User`s manual

UDP, like TCP, uses IP for delivery; however, unlike TCP, UDP provides for exchange of
datagrams without acknowledgments or guaranteed delivery. Best suited for small, independent
requests, such as requesting a MIB value from an SNMP agent, in which first setting up a
connection would take more time than sending the data.
UNI signaling
User Network Interface signaling for ATM communications.
Virtual Connection (VC)
A link that seems and behaves like a dedicated point-to-point line or a system that delivers packets
in sequence, as happens on an actual point-to-point network. In reality, the data is delivered
across a network via the most appropriate route. The sending and receiving devices do not have
to be aware of the options and the route is chosen only when a message is sent. There is no
pre-arrangement, so each virtual connection exists only for the duration of that one transmission.
WAN
Wide area network - A data communications network that spans any distance and is usually
provided by a public carrier (such as a telephone company or service provider).
Appendix B Cabling / Connection
