WAN Optimization 2.0 – tomorrow’s content delivered on Today’s WAN

The presenter – Chris Webber (BlueCoat) pointed during the presentation several important points such as:

  • Drive to consolidation;
  • Virtualization enables consolidation to data centers;
  • Business critical applications would move to web delivered protocol (http, https), video, cloud content. People working remotely.
  • WAN opt must evolve: enable critical applications, new network architectures
  • If in the past it was hard to maintain control over data in local access, the storage and files were centralized, now the process is transferred to a data center, which would increase the bandwidth and the new performance issues would arise due to the distance, although the main information would e centralized in one place, instead of different branches of the enterprise.

He predicts that in the future the public clouds would play a major role and the cotrol would be over the far end.

Webber states also that we are going from File servers to collaboration servers and all these changes impose the need to understand protocols in order to optimize them (save time).

One of his major points is that because 30 to 60% of the enterprise traffic is recreational, we can reduce bandwidth by byte caching and adaptive compression, object caching (this keeps the whole thing locally), another option is HTTP/S pipelining.

Enterprise Apps also require accelerated web – reduce bandwidth and remove latency in rich media in enterprise apps with: live video stream splitting (http, ssl, rtsp, rtmp,mms), video object caching (http, ssl, rtsp, mms), content distribution (pre-populate content to every branch).
