Project: Connectivity Packet Platform (CPP)
Project Description:
CPP is a carrier-class technology that has been positioned for access and transport products in mobile and fixed networks. It is an execution and transport platform with customized interfaces for application design. The execution provides support for the design of application hardware and software. The transport part, seen as an internal application on the execution platform, consists of various protocol support, signaling, and ET transmission. Typical deployments of CPP include third-generation (3G) nodes—RBSs, RNCs, media gateways, and packet data service nodes.
