associated with data in the Pending Interest Table at . Here, is the set of incoming interfaces that the Interest packets have been received from;
	: The Content Store at ;
	: The Forwarding Information Base at ;
	: The number of hops between the data producer and ;
	: the number of hops between the boarder router and ;
When receives a Data packet :
