A method and device for communicating information resources between subscriber end stations and nodes belonging to different network domains is described. The device instantiates different virtual network machines for different network domains using separate independently administrable network databases. Each of the administrable chores of the separate independently administrable network databases includes the assignment of access control and the configuration of the policies for those network databases. The policies include traffic filtering policies to indicate what kind of information payloads can be carried, traffic and route filtering policies to indicate what paths through the network will be used for each payload carried. Each of the network domains includes one of the different virtual network machines and each of the different network domains is virtually isolated from other network domains.

Methods and apparatus for Fibre Channel interconnection is provided between a plurality of private loop devices through a Fibre Channel private loop device interconnect system. In the preferred embodiments, the Fibre Channel private loop device interconnect system is a fabric or an intelligent bridging hub. In one aspect of this invention, a Fibre Channel private loop device is connected to two or more Arbitrated Loops containing, or adapted to contain, one or more private loop devices. Preferably, the interconnect system includes a routing filter to filter incoming Arbitrated Loop physical addresses (ALPAs) to determine which Fibre Channel frames must attempt to be routed through the fabric. Numerous topologies of interconnect systems may be achieved. In another aspect of this invention, a method is provided for implementing a logical loop of private loop devices by segmenting the logical loop into a plurality of sets, assigning each set to a physical Arbitrated Loop and connecting the Arbitrated Loops to a Fibre Channel private loop device interconnect system. Additional methods are provided for restricting attached devices to Arbitrated Loop physical addresses within certain ranges. Additionally, methods are provided for resetting hosts, the method generally comprising the steps of detecting the addition of a storage device to a first Arbitrated Loop, and thereafter, resetting the Arbitrated Loop or loops on which a host or hosts reside on second Arbitrated Loop. Methods for operation with use of SCSI initiators generate a link service reject when no address match is found, or when an address match is found, but where no device with the destination ALPA exists on the Arbitrated Loop corresponding to the destination.

The invention relates to an IVR intelligent emergency disposal method based on 95598 large telephone traffic. The method includes intelligent telephone traffic routing filtering and an intelligent robot voice service. The intelligent telephone traffic routing filtering comprises region telephone traffic early warning, the IVR filtering traffic function and short message sending. The intelligent robot voice service is entered when telephone traffic is busy and is divided into service intelligent processing and online intelligent analysis. By means of the IVR intelligent emergency disposal method, effective filtering of manual requests in the peak telephone traffic region is achieved through the intelligent telephone traffic routing, and effective shunt of the manpower service is achieved through voice access of an intelligent robot; the intelligent telephone traffic routing filtering and the intelligent robot voice service are combined organically, and the center emergency disposal technology and means reach a new step through the different working modes.

A method, apparatus and system for propagating QoS policies, wherein the method comprises: generating first information according to a BGP route of a first network device received from an AS, the first information comprising one or more of an AS number list and a community list; according to the first information, generating a first QoS policy corresponding to the first information, wherein the first QoS policy comprises a route filter action; and sending the first information and the first QoS policy to the first network device. Thus, it is not required to change in advance the QoS policies separately for a plurality of receiving terminals, eliminating the need to plan route classification rules as well as the need to match a QoS local identifier and stream behavior name at the receiving terminal, simplifying QPPB configuration and reducing maintenance issues.
