- Active. This bundle describes heterogeneous networks convergence and scalability, specifies the requirements of network convergence, extends the system architecture defined in IEEE Std 1888(TM). It enables IEEE 1888 systems to interoperate with heterogeneous access networks efficiently and improves the efficiency, flexibility, scalability and manageability of IEEE 1888 systems. It enhances security management function for the protocol defined in IEEE 1888(TM). It provides security requirements, system security architecture definitions, and a standardized description of authentication and authorization, along with security procedures and protocols, are specified. This can help avoid unintended data disclosure to the public and unauthorized access to resources, while providing enhanced integrity and confidentiality of transmitted data in the ubiquitous green community control network. This bundle includes: IEEE Std 1888-2014, IEEE Std 1888.1-2013, IEEE Std 1888.2-2014, IEEE Std 1888.3-2013, and IEEE Std 1888.4-2016.
