Abstract
A system and method of performing communications over a communications network that uses a communication protocol having multiple different versions, provides for backwards compatibility when devices that support a higher or more secure version of the communication protocol are added to a network having devices that only support a lower or less secure version of the communication protocol. The system and method includes a technique of negotiating and establishing security procedures to be implemented in a communication connection between two devices on the network based on initial session request messages that indicate the version of the communication protocol supported by one or both of the devices. This system and method enable higher and lower protocol version devices (i.e., devices that conform to or that use the same communication protocol but that have different versions of the protocol installed therein) to communicate with one another in the most secure manner, thereby making higher version devices added to a network backward compatible with lower version devices already within the network.
