Abstract

An apparatus and method for network routing is provided. Synchronized networks are disclosed which enable fast connection set up and release in a tiered hierarchy of circuit switched nodes. Nodes in the network can aggregate and disaggregate data according to a transform algorithm allowing for dynamic frame and frame segment sizing. Connections within the network can be organized by paired connections performing aggregation and disaggregation according to control vectors.

Claims

1. A method of routing network data, the method comprising:

receiving network data including data designating a destination address;

identifying a paired connection with an exit node corresponding to the destination address,

changing the identified paired connection from a virtual state to a real state;

assigning a bandwidth to the real state paired connection;

implicitly addressing the network data to generate an aggregated data stream of cellets containing the received network data, the aggregated data stream comprising at least one space/time frame including at least one cellet from the aggregated data stream of cellets, wherein a position of the at least one cellet in the at least one space/time frame is determined based on the identified paired connection, and wherein a size of the at least one cellet or a number of cellets included in the at least one space/time frame is determined based on the assigned bandwidth; and

transmitting the cellets over the real state paired connection.

2. The method of claim 1, wherein the virtual state paired connection stores connection parameters in a connection bandwidth register while assigning zero bandwidth to the connection.

3. The method of claim 1, wherein the assigned bandwidth of the real state connection pair is dynamically adjusted by changing the number of cellets in the at least one space/time frame of the aggregated data stream.

4. The method of claim 1, further comprising:

transmitting control vectors passed to an exit node including data indicative of disaggregating the implicitly addressed cellets, such that the disaggregation of the aggregated data stream is performed at the exit node.

5. The method of claim 1,

further comprising:

determining a period of the at least one space/time frame and/or the size of the at least one cellet based on a data rate of a trunk or link and a minimum required bandwidth for any packet flow on the trunk or link.

6. The method of claim 5, further comprising:

allocating a number of cellets per space/time frame to the packet flow based on a ratio of a required bandwidth of a first packet flow to the minimum required bandwidth for any packet flow on the trunk or link.

7. The method of claim 6, wherein the cellets allocated to the first packet flow are nearly uniformly spaced in a space/time domain.

8. The method of claim 7, wherein the variations in the required bandwidth of the first packet flow include zero bandwidth, and wherein allocation corresponding to zero bandwidth is zero cellet, and the zero-bandwidth connection is maintained in a virtual state.

9. The method of claim 1, further comprising:

determining a route for the connection from a plurality of routes based, at least in part, on route latencies.

10. The method of claim 1, wherein the control vector exists in a control plane physically and logically unreachable from a user port.

11. A system for performing network data routing, comprising:

an entry node associated with a packet source of a network, configured to;

receive network data including data designating a destination address;

identify a paired connection with an exit node corresponding to the destination address,

change the identified paired connection from a virtual state to a real state;

assign a bandwidth to the real state paired connection;

implicitly address the network data to generate an aggregated data stream of cellets containing the received network data, the aggregated data stream comprising at least one space/time frame including at least one cellet from the aggregated data stream of cellets, wherein a position of the at least one cellet in the at least one space/time frame is determined based on the identified paired connection, and wherein a size of the at least one cellet or a number of cellets included in the at least one space/time frame is determined based on the assigned bandwidth; and

transmit the cellets over the real state paired connection.

12. The system of claim 11, wherein the virtual state paired connection stores connection parameters in a connection bandwidth register while assigning zero bandwidth to the connection.

13. The system of claim 11, wherein the assigned bandwidth of the real state connection pair is dynamically adjusted by changing the number of cellets in the at least one space/time frame of the aggregated data stream.

14. The system of claim 11, wherein the entry node transmits control vectors passed to an exit node including data indicative of disaggregating the implicitly addressed cellets, such that the disaggregation of the aggregated data stream is performed at the exit node.

15. The system of claim 11,

wherein the entry node determines a period of the at least one space/time frame and/or the size of the at least one cellet based on a data rate of a trunk or link and a minimum required bandwidth for any packet flow on the trunk or link.

16. The system of claim 15, wherein the entry node allocates a number of cellets per space/time frame to the packet flow based on a ratio of a required bandwidth of a first packet flow to the minimum required bandwidth for any packet flow on the trunk or link.

17. The system of claim 16, wherein the cellets allocated to the first packet flow are nearly uniformly spaced in a space/time domain.

18. The system of claim 17, wherein the variations in the required bandwidth of the first packet flow include zero bandwidth, and wherein allocation corresponding to zero bandwidth is zero cellet, and the zero-bandwidth connection is maintained in a virtual state.

19. The system of claim 11, wherein the entry node determines a route for the connection from a plurality of routes based, at least in part, on route latencies.

20. The system of claim 11, wherein the control vector exists in a control plane physically and logically unreachable from a user port.
