20080205271 | VIRTUAL CONNECTION ROUTE SELECTION APPARATUS AND TECHNIQUES - Virtual connection route selection apparatus and techniques are disclosed. At a communication traffic routing apparatus, metric information associated with multiple different routes for a virtual connection, such as a PseudoWire, toward a destination is collected. The metric information may be collected from one or more remote route computation elements capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, or during actual establishment of the virtual connections, for example. An initial or re-optimized route for a virtual connection can then be selected at the routing apparatus based on the collected metric information. In some embodiments, although the virtual connection routes are paths computed by Path Computation Elements (PCEs), actual path selection decisions are distributed to routers. | 08-28-2008 |
20080225864 | COMMUNICATION NETWORK ROUTING APPARATUS AND TECHNIQUES USING LOGICAL COMMUNICATION LINKS - Communication network routing apparatus and techniques using logical communication links are disclosed. A routing apparatus identifies a logical communication link that it is capable of being used to establish a virtual connection with another routing apparatus within a virtual connection operational domain, which includes multiple sub-domains, of an underlying communication system. A destination that is associated with the routing apparatus and is reachable through the virtual connection is also identified. Information that is indicative of the identified logical communication link and of the identified destination is provided for distribution from a sub-domain of the routing apparatus in the virtual connection operational domain to another sub-domain within the virtual connection operational domain. This distribution of information enables a routing apparatus in one sub-domain to dynamically route a virtual connection toward a destination in a different sub-domain. Data structures for distributing the information are also disclosed. | 09-18-2008 |
20080279110 | Method and system for verifying connectivity of multi-segment pseudo-wires - A method for testing connectivity of a multi-segment pseudo-wire (“MS-PW”) in a network, the method comprising: sending an echo request message from a first provider edge (“PE”) device to a second provider edge (“PE”) device for a section of the multi-segment pseudo-wire (“MS-PW”) between the first provider edge (“PE”) device and the second provider edge (“PE”) device; the echo request message being identified as such by a control word contained therein; an inner label of the echo request message having a time-to-live (“TTL”) value set to a number of segments in the section; the time-to-live (“TTL”) value for determining whether the control word is to be inspected as it traverses the section; upon the echo request message arriving at the second provider edge (“PE”) device, the second provider edge (“PE”) device recognizing the echo request message as such by inspecting the control word contained therein; and, receiving an echo reply message from the second provider edge (“PE”) device in response to the echo request message, the echo reply message confirming connectivity of the section. | 11-13-2008 |
20100309915 | VIRTUAL LEASED LINE ADDRESS RESOLUTION PROTOCOL CACHE FOR CUSTOMER EDGE INTERNET PROTOCOL ADDRESSES - Various exemplary embodiments relate to a provider edge node and a method performed on the node including one or more of the following: storing, in a cache on the node, an association between an Internet Protocol (IP) address of the customer edge device and a Media Access Control (MAC) address of the customer edge device; storing, in a backup memory in the node, a copy of the last-known IP address of the customer edge device; removing the stored association from the cache in response to a cache-clearing event, while maintaining the copy of the last-known IP address in the backup memory; sending an address discovery message, the address discovery message requesting an updated MAC address corresponding to the last-known IP address maintained in the backup memory; and updating the cache to reflect the updated MAC address upon receipt of an additional address update message from the customer edge device. | 12-09-2010 |
