FastFrame
is the high speed service at 64Kbps
and above which ADC "DataNet"
is the first network service provider
in Thailand who has employed the
intelligent Frame Relay technology.
FastFrame has a brilliant high
speed performance that offers
bandwidth on demand to meet each
endpoint's requirement, more security,
reduce mesh network compare to
leased line multiple point, and
increase high efficiency of data
communication over ATM Backbone.

Relay eliminates error correction
function to the intelligent devices
like Router/FRAD at the endpoints,
resulting in significantly faster
data transmission. In contrast
to X.25 that has higher overheads
in end-to-end error recovery. |

| Bandwidth
On Demand |
|
| Unlike
other data communication technologies,
FastFrame users have the unique
advantage to select bandwidth
(ranging from 4 Kbps-2Mbps) dependent
on operational need of the Network.
This results in cost efficiency
by not having to use the same
speed for each connection. |
|
| What
Is CIR? |
|
FastFrame use the capability of Frame Relay to enable to the network managers to determine Bandwidth on demand by using CIR (Committed Information Rate) as a means of selecting the right access rate and CIR for data traffic required by the site's applications.
CIR is the data rate at which the network guarantees throughput in bits per second under Normal network conditions. When traffic is clear, data transmission is automatically channeled to a bandwidth higher than that prescribed by the user. |

PVC |

FastFrame
PVC is a Permanent Virtual Circuit
that needs to define a connection
between Host site and Terminal
site in a network. A Data Link
Connection Identifier (DLCI) specifies
The number of frames in the transmission
process to ensure that data transfer
capability is flawless.
Typically, a FastFrame PVC provides
connectivity between Host and
Terminal in two ways :
Multiple
Site set up with a Frame
Relay Port consisting of many
virtual circuits connected to
many endpoints.
Single
Site set up with a Frame
Relay Port with one virtual circuit
connected to a single endpoint.
FastFrame
PVC for "Frequent and Regular"
Usage
FastFrame PVC is suitable for
corporate businesses with LAN
interconnected to WAN that has
"frequent and regular"
usage of data communication.
