IEEE 802.1CF-2019 PDF
This recommended practice specifies an access network (which connects terminals to their access routers) utilizing technologies based on the family of IEEE 802 standards. An access network reference model (NRM) that includes entities and reference points along with behavioral and functional descriptions of communications among those entities is provided in this recommended practice.
Heterogeneous networks may include multiple network interfaces, multiple network access technologies, and multiple network subscriptions. In some cases such heterogeneous functionality must be supported in a single user terminal. This recommended practice supports the design and deployment of access networks based on IEEE 802 technologies, guides the developers of extensions to the existing standards in support of a heterogeneous access network, and enables the use of IEEE 802 standards in new network deployments by specifying the functions of the IEEE 802 technologies when deployed in access networks.
New IEEE Standard – Active. An access network (which connects terminals to their access routers) utilizing technologies based on the family of IEEE 802(R) standards is specified in this recommended practice. An access network reference model (NRM) that includes entities and reference points along with behavioral and functional descriptions of communications among those entities is provided in this recommended practice.
