A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.

The present invention is directed to communications apparatus, systems, and methods for preventing and/or minimizing session data clipping/loss when using the ICE protocol procedures on a session border controller. An exemplary method embodiment of operating a Session Border Controller (SBC) includes, receiving, at the SBC, an initial offer message from a first user equipment device directed to a second user equipment device, said initial offer message including one or more candidate addresses for the first user equipment device; and establishing a data path between the SBC and the second user equipment device in response to receiving said initial offer message prior to establishing a data session between the first user equipment device and the session border controller.

Server devices operating on the Internet or another wide area network (WAN) are able to locate client devices using address information obtained from a shared location. Client devices initially determine their own network address information and submit the determined information for a priori storage at the shared location on the WAN. Each server device, in turn, contacts a message service or the like to establish a persistent data connection that is maintained between the message service and the server device over time. After the client device stores its own address information, the client initiates contact with the server via the message service having the previously-established persistent connection. Upon receipt of the instruction from the message service, the server is able to retrieve the client's previously-stored address information from the WAN storage and use the information to establish a connection with the client.

Techniques are described for forming on-demand mesh connections between spoke routers of a Software-Defined Wide Area Network (SD-WAN) arranged in a hub-and-spoke topology. A first spoke router modifies the first packet to include metadata specifying first reachability information and first Internet Protocol (IP) address information for the first spoke router. The first spoke router forwards the first packet to a hub router for forwarding to a second spoke router. The first spoke router receives a second packet from the hub router that includes metadata specifying second reachability information and second IP address information for the second spoke router. In response to determining that the first reachability information is compatible with the second reachability information, the first spoke router initiates a peering connection with the second spoke router along a path which bypasses the hub router for forwarding subsequent packets of the forward packet flow.
