With the development of the network technology, PIM-SMv2 protocol acted as a feasible telecommunication technology, gains wide application and development. This paper discusses the performing principles of PIM-SMv2 protocol in detail, describes how PIM-SMv2 protocol building unidirectional share trees rooted at a Rendezvous Point per group. This paper presented the realization project of IPv6 multicast...
Ethernet passive optical network is an emerging high-speed access network that can provide high bandwidth for TV service. However, traditional digital TV service based on digital video broadcasting standard broadcasts its data stream to end-users, which will add enormous burden to server and waste valuable bandwidth. To carry digital TV data stream efficiently, in this paper, we propose a novel architecture...
The design and development of future ground-space integrated networks is one of the hot issues in space technology nowadays because of the long-link delay, high bit-error-rate, asymmetric bandwidth, intermittent links compare with the terrestrial networks. The focus of this paper is to design topology for this hybrid networks with space segments, select appropriate protocols for it and analyze its...
Space wideband information network technology is one of the hot technologies in studying of space technology, there are many difficult technologies need to be solved, for example, technologies of the connection and communication between space and ground heterogeneous network, algorithm of mobile routing, etc. The paper does research on these problems based on IP technology of the ground network and...
