Abstract
What is disclosed is a method for efficient capture and streaming of data packets in a network device comprises capturing data packets matching predetermined filters, packaging said data packets into samples, and aggregating one or more samples in a high speed bus payload. The method also comprises transferring said high speed bus payload to a CPU, extracting said samples from the high speed bus payload and storing said samples in a shared memory of the CPU, and accessing said samples from the shared memory for streaming to one or more client.
Claims8
A method for analysis of data packets at a network device having an input port configured to receive a plurality of packets from a network and an output port configured to transmit the data packets to the network, the method comprising:
- capturing, by a programmable processor, one of said plurality of packets received on the input port matching one or more predetermined criteria;
- creating, by the programmable processor, one or more metadata related to the captured packet;
- sending, from the programmable processor, a sample comprising a copy of said captured packet along with the metadata, to a processor via a high speed bus;
- and
- streaming, via said programmable processor, the sample to one or more clients.
A network device comprising:
- an input port configured to receive a plurality of data packets from a network;
- a programmable packet capture processor configured to capture one of said data packet received on the input port matching one or more predetermined criteria and to create one or more metadata related to the captured packet and to send a sample comprising a copy of said captured packet along with the metadata, to a processor of said network device via a high speed bus and to stream the sample to one or more clients.
