Abstract

A method and system for managing an interconnect fabric (110) that connects nodes. A network manager (115) manages an interconnect fabric or network of routing devices (e.g., interconnect fabric modules, switches, or routers) to allow source nodes (105) to transmit data to destination nodes. The network manager (115) receives registration requests from source nodes to send data to destination nodes, configures the routing devices of the network to establish a path from each source node to its destination node, and provides a virtual address to each source node. The virtual address identifies a path from the source node to the destination node. The source node sends the data to its destination node by providing the data along with the virtual address to a routing device of the network. Upon receiving the data and the virtual address, a source-side port of each routing device in the path uses the virtual address to identify a destination-side port through which the data and the virtual address are to be transmitted.

Claims

AMENDED CLAIMS[received by the International Bureau on 18 November 2002 (1 S.11.02); original claims 1 and 15 amended; remaining claims unchanged (2 pages)]
1. A method in a network manager for identifying topology of a network, the network including a plurality of routing devices, each routing device having ports, the method comprising: retrieving from each of the routing devices an indication of which of the ports of the routing device are connected to another port; and for each routing device, for each port of the routing device that is connected to another port, sending to that routing device a query message to be forwarded through that port to the other port; and receiving from that routing device a response from the other port identifying the routing device of the other port and the other port within the identified routing device.
2. The method of claim 1 including generating a mapping from each routing device and port to device and port to which it is connected to indicate the topology of the network.
3. The method of claim 1 wherein a routing device is a switch.
4. The method of claim 1 wherein a routing device is an interconnect fabric module.
5. The method of claim 1 wherein the routing devices use virtual addresses to route frames.
6. The method of claim 1 wherein the identification of the topology is performed by a network manager.
7. The method of claim 6 wherein the network manager is distributed to the routing devices.
37
8. The method of claim 1 wherein the query message is sent via out-of-band communications.
9. The method of claim 1 wherein the query message is sent via in-band communications.
10. The method of claim 1 wherein the routing devices of the network are identified via the received responses.
11. The method of claim 10 wherein when a routing device is identified, retrieving an indication of which of the ports of the routing device are connected to another port.
12. The method of claim 1 wherein the retrieving of an indication of which of the ports of the routing devices are connected to another port includes sending a request to the routing device.
13. The method of claim 1 wherein the retrieving of an indication of which ports of the routing devices are connected to another port includes receiving a message from the routing device.
14. The method of claim 1 wherein each routing device determines which of its ports are connected to another port and the retrieving of an indication of which of the ports of the routing devices are connected to another port includes transmitting the determined information to a network manager.
15. A network manager for identifying topology of a network, the network including a plurality of routing devices, each routing device having ports, comprising: a component that retrieves indications of which of the ports of the routing devices are connected to another port; and a component that sends to the routing devices query messages to be forwarded through each port that is indicated as connected to another port to the other port and that receives from the routing devices responses from the other ports identifying the other devices and the other ports.
