IPv6 is the key technology of the next generation Internet, this paper analyses the strategies for managing the transition from IPv4 to IPv6, designs the campus network transition scheme based on IPv6 automatic tunnel technology, and verifies the feasibility that IPv4 network can access IPv6 network through IPv6 automatic tunnel technology by the experiment.
The deployment of the next-generation Internet protocol, IPv6, has progressed rather slowly. Although some commercial products have been incorporated with parts of functions of IPv6, it is still difficult to have a revolution from IPv4 to IPv6 at one night. Since the current users on line must be cared, the migration from IPv4 to IPv6 must begin from integrating both IPv4 and IPv6 networks. In this...
Wireless Mesh Networks (WMNs) provide a cost-effective way of deploying a network and providing broadband Internet access. In WMNs a subset of nodes called gateways provide connectivity to the wired infrastructure (typically the Internet). Because traffic volume of WMNs is expected to be high, and due to limited wireless link capacity, gateways are likely to become a potential bottleneck. In this...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
