Information-Centric Networking (ICN) proposals rethink the communication model around named data, in contrast with the host-centric transport view of TCP/IP. The content retrieval in ICN is natively receiver-driven, chunk-level based, multi-path forwarding and intrinsically coupled with in-network caching. To make the best use of in-network caching resources, NDN router should acquire the view of...
With the wide deployment of network facilities and the increasing requirement of network reliability, the disruptive event like natural disaster, power outage or malicious attack has become a non-negligible threat to the current communication network. Such disruptive event can simultaneously destroy all devices in a specific geographical area and affect many network based applications for a long time...
This paper proposes two lightpath-level active rerouting algorithms, namely, the least resources rerouting algorithm and the load balanced rerouting algorithm, in all-optical WDM networks with alternate routing and traffic grooming. The proposed algorithms consist of three major components to be determined: i) when the rerouting algorithm initiates, ii) which lightpath is rerouted, and iii) which...
As a newly rising topic in network multicast Held, application layer multicast is widely concerned. Analyze and compare technical proposal of application layer multicast protocols Narada, NICE and HMTP, etc. used by typical wide P2P streaming media service model, make an outlook on study prospect of P2P streaming media and summarize study status and its existing problems of P2P streaming media, which...
We investigate the problem of clustering on distributed data streams. In particular, we consider the k-median clustering on stream data arriving at distributed sites which communicate through a routing tree. Distributed clustering on high speed data streams is a challenging task due to limited communication capacity, storage space, and computing power at each site. In this paper, we propose a suite...
