A method for processing messages comprises: a first device sending a neighbor solicitation message to a second device, and then creating information of the second device based on a neighbor advertisement message replied by the second device; the first device sending a detection request message to the second device based on the created information of the second device, and determining whether a detection reply message sent by the second device is received in a period of time, and if it is not received, then the first device deleting the created information of the second device. Accordingly, a network device is provided comprising a neighbor solicitation message sending module, a neighbor advertisement message receiving module, an information creating module, a detection request message sending module and a detection reply message receiving module. Additionally, a method for processing messages and a network device are provided. The processing of the neighbor advertisement message by the methods and network devices decreases effects of the neighbor advertisement message with a false link layer address.

The present invention is directed to a method of and a system that monitors a network resource of a network and an application performance. The method categorizes a first subset of network traffic into trusted, known to be bad, and suspect categories. The method determines an action for a second subset of traffic based on the categorizing. Some embodiments provide a system for an adaptive networking having a first device and traffic that has a first subset and a second subset. The system also includes a first resource and a second resource for the transmission of the traffic. The first device receives the traffic and categorizes the traffic into the first and second subsets. The first device assigns the first subset to the first resource. Some embodiments provide a categorization module that categorizes incoming traffic, and a resource assignment module that assigns the categorized traffic for a particular resource. A traffic category for the device includes suspect traffic.

The present invention is directed to a system for and a method of selecting a combination of resources for transmitting data from a remote site to a destination site. The method comprises generating a list of combinations of resources at a regional site and transmitting the list to the remote site. Data is transmitted from the remote site to the regional site using each combination of resources and statistics for each transmission are stored. Metrics, based on the application at hand, are computed for each set of statistics corresponding to each transmission, and a preferred combination of resources is selected at the regional site based on the metrics. The regional site then transmits to the remote site information corresponding to the preferred combination of resources. The remote site is then configured to transmit data to the destination site using the selected combination of resources. Resources include links with a specified bandwidth, VPN and GRE tunnels, and routers configured to perform MPLS switching, type-of-service routing, and source routing.

Summary The present invention accomplishes an overlay transceiver apparatus (100), comprising a receiver module (110) for receiving a data packet (115), having a routing portion (116) and a payload portion (117) comprising underlay payload data (118). The overlay transceiver apparatus further (100) comprising a packet interpreter (120) for interpreting the received data packet (115) to find out information on an underlay data source (125) from the routing portion (116) of the received data packet (115) and on the underlay payload data (118) from the payload portion (117) of the received data packet (115), the underlay payload data (118) having information on an overlay data source (126) and on an overlay data destination (127); and for interpreting the underlay payload data (118) to find out the information on the overlay data source (126) and on the overlay data destination (127). Furthermore, the transceiver apparatus (100) comprises a controller module (130) for generating an acknowledgement data packet (135), comprising information on the underlay data source (125) in the routing portion (116) and an overlay acknowledgement (136) in the payload portion (117) of the acknowledgement data packet (135), and for generating a forward data packet (137) with a routing portion (116) and a payload portion (117), comprising information on the overlay transceiver apparatus identity (138) and on an underlay data destination (139) in the routing portion (116); and the underlay payload data (118) in the payload portion (117), the underlay payload data (118) having information on the overlay data source (126) and on the overlay data destination (127). Moreover the transceiver apparatus comprises a transmitter module (140) for transmitting the acknowledgement data packet (135) and the forward data packet (137).

A method and apparatus for LDP-IGP synchronization for broadcast networks. In one embodiment of the invention, responsive to a network element bringing up an adjacency with a Designated Router of the broadcast network on a broadcast interface, that network element advertises in its Link State Advertisement (LSA) a peer-to-peer (P2P) adjacency to each member of the broadcast network that has bidirectional IGP communication with the network element instead of advertising a pseudo-node adjacency to the pseudo-node of the broadcast network. Each P2P adjacency includes a high cost to discourage use of those links for transit traffic. After LDP becomes operational with ail neighbors on the broadcast interface, the network element advertises the pseudo-node adjacency instead of the P2P adjacencies. Accordingly, transit traffic is avoided through that network element until LDP is operational with all neighbors on the broadcast interface.
