System and method of distributing digital content

A method comprising:

• sending a data packet, or a copy of the data packet, from a first video distribution hub to a second video distribution hub, wherein the first video distribution hub is coupled to a first link and to a second link, wherein sending comprises:
• in response to the second link being intact, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a primary network path that includes the second link and excludes the first link;
• and
• in response to a failure of the second link, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a backup network path that includes the first link and that does not include the second link, wherein the backup network path is selected from one of a primary backup network path, a secondary backup network path, and a tertiary backup network path based on one or more selection factors;
• wherein the primary backup network path includes a first plurality of nodes of a first network ring of a cascaded network ring architecture, wherein the cascaded network ring architecture is associated with the first video distribution hub and the second video distribution hub;
• wherein the secondary backup network path includes a second plurality of nodes of a second network ring of the cascaded network ring architecture;
• wherein the tertiary backup network path includes a third plurality of nodes of a third network ring of the cascaded network ring architecture;
• wherein at least one node of the first plurality of nodes differs from each of the second plurality of nodes and at least one node of the third plurality of nodes differs from each node of the first plurality of nodes and differs from each node of the second plurality of nodes;
• wherein the data packet, or the copy of the data packet, is sent via the primary backup network path when the primary backup path is selected;
• wherein the data packet, or the copy of the data packet, is sent via the secondary backup network path when the secondary backup path is selected;
• and
• wherein the data packet, or the copy of the data packet, is sent via the tertiary backup network path when the tertiary backup path is selected.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause the processor to:

• send a data packet, or a copy of the data packet, from a first video distribution hub to a second video distribution hub, wherein the first video distribution hub is coupled to a first link and to a second link, wherein sending the data packet, or a copy of the data packet, comprises:
• in response to the second link being intact, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a primary network path that includes the second link and excludes the first link;
• and
• in response to a failure of the second link, sending the data packet, or the copy of the data packet, from the first video distribution hub to the second video distribution hub via a backup network path that includes the first link and that does not include the second link, wherein the backup network path is selected from one of a primary backup network path, a secondary backup network path, and a tertiary backup network path based on one or more selection factors;
• wherein the primary backup network path includes a first plurality of nodes of a first network ring of a cascaded network ring architecture, wherein the cascaded network ring architecture is associated with the first video distribution hub and the second video distribution hub;
• wherein the secondary backup network path includes a second plurality of nodes of a second network ring of the cascaded network ring architecture;
• wherein the tertiary backup network path includes a third plurality of nodes of a third network ring of the cascaded network ring architecture;
• wherein at least one node of the first plurality of nodes differs from each of the second plurality of nodes and at least one node of the third plurality of nodes differs from each node of the first plurality of nodes and differs from each node of the second plurality of nodes;
• wherein the data packet, or the copy of the data packet, is sent via the primary backup network path when the primary backup path is selected;
• wherein the data packet, or the copy of the data packet, is sent via the secondary backup network path when the secondary backup path is selected;
• and
• wherein the data packet, or the copy of the data packet, is sent via the tertiary backup network path when the tertiary backup path is selected.
