IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP IOP ATM Advanced Fabric Architecture • Fabric distributed over Cell Switching Modules (CSMs), MPM-C and Frame Cell Switching Module (FCSM) • i.e., there is no central switch fabric Distributed switching fabric Input/Output processor and buffering

  9. Scalable Fabric Capacity • fabric capacity increases as modules are added • low entry cost • economical expansion Fabric capacity (Gbps) # of OC-3c/STM-1 ports

  10. X-Cell: Advanced Fabric Architecture Buffer Memory (2.048M Cells) • Distributed Input Buffered with Output Control (DIBOC) • logically identical to output buffered switch Input Ports Output Ports Fabric (13.2G)

  11. X-Cell’s buffer management • Characteristics • Dynamic Input Buffered with Output Control (DIBOC) • 6 classes of service: CBR PRS, CBR, rt-VBR, nrt-VBR, UBR • very large cell buffers: 128K per OC12c/STM-4c port • thresholds and discarding mechanisms: EPD, PPD and RED • Implementation • Input state and the output state of IOP ASIC

  12. Massive cell buffer capacity • Very high PER PORT cell buffer capacity • 25M: 1,024 • OC3c/STM-1 8,192 • OC12c/STM-4c 131,072 • That’s 1,048,576 cell buffer capacity in Omni-5x/5Wx & 2,097,152 cell buffer capacity in Omni-9x/9Wx! • Essential for LAN applications • ATM switches must absorb very large, momentary traffic bursts without discarding cells • Essential for LAN-to-WAN access • ATM switches must flow-control campus ATM traffic to lower-speed wide area transmission

  13. OmniSwitch Modules

  14. MPM-C • Features: • Management processor module for OmniSwitch ATM • Does not require any FCSM2. • Out-band Management Ethernet port. • Support redundant MPM-C. • ATM Switching only, no Frame modules can be installed in the OmniSwitch • Up to 32 MB Flash (8) • Up to 128 MB Dram (32) • 256 MB SDRAM (64) • Faster CPU: uses a SPARCLite 860 running at 160Mhz

  15. MPM-C • Benefits: • Cost Effective solution when building an ATM Network. • No need for additional FCSM. • Single slot solution provides higher port density: 64 OC-3 or 16 OC-12. • In-band management can be provided by: • one LANE Client, • or one Ptop service, • or one CIP service. • Performance is 170 calls/sec.
