  1. ANI ATM Interfaces Anthony Alegrete Product Line Manager

  2. Agenda • Why ATM? • Hardware • Software Features • Configuration Examples • Competitive • CMM Memory • Ordering Information • Summary

  3. Why ATM? • ATM Backbones • Provide connectivity for Ethernet networks over ATM • Easy migration solution from existing ATM network to Ethernet • Alcatel benefits • Provides embedded ATM uplink capability for OS7000 • Utilizes carrier class system availability • Lowers transition costs (no need for separate ATM to GigE chassis) • Less boxes to manage • Standards based • Takes full advantage of integrated security solution • Integral part of Alcatel management solution

  4. HardwareChassis • CMM memory • Redundancy requires 128M flash memory upgrade • Upgrade kit • New 128M bundles • New 128M CMMs • Primary CMM failover will not interrupt established PVCs • Hot-swapping and insertion same as current NIs • Module type, module revision level, part number, can be determined via SNMP, CLI and/or WebView

  5. HardwareInterface Modules OS7-ANI3-U4 OS7-ANI12-U1 • OS7-ANI12-U1 • Single port OC-12c/STM-4 module • OS7-ANI3-U4 • Four port OC-3c/STM-1 module • LEDs • Standard OK1 and OK2 • Single LED per ATM port (No Link, Link Activity) • Bi-directional, wire-speed operation on all ports • Full line rate on all ports • Interoperates with: • Alcatel’s XOS ATM • Alcatel’s 7670 • Cisco • SONET interfaces supported: • SONET • SDH

  7. HardwareOC3 Optics • OC3-SFP-LX • MOD, XCVR, OPT, SFP, OC-3c/STM-1 (155Mbps), IR, SM, DD, LC, 3.3V • Compliant with SONET / ITU-T and IEEE or FC • SFP transceivers fully compliant w/ SFP-MSA Spec. • OC3-SFP-LH • MOD, XCVR, OPT, SFP, OC-3c/STM-1 (155Mbps), LR-1, SM, DD, LC, 3.3V • Compliant with SONET / ITU-T and IEEE or FC • SFP transceivers fully compliant w/ SFP-MSA Spec.

  8. HardwareOC12 Optics • OC12-SFP-LX • MOD, XCVR, OPT, SFP, OC-12c/STM-4 (622Mbps), IR, SM, DD, LC, 3.3V • Compliant with SONET / ITU-T and IEEE or FC • SFP transceivers fully compliant w/ SFP-MSA Spec. • OC12-SFP-LH • MOD, XCVR, OPT, SFP, OC-12c/STM-4 (622Mbps), LR-1, SM, DD, LC, 3.3V • Compliant with SONET / ITU-T and IEEE or FC • SFP transceivers fully compliant w/ SFP-MSA Spec.

  9. Software FeaturesFunctional Support • ATM software provides the following main functions: • Configuring and deleting ATM PVCs • Configuring encapsulation type on VCs • Configuring ATM service categories on VCs • Administratively enabling/disabling VCs • Collecting cell statistics • Per VC • Configuring applications (services) on a VC • Routing Application Over ATM • Bridging Application Over ATM • Multicast Routing Over ATM

  10. Software FeaturesAAL5 and Virtual Connection • Maximum 48 VCs per ATM blade. • VCs are configured as Routed or Bridged (not both simultaneously) • VPI valid range is 0-255 • VCI valid range is 0-65535 • Maximum 128 VCs per system • Ethernet to ATM integration: • VLAN mapping per VC • Maximum 4K VLANs per VC using 802.1q • Multiple VLANs supported per VC • Single VLAN will span multiple VCs • RFC2684 encapsulation used to support multiple VLANs over a VC • Classes of service supported: • UBR • UBR+ (UBR with MCR)

  11. Software FeaturesServices • RFC2684 “Point to Point” Ethernet bridging and routing (IPv4) • Layer 2 services supported: • STP • 802.1D • 802.1w • 802.1s • UDP relay • Transparently transported GMAP & AMAP (next release) • Layer 3 services supported: • RIP & RIP II • OSFPv2 • IPX • VRRP • IP multicast bridging and IPMS supported: • Multicast routing supported over L2 bridge only • IP multicast routing protocols • DVMRP • PIM-SM

  12. Software FeaturesQoS • ATM OC3/OC12 blades perform QoS for UBR, UBR+ & strict priority traffic • No Traffic Policing or Shaping is implemented in this release • There are 16 queues for UBR+ and one queue for UBR traffic • The classification is based on the 802.1p priority values. • Priority mapping: • 6 & 7 are mapped to Strict priority traffic which get the best QoS treatment • 5 is mapped to UBR+ traffic with a guaranteed rate of (xx) Meg per OC3 port and (xx) Meg per OC12 port • In the presence of UBR+ and strict priority traffic, there is no guaranteed treatment for UBR • Scheduling of priority based queues per port is done using SPWRR (strict priority weighted round robin) scheme.

  13. Software FeaturesManagement • Three management interfaces supported: • Command Line Interface (CLI) • Simple Network Management Protocol (SNMP) • WebView • Text-Based Configuration supported • ATM and packet statistics gathered per VC basis • Cell Statistics (VC only) • 32 bit statistics, can be user cleared • Traps supported

  14. Application ExamplesEthernet Bridging • Two VLANs at different remote sites connected through ATM • ATM PVCs are configured between OS1 and OS2 with bridged LLC/SNAP encapsulation • VCs associated to both VLAN 1 and VLAN 2 • Tagged or untagged packets entering OS1 from VLAN1/2 are switched with layer 2 bridging to ATM • Packets egress with LLC/SNAP encapsulation indicating Ethernet and with any appropriate tags • Packets switched via ATM arriving at OS2 where ANI reassembles packet and de-encapsulates LLC/SNAP • OS2 will bridge packets to interfaces VLAN 1 or VLAN2 as appropriate

  15. Application ExamplesATM to GigE Migration Strategy Building Distribution Bldg. D • Connections • Core - OC12 • Data Center - OC12 • Building Distribution – OC3/OC12 • Servers/User – Ethernet • High availability • Fully meshed • Centralized routing w/backup router • 2 Data centers for disaster recovery • 2 switches per building distribution Bldg. C Bldg. B Bldg. A OmniMSS Main Backup Core Data Center A Data Center B

  16. Main Backup Application ExamplesATM to GigE Migration Strategy – cont. • Create new core • Layer 3 switches • Links to old core via ATM • Still centralized routing but moving toward distributed • Move subnets one at a time Building Distribution Bldg. D • Highly available core • Meshed topology • GigE Links • Link aggregation Bldg. C Bldg. B Bldg. A OmniMSS Core Data Center A Data Center B

  17. Bldg. A Bldg. B Bldg. C Bldg. D Building Distribution Main Backup Core Core Data Center A Data Center B Application ExamplesATM to GigE Migration Strategy – cont. • Migrate data centers • Split routing (Core vs. Data Center) • GigE Links w/Link Aggregation • Servers are GigE • New buildings are installed w/GigE • Given new subnet • Migrate buildings from ATM to GigE • Build parallel distribution layer w/GigE • Give new subnet • Migrated users to new switches • Remove ATM core

  18. Building Distribution Main Backup Core Data Center A Data Center B Application ExamplesATM to GigE Migration Strategy – Final Phase • Turn routing off in core • Uses same switches • Uses same AOS • Architecture • High performance core • Fully meshed high availability • Distributed routing

  19. CompetitiveCisco Pricing All Cisco modules are full service modules with MPLS, LANE services, fixed optics and in one case 4 GigE ports. Single mode is intermediate reach only. OC-3 is multimode

  20. CompetitiveFoundry & Extreme Pricing All Foundry's single mode is fixed short or intermediate reach Extreme supports only OC3 ATM interfaces, single mode is intermediate reach and interfaces are fixed optics

  21. CompetitiveNortel Pricing All Nortel's single mode is intermediate reach

  26. Alcatel Advantage • Maintain or expand existing ATM network and need Ethernet connectivity • 1 of few vendors still producing ATM products • Strong resident ATM knowledge and support • No current plan to EOL legacy ATM portfolio • ATM uplinks developed for latest switch offering • Customers looking to migrate existing ATM network to Ethernet • Can continue to leverage past investment • No forklift migration strategy • Smooth migration with feature continuity (XOS vs. AOS) • Group mobility • User Authentication • Integrated NMS (legacy and new products) • Cost effective migration solution • Especially in high availability configurations • OmniSwitch 7700 ATM offering interoperates with Alcatel’s OmniSwitch, 7670, 7750
