First Generation Edge Solutions

• Current generation of Edge products limit
  Internet access!
• Limited density is exhausting POP space and power
• Performance designed for larger packet sizes
  cant keep up with todays traffic demands
• Lack of carrier features challenge ability to
  meet SLA commitments
• No QoS control limits new services

Wire Speed Performance

• Growth in demand for bandwidth and function (e.g.
  QoS) is outpacing the performance of pure
  software routers based solely on RISC processors
• Next Generation IP Edge Router designs require a
  precise blend of RISC and ASIC technology...
• Ultimate flexibility of a RISC processor
• Performance, density and cost benefits of a
  hardware solution
• Edge Routers have less stringent forwarding
  requirements but demand more features and
  flexibility

10
Fast, Flexible Architecture

• ASICs and FPGAs per line card deliver hardware
  assist for maximum performance
• Buffer and queue management
• QoS scheduling
• Address lookup
• Flow classification and rate measurement
• Statistics support
• RISCs per line card for flexibility
• L2/L3 packet header parsing and modifications
• QoS, classification, and statistics control
• Emerging standards support

11
Carrier Reliability

• NEBS Level 3 compliance
• Full redundancy and hot swap
• Distributed DC power and efficient power
  utilization (1KW for 924 T1s)
• Front-to-back airflow
• Midplane design means service uptime without
  cable moves
• Modular software architecture supports dynamic
  upgrades
• Storage of multiple images and configurations to
  ease service upgrades

Benefit Service Providers can safely deliver
network reliability guarantees as part of SLAs

Network Element Management Overview

• Standards-based element management SNMP, MIB
  support, and CLI
• Cisco-interpreter CLI mode eliminates need for
  operator retraining and fully utilizes existing
  scripts
• CLI scripting language automates standard
  configuration tasks
• NMC-RX (EdgeControl), JAVA-based NMS with
  relational database eases network-wide policy
  control
• Statistics and accounting information gathered
  down to the packet flow level
