Re: Frame-relay connectionless ?

You calling me a freek??? ;-)
The connectionless mode is message-oriented and supports data transfer in
self-contained units with no logical relationship required between units.
Because there is no acknowledgement of each data unit transmission, this
service mode can be unreliable in the most general case. However, a specific
provider can provide assurance that messages will not be lost, duplicated,
or reordered.

The acknowledged connectionless mode provides the means by which a data link
user can send data and request the return of data at the same time. Although
the exchange service is connectionless, in-sequence delivery is guaranteed
for data sent by the initiating station. The data unit transfer is
point-to-point.
