A metropolitan area network (MAN) is a computer network that is larger than a single building local area network (LAN) but is located in a single geographic area that is smaller than a wide area network (WAN). Generally, it is several LANs interconnected by dedicated backbone connections. It may also refer to public use networking infrastructure in a municipality or region.
A metropolitan area network traditionally refers to a private data network used by a single organization in several buildings or by several organizations interconnected in the same geographic vicinity. It is larger than a LAN in a single building but not large enough to be considered a WAN. The size usually ranges from 5 kilometers to 50 km. If all the buildings are on a single piece of contiguous property, it may also be considered a campus network.

The primary advantage of a MAN over a WAN is the high bandwidth enabled by the dedicated links of a metropolitan area network. This application of a MAN provides higher speed, from 1 gigabit per second to 100 Gbps, and lower latency than would be possible over a WAN. Since the organization maintains control of the connection, it can apply traffic shaping and increased security.
Since a metropolitan area network only refers to relative size, it may also be used to describe a public or private network that attempts to provide connectivity that covers an entire metropolitan area. In this sense, a MAN can be closely related to smart city concepts in several different ways:
As technology continues to advance and more devices become interconnected, the use of metropolitan area networks will continue to increase. Some also use MAN to refer to the high-speed internet connectivity across a city provided by 5G cellular technology, while a potential future use for a MAN would be a citywide network of autonomous vehicles sharing location, traffic and destination data.
Cisco Systems owns several buildings located in three different areas of San Jose, Calif. The company connected these sites by trenching its own fiber and leasing dark fiber from another company to form a single metropolitan area network.

It specifies an encapsulation format that allows one or more user data frames and padding octets to be carried within the confidentiality protected data of consolidating frames, hiding the users MAC addresses and original frame sizes. The transmitter can balance the privacy improvement against the loss of efficiency and delay by controlling the sizes of consolidating frames and when they are transmitted. YANG configuration and operational state models are defined both for the existing functionality of IEEE Std 802.1AE and for the functionality to be added by this project. An SNMP MIB will be defined for the added functionality. This amendment also describes privacy considerations for the use, design, and deployment of bridged networks. This project includes technical and editorial corrections to existing IEEE Std 802.1AE functionality.
