Network Engineering & Performance Optimization

Network Engineering

Wide area networks generally consist of extremely slow links (compared to LAN speeds) and connections that interconnect branch offices, vendors, as well as partners. Even with bandwidth costs dropping, these links and connections are extremely expensive.

WAN Optimization is a solution that uses a symmetric approach to application optimization, that is, a device on each side of the WAN or a software application integrated with client devices and servers that has application-specific intelligence and network-specific intelligence. The optimizers are available as a router-integrated network module or as standalone appliances, it could deploy out of the data-path in the data center and in the remote office LAN.

Optimization helps to enable infrastructure consolidation while improving WAN utilization efficiency and application delivery through the following application acceleration and WAN optimization features:

  • Transport Flow Optimizations (TFO) – TFO provides standards-based, field-proven through put improvements for TCP-based applications while maintaining packet-network friendliness and safe coexistence with other network nodes communicating using standard TCP implementations.
  • Caching – Caching is a bidirectional database of traffic that has been previously-seen traversing the network. Caching inspects incoming TCP traffic and identifies patterns within the message. Once patterns have been identified, small signatures, thus minimizing the bandwidth consumption of each message significantly, can safely replace redundant patterns. Caching can provide anywhere from 2:1 to 200:1 compression based on the application used and data being transmitted.
  • Compression – Compression is a standards-based compression that can be employed to further minimize the amount of bandwidth consumed by a TCP flow. Compression can be used in conjunction with Caching or independently. Compression can provide anywhere from 2:1 to 4:1 compression based on the application being used and data being transmitted.

NEXT can help organizations audit networks to identify network bottlenecks and help in systematically removing those bottlenecks. We also specialize in WAN optimization solutions to increase the performance and efficiency of organizations and their branches there by increasing productivity multi-fold in low-bandwidth WAN architectures.
