Thanks to all who joined us for the Comcast Business 2017 SD-WAN and Virtual Edge Report webinar, Developing a Hybrid Plan for SD-WAN, where they discussed how to ease into SD-WAN to test and experience new business capabilities across a distributed enterprise. After the webinar we took questions from the audience. Unfortunately we ran out of time before we could get to all the questions. Read the full Q&A below.
If an enterprise chooses to use AWS, Azure, etc… for workloads, can the enterprise own their own SD-WAN Controller? How does it interwork with AWS/Azure Controller and SFC?
Comcast: No, if an enterprise chooses to use PaaS platforms like AWS/Azure for workloads we will still use a centralized controller. Integration into AWS/Azure for orchestration is in our roadmap.
How does NFVI topology be visualized both for enterprise and AWS/Azure?
Comcast Business: We will treat NFVI topology the same way as we treat a physical site for visualization purposes.
How can SD-WAN integrate mobile devices connected via cellular networks?
Comcast Business: SD-WAN can use fixed mobile devices such as LTE modems routers to provide an underlay service. For BYOD and Mobile VPN you still need the right VNF to handle those devices accessing network resources.
So, MPLS will become deprecated with the advent of SD-WAN?
Comcast Business: We foresee MPLS remaining for a few years as customers figure out what applications are still bound to it, like every technology before (ATM/FR/X.25) MPLS will lifecycle into something else. Our view is that SD-WAN is what enterprises will lifecycle to.
Comcast Business: SD-WAN can give you the benefits of bandwidth aggregation, application aware routing and traffic steering over any type of underlay. For multi-gig aggregation, gig point to point, etc. the benefits come from application aware routing, managed VPN, centralized configuration and virtualized network function deployment.
