Product Overview


  • Advanced layer 2 through layer 7 content matching capabilities
  • Gluelessly interfaces with many network processors using synchronous SRAM (ZBT or Sync Burst) bus operating up to 6.4 Gbps. System interface supports DMA mode for data transfer
  • Supports 8Kbyte maximum packet size
  • Classification and analysis up to OC48 speed using header, payload or user-defined data
  • Key length programmable from 1 to 192 bytes
  • Provides 16K policy database entries with one classification processor and 128K entries with eight classification processors
  • Performs forward and reverse content searches
  • Policy database configurable into multiple partitions with each partition storing a different class of rules
  • Searches executed sequentially, conditionally and/or in parallel using sophisticated chaining mechanisms
  • Supports up to 32 independent input/output request/response data channels
  • Interfaces to an optional SSRAM for extended capabilities such as programmed search sequencing, per rule statistics collections, timestamp, and user data.
  • IPv4 aware and IPv6 ready
  • Software Developer's Kit (SDK), available separately, accelerates application development.
  • Typical Applications include:
