Abstract
The present disclosure relates to implementing a Redundancy Box (“RedBox”) functionality in a software-defined network (“SDN”). In one embodiment, a configuration subsystem may identify at least one singly attached node (“SAN”) in the SDN and identify at least one dually attached node (“DAN”) in the SDN. The configuration subsystem may generate a first subset of a plurality of communication flows to implement RedBox functionality for communications between at least one SAN and at least one DAN
Claims20
A system to implement a Redundancy Box (“RedBox”) functionality in a software-defined network (“SDN”), comprising:
- a configuration subsystem to:
- identify at least one singly attached node (“SAN”) in the SDN;
- identify at least one dually attached node (“DAN”) in the SDN;
- generate a first subset of a plurality of communication flows to implement RedBox functionality by one of a plurality of network devices in the SDN and to convert traffic directed between the at least one SAN and the at least one DAN in the SDN;
- and
- generate a second subset of communication flows to implement a redundant protocol for traffic directed to the at least one DAN in the SDN sourced by a SAN and to convert traffic directed to the at least one DAN using a redundant protocol;
- and
- a communication interface to communicate the plurality of communication flows to the plurality of network devices in the SDN.
A method of implementing a Redundancy Box (“RedBox”) functionality in a software-defined network (SDN), comprising:
- identifying, using a configuration subsystem, at least one singly attached node (SAN) in the SDN;
- identifying, using the configuration subsystem, at least one dually attached node (DAN) in the SDN;
- generating, using the configuration subsystem, a first subset of a plurality of communication flows to implement RedBox functionality by one of a plurality of network devices in the SDN and in communication with the SAN;
- generating, using the configuration subsystem, a second subset of communication flows to implement a redundant protocol for traffic directed between the at least one DAN and the at least one SAN.
