Campus Area Network (CAN)
This solution is larger than LANs, it can be spread across several buildings that are fairly close to each other to enable users share information and resources.
Metropolitan Area Network (MAN)
This solution is also larger than LANs which can be use to incorporate elements from both types of networks. it goes across entire geographic areas (town or city or sometimes campus).
Wide Area Network (WAN)
This solution connects organization with branch offices outside city, state, country. it is a service that connects computers together remotely, across longer physical distances to communicate over one large network. It helps to connect to other networks across the globe that will enable shared resources, video/voice call and downloads over the internet.
Passive Optical Local Area Network (POLAN)
This solution is an alternative to typical switch-based Ethernet LANs. The technology can be integrated into structured cabling to overcome concerns about supporting traditional Ethernet protocols and network applications such as PoE (Power over Ethernet). A point-to-multipoint LAN architecture, it uses optical splitters to split an optical signal from one strand of single mode optical fiber into multiple signs to serve user and devices.
Enterprise Private Network (EPN)
This solution secures organizations network that are connected to other of its business branch offices and business partners that want to securely connects its various locations for information and resources sharing.
Virtual Private Network (VPN)
This solution connect individual, small, medium and large organization via the internet, allowing its users send and receive data as if their devices were connected to the private network. Also using virtual point-to-point connection to access a private network remotely.
