    摘要: An apparatus and method for traversing a network address translation/firewall device to maintain a registration between first and second devices separated by the firewall device are provided. In one example, the method includes intercepting a registration message from the first device to the second device. A determination is made based on a first timeout period defined by the second device as to whether it is time to renew the first device's registration. If it is time to renew the first device's registration, the registration message is forwarded to the second device. A response message that includes the first timeout period is intercepted, and the first timeout period is replaced with a second timeout period based on a binding lifetime of the firewall device before forwarding the response message to the first device.

    摘要: A method and system are described for resolving problems created by implementing multiple networks using private IP addresses and layer two tunneling protocols is described. A network processing system is operable to map flows from private IP addresses and ports on layer two tunneling protocol networks to public IP addresses and ports using the private IP addresses and ports and identifiers for the layer two tunneling protocol network. The network processing system uses its own public IP addresses and ports to anchor the traffic from the private network and performs the required mapping to pass traffic between the public and private networks.

    摘要: A method and apparatus is described that allow the creation of virtual routing domains in an IP network. These virtual routing domains allow individual networks to be configures so that it appears that its routing domain covers the entire IP address space. A network processing system is used to implement the virtual routing domains and to allow network traffic to cross the individual routing domains. The network processing system is able to use application layer information to allow the crossing of virtual routing domain boundaries. By examining application layer information the network processing system is able to look up customer/user information and use that information to determine destination virtual routing domains and route otherwise unroutable addresses between domains.

    摘要: A method of forming a variable pattern across a wafer using a reticle forms a plurality of first patterns on the wafer. The first pattern is repeated across the wafer and each first pattern has a first readable element. The method also forms a plurality of second patterns on the wafer. The second patterns is repeated across the wafer and each second pattern has a second readable element. The second patterns are positioned relative to the first patterns by aligning a first second pattern relative to one portion of a corresponding first pattern and then incrementally misaligning each successive second pattern in a row or a column relative to its corresponding first pattern. Thus, each corresponding first readable element and second readable element form a corresponding variable pattern.
