This week, excessive efficiency community vendor, Arista Networks, held a digital “Cloud Innovators” occasion. The corporate has used occasions like this earlier than to make some main product bulletins and this occasion was no totally different, as the corporate introduced its community information lake, or NetDL in product phrases.
NetDL is the subsequent step within the evolution of the Arista platform and addresses the rise in synthetic intelligence-driven networking.

Arista was a pioneer in software program pushed networking
Arista got here to market as one of many first distributors to maneuver to a centralized software program mannequin the place its working system, EOS, was decoupled from the underlying {hardware}. Arista merchandise had been constructed with a centralized in-memory state database making networks far more dependable and programmable.
The second part of Arista evolution got here in 2016 when it launched its community database, NetDB, which was a consolidation of all information from Arista merchandise. This contains alerts, flows, packet info, management aircraft visitors and system state streaming.
NetDB created a single platform for utility and ecosystem growth. Since its inception, Arista’s differentiator has been a single picture throughout all its merchandise, which made the creation of NetDB attainable.
Nearly all different distributors have a separate working system for the WAN, WiFi, campus and different locations within the community. Making a community vast database would require ingesting the assorted sources of knowledge and normalizing it, which might require an amazing quantity of heavy lifting
NetDL powers the subsequent wave of Arista innovation
NetDL takes NetDB and provides a lot of different information sources, together with Web and programs info and information from third events resembling Zoom, Zscaler, VMware, Microsoft and Palo Alto Networks.
This provides Arista a wider set of knowledge to course of, analyze and derive operational insights from. NetDL might be considered a “single supply of fact” for community information that allow higher forensics and analytics for risk looking, community packet brokers, community detection and response, efficiency monitoring and utility expertise monitoring.
All this information has existed for years however there was a lacking hyperlink that made deciphering the info attainable at this time, the place it wasn’t up to now and that’s the rise of synthetic intelligence. NetDL is a large quantity of knowledge an AI requires information to be efficient. In information sciences, there’s an axiom that states “good information results in good insights” and that’s definitely true however it’s additionally a undeniable fact that partial information results in incomplete insights.
Using AI with NetDB would possibly set off some attention-grabbing details about the community however can be blind to the impression of the findings on cybersecurity, utility efficiency and others.
AI plus NetDL permits quicker risk looking and app efficiency monitoring
With siloed networking and safety, risk actors are capable of breach a community and transfer laterally slowly, which retains them hidden in plain sight as there may be an excessive amount of information to research manually. Even when the breach is detected, discovering the supply might be tough, if not not possible as tracing the breach to a different a part of the community requires correlation throughout a lot of programs and by the point its discovered, information has doubtless been exfiltrated.
NetDL sees all the things throughout the community and safety programs and permits the correlation of even the smallest anomalies, which can be utilized to seek out the supply of the breach and automate the reprogramming of the community to attenuate the harm.
Equally, a Zoom name that falls underneath the brink of acceptable high quality may set off an inspection of the community to troubleshoot the issue and isolate the issue. In a current AIOps research carried out by ZK Analysis, we discovered that some engineers spend half of their time troubleshooting the community.
That’s as a result of community troubleshooting might be very tough, notably on this period of software program outlined all the things, cloud and mobility as an issue in a single system can have a ripple impact and trigger issues elsewhere. AI utilized to NetDL can shortly see there’s an utility drawback after which shortly establish the place within the path of visitors the issue emanated from.
Autonomous networks is on the close to time period horizon
One other good thing about NetDL is that it enriches Arista’s autonomous digital assistant, AVA. The mixture of AVA + NetDL can shift community operations from a reactive mannequin to 1 that’s proactive because the digital agent can watch your entire community 24x7x365 and use AI / ML fashions to foretell when an issue will happen. AVA can then information community operators by fixing the issue earlier than its enterprise impacting.
The companions introduced this week needs to be considered a place to begin for NetDL. In the course of the occasion, Arista hinted at others coming in 2022 and can together with a spread of corporations together with different strategic companions and ISVs to ship market and buyer particular or utility particular insights.
The IT trade has existed in silos for many years, however that mannequin not works as functions are actually cloud delivered and customers are on the transfer. NetDL brings collectively a “full stack” of knowledge to let the community perceive not solely what occurred however why it occurred.
