Geographic redundancy at session border controllers based on host name schemes

A method comprising:

• provisioning each of geographically redundant network devices with multiple host names in correspondence to each geographically redundant network device, wherein one of the multiple host names include a primary host name associated with one of the geographically redundant network devices and a remainder of the multiple host names include one or more secondary host names associated with the other one or more geographically redundant network devices;
• receiving, by the one of the geographically redundant network devices, one or more packets;
• determining, by the one of the geographically redundant network devices, a host name mapping for the one or more packets;
• rewriting, by the one of the geographically redundant network devices, the one or more packets to include one of the multiple host names corresponding to the host name mapping;
• and
• forwarding the one or more packets to another device.

A network device configured to:

• store a host name mapping that includes a host name shared with at least one other network device, wherein the network device provides geographic redundancy to another device;
• receive one or more packets originating from an end device;
• inspect one or more headers associated with the one or more packets;
• determine whether the host name shared with the at least one other network device is to be utilized based on the one or more headers inspected;
• rewrite the one or more headers to include the host name when it is determined that the host name is to be utilized;
• and
• forward the one or more packets to the other device.

A network device configured to:

• store a host name mapping scheme that include multiple host names corresponding to the network device and one or more other network devices, wherein one of the multiple host names includes a primary host name associated with the network device and a remainder of the multiple host names includes one or more secondary host names corresponding to the one or more other network devices;
• receive one or more packets originating from an end device;
• inspect one or more headers associated with the one or more packets;
• determine whether the primary host name or one of the one or more secondary host names is to be utilized based on the one or more headers inspected;
• rewrite the one or more headers to include the primary host name when it is determined that the one or more packets originate from the end device in which the network device is a primary network device;
• rewrite the one or more headers to include one of the one or more secondary host names when it is determined that the one or more packets originate from the end device in which the network device is a secondary network device;
• and
• forward the one or more packets to another device.
