Abstract

Systems, computer program products, and methods are described herein for dynamic reconfiguration of network communications. An example system includes a first network pod including a first set of network ports, a second network pod including a second set of network ports, a set of network cores, and a first intermediate network switch. The first intermediate switch operatively couples the first network pod, the second network pod, and the set of network cores. The first intermediate network switch is configured to selectively establish full bisectional bandwidth data communication between a subset of the set of network cores, a subset of the first set of network ports, and a subset of the second set of network ports.

First claim

That which is claimed is:

1 . A system for dynamic reconfiguration of network communications, the system comprising:
a first network pod comprising a first set of network ports; a second network pod comprising a second set of network ports; a set of network cores; and a first intermediate network switch comprising a first optical switch configured to operatively couple the first network pod, the second network pod, and the set of network cores, wherein the first intermediate network switch comprising the first optical switch is configured to selectively establish full bisectional bandwidth data communication between a subset of the set of network cores, a subset of the first set of network ports, and a subset of the second set of network ports by: receiving a first stimulus to establish data communication between a first network port associated with the first network pod and a second network port associated with the second network pod using a subset of the network cores; responsive to the first stimulus, operatively coupling the first network port and the second network port using the first network pod, the second network pod, and the subset of the network cores; and disabling a remaining subset of network cores to reduce a power consumption of the system while maintaining full bisectional bandwidth data communication between the first network port and the second network port.

2 . The system of claim 1 , wherein the first intermediate network switch is further configured to:
receive a second stimulus to establish data communication between the first network pod and the second network pod; and responsive to the second stimulus, operatively couple the first set of network ports and the second set of network ports.

3 . The system of claim 2 , wherein the first intermediate network switch is further configured to:
responsive to the second stimulus, terminate a communication link between the first network pod, the second network pod, and the set of network cores; and operatively couple the first set of network ports and the second set of network ports.

4 . The system of claim 1 , further comprising:
a second intermediate network switch comprising a second optical switch operatively coupled to the first set of network ports, wherein the first set of network ports comprises a first set of input network ports and a first set of output network ports operatively coupled in a first network configuration, wherein the second intermediate network switch comprising the second optical switch is further configured to: receive a third stimulus to reconfigure the first network pod from the first network configuration to a second network configuration; and responsive to the third stimulus, operatively couple a subset of the first set of input network ports and a subset of the first set of output network ports in the second network configuration to establish full bisectional bandwidth data communication.

5 . The system of claim 4 , wherein the first set of input network ports are spine switches, and the first set of output network ports are leaf switches.

6 . The system of claim 4 , wherein the first set of input network ports are leaf switches, and the first set of output network ports are host terminals.

7 . The system of claim 4 , wherein the second network configuration is a mesh network configuration or a torus interconnect network configuration.

8 . The system of claim 4 , wherein the second intermediate network switch is further configured to physically isolate at least a portion the first set of network ports.

9 . An optical switch for allocating bandwidth for network communications, the optical switch operatively coupling a first network pod, a second network pod, and a set of network cores, wherein the optical switch is configured to:
receive a first stimulus to establish data communication between a first network port associated with the first network pod and a second network port associated with the second network pod using a subset of the network cores; responsive to the first stimulus, operatively couple the first network port and the second network port using the first network pod, the second network pod, and the subset of the network cores; and disable a remaining subset of the network cores in response to receiving the first stimulus so as to reduce a power consumption associated with the network communications while maintaining full bisectional bandwidth data communication between the first network port and the second network port.

10 . The optical switch of claim 9 , further configured to:
receive a second stimulus to establish data communication between the first network pod and the second network pod; and responsive to the second stimulus, operatively couple the first set of network ports and the second set of network ports.

11 . The optical switch of claim 10 , further configured to:
responsive to the second stimulus, terminate a communication link between the first network pod, the second network pod, and the set of network cores; and operatively couple the first set of network ports and the second set of network ports.

12 . The optical switch of claim 9 , wherein the first network pod comprises a first set of input network ports and a first set of output network ports operatively coupled in a first network configuration, wherein the optical switch is further configured to:
receive a third stimulus to reconfigure the first network pod from the first network configuration to a second network configuration; and responsive to the third stimulus, operatively couple a subset of the first set of input network ports and a subset of the first set of output network ports in the second network configuration.

13 . The optical switch of claim 12 , wherein the optical switch is further configured to physically isolate at least a portion the first set of network ports.

14 . A method for allocating bandwidth for network communications, the method comprising:
receiving a first stimulus to establish data communication between a first network port associated with a first network pod and a second network port associated with a second network pod using a subset of network cores; responsive to the first stimulus, operatively coupling, via a first intermediate network switch comprising a first optical switch, the first network port and the second network port using the first network pod, the second network pod, and the subset of the network cores; and disable a remaining subset of the network cores in response to receiving the first stimulus so as to reduce a power consumption associated with the network communications while maintaining full bisectional bandwidth data communication between the first network port and the second network port.

15 . The method of claim 14 , wherein the method further comprises:
receiving a second stimulus to establish data communication between the first network pod and the second network pod; and responsive to the second stimulus, operatively coupling the first set of network ports and the second set of network ports.

16 . The method according to claim 14 , further comprising:
receiving a third stimulus to reconfigure a first network pod from a first network configuration to a second network configuration; and responsive to the third stimulus, operatively coupling a subset of a first set of input network ports and a subset of a first set of output network ports in the second network configuration, wherein the first set of input network ports and the first set of output network ports are associated with the first net
