As noted last time, just as the Next-generation Enterprise WAN (NEW) architecture is enabling IT to take advantage of "the cloud" - SaaS, public and hybrid cloud computing - so the cloud is enabling the next generation enterprise WAN. The ecosystem o...
Technologies of the next-generation enterprise WAN architecture deliver both of these at higher bandwidth and lower cost than MPLS.
While MTBF and MTTR for broadband are much higher than MPLS, having multiple diverse links addresses the key issue of higher uptime; MPLS's "better" SLA doesn't actually deliver what enterprises care about.
Broadband has more total bandwidth and reflects how traffic flows today, while WAN Virtualization can address the "single DSL upstream bandwidth" issue.
While enterprises need any-any connectivity, neither traffic patterns nor VoIP require a fully meshed WAN.
What was very true just a few years ago – enterprises needing MPLS to have a reliable, high-performance WAN – is no longer, thanks to the NEW architecture.
Benefits include lower costs, scalability and improved performance for both intranet and public cloud-based services/SaaS access, while maintaining centralized network security management.
Next-generation Enterprise WAN architecture addresses "trombone" effect leveraging link aggregation and colo facilities to deliver best-of-both-worlds solution.
