frastructure to man- age the virtualized resources. The ME reference architecture shown in Fig. 1.48 incorporates the following reference points [46]: Mp1 is a reference point between the ME platform and the ME applications that pro- vides service registration, service discovery, and communication support for services. It also enables other functionalities such as application availability, session state relocation support procedures, traffic rules and DNS rules activation, access to persistent storage and ToD information, etc. 5G Network Architecture 107 Mp2 is a reference point between the ME platform and the data plane of the virtualiza- tion infrastructure and is used to instruct the data plane on how to route traffic among applications, networks, services, etc. Mp3 is a reference point between the ME platforms and is used for controlling commu- nication between ME platforms. Reference points related to the ME management Mm1 is a reference point between the ME orchestrator and the OSS that is used for trig- gering the instantiation and the termination of ME applications in the ME system. Mm2 is a reference point between the OSS and the ME platform manager that is used for the ME platform configuration, fault detection, and performance management. Mm3 is a reference point between the ME orchestrator and the ME platform manager and is used for the management of the application life cycle, application rules and requirements, and keeping track of available ME services. Mm4 is a reference point between the ME orchestrator and the VIM which is used to manage virtualized resources of the ME host including maintaining track of available resource capacity and managing application images. Mm5 is a reference point between the ME platform manager and the ME platform and is used to perform platform configuration, configuration of the application rules and requirements, application life cycle support procedures, management of application relo- cation, etc. Mm6 is a reference point between the ME platform manager and the VIM
