The default cache strategy of Content Centric Networking(CCN) is storing at each Content Router (CR) along the deliver path. It is high cache redundancy which causes the performance of CCN degradation. Hence, finding an efficient caching mechanisms is necessary in CCN. We agree that the single attribute can not to adapt to the complex network environment. the MAC considers hop count or distance, node...
There are some disadvantage in traditional "special line" networking, IP network, frame relay and the ATM network. A VPN networking project which based on MPLS is put forward in order to solve the problem. Then analyze the realization of MPLS VPN. The simulation principle, simulation process and simulation scenes are introduced by OPNET, get the results that MPLS VPN has lower delay and...
A method of video stream evaluation and test performance based on Ethernet-PON (passive optical network) was proposed. The IP-based video service or so called IPTV has emerged as the most promising network technology and its QoS (quality of service) has becoming a key concern in access network. The paper gives the performance evaluation of unicast and multicast video stream with different flux. Detailed...
To provide visual communication over enterprise leased line, the remote video surveillance system should be a suitable architecture to take the place of analog video model. The paper gives a reference design of remote digital video monitor system based on embedded system and dual core processors which can apply to IP-based video system. It has the merits of low cost and high quality for digital video...
