This disclosure describes techniques that include associating a timestamp with a network packet, and carrying the timestamp or otherwise associating the timestamp with the network packet during some or all processing by the system described herein. In one example, this disclosure describes a method that includes receiving, at an ingress port of a device, an initial portion of a network packet; storing, by the device, timestamp information associated with receiving the initial portion of the packet; and determining, by the device, whether to transmit information derived from the initial portion of the network packet.

Low latency packet switch architecture

This disclosure describes techniques that include representing, traversing, and processing directed graphs using one or more content-addressable memory devices. In one example, this disclosure describes a method that includes presenting query data to one or more ternary content-addressable memory (TCAM) devices, wherein the query data includes state data and key data; receiving, from the TCAM devices, information about a matching address identified by the TCAM devices; accessing, based on the information about the matching address, information in one or more storage devices; performing, based on the information in the one or more storage devices, at least one operation on data included within the one or more storage devices to generate processed data; outputting the processed data; determining, based on the information in the one or more storage devices, new state data and a new key value; and presenting new query data to the TCAM devices.

Directed graph traversal using content-addressable memory

Aspects of this disclosure describes techniques for parsing network packets, processing network packets, and modifying network packets before forwarding the modified network packets over a network. The present disclosure describes a system that, in some examples, parses network packets, generates data describing or specifying attributes of the network packet, identifies operations to be performed when processing a network packet, performs the identified operations, generates data describing or specifying how to modify and/or forward the network packet, modifies the network packet, and outputs the modified packet to another device or system, such as a switch.

Flexible processing of network packets

This disclosure describes techniques that include storing, during parsing of a data unit or a network packet, information (i.e., 'summary information') that identifies how the network packet has been process and/or other aspects of the parsing process. In one example, this disclosure describes a method that includes parsing a packet header from a data unit, wherein parsing the packet header includes storing in result vector storage each of a plurality of data items derived from the packet header, the result vector storage having a result vector format defining fields within the result vector storage for storing each of the plurality of data items; storing in template storage, for each of the plurality of data items, summary information about the plurality of data items stored in the result vector storage; and processing, by the packet-processing integrated circuit and based on the summary information and the plurality of data items, the network packet.
