Abstract

Certain embodiments described herein are generally directed to interconnecting a plurality of local control planes (LCP) for state data exchange. In some embodiments, a first LCP receives the state data and a distribution list from a central control plane (CCP) node. The distribution list may comprise identifiers of LCPs to which the state data relates. In certain embodiments, the first LCP transmits an acknowledgment to the CCP node indicating receipt of the state data. In some embodiments, the first LCP identifies, according to a distribution pattern, one or more target LCPs of those identified in the distribution list. The distribution pattern may be based on information in the distribution list, information stored by the first LCP, or a combination of the two. In some embodiments, the first LCP may transmit the state data to the one or more target LCPs.

Dependent claims

A method for interconnecting a plurality of local control planes (LCPs) for state data exchange, comprising:

receiving, by a first LCP of the plurality of LCPs, from a central control plane (CCP) node, state data and a distribution list, wherein the distribution list comprises identifiers of a set of LCPs of the plurality of LCPs to which the state data relates;
transmitting, by the first LCP, an acknowledgment to the CCP node indicating that the first LCP has received the state data;
identifying, by the first LCP, and according to a distribution pattern, one or more target LCPs of the set of LCPs identified in the distribution list, wherein the distribution pattern is based on at least one of:
information included in the distribution list;
and
information stored by the first LCP;
transmitting, by the first LCP, the state data to the one or more target LCPs;
receiving, by each respective LCP of the one or more target LCPs, the state data from the first LCP;
transmitting, by each respective LCP of the one or more target LCPs, a respective acknowledgment to the CCP node indicating that the respective LCP has received the state data;
receiving, by the CCP node, the acknowledgment from the first LCP and the respective acknowledgment from each respective LCP of the one or more target LCPs;
and
identifying, by the CCP node, and based on the distribution list, any remaining LCPs of the set of LCPs identified in the distribution list that have not transmitted acknowledgements to the CCP node.

A non-transitory computer readable medium comprising instructions to be executed in a computer system, wherein the instructions when executed in the computer system, cause the computer system to perform a method for interconnecting a plurality of local control planes (LCP) for state data exchange, the method comprising:

receiving, by a first LCP of the plurality of LCPs, from a central control plane (CCP) node, state data and a distribution list, wherein the distribution list comprises identifiers of a set of LCPs of the plurality of LCPs to which the state data relates;
transmitting, by the first LCP, an acknowledgment to the CCP node indicating that the first LCP has received the state data;
identifying, by the first LCP, and according to a distribution pattern, one or more target LCPs of the set of LCPs identified in the distribution list, wherein the distribution pattern is based on at least one of:
information included in the distribution list;
and
information stored by the first LCP;
transmitting, by the first LCP, the state data to the one or more target LCPs;
receiving, by each respective LCP of the one or more target LCPs, the state data from the first LCP;
transmitting, by each respective LCP of the one or more target LCPs, a respective acknowledgment to the CCP node indicating that the respective LCP has received the state data;
receiving, by the CCP node, the acknowledgment from the first LCP and the respective acknowledgment from each respective LCP of the one or more target LCPs;
and
identifying, by the CCP node, and based on the distribution list, any remaining LCPs of the set of LCPs identified in the distribution list that have not transmitted acknowledgements to the CCP node.

A computer system, comprising:

one or more processors;
and a non-transitory computer-readable medium comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform a method for interconnecting a plurality of local control planes (LCP) for state data exchange, the method comprising:
receiving, by a first LCP of the plurality of LCPs, from a central control plane (CCP) node, state data and a distribution list, wherein the distribution list comprises identifiers of a set of LCPs of the plurality of LCPs to which the state data relates;
transmitting, by the first LCP, an acknowledgment to the CCP node indicating that the first LCP has received the state data;
identifying, by the first LCP, and according to a distribution pattern, one or more target LCPs of the set of LCPs identified in the distribution list, wherein the distribution pattern is based on at least one of:
information included in the distribution list;
and
information stored by the first LCP;
transmitting, by the first LCP, the state data to the one or more target LCPs;
receiving, by each respective LCP of the one or more target LCPs, the state data from the first LCP;
transmitting, by each respective LCP of the one or more target LCPs, a respective acknowledgment to the CCP node indicating that the respective LCP has received the state data;
receiving, by the CCP node, the acknowledgment from the first LCP and the respective acknowledgment from each respective LCP of the one or more target LCPs;
and
identifying, by the CCP node, and based on the distribution list, any remaining LCPs of the set of LCPs identified in the distribution list that have not transmitted acknowledgements to the CCP node.
