SERVICES: WAN CONNECTIVITY
|
WAN Connectivity
Networks can be characterized in terms of spatial distance as local area networks
(LAN a basic dealer network), and wide area networks (WAN connecting multiple dealers
together). WAN connectivity refers to the Telecom services (technologies) used to
connect the remote networks.
Application e.g.: Dealers with multiple lots that need to share secure data, accounting,
or dealer management systems.
Types (Speeds/Flavors)
• Frame Relay; sites: 3 - and up
Frame relay is a telecommunication service designed for cost-efficient data transmission
for intermittent traffic between local area networks (LANs) and between end-points in a
wide area network (WAN). For most services, the network provides a permanent virtual
circuit (PVC), which means that the customer sees a continuous, dedicated connection
without having to pay for a full-time leased line, while the service provider figures out
the route each frame travels to its destination and can charge based on usage. A customer
(Dealer) can select a level of service quality - prioritizing some frames and making
others less important. Frame relay is offered by a number of service providers, and you
have access to competitive quotes form multiple carriers in this program. Frame relay can
be provided in varying speeds to meet specific requirements.
•IP VPN; sites: 2 - and up
A virtual private network (VPN) is a private data network that makes use of the public
telecommunication infrastructure, maintaining privacy through the use of a tunneling
protocol and security procedures. A virtual private network can be contrasted with a system
of owned or leased lines that can only be used by one company. The idea of the VPN is to
give the company the same capabilities at much lower cost by using the shared public
infrastructure rather than a private one. Companies today are looking at using a private
virtual network for both extranets and wide-area intranets. Using a virtual private network
involves encrypting data before sending it through the public network and decrypting it at
the receiving end. VPN is offered by a number of service providers, and you have access to
competitive quotes form multiple carriers in this program.
•Point-to-Point; users: 2 - only
A dedicated lease line or Point-to-Point WAN connection is a system of owned or leased
lines that can only be used by one company. This network technology is manly utilized
when only two locations require access to each other's data.
