3 Traditional WAN Solutions

4 The Case for Change: Its Complicated and Expensive for Both of Us Historically… –Separate edge and core networks built for each service offering –Services and networks that address single applications well but do not individually address a broad range of customer needs –Individually highly scalable, robust and stable network platforms Forcing Customers to… –Invest time, money and resources into different platforms –Purchase disparate networks based on service need –Perform network integration and their own access aggregation –Split applications based on networking capabilities –Prioritize investments across applications We never met a network we didnt like… DSL DIA GigE Voice Frame Relay ATM/ Frame Relay Internet

5 Solutions –Management simplification – one platform –Enables network and applications convergence –Shifts complexity/investments to the provider –Connectionless architecture – more efficient –Inter-LATA, limitless reach Challenges –Integrating disparate networks –Managing disparate networks –Capacity planning, extending connectivity –Costly, complex CPE –Multiple WAN connections cost and complexity Data Network Migration Strategy Desired State: Network IP VPN Environment Managed IP Connectivity Services ATM Private Lines Frame Relay Current Environment Internet Access Ethernet Internet Access Access Frame Relay, DSL, Private Line Access Frame Relay, DSL, Private Line Access Frame Relay, DSL, Private Line Access Frame Relay, DSL, Private Line Migration Path Internet Access

6 Evolving Network Solutions Private Line High performance High security Frame Relay/ATM Lower cost Improved scalability Quality of service High performance High security MPLS IP VPN Class of Service for IP Simplified connectivity (easy any-to-any connectivity) Simplified addressing Simplified network topology Simplified L2 and L3 administration Increased flexibility (more access options) IP-based network recovery Simple migration from Frame Relay Lower cost Improved scalability Quality of service High performance High security Functionality Time MPLS IP VPNs build upon traditional Layer 2 technologies, promising a higher order of service capabilities Market Assessment

7 VPN Overview

8 A VPN By Any Other Name… ATM Frame Relay Managed Network VPN Service –MPLS/BGP (RFC 2547) Routers Firewalls VPN Concentrators IPSec Client Software VPN Types Network Based VPNs CPE Based VPNs (IPSec) Layer 2 VPNs (Point-to-Point) Layer 3 (IP-VPNs)

9 IP VPN Models – CPE vs. Network First Generation IP VPN network Implemented over the public Internet Security is provided via IPSec Can be difficult to scale May require expensive CPE Difficult to control QoS Next Generation MPLS network Implemented over a private IP backbone Intelligence resides in the cloud Provides Any-to-Any connectivity Designed for converged IP services Provides QoS/CoS capabilities IP Partitioning/Tunnel Branches Headquarters IP Tunnel Branches Headquarters Network-based VPN CPE-based VPN Internet CarriersBackbone

10 Network VPN Drivers CapabilityCustomer Needs Secure WAN Connectivity Cost-effective WAN connectivity for branch offices & business partners Access options Nationwide coverage Remote User Connectivity Secure connectivity for remote users Cost-effective end-user helpdesk Secure Internet access for remote users Ubiquitous coverage Internet Access Secure Internet access for all sites/users Single, integrated solution from one provider Segmentation of private WAN traffic from Internet traffic Network Management Performance Guarantees Network performance reports User administration tools

11 MPLS Overview

12 What is MPLS? Multiprotocol Label Switching A standard for switching packets over an IP Network using labels or tags that contain forwarding information attached to IP packets LSR = Label Switch Router PE = Provider Edge Device CE = Customer Edge Device VRF = Virtual Route Forwarding MPLS Core Network LSR PE CE VRF LSR VRF How Does It Work? Combines the security and reliability of traditional Layer 2 services (i.e. frame relay, ATM) with the efficiencies of IP networking Forwards packets based on labels Packets are switched, not routed Labels represent destination and may carry service attributes (CoS, Privacy-VPNs, traffic engineering)

13 What Does MPLS Provide? CapabilityMPLS Provides Secure WAN Connectivity MPLS securely segments traffic using customer specific labels to ensure that traffic is not visible to other customers or across the public Internet Outsourcing of complexity MPLS moves routing decisions away from CPE to the provider network allowing for any-to-any configurations without complex and potentially expensive CPE ScalabilityMPLS is scaleable, supporting thousands of VPNs Building block for converged services MPLS is designed to transport a variety of application types, i.e. VoIP, Video over IP, , SAP, etc.

36 Back-up Materials

37 Cost and complexity typically result in less than optimal network topologies (i.e. hub and spoke with multiple PVCs, overbuilt hubs, costly NNI arrangements) Potential bottlenecks and single points of failure Responsibility for functional integration and network management typically falls on the customer –Does not address remote access needs –Access aggregation and integration further increases cost and complexity Traditional Approach Using Frame Relay Desired StateTypical Deployment

38 Who Benefits from the BellSouth Managed Network VPN Service? Organizations that need wide area connectivity Organizations seeking cost-effective backup/disaster recovery solutions for their existing legacy WANs Organizations forming extranets with highly dynamic and meshed network traffic requirements Organizations with strong telecommuting initiatives Organizations deploying new IP-based applications: –Supply Chain Management (SCM) –Enterprise Resource Planning (ERP) –Customer Relationship Management (CRM)
