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.
This paper defines network function and information flow to process the calls between Wibro and mobile phone, Wibro and wired phone which is resulted from number portability of Wibro VoIP by using NPSS. This paper also defines new number portability system, network function, information interface packet and system function according to the requirement of number portability.
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...
Carrier networks are gradually adopting a network model that consists of MPLS-capable routers and OXCs interconnected by high bandwidth WDM links for transporting IP and Ethernet traffic. A control plane can be used to deliver dynamic circuit provisioning in the transport layer, as well as bandwidth provisioning and traffic engineering in higher layers. Globalization drives the quest for end-to-end...
Most network operators have considered reducing Label Switched Routers (LSR) label spaces (i.e. the number of labels that can be used) as a means of simplifying management of underlaying Virtual Private Networks (VPNs) and, hence, reducing operational expenditure (OPEX). This letter discusses the problem of reducing the label spaces in Multiprotocol Label Switched (MPLS) networks using label merging...
Many today TCP modules are derived from the BSD implementation which handles packet loss as signal of congestion. While in the wireless networks, the non-congestive packet losses can be frequent and shall be handled differently. In this paper we apply the visualized IP-based network simulator (VINS) to study the differences between packet losses due to congestion and that due to link disruption, and...
