Router and methods using network addresses for virtualization
First Claim
1. A router for routing frames in a network, the router comprising:
- a first means for processing processor that performs a proxy process for a virtual member of the network, the proxy process responsive to a frame addressed in accordance with a first network address, the virtual member corresponding to at least a portion of a nonvirtual member of the network, the nonvirtual member responsive to frames addressed in accordance with a second network address; and
a second means for processing that performs a routing process that routes frames addressed in accordance with the first network address and of a first type to the proxy process;
that in response to receiving frames in accordance with the first network address and of a second type, provides a corresponding frame revised in accordance with the second network address; and
that routes the revised frames to the nonvirtual member in accordance with the second network address;
wherein the second means for processing comprises;
means for storing;
means for parsing;
a plurality of queues that receive data enqueued by the means for parsing; and
means for submitting that submits data from a queue of the plurality to the means for storing to provide a result;
wherein the second means for processing determines the second network address in accordance with the result;
wherein the means for storing provides a first result in accordance with first data submitted from the means for parsing, the first data comprising a flag; and
the means for storing provides the result in accordance with second data, the second data submitted from the second means for processing, in accordance with the flag; and
wherein the result comprises at least one of a resource identifier, a network address of a proxy, and logical unit number.

Abstract
A router for use in a network includes a scalable architecture and performs methods for implementing quality of service on a logical unit behind a network port; and for implementing storage virtualization. The architecture includes a managing processor, a supervising processor; and a plurality of routing processors coupled to a fabric. The managing processor has an in-band link to a routing processor. A routing processor receives a frame from the network, determines by parsing the frame, the protocol and logical unit number, and routes the frame to a queue according to a traffic class associated with the logical unit number in routing information prepared for the processors. An arbitration scheme empties the queue in accordance with a deficit round robin technique. If a routing processor detects the frame'"'"'s destination is a virtual entity, and so is part of a virtual transaction, the router conducts a nonvirtual transaction in concert with the virtual transaction. The nonvirtual transaction accomplishes the intent of the virtual transaction but operates on an actual network port, for example, a storage device.
