PAGE 3 NetBrain: Automating Problem Diagnosis Transforming NetOps Through Intent-Based Automation As enterprises scale their hybrid networks through the adoption of new technologies, organic growth, and mergers & acquisitions , keeping the business running while minimizing operational overhead is more critical than ever. These hybrid networks must support remote work, cloud- based services, and a litany of software-defined networking technologies, each of which dramatically increases the complexity. The result? More operational service tickets. And these service tickets may number into the hundreds or thousands per week – many of them solving the same issues that have already been resolved countless times before. Continuously troubleshooting the common issues is tedious, repetitious, and inefficient. Adding more service desk personnel is a common and tactical solution to this growing problem, but it fails to achieve the desired results of lower operational costs, shorter task duration, and more consistent ticket resolutions. And the varying skill levels of operators and engineers negatively impacts the ability to effectively and rapidly solve problems. The most successful IT leaders realize that their operational plan must not only scale, but be smarter. With more than 80% of all service tickets categorized into less than a dozen types of similar issues, collectively solving this small set of common problems at scale can be transformational to the business. That’s where network automation comes in. There have been two major challenges to implementing an automation-centric approach to scalable network operations. 1. The limited visibility of the entire network, with all of the performance and configuration detail needed for every network component and their context. 2. The lack of a suitable no-code automation console that can address the simplest and most complex operational issues without the need for rigid development projects or programmers and associated costs of software engineering. of network problems are repetitive , but diagnosed the same manual way each time they occur of network problems are preventable , but organization lacks methods to enforce rules and practices 50 % 95 %

PAGE 4 NetBrain: Automating Problem Diagnosis Understanding Your Network Automation Maturity While IT professionals generally accept that automation can be a highly transformational technology, it may be surprising to realize that the vast majority of organizations have remained at “Level 0” (No Automation) since their IT operations function was created! These organizations ‘grew up’ on much simpler networks which they managed manually and, even as the world around them changed, the ways in which they approach network operations has not Even with the drastic increase in operational service tickets that comes with infrastructure growth, both in scale and complexity, these modernization projects have not yet become a priority But adoption is starting to increase In the 2021 Gartner I&O Leaders Survey, a majority of respondents selected automation implementation as a key driver for I&O cost-efficiency, with 23% ranking it as the top driver to cost optimization in their organizations.

PAGE 5 NetBrain: Automating Problem Diagnosis Consider network automation as a journey that can be broken down into highly achievable steps over time. Referring to the chart, you can see that as your maturity progresses from one level to the next, you derive greater value and operational scale Mean-Time-To-Repair (MTTR) can be used as a proxy for maturity as it forms the baseline case for a completely manual operational plan In the chart, we see that as the use of automation increases, MTTR decreases The net difference between the two curves is the true and very tangible value of migrating to an automation-centric network operations approach You can see from the chart why MTTR is used as a proxy to understand the value of automation Most organizations can articulate their average MTTR These organizations have manual processes, so their MTTR can be used as the baseline in their automation journey As organizations become more mature in their automation, it is quite easy to determine the tangible savings being realized through automation In simpler terms, the four hours that you typically spend manually executing a service ticket with CLI, may be reduced to two hours through automation, a savings of 50% And with large organizations reporting 5,000 or more service tickets per month, this yields a monthly aggregate savings of about 10,000 hours (or approximately 60 operators), which at prevailing engineer hourly rates can be estimated at almost $1 million per month! LEVEL 0 MANUAL Manual troubleshooting via Command Line Interface (CLI) Must understand every detail of every device LEVEL 1 INTERACTIVE Engineer uses automation to increase data collection and analysis efficiency Leveraging Runbooks and Dynamic Maps LEVEL 2 COLLABORATIVE Engineers are writing automations for teammates to use and share their knowledge in executable format Leveraging Guidebooks LEVEL 3 TRIGGERED Event or incident triggered execution of diagnosis for all known problems begins instantly Output results to NetBrain incident portal LEVEL 4 PREVENTATIVE Proactive validation of network intents running continuously in the background Enforce design rules, security policies and application best practices BASELINE MTTR MEAN TIME TO REPAIR AUTOMATION MATURITY NetBrain PDAs Advantage • Scale Network Operations • Reduce MTTR, Leverage SMEs • Prevent Problems From Happening Again • Reduce Human Dependency & Errors

PAGE 6 NetBrain: Automating Problem Diagnosis Level 0 is considered the traditional approach to network operations It is largely based on traditional CLI- based manual operational tasks and is tightly coupled to and reliant on the operator or engineer’s skills and experience There are no economies of scale, execution is inconsistent from ticket to ticket, and each task requires subject matter expertise which may be quite limited in availability The first step “Level 1” or “Interactive” is when intelligent tools are used to make more informed decisions These tools provide more information in one place, the context of all aspects of connectivity, enabling network engineers to be more productive Level 1 offers guardrails for any operator or engineer to help them make more informed decisions based on the real-time status of the network In “Level 2” automation, the “Collaborative” stage, is where engineers and operators leverage the knowledge of their peers Software captures subject matter experts’ knowledge to create automation units available to any user regardless of their own knowledge or experience In this stage, their expertise is available even when the expert is not “Level 3” is where automation responds to external events, such as those from ITSM solutions This is where significant automation appears as the software begins automatically taking actions required by service tickets before engineers or operators get involved Level 3 shifts the operational paradigm from human-centric to automation-centric, and in the process, further reduces MTTR and provides significant savings at scale Lastly, “Level 4” introduces the concept of enforcement of in-production conditions running tasks continuously in the background Engineers create these tasks based on the enterprise architects’ goals such as assuring the network infrastructure delivers bandwidth as needed or that ACLs or other protocol filters are in place for security reasons As you introduce new applications, it is common to change network conditions in support of the new application, but to the detriment of one or more of the existing applications Preventive automation assures that each of the application requirements are respected and continuously validated

PAGE 8 NetBrain: Automating Problem Diagnosis Automating Problem Diagnosis The network operations paradigm must change As modern infrastructures grow in scope and complexity, they generate hundreds or thousands of service tickets per month, which seems overwhelming, but consider that the vast majority of these service tickets share common issues It turns out that network operational teams spend most of their time repeating the same diagnostic and remediation tasks, which is highly inefficient The entire operation function must get smarter in order to enable existing teams to automate these repetitive problems and reduce their overhead NetBrain PDAs makes network automation intelligent by understanding and managing the intents of the network PDAs enables you to solve any problem once by capturing the diagnostics and remediation workflows without any programming, and then re-using that knowledge for each subsequent occurrence of the same or similar problem NetBrain PDAs scales network operations using automation to: • Reduce the number of required operational resources by handing most tedious and repetitive problem diagnostics automatically at the moment a service ticket is created • Transform subject matter expertise into reusable executable automation units for use by anyone on-demand or to run automatically • Equip operators and engineers with a highly intelligent, network-aware visual management platform enabling them to solve complex problems in a more consistent and repeatable fashion

PAGE 9 NetBrain: Automating Problem Diagnosis Problem diagnosis begins the moment a ticket is created NetBrain PDAs begins working the moment an external event occurs Any service ticket can trigger NetBrain PDAs to begin mapping and diagnosing the network vicinity involved NetBrain then programmatically executes any set of best practice tasks, records the results and then sends the detail back to the ITSM provider By adding this critical diagnostic detail to every service ticket, operators and engineers become more productive when they start working, reducing the upfront time spent on repetitive diagnostics and investigatory tasks Transforming knowledge into automation NetBrain PDAs enables the knowledge and experience of subject matter experts to be converted to executable automation without the need for software engineers or code development projects By reusing previously created automation, operators and engineers can gather, analyze and resolve problems that before would have required the attention of other subject matter experts or specialized operational staff Now, everyone can get online at the same time, interact and make updates and remediations to reduce or eliminate hand-offs and escalations to DevOps, SecOps, NetOps, CloudOps, automation teams Automation to enforce the intents of your network design Intent-based automation (IBA) ensures your network continues to provide the required levels of service your applications require Network intents can enforce network design constraints, quality of service, bandwidth expectations, security policies, and application path preferences These rules (or intents) can range from the purely technical (e g , assuring packet size) to domain specific (e g , access policy) to business-driven (e g , throughput levels for a customer-facing network application) IBA allows network operations teams to increase the autonomy of their networks and reduce service ticket volume

PAGE 10 NetBrain: Automating Problem Diagnosis With NetBrain PDAs you can create any number of network design enforcement intents Most commonly these enforcements are set to run in the background without any operator intervention for intelligent and preventative network monitoring, compliance, and policy and best practice enforcement of the entire network This prevents new business application services from stepping on deployed business services NetBrain’s intents detect and address abnormal network behaviors prior to them becoming a bigger problem Alleviate the stress of change management NetBrain PDAs empowers you to make highly informed changes interactively, execute commands automatically, and then proactively verify the impact of these changes to the rest of your business applications It gives network engineers a single place to keep track of changes in a way that is fully auditable and adherent to existing business protocol and approval processes NetBrain PDAs provides the ability to take benchmarks before and after each change to ensure that the designer’s intentions are preserved And in cases of conflict, you can easily execute rollbacks
