ABSTRACT:
An apparatus is described that facilitates selective mirroring through processing of network traffic in accordance with provisioned rules and policies. The apparatus includes a port included in a set of at least one port, wherein each port in the set receives input traffic, a data processor that processes input data from the set of at least one port to generate mirrored data, based on rules with bitwise granularity across a header and a payload of the input data, and a mirror port selectable from the set of at least one port that transmits output traffic corresponding to the mirrored data. Advantageously, the apparatus provides an architectural framework well suited to a low cost, high speed, robust implementation of selective mirroring that enables flexible, advanced network security and monitoring features and network traffic analysis.
