Scalability in Network Architecture (by Christian Ferenz)

Scalability in Network Architecture

There has been a huge surge in network traffic and no industry is immune from being overwhelmed by data. Network visibility is a requirement for all industries ranging from financial corporations, telecom companies, data centres to retailers, government and healthcare. All are vulnerable to becoming constrained due to scalability issues.

With non-scalable tools, companies are limited by the number of switches and the architecture does not allow them to address all their network visibility concerns. As a result, they end up investing huge sums in changing their entire network architecture.

If a company’s existing network monitoring setup consists of a limited number of network TAPs feeding a monitoring switch, the system provides limited visibility and is not scalable. Such a system is also not capable of addressing regular microbursts in network traffic. Furthermore, the architecture generates substantial duplicate packets that the switch is not equipped to eliminate, creating challenges for monitoring. In such cases, when a company needs to install new TAPs and new port SPANs to accommodate network expansion, the old switch is not able to handle the load.

A scalable solution which offers multi-stage filtering, de-duplication and other features helps a network operate more efficiently.

Customers can ease these problems by building scalable network monitoring visibility solutions.

  • Tools that can intelligently aggregate data and precisely channel it to the appropriate monitoring tools without missing or dropping data, and which provide 100-percent visibility. Instead of using several TAPs, SPANs and tools, a scalable tool can provide 100 percent visibility of all data passing through it.


  • With a scalable solution, it is easy to add ports to handle the change in network traffic. Network expansion is easy to accommodate if there is room to add more ports. A solution that consists of small boxes with a low port count might serve a momentary need, but in the process of fixing one problem complexity has been added to the network.


  • As networks move from 1G to 10G speeds; and from 40G and 100G speeds; data centres will need new hardware if the ports on their monitoring switches aren’t able to handle the increase. This can cause network unavailability which can lead to dropped packets and loss of visibility. Network engineers need tools which provide an easy path to migrate to future high-speed technologies.

Conclusion :

Scalability and simplicity seem to go hand-in-hand. An elegant, well-designed network architecture makes scalable network monitoring possible. Reliable network packet brokers enable cost-effective network traffic scaling. With these network packet brokers, customers benefit from cost-effectiveness, scalability, and flexibility. The advanced NPBs offer centralized visibility architectures that ensure high performance, scalability, and advanced traffic optimization features.

CEO Cubro ChristianAuthor - Christian Ferenz - started his entrepreneur journey as a measurement instrumentation distributor in 2003 and soon realized that there was a market for producing better network monitoring solutions. Along with some of his business partners, Christian established Cubro Acronet and started developing TAPs and Packet Broker lines. Within few years, the company spread its wings in the international market.

Today Cubro is among the leading vendors of TAPs and Network Packet Brokers and partner to the world’s largest Telcos and Enterprises with installations on all continents.
