Cisco Pushes AI, Machine Learning Out Across the Network

CISCO LIVE 2019 — Cisco Systems continues to infuse artificial intelligence and machine learning throughout its networking architecture and stretch more of its capabilities out to the internet of things and the edge. It’s part of a larger plan to create a single network architecture that will support that multiple domains that make up a modern enterprise.

In an increasingly cloud- and data-centric world, applications and data are now accessible from myriad places – from the data center and cloud to the devices that making up the fast-growing IoT – and networks need to be able to support not only workloads in the data center, branch and campus areas but also the cloud, the edge and service provider environments, according to Scott Harrell, senior vice president and general manager of Cisco’s enterprise networking business.

At the same time, employees and other users are becoming much more mobile and want to be able to access any application at any time and from any device and on any network.

Managing and securing such a complex environment is a complex challenge and AI and machine learning can ease some of the headaches, Harrell said during a press conference Monday at Cisco Live 2019 in San Diego. The technologies also can help enterprises pull greater insights and information from the vast amounts of data they’re gathering than humans can.

“Now, with things like big data and AI, machines can come along and free us from our mental limitations and allow us to do more creative things and more incredible things than we ever could before,” Harrell said.

Cisco is introducing AI Network Analytics, which will be a standard part of the company’s DNA Assurance offering, with the next release of its DNA Center network management automation offering this summer.

Harrell pointed out that machine learning will help in the area of detecting security and other problems within the network. Traditional companies have created baselines of normal behavior within the network and then have the management system send out alerts when behavior strays outside of those baselines. The problem is that not all baselines apply to all companies, and enterprises can find themselves responding to large numbers of alerts, many of which aren’t an issue.

“What we do with machine learning is rather than using static baselines, we learn what is normal for your environment and we say that we’re only going to trigger an alert when we see something that’s abnormal for your environment,” Harrell said.

Working with 11 customers over a three-month period, Cisco said that using DNA Center and DNA Assurance, the customers would have found about 8,000. With machine learning, only 303 alerts were sent out based on their situations, about a 75% drop over the number that normally would have been issued.

“It’s a huge, huge increase in IT efficiency,” Harrell said.

Cisco also is integrating its SD-Access with SD-WAN and Application Centric Infrastructure (ACI) offerings to simplify the process of bringing users and devices onto the network, authorize them and segment them across branch, campus, data center and cloud networks. The segmentation is important to securing data and applications by denying unauthorized access to the network.

It’s also another step in Cisco’s plant to create a single networking architecture that can stretch across the multiple domains. The company has bulked up what it can do within …
