More than 30 percent of enterprises have facilities with DS3 (45 Mbps) or greater WAN
connection, including mid-sized data centers and regional hubs.
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
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.
The ConnectPort WAN
delivers this speed for a wide range of commercial applications.
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.
The most well-known example of a WAN
is the Internet.
