Welcome to CloudNets where networks meet cloud and today we’re going to talk about the last mile redundancy dilemma and we have our last mile expert, Brad. Thank you for joining. Brad, when you come to connect business customers, usually you worry about the last mile redundancy.
What are the considerations around the last mile redundancy dilemma?
Well, many of our customers are considering whether to pull a single connection to the customer or maybe work with dual connection. Dual connections, Dual homing. Dual connections present their own problem because they’re twice the cost. The single home connections obviously lack the redundant data plane and control plane.
What is the consideration about the node that is connected to the customer?
You need a chassis.
Typically customers with a single home run to the customer rely on dual RPs or a chassis based model to be able to survive some sort of a bad event on the network. Right. So you need a dual RPs, you need some sort of a state that you keep between those RPs like SSUs what are getting more and more complicated. And so that’s a complex configuration for network and experts of any size and scale.
Is there a way to make it simpler?
Yes, there is. And we’ve seen a massive exit from many customers that are traditionally chassis have been used a traditionally chassis based approach to more of a fixed boxed approach. They do dual runs to the customer. Right. And they rely on some sort of IGP to be able to control that. I think in the case of DriveNets and what we bring to the table is the ability to take fixed elements, fixed white box elements and build a virtual chassis providing you both, AKA DDC.
Correct.
Providing you both the benefits of dual home runs to the customer. For redundancies, there’s no single element that is a single point of failure at the same time giving you the flexibility of that massively engineered control and data plane that is completely resilient, completely redundant.
Oh, that’s great. Again, enjoying the best of both worlds with DDC. So you can address the need of more and more customers that want a dual home to two different boxes in your central office. And on the other side you don’t need to deploy multiple, you know, standalone boxes and a tricky IGP configuration in order to make this redundancy happen. You can have DDC which has the features of a chassis, but the distribution and scalability and redundancy of this multiple boxes configuration. Thank you very much Brad for joining. Thank you for watching. See you next time on CloudNets.
