Abstract:
1. A computing device-implemented method comprising: receiving a Session Initiation Protocol (SIP) response that includes a load header associated with a downstream SIP device, the load header including information identifying a first load status of the downstream SIP device; determining, based on the first load status, an amount of traffic to send to the downstream SIP device, sending the determined amount of traffic to the downstream SIP device; determining, during a monitoring time period after sending the determined amount of traffic, whether a second load status is received from the downstream SIP device; determining, based on determining whether the second load status is received from the downstream SIP device, whether reducing the amount of traffic to send to the downstream SIP device, when the trigger is received, is successful; determining that reducing the amount of traffic to send to the downstream SIP device is unsuccessful when the second load status is not received; and further reducing the determined amount of traffic when reducing the amount of traffic to send to the downstream SIP device is unsuccessful.
