A method is provided in one example embodiment and includes indentifying a delay within one or more queues in a service element by evaluating a type of packet sought for processing in the service element. The method also includes comparing the delay to a threshold value to determine whether to adjust a processing mode of the service element. In more specific embodiments, the method includes providing a flow table that maps specific packets of a flow traversing the service element for receiving a certain amount of processing from a processor engine. The adjustment can include avoiding opening new flows for the service element, or providing continued service to a selected few flows and not others, or avoiding processing for certain types of services having less priority.

System and method for detection and delay control in a network environment

A dispatching technique dispatches packets to a plurality of service control engines (SCEs) which in aggregate may be configured to handle traffic produced by a high-speed high-capacity data link. Upstream and downstream packets that are associated with a data flow between a subscriber and a destination node in a communication network are received from by a dispatcher which is located in a path used by the data flow. For each packet, the dispatcher identifies an SCE from among a plurality of SCEs that is to receive the packet based upon an address contained in the packet. The packet is then dispatched by the dispatcher to the identified SCE which processes the packet accordingly. After processing the packet, the SCE returns the packet to the dispatcher which further processes the packet including transferring the packet onto the communication network towards its destination.
