Filed:

Oct 15, 2018

Appl. No.:

16/160609

Inventors:

- Santa Clara CA, US
Srihari Raju Vegesna - San Jose CA, US

International Classification:

H04L 29/06
H04L 12/741

Abstract:

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.

Abstract:

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.

Abstract:

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.
