This value is within the bandwidth range requested in the Check Request message. The server sets this field to zero if the network path between the Local Site Address and the Local Relay Site Address fails the bandwidth admission policy check.
Maximum Receive Bandwidth (4 bytes): The maximum amount of bandwidth available for receiving data into the Local Relay Site Address. This value is within the bandwidth range requested in the Check Request message. The server sets this field to zero if the network path between the Local Site Address and the Local Relay Site Address fails the bandwidth admission policy check.
