摘要： A packet processing pipeline is configured to classify packets received via a network based on information in the received packets: (1) as belonging to one of a plurality of identified flows, or (2) as not belonging to any of the plurality of identified flows. For each received packet determined not to belong to one of the previously identified flows, the pipeline sends at least a portion of the packet or a corresponding packet descriptor to a processing unit. For each received packet determined not to belong to one of the previously identified flows, the processing unit defines a new flow corresponding to the packet based on an analysis of the portion corresponding packet descriptor, and configures the packet processing pipeline to handle the new flow.
摘要翻译：分组处理流水线被配置为基于接收到的分组中的信息对经由网络接收的分组进行分类：（1）属于多个识别的流中的一个，或者（2）不属于多个识别流中的任何一个。对于被确定为不属于先前识别的流之一的每个接收到的分组，流水线将分组的至少一部分或相应的分组描述符发送到处理单元。对于确定不属于之前识别的流之一的每个接收到的分组，处理单元基于对相应分组描述符的部分的分析来定义与分组对应的新流，并且配置分组处理流水线来处理新流。

In one embodiment, an integrated chip is implemented with two or more address tables. The two or more address tables are implemented with separate memory tables to store addresses. The two or more address tables are comprised of a first address table and a second address table. Connection lines connect the first address table and the second address table to create a cascaded address table. Search logic initiates a search of the first address table for an address. If the address is not found, the search logic initiates a search of the second address table through the connection lines.

摘要： Linked list profiling and updating techniques define subsets of linked list entries that are executed upon various resource calls. The subsets are defined by linked list profiles. The techniques can add/remove linked list entries to/from these profiles in a flexible update manner, in which a profile table is used to store profiles, or in atomic manner, in which each linked list entry itself contains profile data. Implemented in a communication system network device, the techniques are used to define and update profiles of physical or virtual ports used for packet-based egress and ingress communications.

摘要： An apparatus for forwarding packets includes a packet processing pipeline having a processing unit that processes packets compliant with a recognized communication protocol. A first port coupled to the packet processing pipeline is configured to receive a packet that does not comply with the recognized communication protocol and has a header that conforms to a second communication protocol. A data extraction unit extracts first destination information from the header of the packet and, based on the first destination information, generates second destination information that conforms to the recognized communication protocol. The processing unit determines, based on the second destination information, an egress interface to which the packet is to be forwarded.
