Logical link redundant paths

A computing device comprising:

• a processing system;
• and
• a memory storing computer-executable instructions thereupon which, when executed by the processing system, cause the computing device to perform operations comprising:
• causing a first logical link path and a second logical link path to be established with a remote endpoint in a communications network comprising a plurality of network devices, the first and second logical link paths each comprising an OSI layer 5 link path including intermediate network devices, wherein the first logical link path and the second logical link paths have at least a different intermediate network device, and wherein the first logical link path and the second logical link path are active OSI layer 5 session links that have been established with the remote endpoint;
• establishing a communications session with the remote endpoint using the first logical link path;
• and
• based on a metric indicative of health of the first logical link path, continuing the communications session using the second logical link path.

A system comprising:

• a processing system;
• and
• a memory storing computer-executable instructions thereupon which, when executed by the processing system, cause the system to perform operations comprising:
• determining a first logical link path and a second logical link path between a first endpoint and a second endpoint over a communications network comprising a plurality of network devices, wherein the first logical link path and the second logical link path each comprise an OSI layer 5 link path, and wherein the first logical link path and the second logical link paths have at least a different intermediate network device, and wherein the first logical link path and the second logical link path are active OSI layer 5 session links that have been established between the first endpoint and the second endpoint;
• establishing a communications session between the first endpoint and second endpoint using the first logical link path;
• and
• based on a metric indicative of health of the first logical link path, continuing the communications session using the second logical link path.
