Overview

Command pgw is a dead simple implementation of P-GW only with GTP-related features.

P-GW follows the steps below if there's no unexpected events in the middle. Note that the Gx procedure is just mocked to make it work in standalone manner.

1. Wait for Create Session Request from S-GW.

2. Send Create Session Response to S-GW if the required IEs are not missing, and start listening on the interface specified with s5u flag.

3. If Modify Bearer Request comes from S-GW, update bearer information.

4. If T-PDU comes from S-GW, print the payload of encapsulated packets received, and respond to it with payload(ICMP Echo Reply).
