Benefits of Frame Relay
• Efficient for hub-and-spoke configurations with
stable traffic patterns
• Ubiquity -- ability to interconnect local, national,
international networks
• Mature technology with solid track record and
experience
• Experienced personnel plentiful in work force
• Support of multiple Layer 3 protocols
Background - Changing requirements
•Increased Bandwidth
•Support for large file transfers
–Tax information

Background - Why Change?
The state needs to move to a network that is:
• More robust
• Flexible
• Redundant
• Capable of combining video, voice, and data
• Reduce the State’s overall communication cost
• Provide increased services without increasing current
costs.
MPLS Overview
“The planned MPLS VPN should serve the agency
business requirements for more bandwidth for
business-critical applications, provide the foundation
for secure data, video, and voice communications,
provide a more reliable and more flexible core
network, and, in many cases, provide network access
that is far more economical than is presently available,
especially for smaller government offices.”

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
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
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.

• 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

Managed MPLS On-Net DSL Service
When to use DSL (where DSL qualifies):
• Lower cost WAN access method for data traffic – no QoS 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, QoS availability for speeds greater
than 768K
Private Line and ATM
• Best choice for QoS, 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, QoS support, available in major metro areas,
distance sensitive (from BellSouth PoP)
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 BellSouth-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

Team
• Conduct site surveys
• Schedule site conversions
• Test and approve each site conversion
• Notify billing and network operations after
completion of each site conversion
MPLS Agency Conversion Plan
Scheduling:
• Business Considerations
• Each agency will have its own conversion schedule
• There will be multiple agency implementations
being managed at the same time
• There will be up to 200 site conversions per month
• GTA will be the pilot
MPLS Agency Conversion Plan
To ensure successful conversion of
agency sites:
• Conduct physical site survey (see handout)
• Confirm minimum requirements
• Notify agencies of suggested upgrades
MPLS Agency Conversion Plan
Once a Collaborative Network Design is
Agreed Upon:
• GTA will submit orders to BellSouth
• BellSouth will confirm due dates for site
conversions to GTA
• GTA will coordinate a kick-off meeting with
each agency
MPLS Agency Conversion Plan (each
individual site)
GTA will work with you to coordinate:
• Circuit installation (BellSouth)
• Router installation and testing (BellSouth)
• LAN cutover to MPLS and testing of agency
applications (GTA, BellSouth and Agency)
MPLS Agency Conversion Plan
(Post MPLS Conversion)
• Current Frame Relay services will be
discontinued
• Current Frame Relay Routers will be
decommissioned

migration phase
• Scheduling done through current BellSouth/GSAMS tool
Video Site Scenarios (cont.)
Video over DSL–
Not Recommended for Quality Videoconferencing
• Engineered services available– 192X192, 384X384, 768X512
• DSL is a best effort service
• Only video should traverse the connection – no mixed traffic
• No help desk support if quality of service degrades over DSL
connection – i.e. latency, jitter, packet loss
• No SLA’s for quality of service attributes
