ServiceRegistry¶

//
// Models the functionalities of the Service Registry entity in
// the MEC architecture (ETSI GS MEC 003). It exposes a REST API
// compliant with ETSI GS MEC 011, allowing MEC applications to discover MEC services
// available in the MEC host. In particular, MEC applications can obtain the IP address
// and port number for each instantiated MEC service, so that they can start sending
// requests to it
//
simple ServiceRegistry like IApp
