    摘要： The system provides an IP network card that comprises a redundancy configuration register; an interface; and redundancy mapping logic. The redundancy configuration register stores card configuration data. The interface receives slot active signals from other cards. The redundancy mapping logic is communicatively coupled to the register and interface. The logic maps a packet to a slot having an active card based on the data in the register, an address in the packet, and received slot active signals.

    摘要： A router and routing protocol redundancy are disclosed to reduce service outage or degradation for a network device and thus to increase service availability on a network due to software and hardware failures of the network device. A network device such as router includes a redundancy platform having an active controller system and a standby controller system. A routing protocol state change is received or generated by the active controller system. The received or generated routing protocol state change is replicated to the standby controller system. By replicating the routing protocol state change, the standby controller system can maintain the routing protocol sessions for the network device if a failure occurs in the active controller system. Furthermore, the routing protocol states are maintained in realtime to handle the dynamic changes created by routing protocols.

    摘要： The present invention establishes a circuit emulation service (CES) over an internet protocol (IP) network based on properties of the IP network. The CES emulates a circuit from a local interworking function to a remote interworking function. Data that is received at a constant bit rate at the local interworking function is encapsulated into a number of IP packets configured according to the CES. The IP packets are transported from the local interworking function to the remote interworking function according to the CES. In one embodiment, each IP packet also includes data segments for simultaneously encapsulating multiple constant bit rate circuits. In another embodiment, each data segment includes a separate CES circuit header.

    摘要： This invention provides compositions and methods for HCV typing, e.g., genotyping and/or subtyping. The compositions and methods of the invention can be used to assign an HCV isolate to one of at least five HCV types (for example, selected from types 1, 2, 3, 4, 5 or 6), or to one of at least five subtypes (for example, subtypes 1a/b/c, 2a/c, 2b, 3a, 4a, 5a or 6a). These methods integrate the hybridization data from a plurality of HCV typing probes in a multidimensional analysis to make an HCV type assignment for an HCV in an experimental sample. The invention also provides related compositions, including, for example, the HCV typing probes and HCV typing diagnostic kits.
