What should be the level of security integration into SD-WAN products and services? That will be my question for the panel I moderate on the SD-WAN track at the MPLS+SDN+NFV World Congress. Here are some vendor views on this topic.
A review of enterprise survey about SD-WAN deployment considerations and enterprise network security as a challenge for enterprise WAN. MPLS cost being one of the SD-WAN deployment drivers raises the question, is MPLS really so expensive compared to business broadband?
MPLS is still pretty commonly used by enterprises, some use it for specific applications while others take it to the extreme and route all traffic of their branches to s central location. Service providers hit a jackpot with MPLS but this is now changing. 2 major forces are making MPLS less lucrative and eventually will kill it: MPLS price is going down; Enterprise requirements have changed
SD-WAN strengthens the position of OTT hosted UC providers vs. the incumbent operators as it makes the operators’ advantage of owning the network less valuable. SD-WAN reduced the operational cost associated with providing hosted UC in high quality as it removes the need for MPLS. Combined with WebRTC, adding real-time communications as a feature to existing SaaS applications has never been easier.
MPLS and DIA are built for the past and don’t support cost and technical requirements of the modern enterprise. SD-WAN will be like the Firewall is today for enterprises. It will become common among enterprises. It doesn’t mean MPLS will go away, but with the capability of Hybrid WAN as part of SD-WAN, MPLS will become less critical, less traffic will go over it,
If you are reading this blog I’m pretty sure you have already experienced some WebRTC calls.
And how was the quality of the audio? And the video? Typically the answer to this questions is somewhere between pretty good to great. Things get more complex when call needs to exist the WebRTC protected island. Time to discover why.
