WAN

(Wide Area Network) A long-distance communications network that covers a wide geographic area, such as a state or country. The telephone companies and cellular carriers deploy WANs to service large regional areas or the entire nation. Large enterprises have their own private WANs to link remote offices, or they use the Internet for connectivity. Of course, the Internet is the world's largest WAN.

WANs, LANs and MANs
A LAN (local area network) is contained within a building or complex. A MAN (metropolitan area network) generally covers a city or suburb. Following is a bandwidth comparison between major LAN and WAN technologies. See LAN, MAN and personal area network.

After set-up and traffic streams were running, testers determined whether the optimized traffic stream over the WAN could be monitored and if NetFlow messages could be received from the Cisco router to properly display the active traffic flow statistics from the WAN link.
In addition to standard cellular modem communications, the Digi Connect WAN IA also offers local intelligence with features such as network routing, persistent connections, firewall and a secure integrated remote management software package.
ARC WAN Optimization integrates advanced technologies that reduce WAN latency and bandwidth consumption to accelerate all TCP-based applications, including Web (HTTP) applications, Microsoft SharePoint, FTP and replication and backup applications.
As IT departments centralize servers to achieve regulatory compliance and lower costs, WAN optimization controllers (WOCs) must deliver LAN like application performance to remote clients.
The Orbital 6000 series includes the Orbital 6800 for datacenter deployment and the Orbital 6500 designed for branch offices -- the two products can be used in configurations supporting up to 300 branch offices and WAN links up to 500 megabits per second.
Although the latency penalty for each individual message and response can be small for WAN circuits (20-30ms for local Campus, 120ms for NYC to UK access), the number of messages and responses made during the reading or writing, of even a small file, add up to make the total delay quite large.
Inside the Market for WAN Management Outsourcing details the results of a major survey of network managers and IT executives across the country.
The very large, high capacity WAN links that are used to transfer bulk data are, however, often painfully underutilized due to latency and TCP protocol constraints that severely impact throughput and data transfer speeds.
Due to limited availability, bandwidth costs have been the most significant cost in WAN structures, but communications costs are expected to follow the route of Moore's Law and significantly decrease in cost as infrastructure is made more readily available.
