Sdwan data-plane resiliency for extended survivability

A system comprising:

• a processor;
• and
• a non-transitory memory storing computer-executable instructions thereon, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations comprising:
• receiving, at a static edge device associated with a static wide area network (WAN) Internet Protocol (IP) address in a data plane of a software-defined wide area network (SDWAN), data from a first device communicating through an edge device of a first Internet service provider (ISP) of the SDWAN, wherein the first device is associated with a private IP address;
• associating, by the static edge device, the first device with the private IP address;
• communicating, by the static edge device, with the first device at the private IP address;
• determining, by the static edge device, isolation from one or more controllers;
• and
• automatically extending, by the static edge device and based on the determining of isolation from the one or more controllers, a lifetime of a security parameter.

A non-transitory computer-readable medium storing instructions thereon, wherein the instructions, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, at a static edge device associated with a static wide area network (WAN) Internet Protocol (IP) address in a data plane of a software-defined wide area network (SDWAN), data from a first device communicating through an edge device of a first Internet service provider (ISP) of the SDWAN, wherein the first device is associated with a private IP address;
• associating, by the static edge device, the first device with the private IP address;
• communicating, by the static edge device, with the first device at the private IP address;
• determining, by the static edge device, isolation from one or more controllers;
• and
• automatically extending, by the static edge device and based on the determining of isolation from the one or more controllers, a lifetime of a security parameter.
