Abstract: A method of categorizing a data packet or frame, such as an Ethernet packet or a Sonet frame, where one or more features of the packet or frame are identified and a corresponding priority assigned. At least two priorities, a higher and a lower priority, are used. If none of the sought after features are identified, such as if the packet or frame is of an unknown type, the packet or frame is assigned the higher priority.

Abstract: Preambles of data packets, frames, or cells, such as Ethernet packets, are used to transport information. This information is received, normally as part of a data packet, by a networking element and output there from, normally also as part of a data packet, in order for this informatin to not only be transferred between two neighbouring networking elements. The preamble information may be altered prior to outputtig and may be "piggy backing" on different data packets before and after a networking element. The preamble information may be used as e.g. a separate communication channel, for network management or as a means of increasing the bandwidth of the network.

Abstract: Information is transformed between two link partners (10,20) as Sequence Ordered Sets or Signal Ordered Sets in XGMII or Fibre Channel (18). Such sets are defined to not be amended by intervening PHY's and may be transmitted even when there is no other traffic between the link partners. The information transmitted may be congestion information in a situation where there is heavy traffic in one direction between the link partners (10,20) and little or no traffic in the other direction.

Abstract translation: 在XGMII或光纤通道（18）中，信息在两个链路伙伴（10,20）之间变换为序列排序集或信号有序集。 这样的集合被定义为不被中介PHY修改，并且即使在链路伙伴之间没有其他业务的情况下也可以发送。 所发送的信息可以是在链路伙伴（10,20）之间在一个方向上有大量业务并且在另一个方向上很少或没有业务的情况下的拥塞信息。

Abstract: A pipelined packet processor comprises an initialising unit (14), an OSI Layer 2 processing unit (16), an OSI Layer 3 processing unit (18), an OSI Layer 4 processing unit (20), and a director unit (22). It is advantageous to perform lower layer analysis before higher layer analysis. In this situation, a piece of information proposed by both a lower layer analysis and a higher layer analysis may be finally selected as the higher layer analysis result as the higher layer analysis would normally provide the best proposal for the information. Also, lower level analysis may determine whether and which higher analysis should be performed.

Abstract translation: 流水线分组处理器包括初始化单元（14），OSI层2处理单元（OSI Layer 3处理单元），OSI层4处理单元（20）和导向单元（22）。 在较高层分析之前进行较低层分析是有利的。 在这种情况下，由于较高层分析通常会为信息提供最佳方案，因此可以最后选择较低层分析和较高层分析提出的一条信息作为较高层分析结果。 此外，较低级别的分析可以确定是否应该执行哪些更高的分析。
