raphs describe some common platform component capabilities used in an all-IP network, two examples platforms that integrate common components, and some examples of customer services. The component and capa- bilities include directories, public key encryption, signaling protocols, gateways, communication Building the Network of the Future optimizations, and policy rules and enforcement. The platform examples include the 3GPP IMS and a content delivery network (CDN). While the network was the service, the method for finding an end point was to assign unique numbers to physical end points, provide some level of assurance that the end-to-end physical con- nection was secure, have the end user or device find and remember unique numbers they wanted to connect with, and involve the end user to verify the identity of the other side of the connection. As technologies such as IP protocols and mobile computing devices became available, a better method was required given the diverse range of services expanding number of end points and identities. Two major classes of technologies support finding and trusting an end point-directories and public key encryption. In modern IP network services, directories are used at multiple levels such as to translate invariant, global unique identifiers to a current IP address, to find the next hop to move a packet destined for a particular IP address toward the destination, and to represent the current devices that are registered and available for a particular type of real-time communications session. Directories may also include rich information about the end point of a connection that assists in the selection and insures the connection is secure. Public key encryption relies on a key pair, one pub- licly advertised (in directories or other sharing mechanisms) and one held securely by a connection end point. One side of a communicating link between end points, can encrypt information using the public key and the other can decrypt it using the private key. This technique along with a trust h
