  • Methods for server-driven packet congestion control
    Patent number: 8516556
    Abstract: Methods for congestion control by a AAA server are provided. In an embodiment of the invention a hint indicator is embedded in reply messages from a AAA server. In subsequent messages received by that AAA server, the AAA server determines when the hint indicator is present. Processing decisions for the subsequent message are based on the presence of the hint indicator. In another embodiment, a method for congestion control at the AAA server is provided. At the AAA server a message received from a network access server is stored and timestamped in an ingress message queue. A congestion state for the AAA server is determined based on an ingress queue state and a message age state. The message is processed based on the congestion state. In alternative embodiments, message processing is based on the congestion state, message type and number of round trip messages.
