  1. ERX Overview Carrier Class Edge Switch Router

  2. Unisphere Data Services Overview • Redstone incorporated in September 1997 • Headquarters: Westford, Massachusetts • Joined Unisphere Solutions, a US-based, wholly-owned subsidiary of Siemens AG in April, 1999 • The company is dedicated to addressing the challenges faced by service providers as they strive to keep pace with the rapid growth and demand for new services at the edge of the Internet

  3. Unisphere Data Services Overview • Redstone co-founders: • Jim Dolce: Former Vice President & General Manager, Remote Access Business Unit, Cascade Communications • Kurt Melden: Former co-founder and hardware development director, Cascade Communications • Chris Lawler: Former Vice President of Engineering, LAN Switching Division, 3Com Corp • Products: ERX700 and ERX1400 Edge Switch Routers and NMC-RX (EdgeControl) NMS

  4. Market Segmentation • Internet Edge • Where service providers “meet” their customers • For end-users: Dedicated Internet and VPN access • For service providers: • Service adaptation to IP • Policy management • IP VPN management • Statistics Harvesting • Accounting • IP routing with QoS “Between now and 2002, 2 million businesses and 30 million consumers will get connected to the Internet,” Forrester, 8/1998, Network Strategies

  5. 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 can’t keep up with today’s traffic demands • Lack of carrier features challenge ability to meet SLA commitments • No QoS control limits new services Cisco 7500 Ascend 9000 OC3/STM1 Internet Access Customers Cisco 7500 FT1/E1 T1/E1

  6. Next-Generation IP Edge Switch Router • High Density (low power, small size) to conserve scarce point-of-presence (POP) rack space • Hundreds of physical circuits/shelf • Thousands of logical circuits/shelf • High bandwidth capacity with 100% Wire Speed Performance • Hardware redundancy and other Carrier reliability features provide high availability required to meet SLAs • Supports wire speed QoS crucial to deployment of the business-grade Internet

  7. Industry Leading Density Available space in COs remains at a premium ! 7 ft Telco Rack ERX 1400 + 100% Wire Speed Efficiency + Full Hardware Redundancy + Support for QoS

  8. Wire Speed Performance Packet Distribution on the Internet Source: MCI Traffic Study, IEEE Network 11/97

  9. 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

  14. 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

  15. NMC-RX (EdgeControl) Interface Examples

  16. Monitoring and Diagnostics • A full suite of tools to support ease of operation and speed problem resolution • Comprehensive statistics for all interfaces • Hard-wired hardware and firmware identification per line module, including revision level • Detailed event logging and event filtering • Diagnostic tests on power up or on command • Diagnostic tests for line modules and protocol types • Loopback tests at physical and logical levels • Test pattern generation at physical and logical levels • Dump capabilities for line modules and SRP
