Sebagai suatu jaringan bertumbuh dalam ukuran dan kompleksitas, menjadi semakin penting bahwa itu direncanakan dengan baik, logis terorganisir dan didokumentasikan dengan baik.

Banyak organisasi mengembangkan konvensi untuk penamaan dan pengalamatan komputer. Ini memberikan pedoman dan aturan yang dapat digunakan oleh personel dukungan jaringan saat melakukan tugas ini. Nama Komputer harus unik dan harus memiliki format yang konsisten yang menyampaikan informasi yang berarti. Hal ini dapat membantu untuk menentukan jenis perangkat, fungsi, lokasi dan nomor urutan berdasarkan nama perangkat. alamat IP juga harus unik untuk setiap perangkat.

Penggunaan perangkat logis penamaan dan pengalamatan konvensi yang terdokumentasi dengan baik dapat sangat menyederhanakan tugas pelatihan, manajemen jaringan dan dapat membantu dengan pemecahan masalah ketika masalah timbul.

Metropolitan Area Networks (MANs) are high speed private networks which are created by one or more dedicated point to point links between multiple locations. Each location normally has its own LAN and some level of routing will have to be done between the MAN and disparate LANs so that the two networks can communicate and share information. MANs can be created via the use of a public switched network, private fiber network or one or more point to point wireless links. As an example lets take a large University with a campus spanning several square miles and multiple buildings that wants a centrally managed IP Video Surveillance network. Well a MAN would be set in place to connect each of the buildings across the campus to a central location where the NVR and storage array are installed. The high speed of the MAN will allow the IP video to be quickly transported to the central location and recorded as if the remote cameras were on the same LAN as the NVR. If that does not make sense here is a diagram...

Multi-building ip video surveillance network connected via a MAN

As you can probably guess the Wide Area Network (WAN) connects two or more LANs that can be located large distances from one another, even across the globe. A WAN can be your Internet connection or it can be a "private" point to point (no internet) frame relay, managed layer 2 or MPLS connection you get from your internet service provider (ISP). Traditionally WANs are public switched circuits like DSL, Cable, T1s, T3s and OC3 to OC192.

Circuit Speeds:

* T1: 1.5Mbps
* T3/DS3: 45Mbps
* OC3 (Optical Carrier 3): 155Mbps
* OC12: 622Mbps
* OC48: 2.488Gbps
* OC192: 9.6Gbps

These are still the most prevalent WAN connections but the problem is they become very expensive very fast and when dealing with video surveillance we all know that bandwidth is our major concern. Well, today ISPs are combining MANs and WANs to create Metro Ethernet offerings that provide you with a high speed Ethernet handoff that plugs directly into your firewall or layer 3 switch instead of a router which means a much lower monthly costs and MUCH lower hardware costs.

Metropolitan Area Networking (MAN)
Is a network that connects computers in a building that brdekatan / still in the city or province.
Benefits:
. The network is also often called an intranet.
. The software and hardw · are used very specific.

Definition: A WAN spans a large geographic area, such as a state, province or country. WANs often connect multiple smaller networks, such as local area networks (LANs) or metro area networks (MANs).
The world's most popular WAN is the Internet. Some segments of the Internet, like VPN-based extranets, are also WANs in themselves. Finally, many WANs are corporate or research networks that utilize leased lines.
WANs generally utilize different and much more expensive networking equipment than do LANs. Key technologies often found in WANs include SONET, Frame Relay, and ATM.

Is a network that covers a very wide area, country / continent.
Benefits:
· Network uses satellite subsea.
· speed data transfer is 64 kbps.
. In this network there is one central computer called a host.

Definition detail : A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications. A LAN in turn often connects to other LANs, and to the Internet or other WAN. 


Most local area networks are built with relatively inexpensive hardware such as Ethernet cables, network adapters, and hubs. Wireless LAN and other more advanced LAN hardware options also exist.

Specialized operating system software may be used to configure a local area network. For example, most flavors of Microsoft Windows provide a software package called Internet Connection Sharing (ICS) that supports controlled access to LAN resources.
The term LAN party refers to a multiplayer gaming event where participants bring their own computers and build a temporary LAN.


Also Known As: local area network
Examples:
The most common type of local area network is an Ethernet LAN. The smallest home LAN can have exactly two computers; a large LAN can accommodate many thousands of computers. Many LANs are divided into logical groups called subnets. An Internet Protocol (IP) "Class A" LAN can in theory accommodate more than 16 million devices organized into subnets.

Benefits include:

· Used to connect multiple computers located within the building / office.
· LAN network called the local network.
· file servers to provide software services to manage the network and store data.
· topology used for the LAN network is a ring topology and bus topology.
