Methodology - Manage by SLA Measure Definition Mandatory Service Standard Availability Percentage of time that the Offeror’s MPLS VPN Core Network is available for use by GTA and GTA Customers. This is 100 – (outage minutes / monthly minutes). MPLS VPN Core Network outages are defined as a loss of ability to transmit IP packets, packet loss of 1% or more, or latency of 80 ms or greater on the MPLS VPN Core Network. 99. 99% Latency refers to the average time required (delay), in milliseconds, for one-way packet transmission from any Edge Router on the Offeror’s MPLS VPN Core Network to any other Edge Router on the Offeror’s MPLS VPN Core Network. Latency in Access Circuits is not included. 36 ms Jitter refers to the standard deviation of variation in Latency from packet to packet. For the purposes of this SLA, Jitter refers to transmissions across any portion of the Offeror’s MPLS VPN Core Network, excluding Access Circuits. < 5 ms
Methodology Measure Definition Mandatory Service Standard Packet Delivery is the proportion of packets transmitted from a sender that are received by the intended receiver. 99. 5 % Outage Notification Period The Offeror will contact GTA with notification of an outage within the Outage Notification Period for any service affecting outage. 15 minutes
RFP Evaluation • Six proposals submitted • Separate technical and pricing evaluation teams • Teams composed of both Agency and GTA personnel

MPLS Service Overview
Data Network Migration Strategy Current Environment Desired State: Network IP VPN Environment Internet Access Frame Relay, DSL, Private Line Ethernet “Migration Path” Private Lines Frame Relay Internet Access Frame Relay, DSL, Private Line Managed IP Connectivity Services Internet Access Frame Relay, DSL, Private Line Access ATM • Challenges of Current Network – Integrating different networks – Capacity of network is difficult to manage – Cost of multiple WAN connections Frame Relay, DSL, Private Line • Solutions – Enables convergence of voice, video and data – Shifts complexity of network and investments to the provider – Meshed architecture – more efficient routing – Local aggregation
Quality of Service MPLS provides platform to begin deploying voice/video over single network • Reduce long distance costs for voice in the future • Ensure mission-critical traffic gets through network and gets prioritized Critical Data Voice Video Internet Single Infrastructure MPLS Network
Leveraging The Bell. South Regional IP Backbone Attributes: • Dual redundant Internet connections • Regional aggregation • Redundancy (no single point of failure) • Converged infrastructure
Managed MPLS Site-to-Site Service “On-Net” Sites DSL Remote Office – Bell. South or ALLTEL “Off-Net” Sites Headquarters Extranet Partner Router with IPSec Private IP DSL Internet Access thru GTA Firewall Router Branch Office Frame Relay (128 K) Private Line Internet Bell. South MPLS Network Mobile Telecommuter IPSec Gateway DSL, Dial, ISDN or Cable Client with IPSec
GTA Managed DSL Retail DSL • Private network • Managed equipment • Comprehensive SLA • Proactive notification and repair • Network management reports • Secure Internet connection • Public Internet access • Unmanaged equipment • No SLA • Consumer-grade support • No reporting capabilities • Unsecured Internet connection
Managed MPLS On-Net DSL Service When to use DSL (where DSL qualifies): • Lower cost WAN access method for data traffic – no Qo. S required • New applications requiring higher bandwidth • Backup solution for primary site access • For remote users requiring secure Internet & WAN access When not to use DSL: • Sites requiring Quality of Service – Mainframe, Voice, Video, etc. • Applications that do not work well with asymmetric data uploads/download – (take this out or clarify) • When network is near top speed of DSL Service (up or down)
Managed MPLS Site-to-Site Access Options Frame Relay • Lower cost option, multiple bandwidth increments, bandwidth guarantees, Qo. S availability for speeds greater than 768 K Private Line and ATM • Best choice for Qo. S, Private Line is distance sensitive, bandwidths up to OC-3 Metro Ethernet (in Metro areas) • Lower cost host circuit access, multiple VLAN’s for shared agency sites, Qo. S support, available in major metro areas, distance sensitive (from Bell. South Po. P)
Support for Teleworkers • Support for remote telecommuters with private DSL, Internet access via DSL, dial-up, ISDN or cable modem access methods used in the home • Encrypted connectivity to MPLS cloud via GTA Managed IPSec Gateway • Port Speed must be determined to engineer Internet access capacity
SNA Site Access Option 1 – SNA to IP Conversion • Some agencies may be ready or mandated to convert to IP end-to-end • Will require up-front investment in equipment • Traffic will be passed as IP across the MPLS network Option 2 – SNA Encapsulation • SNA will be encapsulated at the Bell. South-provided router using DLSw • The traffic will then be passed as IP across the MPLS network • DLSw peers will exchange SNA traffic directly with the mainframe
Illustration of SNA Encapsulation
Other GTA Managed MPLS Service Features GTA Project Management, Vendor Coordination, Billing/Ordering, Management Services • Real-time monitoring, management and maintenance of Routers • New CPE provided at each site for initial installation • Full configuration management • SLA’s and network management reports • GTA has streamlined support for CPE and transport – GTA has contracted service levels and reduced number of suppliers
