Abstract

Systems and methods for interoperating between networks. A first network may be configured to operate according to a first real time network protocol and each of one or more second networks may be configured to operate according to respective second real time traffic protocols. A mapping may specify data routing between a plurality of ports and the routing may maintain real time behavior between the first network and the one or more second networks. Additionally, routing information may be inserted in packets routed from the one or more second networks to the first network and removed from packets routed from the first network to the one or more second networks. The packets may be routed, based on the mapping, 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.

Claims20

Dependent claims

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.
