  2. Content • Business Drivers/Common Business Challenges • Level 3 VPN Service Suite/Service Overview • Access and Availability • Service Options/Port Type/CDR • Pricing Options/Overview • Class of Service • SLAs and Customer Portal • Why Level 3?

  3. MPLS VPN Business Drivers • Any-to-any (point-to-point to full mesh) connectivity for maximum performance and efficiency • Common access circuit can share multiple network services for greater value • Nationwide availability, intra- and inter-metro connectivity • Wide range of transport speeds and access methods • Secure network services • Dedicated MPLS Core for VPN services offers strict customer network isolation • Flexibility to grow with the requirements of customer’s business • Scalable technology that simplifies adding/removing sites • Flexible billing options • Flat and usage-based monthly billing • Flexible and granular bandwidth allocation per port • Application-based Class of Service with deterministic traffic handling • Quality of Service SLAs guarantee performance for new and existing applications

  4. MPLS VPN Service Suite Overview • Level 3 offers VPN services that provide any-to-any (point-to-point to full mesh) Ethernet or IP WAN connectivity across a robust and scalable MPLS core network • IP Virtual Private Network (IP VPN) • Virtual Private Line Service (VPLS) • Ethernet Virtual Private Line (EVPL) • The Level 3 VPN network • Connectivity across the U.S. • Highly scalable to meet customer growth requirements • Diverse routing across the backbone to prevent network disruptions • Range of bandwidth options: 1 Mbps through 1 Gbps • Range of access methods • TDM Private Line (DS1, NxDS1, DS3, NxDS3, OC3, OC12) • Ethernet (Fast Ethernet and Gigabit Ethernet, Managed Ethernet Access) • On-net Service Level Agreements (SLAs) • Packet loss, latency, and network availability guarantees

  5. VPN Service Application Mapping Point-to-Point Simple Private Line “type” service • EVPL at Layer 2 is ideally suited for point-to-point or point-to-multipoint applications • IP VPN at Layer 3and VPLS at Layer 2 are ideally suited to support multipoint networks requiring full-mesh capability Hub and Spoke topology obtained by combining multiple point-to-point connections at a central hub location Point-to-Multipoint Multipoint Fully meshing point-to-point connections at scale

  6. MPLS IP VPN Overview • Network-based Layer 3 IP VPN service that provides any-to-any IP transport to enable WAN interconnection across an MPLS core network • RFC 2547bis (BGP/MPLS VPN) • RFC 4364 (obsoletes 2547) • De facto standard for customer VPNs, full-mesh connectivity with CoS/QoS differentiation • Level 3-managed WAN routing for customer simplicity • Both public and private IP addressing supported • Accommodates multiple routing protocols, including: Static, BGP, OSPF, and RIP • Specifically optimized for IP traffic

  7. VPLS Overview • VPLS is an Ethernet-based, any-to-any (fully meshed) data communication service supported over an MPLS infrastructure • RFC 4761 • Allows geographically dispersed customer sites to securely communicate among each other by sharing a single Ethernet broadcast domain • Unlike Layer 3 IP VPNs, Layer 2 VPLS allows customers to maintain end-to-end control and security of WAN routing decisions • No need to exchange routing information with carrier • Customers may use whatever WAN routing protocol (TCP/IP, RIPv2, OSPF, BGP, EIGRP) and addressing schemes they prefer • Combines the control features of Frame Relay/ATM (any protocol, network routing management) with the performance and flexibility of MPLS (full mesh, QoS, scalability) for a truly unique WAN service

  8. VPN Product Positioning

  9. Seattle Boston New York Chicago Philadelphia Newark Pittsburgh Washington DC Cincinnati Denver San Jose St. Louis Los Angeles Phoenix Atlanta Dallas Orlando Houston Access and Availability – VPN Footprint • Coverage across 100% of the U.S. via on-net or off-net access solutions • Level 3 VPN solutions leverage our facilities-based metro networks in the U.S. • On-net Private Line access in approximately 116 markets • On-net Ethernet access in approximately 60 markets • Off-net connectivity to Level 3 is also available throughout the U.S. • Off-net Ethernet in numerous markets through several different carriers • Level 3 VPN network consists of Gateways located in 18 major markets across the U.S.

  11. VPN Class of Service Class of Service (CoS) MPLS provides a connectionless, full-mesh VPN Traffic flows are not fully predictable, so traffic classification ensures data may be identified as to its relative importance Generally defined by customer devices prior to entering the WAN Quality of Service (QoS) Ensuring high-priority traffic receives better service than lower-priority traffic Guaranteed performance varies around latency, jitter, and packet loss Level 3 VPN solutions ensure QoS across our core MPLS network CoS enables QoS Level 3 VPN solutions offer actual QoS guarantees through industry-leading CoS functionality Flexible CoS capabilities to suit your needs

  12. VPN CoS Types • Level 3 enables customers to leverage up to six different CoS categories to help them differentiate their traffic • We then provide the backbone predictability, or QoS, via four distinct queues – illustrated by the banded rows above

  13. Ingress – Customer defines traffic classification Egress – Level 3 prioritizes traffic to ensure QoS Managing CoS – Static and Dynamic • Options for managing Class of Service • Static assignment based on logical interface (EVPL, VPLS, and IP VPN supported) • Logical Interface-Based – Logical interfaces (EVC, VLAN, or DLCI) are mapped to the appropriate traffic classes regardless of DSCP or P-bit markings • Dynamic assignment inferred by customer DSCP (for IP VPN) or 802.1p (for VPLS) markings • Traffic classes inferred by customer IP DSCP or 802.1p markings • Level 3 will not overwrite IP precedence/DSCP bits for IP VPN service • Percentage bandwidth allocation required

  16. VPN Configuration Options • Wide array of VPN port types, encapsulation methods, CDR, and CoS options to suit your varied requirements

  17. Service Level Agreements • More than just Class of Service functionality – actual Quality of Service guarantees 1– Site Specific (excluding off-net components) 2 – Core Network Average

  18. IP VPN/VPLS Pricing Components C-Loc Access Level 3 POP Level 3 POP CoS BW C-Loc Port Level 3 MPLS Network A-Loc Access CoS BW CoS BW B-Loc Access A-Loc Port B-Loc Port Any-to-Any VPLS or IP VPN Solution • IP VPN/VPLS pricing is based on three primary components • Access: On-net or off-net, TDM or Ethernet, or cross-connect • VPN Port: Defined by Access port chosen • Logical Interface(s): Choose CoS and CDR for each logical Interface • Additional pricing components may include MEA and/or ENS services • If Access type is MEA, VPN port pricing may vary

  19. EVPL Pricing Components Level 3 POP Level 3 POP Level 3 MPLS Network A-Loc Access B-Loc Access B-Loc Port A-Loc Port Logical Interface (distance-based pricing) Point-Point or Point-to-Multipoint EVPL Solution • EVPL pricing is based on three primary components • Access: On-net/off-net Ethernet, MEA, or cross-connect • VPN Port: Defined by Access port chosen • Logical Interface(s): Choose CoS and CDR for each logical interface • The Logical Interface price is distance-based; the distance determines a mileage band factor to be applied • The distance (for the mileage band factor) is calculated between endpoints where Access connections terminate • Additional pricing components may include MEA and/or ENS services • If Access type is MEA, VPN port pricing may vary

  20. Key Benefits of New Converged VPN Service Platform • VPN service attributes aligned as much as possible • Access options • VPN port options • Bandwidth options • CoS (Class of Service) options • CoS allocation types (Static and Dynamic) • Billing options and pricing methodology (fixed and usage/CDR) • Common network architecture (Juniper) enables consistent feature/functionality, including ability to provide all three VPN services over the same VPN port • Common order management system (Pipeline) streamlines order entry and provisioning processes, further mitigating backlog issues experienced in 2007
