A network path scoring system is disclosed herein that scores quality of network paths to facilitate identification of poorly performing circuits for investigation. The scoring system builds a profile with packet loss data in relation to a load corresponding to a network path. The profile indicates the percentiles of packet loss at each bucket or bin of load based on the packet loss data. Using the profile for the network path, the scoring system calculates a capacity agnostic score based on a non-zero boundary in the profile across at least a subset of the load bins.

Capacity agnostic scoring of network path health based on packet loss

A network path scoring system is disclosed herein that scores quality of network paths to facilitate identification of poorly performing network paths or circuits for investigation. The scoring system builds a profile of additional latencies of a network path binned by circuit load based on historical latency data for the network path. The additional latencies are determined with respect to a base latency of the network path. The network path scoring system determines a weighted average of the additional latencies of a subset of the load bins and a weighted average of expected latencies of the subset of load bins, and a score is calculated with these weighted averages.

Network path health scoring based on load binned latency data

Various techniques for dynamic path selection and data flow forwarding are disclosed. For example, various systems, processes, and computer program products for dynamic path selection and data flow forwarding are disclosed for providing dynamic path selection and data flow forwarding that can facilitate preserving/enforcing symmetry in data flows as disclosed with respect to various embodiments.

Dynamic path selection and data flow forwarding

A method includes determining a network requirement for at least one application, dynamically determining a link suitable for data transmission in accordance with a policy based at least in part on a current network condition to meet the network requirement and routing one or more application network data flows associated with the at least one application over the link.

Methods and systems for business intent driven policy based network traffic characterization, monitoring and control

A method includes detecting a data flow and an associated originating interface on a network, determining a first link over which to forward the data flow, transmitting the data flow over the determined link, receiving a return data flow and moving a forward direction of the return data flow to a new path if the return data flow arrived via a link other than the first link, wherein all packets following a first packet on the flow are forwarded on the same path as the first packet.
