Systems and methods for network interoperability

1. A system for interoperating between a first network and one or more second networks, the system comprising:

a plurality of ports, comprising:

at least one port coupled to the first network, wherein the first network is configured to operate according to a first real time network protocol; and

one or more ports coupled respectively to the one or more second networks, wherein each of the one or more second networks are configured to operate according to respective second real time traffic protocols, wherein the first real time network protocol is not compatible with the respective second real time traffic protocols; and

a switch coupled to the plurality of ports, wherein the switch is configured with a mapping that specifies data routing between the plurality of ports, wherein the switch is configured to:

route packets between the first network and the one or more second networks based on the mapping, thereby maintaining real time behavior between the first network and the one or more second networks;

insert routing information in packets routed from the one or more second networks to the first network;

remove routing information from packets routed from the first network to the one or more second networks; and

route, based on the mapping, packets to distinct queues for the first network and the one or more second networks for processing by an application executing on at least one device.

9. A method for interoperating between a first network and one or more second networks, the method comprising:

routing packets between the first network and the one or more second networks via a plurality of ports based on a mapping, wherein the first network is configured to operate according to a first real time network protocol, wherein each of the one or more second networks are configured to operate according to respective second real time traffic protocols, wherein the mapping specifies data routing between the plurality of ports, and wherein said routing maintains real time behavior between the first network and the one or more second networks;

inserting routing information in packets routed from the one or more second networks to the first network;

removing routing information from packets routed from the first network to the one or more second networks; and

routing, based on the mapping, packets to distinct queues for the first network and the one or more second networks for processing by an application executing on at least one device.

10. The method of claim 9 ,

wherein the distinct queues comprise first queue pairs associated with traffic on the first network and one or more second queue pairs associated with traffic on the one or more second networks, wherein the method further comprises:

time stamping ingress and egress of packets to/from the first queue pairs and the one or more second queue pairs, wherein the application correlates clock synchronization information of the first network and one or more second time networks based on the time stamps.

11. The method of claim 9 ,

wherein the plurality of ports are comprised in a network interface controller.

12. The method of claim 9 ,

wherein the routing information comprises a virtual local area network (VLAN) tag.

13. The method of claim 12 ,

wherein the first network is associated with a first VLAN tag, wherein each of the one or more second networks is associated with a respective second VLAN tag.

14. A non-transitory computer readable memory medium storing program instructions executable by a processor to:

route packets between a first network and one or more second networks via a plurality of ports based on a mapping, wherein the first network is configured to operate according to a first real time network protocol, wherein each of the one or more second networks are configured to operate according to respective second real time traffic protocols, wherein the mapping specifies data routing between the plurality of ports, and wherein said routing maintains real time behavior between the first network and the one or more second networks;

insert routing information in packets routed from the one or more second networks to the first network;

remove routing information from packets routed from the first network to the one or more second networks; and

route, based on the mapping, packets to distinct queues for the first network and the one or more second networks for processing by an application executing on at least one device.

15. The non-transitory computer readable memory medium of claim 14 ,

wherein the distinct queues comprise first queue pairs associated with traffic on the first network and one or more second queue pairs associated with traffic on the one or more second networks, wherein the program instructions are further executable to:

time stamp ingress and egress of packets to/from the first queue pairs and the one or more second queue pairs, wherein the application correlates clock synchronization information of the first network and one or more second time networks based on the time stamps.
