摘要： Disclosed is a method and system for validating a data packet by a network processor supporting a first network protocol and a second network protocol and utilizing shared hardware. The network processor receives a data packet; identifies a network packet protocol for the data packet; and processes the data packet according to the network packet protocol comprising: updating a first register with a first partial packet length specific to the first network protocol; updating a second register with a second partial packet length specific to the second network protocol; and updating a third register with a first checksum computed from fields independent of the network protocol. The system produces a second checksum utilizing a function that combines values from the first register, the second register, and the third register. The system validates the data packet by comparing the data packet checksum to the second checksum.

摘要： A method and apparatus for assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. In a given processing period, sinks that are available to receive work are identified and sources qualified to send work to the available sinks are determined taking into account any assignment constraints. A single source is selected from an overlap of the qualified sources and sources having work available. This selection may be made using a hierarchical source scheduler for processing subsets of supported sources simultaneously in parallel. A sink to which work from the selected source may be assigned is selected from available sinks qualified to receive work from the selected source.

摘要： A method and structure for determining when a frame of information comprised of one or more buffers of data being transmitted in a network processor has completed transmission is provided. The network processor includes several control blocks, one for each data buffer, each containing control information linking one buffer to another. Each control block has a last bit feature which is a single bit settable to “one” or “zero” and indicates when the data buffer having the last bit is transmitted. The last bit is in a first position when an additional data buffer is to be chained to a previous data buffer indicating an additional data buffer is to be transmitted and a second position when no additional data buffer is to be chained to a previous data buffer. The position of the last bit is communicated to the network processor indicating the ending of a particular frame.

摘要： A system and method of moving information units from an output flow control toward a data transmission network in a prioritized sequence which accommodates several different levels of service. The present invention includes a method and system for scheduling the egress of processed information units (or frames) from a network processing unit according to service based on a weighted fair queue where position in the queue is adjusted after each service based on a weight factor and the length of frame, a process which provides a method for and system of interaction between different calendar types is used to provide minimum bandwidth, best effort bandwidth, weighted fair queuing service, best effort peak bandwidth, and maximum burst size specifications. The present invention permits different combinations of service that can be used to create different QoS specifications. The “base” services which are offered to a customer in the example described in this patent application are minimum bandwidth, best effort, peak and maximum burst size (or MBS), which may be combined as desired. For example, a user could specify minimum bandwidth plus best effort additional bandwidth and the system would provide this capability by putting the flow queue in both the NLS and WFQ calendar. The system includes tests when a flow queue is in multiple calendars to determine when it must come out.

摘要： The transport protocol for communicating between general purpose processors acting as contact points and network processors in a packet processing environment such as Ethernet is provided. In such an environment, there is at least one single control point processor (CP) and a plurality of network processors (NP), sometimes referred to as blades. A typical system could contain two to sixteen network processors, and each network processor connects to a plurality of devices which communicate with each other over a network transport, such as Ethernet. The CP typically controls the functionality and the functioning of the network processors to function in a way that connects one end user with another, whether or not the end user is on the same network processor or a different network processor. There are three types of communication provided; first, there is communication generally referred to as control services and normally there will be only one pico processor which operates as a GCH (guided cell handler) and only one that operates as a guided tree handler (GTH). A path is provided for the controls to the GCH and the GTH commands, and a separate path is provided for the data frames between the GDH's (general data handler) and the CP.

摘要： An improved method and system for generating a frame check sequence. A multiple-bit data string, M, is received in which M is of the form: anbncndnan−1bn−1cn−1dn−1 . . . a2b2c2d2a1b1c1d1. M is thereafter parsed into multiple subframes of the form: anan−1an−2 . . . a2a1; bnbn−1bn−2 . . . b2b1; cncn−1cn−2 . . . c2c1; and dndn−1dn−2 . . . d2d1. The subframes are padded with zeros resulting in subframes of the form: an000an−1000an−2000 . . . a2000a1000; 0bn000bn−1000bn−200 . . . 0b2000b100; 00cn000cn−1000cn−20 . . . 00c2000c100; and 000dn000dn−1000dn−2 . . . 000d2000d1. A partial check sum is then generated for each of the multiple subframes. Finally, each of the partial check sums are added together such that a frame check sequence for M is obtained.
