METHOD FOR STREAMING PACKET CAPTURES FROM NETWORK ACCESS DEVICES TO A CLOUD SERVER OVER HTTP

摘要

A system for streaming packet captures over the Internet includes multiple network access devices, each operating as one of a gateway device, a wireless access point, and a network switch, and a management server communicatively coupled to the network access devices over the Internet for managing the network access devices. The management server maintains a persistent hypertext transport protocol (HTTP) connection with each of the network access devices over the Internet. The management server is to generate a bytecode based on a filtering expression for packet captures (PCAPs) representing one or more PCAPs filtering rules, transmit the bytecode to the network access devices without requiring the network access devices to compile the PCAPs filtering rules, receive PCAPs from the network access devices captured by the network access devices based on the PCAPs filtering rules, and merge the PCAPs received from the network access devices into merged PCAPs.

1. A system for streaming packet captures over the Internet, comprising:
a plurality of network access devices, wherein each of the network access devices provides network access to a plurality of client devices over a local area network (LAN); and a management server communicatively coupled to the network access devices for managing the network access devices, wherein the management server is configured to:
transmit a bytecode to at least a portion of the network access devices, the bytecode based on a filtering expression for packet captures (PCAPs), the bytecode representing one or more PCAPs filtering rules;receive PCAPs from at least a portion of the network access devices, wherein the PCAPs were captured by the network access devices based on the PCAPs filtering rules; andmerge the PCAPs received from the network access devices into merged PCAPs.
