This document discusses the challenges facing modern networks due to increasing traffic volumes, speeds, and complexity. It identifies four key challenges: 1) managing virtualized and hybrid cloud environments, 2) handling higher network speeds like 100Gbps, 3) preventing security issues, and 4) ensuring accurate performance monitoring. It argues that network packet brokers are needed to provide visibility across networks while maintaining speed and filtering redundant data for monitoring tools. The document recommends using advanced packet brokers like cPacket Networks that can scale from 1Gbps to 100Gbps, provide zero packet loss, and optimize network performance monitoring.
Importance of Network Performance Monitoring
- 1. The challenges of monitoring networks pervasively at high speed: why packet brokers need real-time visibility
- 2. Top challenges facing today’s networks 3 4 1 2 Growth of virtual infrastructures, hybrid cloud environments and new applications Increase in traffic, data and adoption of higher network speeds (100Gbps) Preventing security issues in the network Need for accurate network performance monitoring metrics
- 3. Top challenges facing today’s networks Growth of virtual infrastructures, hybrid cloud environments and new applications • Workloads must be continuously monitored during development and production • Typical cloud monitoring tools lack holistic capabilities that network operators need to manage performance and service levels • Many organizations work in hybrid environments and use multiple monitoring tools, reducing flexibility and increasing costs Increase in traffic, data and adoption of higher network speeds • Rapidly growing traffic volumes present visibility challenges for traditional monitoring tools • Network-based monitoring technologies that were developed for more static, lower-speed infrastructures may not be able to successfully be deployed in today’s dynamic data centers • Sheer volume and speed of packets traversing the networks overwhelm most of today’s network monitoring tools because they were designed to handle lower speeds (1G or 10G) Hybrid Private Public

Crehan Research states that 25G and 100G are expected to increase rapidly and comprise over half of all shipments by 2021 Some factors driving the adoption of 25G and 100G speeds are: • Low price premium over comparable 10G and 40G switches resulting in higher bandwidth discounts • Higher bandwidth per lane: 25G uses the same number of lanes as 10G and 100G uses the same number of lanes as 40G • Strong interest and higher demand which drives significant early volumes and reduces costs even further The rise of 100G network speeds
- 5. Top challenges facing today’s networks Preventing security issues in the network • Existing security tools are not capable of processing higher volumes of data • At 100G networks, speed becomes an issue because many security tools struggle to provide an accurate analysis of all the network traffic • Companies often make trade-offs between security, cost and performance: a. some will slow down their networks to allow their security tools to keep up b. they will turn off essential security tools such as firewalls and/or SSL decryption c. IT teams may purchase additional security tools which becomes costly in the long run Need for accurate network performance monitoring metrics • Accurate real-time data can prevent network downtime and security threats • Dashboards don’t always give a clear indication of what to investigate and offer little to no insight into the data to resolve issues • The need for an advanced network monitoring solution to provide an intelligent alerting system that can triggers alerts on deviation from normal performance based on dynamic baselines calculated from historical data Tradeoff Performance
- 6. Ability to scale Provide visibility at higher speeds Removing repetitive data Prevent security attacks As networks expand and speeds increase, network packet brokers (NPB) need to be able to scale and aggregate traffic across multiple networks (LAN, WAN, Internet, virtual and cloud environments) while maintaining layer visibility at all times Network packet brokers with advanced filtering capabilities can organize and streamline data for monitoring, performance, and security tools. NPBs can assure that firewalls and IPSs see exactly the right data, all of the time Network packet brokers will check each packet for redundant data and remove these packets to prevent monitoring tools from being overloaded The real challenge lies in efficiently funneling data from the network to each tool that needs it. An advanced network packet broker can provide 100% visibility for monitoring and performance at speeds of 10G, 25G, 40G and 100G with zero packet loss The importance of network packet brokers
- 7. 5 steps to better network performance monitoring 1. Solve network issues before they become problems: real-time monitoring and setting performance baselines will help network operators solve problems before they happen 2. Implement advanced security and analytics tools: real-time security and analytics tools are essential for detecting and preventing network attacks (DDoS, SSL, DNS) 3. Intelligent monitoring tools: getting the right data to the right tool, at the right place, and at the right time requires sophisticated monitoring tools and a visibility architecture that can access critical data from any network environment: virtualized, on premise, or in the cloud 4. Consolidate existing tools: invest in a network performance monitoring solution that can reduce the number of tools you use to monitor and troubleshoot your network, applications, and infrastructure. Remember, less is more 5. Plan for change: data growth, rise of 100G networks and network infrastructure changes will have an impact on your business. Your network monitoring tools need to be flexible and scalable to adapt to these changes
