Glossary
ASP Application Server Process. A process instance of an Remote Application Server
(RAS). An ASP serves as an active or backup process of an Application Server (for
example, part of a distributed virtual switch or database). Examples of ASPs are
processes (or process instances) of MGCs, IP SCPs or IP HLRs. An ASP contains an
SCTP endpoint and may be configured to process signaling traffic within more than
one Application Server.

RAS Remote Application Server. A logical entity serving a specific Routing Key. An example
of a RAS is a virtual switch element handling all call processing for a unique range of
PSTN trunks, identified by an SS7 SIO/DPC/OPC/CIC_range. Another example is a
virtual database element, handling all HLR transactions for a particular SS7 DPC/OPC/
SCCP_SSN combination. The RAS contains a set of one or more unique Application
Server Processes (ASPs), of which one or more is normally actively processing traffic.
Note that there is a 1:1 relationship between an RAS and a Routing Key.
