Agenda > MLS Standards & Technologies > CA Spectrum & CA ehealth for MLS Management > MLS Services: L3 & L2 VNs In-depth look at VLS > Metro Ethernet 4 October 12, 2009 Managing MLS Networks Copyright 2009 CA

What is MLS? > An acronym for Multi rotocol Label Switching > Originally Another way to forward packets Originally faster Derived from tag switching in the late 90s > Now Large set of IETF standards Defining a converged backbone Supporting a large variety of services Voice, video, data & QoS Some providers phasing out new Frame Relay deployments 5 October 12, 2009 Managing MLS Networks Copyright 2009 CA

MLS It s about the Services > Layer 3 VNs RFC 2547 Offers I Service to enterprise customers Replacement for Frame Relay & ATM > Layer 2 VNs seudowire Virtual rivate LAN Service (VLS) 10 October 12, 2009 Managing MLS Networks Copyright 2009 CA

CA Spectrum Infrastructure Manager & CA ehealth erformance Manager MLS Management

New in CA Spectrum r9.2 > Integrated Core Spectrum and Network Services Auto Discovery Selective I Range Selective Technology: MLS, L3 VNs, VLS > MLS L3 VN Membership (display and grouping) based on Route Distinguisher (RD) > VN Manager VRF Discovery Filter: Include / Exclude > VLS Manager (for Juniper devices) > BG Internal eer Session Monitoring > Support for Overlapping VNs (GA is targeted for r9.2.1) 22 October 12, 2009 Managing MLS Networks Copyright 2009 CA

CA Spectrum Features Under Consideration ost r9.2.0 > MLS Transport Manager Service Assurance: LS ing & LS Trace Support for MLS Fast ReRoute Group Forward & Return LSs (into bidirectional pairs) Management of non-traffic Engineered Environments > VN Manager Support for Hub & Spoke VN Topology QoS Aware Service Assurance Tests > VLS Manager Support for Cisco devices Service Assurance Tests 23 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Managing MLS with CA ehealth > Reporting on LS segments - many available At-a-Glance Trend Top N > Context launching from Spectrum into CA ehealth r10.0 > MLS segment discovery enabled by: EH_DISCOVER_CISCO_MLS 24 October 12, 2009 Managing MLS Networks Copyright 2009 CA

MLS Services L2 & L3 VNs

CA Spectrum L3 VN Service Monitoring > VN status Router status Interface status hysical & logical > Threshold alarms based on % of sites down 28 October 12, 2009 Managing MLS Networks Copyright 2009 CA

VN Service Infrastructure Health VN Service 1 of 3 Sites Down VN Site Infrastructure or or ort Connecting VN Customer Disabled VN Via Config Change 32 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Service Assurance Testing VN-Green Site VRF ing MLS roviders Core Network Site Site VN-Green VN-Red VN-Red Site Boston London aris Site VN-Blue VN-Green Site Site VN-Blue 33 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Benefits of Using VRF Traceroute > Instant access to troubleshooting tools. No need to telnet to device (passwords) > oll LS path for all sites to detect change Alert on excessive path change (one time event) Alert on excessive path change over time (event rule) > ath history for troubleshooting What is the current path? Is this typical? What was the previous path? Does this path change often? 39 October 12, 2009 Managing MLS Networks Copyright 2009 CA

VLS: How it works > rovider assigns a customer one (or more) VFI(s) > rovider assigns interfaces to a VFI > rovider s infrastructure appear like a big virtual switch Forwards Ethernet frames out proper port Floods unknown frames out all virtual switch ports Loop prevention MAC addresses learning MAC address aging 41 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Advantages of VLS over L3 VNs > Simpler connection to provider Ethernet available > otentially lower cost device > Enterprise retains control of routing > Logical migration step from Frame Relay > Advantages benefit enterprise > Which one should you use? 42 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Advantages of VLS over 2 VNs > For the enterprise Naturally full mesh Manage only single link to provider Not N^2 separate tunnels > For the provider Ease of setup define VFI / associate interfaces Single connection to enterprise site 43 October 12, 2009 Managing MLS Networks Copyright 2009 CA

National L2 vs. L3 Availability in US > L2 ATT (most markets) Level 3 / Broadwing Masergy Time Warner Telecom Verizon Yipes Denise appalardo - Network World 4/26/07 > L3 ATT Level 3 Qwest Time Warner Sprint XO one Communications ACC Business Verizon Many, many more 44 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Managing L2 VNs with CA ehealth M > seudowire emulation reports available with: CA ehealth 6.0 S4/D4 CA ehealth 5.7 S9/D9 > Context launch from CA Spectrum r10.0 > At-a-Glance reports show: ackets / sec Bytes / sec Availability 48 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Metro Ethernet Basics > A Metropolitan Area Network Service provided to Customers Lower cost yet high speed > A Service rovider Solution Collection of Layer 2 and/or 3 switches/routers connected through optical fiber Topology could be ring, hub & spoke, or full/partial mesh Hierarchy is Core, Distribution (Aggregation) and Access The core in most cases is I/MLS but could also be newer forms of Ethernet transport with 10Gbps or 100Gbps speeds. 50 October 12, 2009 Managing MLS Networks Copyright 2009 CA

What is Driving MetroEthernet? > High Bandwidth Services MultiMedia, Telepresence, ITV, VoD > Need to increase Capacity & reduce Costs > Converged rovider Core to build out services > MetroE romises Simpler low cost connection (Ethernet UNI) Lower cost Device Scalable & Incremental Bandwidth Enterprise retains control of routing Ultimately lower costs 51 October 12, 2009 Managing MLS Networks Copyright 2009 CA

MEF and Vendor Defined Services > E-Line Service (oint to oint) Virtual Leased Line (VLL) Ethernet rivate Wire Service (EWS) or seudowire (W) Ethernet Relay Service (ERS) > E-LAN Service (Multipoint to Multipoint) Virtual rivate LAN Service (VLS) Transparent LAN Services (TLS) Ethernet Multipoint Service (EMS) [Cisco] Ethernet Relay Multipoint Service (ERMS) [Cisco] > E-Tree Service (oint to Multipoint) 52 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Advantages of MLS Metro Ethernet > Scalability ure Ethernet MANs have limit of 4096 VLANs > Resiliency ure Ethernet MANs may take 1 to 30 seconds to converge MLS can converge in 50 msecs > Multi rotocol Convergence With the use of suedowire MLS can backhaul not only I/Ethernet traffic, but virtually any customer traffic like ATM aggregation for UMTS or TDM aggregation for GSM > End to End OAM Wide set of troubleshooting tools like MAC ping, MAC traceroute, LS ing, etc. 53 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Ethernet OAM rotocols These standards are being studied for general ehealth and Spectrum support. Some are already supported in ehealth for the ADVA 5000 device 54 October 12, 2009 Managing MLS Networks Copyright 2009 CA

How Does CA Help Manage Metro Ethernet? > Broadest Range of Device and Vendor Support Cisco, Juniper, Alcatel-Lucent, Adtran, ADVA, Huawai, Nortel, Extreme, Foundry > Technology Support MLS Interfaces, Segments, Tunnels, VLAN, VLS, VN, QOS, seudowire, MLS TE, Multicast, Ethernet, LAN/WAN, Sonet/SDH, DWDM > Device Change & Configuration Management > Layer 2 and 3 Topology Maps (Juniper L2 in Fall) > roactive erformance Management > Correlation and Root Cause Analysis > Automated Grouping and Testing Groups, Group Lists, Global Collections Cisco I-SLA, Juniper RM New Metro Ethernet I-SLA tests being added to ehealth/spectrum > Real Time Service Management Dashboards and Reports > Traffic monitoring (major changes and capabilities planned for the near future) 56 October 12, 2009 Managing MLS Networks Copyright 2009 CA

Summary > MLS Solutions offer a converged backbone" allowing providers to transport voice, video and data services on a single infrastructure offering QoS Typically deployed in provider networks > Many enterprises rely upon MLS-based VN services Layer 3 VNs are widely deployed, with Layer 2 rapidly increasing in popularity > CA offers solutions for MLS management for both providers and enterprises New Metro Ethernet management capabilities are under development 57 October 12, 2009 Managing MLS Networks Copyright 2009 CA
