    摘要: A synchronous network traffic processor that synchronously processes, analyzes and generates data for high-speed network protocols, on a wire-speed, word-by-word basis. The synchronous network processor is protocol independent and may be programmed to convert protocols on the fly. An embodiment of the synchronous network processor described has a low gate count and can be easily implemented using programmable logic. An appropriately programmed synchronous network traffic processor may replace modules traditionally implemented with hard-wired logic or ASIC.

    摘要: A network diagnostic component or device that is placed in-line between a first and second node. The diagnostic component or device is used to compress a random data signal. For example, the first node may communicate with the second node using a random data signal that includes random data units that represent a first data unit. In some embodiments, the random data signal may be of the Serial Attached Small Computer System Interface (“SAS”)/Serial Advanced Technology Attachment (“SATA”) protocol. The network diagnostic component may receive the random data signal and associate at least one random data unit with identifier that is indicative of the first data unit. This random data unit may be recorded in a memory. A representation of the random data units that are different from the random data unit associated with the identifier is also recorded in the memory.

    摘要: The embodiments disclosed herein relate to a network diagnostic component or device that is placed in-line between a first and second node. The diagnostic component or device is used to compress pre-specified Dwords of a network data stream. For example, the first node may communicate with the second node using a network data stream that includes a first component and a pre-specified component. In some embodiments, the network data stream may be of the SAS/SATA protocol. The network diagnostic component may receive the network data signal and associate the pre-specified component with an identifier that is represents the pre-specified component. The first component and the identifier representing the pre-specified component may then be recorded in a memory.
