industry. Networks are complicated and admins work hard to keep it running smoothly. However, network environments are also unpredictable and dynamic: any unmonitored issue could snowball into an outage.</p> <p>Optimizing network performance is necessitated by the introduction of:</p> <ul> <li>New devices and applications.</li> <li>Technologies like cloud, big data and virtualization.</li> <li>Virtual private network (VPN) connections due to work-from-home policies.</li> <li>Distributed infrastructures like data centers.</li> </ul> <p>While all of these are inevitable in a networking environment, IT admins must find a way to tackle these network pitfalls, which leads to <b>network optimization</b>.</p> <h2>How to optimize network performance for maximum efficiency?</h2> <p>You can't optimize what you can't see. A step-by-step approach to network optimization is given below.</p> <ul> <li><a href="/network-monitoring/tech-topics/network-optimization.html#critical-aspects">Identifying critical aspects that impact network performance.</a></li> <li><a href="/network-monitoring/tech-topics/network-optimization.html#monitoring-critical-aspects">Continuously monitoring these critical aspects for abnormalities.</a></li> <li><a href="/network-monitoring/tech-topics/network-optimization.html#find-root-cause">Finding the root cause of performance lag.</a></li> <li><a href="/network-monitoring/tech-topics/network-optimization.html#automating-network-optimization">Automating network optimization.</a></li> </ul> <p>Once the root cause is found, you can optimize network performance by using a <b>network optimization tool</b>.</p> <h3 id="critical-aspects">Identifying critical aspects that impact network performance</h3> <p>While there are multiple devices and parameters to be monitored in a network, only a handful of factors influence the performance of a network. Some key factors that greatly impact network performance include:</p> <ul> <li>Latency</li> <li>Jitter</li> <li>Packet loss</li> <li>Device uptime or availability</li> <li>Device health and performance <ul> <li>CPU utilization</li> <li>Disk utilization</li> <li>CPU temperature</li> </ul> </li> </ul> <h3 id="monitoring-critical-aspects">Monitoring critical aspects, and optimizing with network optimization tools</h3> <p>Monitoring key performance indicators helps in optimizing network parameters. Manually monitoring these for the hundreds and thousands of devices in a network is impossible. To monitor these critical metrics and optimize them for maximum efficiency, you need network optimization tools, like ManageEngine's powerful network optimizer tool, <a href="https://www.manageengine.com/network-monitoring/">OpManager</a>.</p> <p>Latency: Latency is the time between a request and its corresponding response. When the response time for requests increases, the latency increases, which in turn affects the end-user experience.</p> <p>Jitter: Jitter is the result of asymmetric data packet transmission. It makes audio and video calls choppy.</p> <p>Packet loss: When data packets fail to reach their intended destination, it's called packet loss. This results in dropped calls and subpar network performance.</p> <p><img src="/network-monitoring/images/Availability.JPG" style="width: 1920px;" title="Availability timeline" alt="" /></p> <p><strong>Tolerance levels</strong></p> <table class="table"> <tbody> <tr> <td>Latency: 100 to 125 milliseconds**</td> </tr> <tr> <td>Packet loss: One to two and a half percent**</td> </tr> </tbody> </table> <p>**Depends on your company's quality of service (QoS) policies and risk appetite.</p> <h3>Monitoring latency, packet loss, and jitter</h3> <p>OpManager, a complete network optimization solution generates alerts when the user set multilevel threshold values are breached for network parameters such as latency, packet loss and jitter.</p> <h3 id="find-root-cause">Identifying the root cause, and optimizing the network for performance</h3> <p>Network optimisation can be enforced with the root cause analysis feature. You can compare data from multiple monitors in a single window to track down the source of an outage and optimize network performance.</p> <p><img src="/network-monitoring/images/rca-profile.png" style="width: 1920px;" title="Graphical visualization of IT data in RCA" alt="" /></p> <p><strong>Device uptime or availability</strong></p> <p>The critical network devices in a networking environment include:</p> <ul> <li>Application servers</li> <li>Web servers</li> <li>Switches</li> <li>Routers</li> <li>Load balancers</li> <li>Wireless LAN Controllers (WLCs)</li> <li>Storage devices</li> </ul> <p>When any of these devices are not available, it can wreak havoc in daily business operations, or make your organization seem less reliable in the eyes of your customers.</p> <p><strong>Acceptable downtime</strong></p> <table class="table"> <tbody> <tr> <td>Devices: 21.56 minutes/month, or 99.95 percent availability**</td> </tr> </tbody> </table> <p>**Depends on your company's QoS policies and risk appetite.</p> <p><strong>Monitoring device availability</strong></p> <p>OpManager equips you to perform network optimization by monitoring the availability of critical devices such as servers, routers, switches, load balancers, storage devices, and WLCs from vendors like Cisco, Aruba, HPE, Huawei, or Juniper. OpManager offers over 53,000 vendor templates for monitoring network devices, and employs a wide range of protocols including Internet Control Message Protocol (ICMP), Simple Network Management Protocol (SNMP), Windows Management Instrumentation (WMI), and more to immediately alert you when any devices are unavailable.</p> <h3 id="automating-network-optimization">Automating network optimization</h3> <p>OpManager's Workflow feature automates network performance optimization services. Using the drag-and-drop workflow builder, all you have to do is set up a ping test and a DNS lookup for the critical devices in your network. If the device doesn't respond to the ping test or the DNS lookup, OpManager automatically triggers the workflow to start, stop, or reboot the device. In doing this, you can choose which network processes to automate to achieve prime network optimization.</p> <p><img src="/network-monitoring/images/Automated-workflow-for-service-restart.png" style="width: 1920px;" title="Automated workflow for service restart" alt="" /></p> <p><strong>Device health and performance:</strong> Ensuring good device health is paramount for network optimization. The health of any device can be summed up with the following factors:</p> <ul> <li>CPU utilization: CPU utilization refers to the amount of work handled by the CPU over any period. High rates of CPU utilization indicate poor performance and high wait time for tasks in the queue.</li> <li>Memory utilization: Memory utilization refers to the amount of physical memory used for processing. This value is an average over time.</li> <li>CPU temperature: High CPU temperatures negatively impact performance. This could be due to airflow issues, cooling system failure, or heavy CPU workloads.</li> </ul> <p><strong>Acceptable utilization levels</strong></p> <table class="table"> <tbody> <tr> <td>Server: 60 percent CPU utilization and 50 percent memory utilization**</td> </tr> <tr> <td>Router: 40 to 50 percent CPU utilization and 50 percent memory utilization**</td> </tr> <tr> <td>Switch: 50 to 60 percent CPU utilization and 50 percent memory utilization**</td> </tr> </tbody> </table> <p>**Depends on the workloads, device make and model, and your company's QoS policies and risk appetite.</p> <h3>Monitoring device performance</h3> <p>With OpManager, you can monitor CPU usage, memory usage, disk usage, CPU temperature, and other metrics of servers, routers, switches, and other networking devices in real time. OpManager supports protocols such as SNMP, WMI, and command-line interface (CLI), providing data with up to one-minute granularity and helping you identify devices with substandard performance and critical issues.</p> <h3>Optimizing network performance</h3> <p>Once these devices are identified, you can navigate to the device snapshot page in OpManager and view all the processes and services active in the servers. You can remotely kill these processes and services to help bring CPU and memory usage down significantly. Additionally, creating workflows to automate network processes using OpManager's Workflow feature ensures optimal performance for these tasks, and eliminates the risk of human error.</p> <p><strong>Use case: </strong></p> <p>In any organization, the primary edge device (router/firewall directly connected to ISP) greatly impacts the network performance. If the primary edge device is dropping packets and the ISP link is up, the secondary device or interface will not switch over automatically.</p> <p>It needs a manual intervention. IT admin will login and switch to the secondary device/ interface only after complaints are raised by users on network performance. This time lag and manual intervention impacts business service and continuity. Using OpManager, the IT admin can monitor the primary edge device proactively and receive alerts when the packet drop is high. The IT admin can also automate this process using workflows in OpManager. The secondary device can be automatically switched by executing Configlets (configuration templates) using workflows..</p> <p>Similarly, IT teams can take advantage of OpManager's <b>network optimization tools and techniques</b> to optimize their networking environment.</p> <p>Whether you want to monitor your network, optimize it, or even automate optimization, OpManager has got you covered. <a href="https://www.manageengine.com/network-monitoring/download.html">Download OpManager now</a>, for effortless network optimization.</p> <div class="accordion_container"> <h2 id="more-on">FAQ</h2> <div id="q1" class="accordion_head"> <h2 class="faqh">What is network optimization?</h2> <span class="plusminus">+</span></div> <div class="accordion_body" style="display: none;"> <p>Network optimization is the process of improving network efficiency with the help of sophisticated tools and dedicated network configurations, and often without introducing any additional hardware into the network.</p> </div> <div class="accordion_head"> <h2 id="q2" class="faqh">Why is network optimization important?</h2> <span class="plusminus">+</span></div> <div class="accordion_body" style="display: none;"> <p>Sub-optimal network performance leads to frequent network outages, slow connections and dropped packets.
