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.

Align/notify compression scheme in a network diagnostic component

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.

Random data compression scheme in a network diagnostic component

A data alignment system suitable for use in manipulating the positioning of a designated portion of a data stream transmitted by a high speed communications system, so as to facilitate further processing of the data carried by the data stream. The data alignment system includes a detector and an alignment component in communication with each other. In operation, the detector locates and identifies, in accordance with suitable instructions, the designated portion of the data stream. The alignment component then repositions, in accordance with suitable instructions, the designated portion of the data stream at a predetermined location within the data stream.

Systems and methods for data alignment

Systems, device and methods are provided for determining a reference clock frequency for use by a multi-protocol analyzer in connection with a multi-protocol communications system. Initially, the clock frequencies for each of the links in the multi-protocol communications system are determined. The link clock frequencies are then used as a basis for determining the frequency of the reference clock. While the reference clock frequency is based upon the link clock frequencies, the reference clock frequency is different from each of the reference clock frequencies.

Systems and methods for definition and use of a common time base in multi-protocol environments

A programmable data filtering/searching system for use with a data network. The primary programmable hardware-based filtering and searching portions of the system are integrated onto the same printed circuit board as the data storage device to facilitate efficient filtering and searching of data from a data stream coming from a memory storage device after being captured. In addition, the actual hardware and software used to perform the filtering and searching routines is programmable such that various filter and search criteria can be entered and utilized. The data filtering/searching system also uses metadata in addition to the captured data to minimize the time required to perform certain processes on the data from the data stream.
