Pourquoi un WAN? Les organisations ont besoin de partager les informations avec d'autres organisations. Ils fonctionnent sur la couche 2. On distingue deux types d'interfaces RNIS : 8. Ceci comprend aussi une partie pour la synchronisation. Il est possible de n'utiliser qu'une seule interface de routeur pour connecter plusieurs sites par des circuits virtuels permanents.

La cellule ATM de 53 octets est moins efficace que les trames et paquets de plus grande taille de Frame Relay. MPLS est une technologie du fournisseur de services. Cependant, MPLS peut transmettre tout type de paquets entre sites. Les avantages d'un VPN sont les suivants : SalmaDarhouane Dec.

You just clipped your first slide! A wide area network may be privately owned or rented from a service provider, but the term usually connotes the inclusion of public shared user networks. Both packet switching and circuit switching technologies are used in the WAN.

Packet switching allows users to share common carrier resources so that the carrier can make more efficient use of its infrastructure. In a packet switching setup, networks have connections into the carrier's network, and many customers share the carrier's network.

The carrier can then create virtual circuits between customers' sites by which packets of data are delivered from one to the other through the network. Circuit Switching allows data connections to be established when needed and then terminated when communication is complete. This works like a normal telephone line that works for voice communication. When a router has data for a remote site, the switched circuit is initiated with the circuit number of the remote network.

Some network mapping symbols for network engineer. You can find more symbols for WAN diagrams here. Edraw is a powerful diagramming tool helping network engineers and network designers draw wan diagrams easily and quickly.

A metropolitan space network MAN could be a network that interconnects users with pc resources in an exceedingly geographic space or region larger than that lined by even an oversized local area network LAN however smaller than the realm lined by a wide area network WAN.

The term is applied to the interconnection of networks in an exceedingly town into one larger network which might then conjointly provide economical affiliation to a large space network. The latter usage is additionally generally mentioned as a field network. Examples of metropolitan area networks of varied sizes are found within the metropolitan areas of London, England; Lodz, Poland; and Geneva, Switzerland. A recent trend is that the installation of wireless MANs. A wide area network WAN may be a telecommunications network or network that extends over an outsized geographical distance.

Wide area networks are typically established with hired telecommunication circuits. Business, education and government entities use wide area networks to relay information to employees, students, clients, buyers, and suppliers from numerous locations across the planet. In essence, this mode of telecommunication permits a business to effectively perform its daily performs no matter its location. Related terms for alternative kinds of networks are personal area networks PANs , local area networks LANs , campus area networks CANs , or metropolitan area networks MANs that are sometimes restricted to an area, building, field or specific metropolitan area respectively.
