# SRC Client Configuration Overview

The JunosE Software has an embedded client that interacts with the Juniper Networks SRC software, enabling the SRC software to manage the router’s policy and QoS configuration.

The connection between the router and the SRC software uses the Common Open Policy Service (COPS) protocol and is fully compliant with the COPS usage for policy provisioning (COPS-PR) specification. The router’s SRC client functions as the COPS client, or policy enforcement point (PEP). The SRC software functions as the COPS server, or policy decision point (PDP).
