cell
An ATM Layer protocol data-unit (PDU), characterized by fixed-length rather
than variable-length payloads. The standard ATM cell is 48 bytes of payload
with 5 bytes of header.
cell relay
See
ATM
.
client
A single-user computer that requests application or network services from a
server.
client-server
A distributed system model of computing that brings computing power to
the desktop, where users (“clients”) access resources from servers.
CLP
Cell loss priority. A bit in the ATM cell header indicating a need to discard
the cell.
community string
A character string included in each SNMP protocol message sent between
external management applications, such as between Transcend® Enterprise
Manager software and the LANplex system.
connection
An ATM connection consists of the concatenation of ATM Layer links in
order to provide an end-to-end information transfer capability to access
points.
connectionless
communications
A form of packet switching that relies on global addresses in each packet
rather than on predefined virtual circuits. Ethernet, FDDI, and token ring are
connectionless.
connection-oriented
communications
A form of packet switching that requires a predefined circuit from source to
destination to be established before data can be transferred.
concentrator
An FDDI station having additional PHY/PMD entities beyond those required
for its own attachment to an FDDI network. These additional PHY/PMD
entities, called M (master) ports, are for the attachment of other FDDI
stations (including other concentrators) in a tree topology.
DAC
Dual attachment concentrator. A concentrator that offers two attachments
to the FDDI network that are capable of accommodating a dual, counter-
rotating ring. A DAC contains an A-B port pair and at least one M port.
