Cisco Service Advertisement Framework (SAF) provides a framework that allows applications to discover the existence, IP address, port, and configuration of networked resources. Cisco SAF allows a timely and reliable awareness of the services within networks, as applications advertise and discover services on networks. Service information distributes though a network of Cisco SAF cooperative nodes that assume specific functions to efficiently distribute knowledge of services and facilitate their discovery. This course describes SAF and the components it comprises and explains the roles of the SAF client and SAF forwarder. The common issues that relate to the SAF client and the SAF forwarder, as well as their potential causes, are also described.
The Call Control Discovery (CCD) feature leverages the SAF network service, a proprietary Cisco service, to facilitate dynamic provisioning of intercall agent information. By adopting the SAF network service, the CCD feature allows Cisco Unified Communications Manager to advertise itself along with other key attributes, such as directory number patterns that are configured in Cisco Unified Communications Manager Administration. As a result, other call control entities that also use the SAF network can use the advertised information to dynamically configure and adapt their routing behaviors. This course describes the CCD service and its components, as well as CCD operation. The common issues of CCD and the causes of these issues are also covered.
