Abstract
A method, apparatus, and computer-readable media are presented that provide a configuration that sets up and maintains communication connections through the use of Network Address Translation. The configuration includes communicating, by a device, packets from and/or to another device, in which the communication involves a network address translation, and maintaining the network address translation by transmitting, by the device, packets using the network address translation frequently enough to prevent any intermediate device from deleting a mapping for the network address translation from a cache of the intermediate device.
Claims15
A method comprising:
- communicating, by a device, packets from and/or to another device, wherein the communication involves a network address translation;
- and
- maintaining the network address translation by transmitting, by the device, packets using the network address translation frequently enough to prevent any intermediate device from deleting a mapping for the network address translation from a cache of the intermediate device.
An apparatus comprising at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus to
- communicate packets, wherein the communication involves a network address translation;
- and
- maintain the network address translation by transmitting packets using the network address translation frequently enough to prevent any intermediate device from deleting a mapping for the network address translation from a cache of the intermediate device.
A non-transitory computer readable media, comprising program code for causing a processor to perform instructions for
- communicating, by a device, packets from and/or to another device, wherein the communication involves a network address translation;
- and
- maintaining the network address translation by transmitting, by the device, packets using the network address translation frequently enough to prevent any intermediate device from deleting a mapping for the network address translation from a cache of the intermediate device.
