Abstract: A method for congestion management on a computer network including: receiving a packet from a traffic flow; determining at least one attribute associated with the packet; determining a priority level for the packet based on the at least one attribute; determining a queue depth for a queue in a data plane path of the packet; determining whether to send or drop the packet based on the priority level and the queue depth. A system for congestion management including: an incoming packet handler configured to receive a packet; an application detector configured to determine at least one attribute associated with the packet; a policy module configured to determine a priority level for the packet based on the at least one attribute; an enhanced weighted random early detection module configured to determine a queue depth and whether to send or drop the packet based on the priority level and the queue depth.

Abstract: A system and method for radio traffic management in a computer network. The method includes: determining user equipment (UE) status associated with a traffic flow session; determining traffic flow parameters associated with the traffic flow associated with the UE; determining a change in the UE status; and determining a traffic action for at least one packet associated with the traffic flow based on the UE status. The system includes: a UE state module configured to determine UE status associated with a traffic flow session; a packet inspection module configured to determine traffic flow parameters associated with the traffic flow associated with the UE; a forwarding module configured to determine a traffic action for at least one packet associated with the traffic flow based on the UE status.

Abstract: A system and method for diameter agent load balancing. The method including: receiving a request from a sending diameter node; parsing at least one Attribute-Value Pair (AVP) from the request; determining a partition-identifier (partition-id) from the at least one AVP; determining a receiving diameter node, based on the partition-id; and sending the request to the receiving diameter node. The system including: a message module configured to receive a request from a sending diameter node; a parsing module configured to parse at least one Attribute-Value Pair (AVP) of the message from the request and determine a partition-id from the at least one AVP and a receiving diameter node, based on the partition-id; and a forwarding module configured to send the request to the receiving diameter node.

Abstract: A method and system for authorizing traffic flows in a computer network. The method including: receiving a packet from a traffic flow sent by a sender; determining whether the traffic flow has been previously authorized; if the traffic flow has not been previously authorized: determining a subscriber associated with the traffic flow, based on the data retrieved from the packet; requesting authorization from an authorization server based on the subscriber and the data retrieved from the packet; upon receiving a response from the authorization server, sending at least three duplicate acknowledgments to the sender, to generate a retransmission in advance of the standard retransmission timing; otherwise, if the traffic flow has been previously authorized, allowing the packet to continue to a destination.
