Packet Processing Engine
The Interphase iSPAN 55MC8 PCI-X™ Packet Accelerator extends the broad Interphase portfolio of communication and network processor solutions for use with PCI-x enabled rack-mount server platform solutions. The iSPAN 55MC8 addresses the growing need for wire-speed packet inspection and processing requirements for the delivery of broadband services in the Wireless, Voice Over IP and IMS network infrastructure.

High Performance – Multicore
The iSPAN 55MC8 is based on the Cavium OCTEON™ Plus high-performance multicore processor architecture which provides:
  • A pin compatible chip that can support 4 to 16 cnMIPS® Plus MIPS 32/64 architecture compatible cores
  • Per core hardware acceleration for packet processing and security including addition of support for Kasumi for wireless security
  • Integrated co-processors for packet I/O, compression/decompression, IDS and anti-virus

With its, powerful onboard OCTEON Plus packet processor, dual management interface and upgradeable memory, the iSPAN 55MC8 is extremely versatile and provides the functionality necessary for migrating to next-generation infrastructures and converged networks.

Cavium Simple Executive and Linux®-based ready-to-use application / protocol suites are available to transform the 55MC8 into a specialized communications interface which can be easily integrated into solution platforms.
