Question: What happens to TCP-based media flows when a PS-PS (Packet Switched - Packet Switched) session transfer occurs with an IP address change in an IMS (IP Multimedia Subsystem) environment?
Option 1: The media flows seamlessly continue using the new IP address without interruption.
Option 2: The TCP connections for media flows break, requiring application-specific recovery procedures.
Option 3: The IMS automatically initiates a handover for affected media flows to prevent disruption.
Option 4: The change in IP address has no impact on ongoing TCP-based media flows.
Explanation: During a PS-PS session transfer with an IP address change, the alteration in network connectivity disrupts the continuous flow of data packets for TCP connections. Since TCP relies on consistent IP addressing for its connection-oriented approach, a change in IP address will cause existing TCP connections to break. Recovery from such broken connections depends on the specific application managing those media flows, as each may have its own mechanisms for re-establishing connectivity.
