Abstract

The present disclosure provides a health checkup tool that tracks the status of each service (e.g., Subnetwork Connections (SNCs), Label Switched Paths (LSPs), flows, etc.) in control plane and/or Software Defined Networking (SDN) networks. The status can be maintained as Performance Monitoring (PM) counters such as in 15 min. and 24 hour intervals. The health checkup tool is different from current PM counters as it has different attributes, such as Mesh/Meshed-Failed/Switched/Preempted/ Preempted-Failed, etc. The health checkup tool can keep "Counter level statistics" and "Route level statistics." Networks can have significant complexity with hundreds of nodes and thousands of services. Very frequently, services in the network change their routes due to Mesh, Manual initiated commands, Reversions, preemption, etc. Mesh can be due to fiber cuts, hardware failure in networks or SNCIC (due to path defects). Manual initiated commands can be Manual Switch to Protect, Revert, Regroom, etc. Reversions can occur after recovery and timer expiration. Preemption can occur based on other services requiring resources. Collectively, these network changes can be successful, but also can fail for network or configuration issues, and the health checkup tool provides an efficient view for addressing any issues.

HEALTH CHECKUP TOOL FOR SERVICES IN A NETWORK

ABSTRACT

The present disclosure provides a health checkup tool that tracks the status of each service (e.g., Subnetwork Connections (SNCs), Label Switched Paths (LSPs), flows, etc.) in control plane and/or Software Defined Networking (SDN) networks.  The status can be maintained as Performance Monitoring (PM) counters such as in 15 min. and 24 hour intervals.  The health checkup tool is different from current PM counters as it has different attributes, such as Mesh/Meshed-Failed/Switched/Preempted/ Preempted-Failed, etc.  The health checkup tool can keep “Counter level statistics” and “Route level statistics.”  Networks can have significant complexity with hundreds of nodes and thousands of services.  Very frequently, services in the network change their routes due to Mesh, Manual initiated commands, Reversions, preemption, etc.   Mesh can be due to fiber cuts, hardware failure in networks or SNCIC (due to path defects).  Manual initiated commands can be Manual Switch to Protect, Revert, Regroom, etc.  Reversions can occur after recovery and timer expiration.  Preemption can occur based on other services requiring resources.  Collectively, these network changes can be successful, but also can fail for network or configuration issues, and the health checkup tool provides an efficient view for addressing any issues.

DETAILED DESCRIPTION

Again, in various exemplary embodiments, the present disclosure provides a health checkup tool that tracks the status of each service (e.g., Subnetwork Connections (SNCs), Label Switched Paths (LSPs), flows, etc.) in control plane and/or Software Defined Networking (SDN) networks.  The status can be maintained as Performance Monitoring (PM) counters such as in 15 min. and 24 hour intervals.  The health checkup tool is different from current PM counters as it has different attributes, such as Mesh/Meshed-Failed/Switched/Preempted/ Preempted-Failed, etc.  The health checkup tool can keep “Counter level statistics” and “Route level statistics.”  Networks can have significant complexity with hundreds of nodes and thousands of services.  Very frequently, services in the network change their routes due to Mesh, Manual initiated commands, Reversions, preemption, etc.   Mesh can be due to fiber cuts, hardware failure in networks or SNCIC (due to path defects).  Manual initiated commands can be Manual Switch to Protect, Revert, Regroom, etc.  Reversions can occur after recovery and timer expiration.  Preemption can occur based on other services requiring resources.  Collectively, these network changes can be successful, but also can fail for network or configuration issues, and the health checkup tool provides an efficient view for addressing any issues.
