A Network Monitoring Tool for CCN

摘要

Recent discussions on the revolutionary Future Internet architecture have led to Content-Centric Networking (CCN) that puts emphasis on contents for the efficient information delivery. Since CCNx has been released as an early stage prototype of CCN, many projects are being developed on CCNx. However, a network monitoring function for CCN nodes or faces has not been implemented. In this paper, we propose a simple network monitoring method based on IETF IPFIX and SNMP for CCN. From IPFIX, we could easily find the detailed information on contents delivered in interest or data packets in the format of flows, while retrieving information on the CCN node and its tables in SNMP. Through our monitoring scheme, we could clearly diagnose the current status of CCN nodes and their data such as Content Stores, Pending Interest Table (PIT), and Forwarding Information Base (FIB).
