摘要： The present invention provides a method for network service selection and authentication in an IPv6 access network, a scheme for stateless auto-configuration and devices thereof. A NSP Information option containing the IPv6 address of a NSP edge router and a NSP name is defined in RA messages. A NSSA Information option is defined in RS option fields. The present invention enables IPv6 stateless auto-configuration in an access network. The new NSP Information option, the way of “one time authentication per subscriber network per NSP” and the use of IPv6 routing header promote the efficiency of IPv6 stateless auto-configuration and reduce the NSP selection and authentication traffic. The present invention provides an efficient solution for network service selection and authentication without introducing any other message exchange between terminals and access nodes. In short, the scheme of network service selection and authentication according to the present invention is piggybacked on RS/RA messages, which is very simple.

摘要： One embodiment of the present invention provides a system that guarantees a stated failure-recovery time in an optical wavelength-division multiplexing (WDM) network. The system operates by first receiving a request at an ingress node of the WDM network to establish a connection from a source to a destination through the WDM network, wherein the request includes the stated failure-recovery time. The system then calculates a chain of restorable cycles within the WDM network between the ingress node for the source and an egress node for the destination, wherein each cycle in the chain of restorable cycles can guarantee the stated failure-recovery time. Finally, the system selects a section of each restorable cycle to be a primary path between the source and the destination through the restorable cycle.

摘要： One embodiment of the present invention provides a system that provides a guaranteed level of availability in a communication network. During operation, the system receives a connection request that includes a specified reliability. Next, the system determines multiple candidate routes through a network to satisfy the connection request, wherein each of these candidate routes passes through a set of links that form a path through the network. The system then examines the candidate routes to identify a route that meets the specified reliability. The system only accepts the connection request if a route that meets the specified reliability is found.
