The WAN is the New LAN

The WAN is the New LAN

This post is an excerpt from a Gartner research report. 

Organizations are struggling to cope with the increasing demand for enterprise WAN bandwidth. It is growing 30% per year, driven by video, cloud, real-time collaboration applications and the growth of the digital enterprise.

Along with cloud computing, video and application encryption are driving enterprises to update their WAN architecture. While there has always been a demand for more WAN bandwidth, the demand requirements for WANs will obligate enterprise networking and sourcing managers to upgrade their WAN on a more frequent basis.

Enterprises often lack a single, logical WAN architecture that integrates their existing Internet, Multiprotocol Label Switching (MPLS) and virtual private LAN service (VPLS) WANs.

Recommendation

Investigate using software-defined networking (SDN) technology to integrate hybrid WAN architectures into a single logical WAN service. The future WAN will manage applications based on the session, which will enable the same application to be managed differently depending on the user, device and/or time of day.

Migrating to a LAN strategy in the WAN will benefit those enterprises that have high current and/or future bandwidth and agility requirements.
