Glossary

APA

The Auto Port Aggregation(APA)

product offered by HP allows

grouping

networking

links to form a single high

bandwidth,

highly available and scalable

networking

link, called an aggregate

interface.

HP APA also allows

formation

a failover

group of

networking

links

connected across

switches

for an

highly

available

link

configuration

on the server.

Callee

The DLS user in connection mode

that processes requests for connections from

other DLS users.

Caller

The DLS user in connection mode

that initiates the establishment of a data

link connection.

Communication endpoint

The local

communication channel between a DLS user

and DLS provider.

Connection establishment

The phase in

connection mode that enables two DLS users

to create a data link connections between

them.

Connectionless mode

A mode of transfer

in which data is passed from one user to

another in self-contained units with no

logical relationship required among the

units.

Connection mode

A circuit-oriented mode

of transfer in which data is passed from one

user to another over an established

connection in a sequenced manner.

Connection release

The phase in

connection mode that terminates a

previously established data link connection.

Data link service data

unit

A grouping of DLS user data whose

boundaries are preserved from one end of a

data link connection to the other.

Data transfer

The phase in connection and

connectionless mode that supports the

transfer of data between two DLS users.

DLSAP

A point at which a DLS user

attached itself to a DLS provider to access

data link services.

DLSAP address

An identifier used to

differentiate and locate specific DLS user

access points to a DLS provider.

DLS provider

The data link layer protocol

that provides the services of the Data Link

Provider Interface.

DLS user

The user-level application or

user-level or kernel-level protocol that

accessess the services of the data link layer.

Local management

The phase in

connection and connectionless modes in

which a DLS user initiates a stream and

binds a DLSAP to the stream. Primitives in

this phase generate local operations only.

PPA

The point at which a system attaches

itself to a physical communications medium.

PPA identifier

An identifier of a particular

physical medium over which communication

transpires.
