摘要： An efficient method for performing state based ingress packet selection for a packet processing system in a network processor is disclosed. With this method, each set of message classes is associated with a state of an application, and each set of message classes is assigned to a semaphore. The application blocks one of the semaphores based on its current state. When a message is received, and the message belongs to a class assigned to the blocked semaphore, the blocked semaphore is signaled. The blocked semaphore then wakes the application. In this manner, when the application is awakened, it is guaranteed to find a message that it is interested in processing in its current state, resulting in greater efficiency in the processing of ingress messages.

摘要： A method and apparatus for developing portable packet processing applications on network processors includes a docking platform which provides a common interface for individual packet processing applications to be plugged into the network processing environment. Each application interacts with the docking platform through the common interfaces provided by the latter. The docking platform interacts with the other modules inside the system to accomplish the requests from the application. In this manner, the applications become “shielded” from the implementation details of the underlying hardware. The applications need not change when the network processor hardware features are changed. It therefore provides a universal packet processing programming environment in which applications can execute in a portable and flexible manner in various hardware architectures.

摘要： A method for controlling congestion control and avoidance behavior of a plurality of heterogeneous network processors in a network is disclosed. The network also includes at least one host processor that utilizes at least one congestion control application. The method include providing a plurality of generic application program interfaces (APIs). The generic APIs communicate with the congestion control application(s) and the heterogeneous network processors. The generic APIs communicate with the congestion control application(s) in the host processor(s) in a network processor independent manner, but manage the congestion control and avoidance behavior of the heterogeneous network processors in a network processor specific manner. Thus, the generic APIs allow the control application(s) to be network processor independent and to manage the congestion control and avoidance behavior of the heterogeneous network processors in the network processor specific manner.
