Optimizing WAN Bandwidth

Wide Area Networks (WAN) offer reliable connectivity. In such cases WAN optimization provides the solution, because it improves bandwidth and facilitates smooth network traffic without purchase of additional bandwidth. It also helps with application performance management.

Adaptive Private Networking (APN) technology increases bandwidth by 10 to 20 times. APN is useful in measuring performance to route traffic efficiently. This performance measurement allows the network to detect transmission problems and immediately reroute traffic around the trouble spot using a different pathway. This technique is useful for the companies which has operations internationally. The important benefit of an APN is versatility because it can be used with virtually any network configuration. An APN grants companies the flexibility to keep their existing private Wide Area Network, and adds bandwidth.

WAN bandwidth optimization tools and techniques:
  • Protocol substitution or protocol proxy
  • Hardware Compression
  • Compression or Symbol Dictionaries
  • Object Caching
  • Traffic shaping and management
  • Traffic prioritization and grooming
  • Forward error correction

The following are the reasons for raising the bandwidth:
  • Web enabled applications
  • Broader proliferation of applications
  • Global integration
  • Richer content
  • Increased interaction with voice and video

The major cost for a company in IT budget is the cost for network, either it may be internet access or a private WAN. The cost of bandwidth depends on the type of network, the speed, and time and also the service provider and country in which the business is operating.

By increasing the bandwidth the company’s efficiency can be increased dramatically and application performance also increases.
