-# pvAccessCPP: ca provider
-
-2018.10.05
-
-Editors:
-
-* Marty Kraimer
-
-**ca** is a channel provider **ca** that is implemented as part of **pvAccessCPP**.
-
-
-It uses the **channel access** network protocol to communicate with a server,
-i. e. the network protocol that has been used to communicate with **EPICS IOCs** since 1990.
-
-A description of **ca** is provided in
-[caProvider](https://mrkraimer.github.io/website/caProvider/caProvider.html)
-
-Provider **pva** is another way to connect to a **DBRecord**,
-But this only works if the IOC has **qsrv** installed.
-**qsrv**, which is provided with
-[pva2pva](https://github.com/epics-base/pva2pva),
-has full support for communicating with a **DBRecord**.
-The only advantage of **ca** is that it does require any changes to an existing IOC.
