Method and apparatus for providing OC-n virtual bridge ports
A method and apparatus for intelligent packet forwarding utilizing virtual ports defined by a grouping of one or more STS-1s allocated to source and destination I/O devices (client) connected to an NxSTS-1 SONET network. A data flow path for transporting the client data is established from one virtual port at the source port to another virtual port at the destination port. The data flow path is established by notifying each of the ports of the data flow path and providing to the source port an address identifying the destination port and providing to the destination port an address identifying the source port.
1. A method for intelligent packet forwarding over a network, comprising:
providing a virtual ports comprising a grouping of one or more STS-1s is allocated to a source client and a destination client and an amount of bandwidth associated with the grouping;
assigning the grouping to a data flow path from a source port of the source client to a destination port of the destination client, wherein the assigning of the grouping is done through one of a network management system connected to the source client and the destination client and directly through the source client and the destination client;
establishing the data flow path for the grouping from the source port to the destination port, wherein the data flow path is established from a first virtual port at the source port to a second virtual port at the destination port; and
wherein the routing in the network of the grouping of one or more STS-1s is independent of the virtual ports.
2. A method according to claim 1 , further comprising notifying each of said source port and destination port of said data flow path, and providing to said source port an address identifying said destination port and providing to said destination port an address identifying said source port.
3. The method according to claim 1 wherein the network is a SONET network.
4. The method according to claim 1 , wherein the grouping of one or more STS-1s is connected to a network access device.
5. An apparatus for intelligent packet forwarding over a network, comprising:
a grouping device that provides virtual ports comprising a grouping of one or more STS-1s allocated to a source client and a destination client and an amount of bandwidth associated with the grouping;
an assignment device that assigns the grouping to a data flow path from a source port of the source client to a destination port of the destination client, wherein the assignment device assigns the grouping through one of a network management system connected to the source client and the destination client and directly through the source client and the destination client;
forwarding rules for transporting data on a data flow path extending from said source port to said destination port and notifying each of said ports of said data flow path, wherein the data flow path is established from a first virtual port at the source port to a second virtual port at the destination port; and
wherein the routing in the network of the grouping of one or more STS-1s is independent of the virtual ports.
6. The apparatus according to claim 5 , further comprising an address identifier for identifying and providing to said source port an address identifying said destination port and for identifying and providing to said destination port an address identifying said source port.
7. The apparatus according to claim 5 , wherein the network is a SONET network.
