The Many Flavors of SD-WAN


Choosing SD-WAN is a no-brainer for many enterprises. It provides them with greater flexibility and control, and the agility to succeed in today’s fast-paced world. But given the large number of SD-WAN vendors and service providers flooding the market, which flavor of SD-WAN to purchase is a much tougher decision.

5G Fronthaul network impairment testing using the Calnex A100

The Calnex A100 was designed with SyncE in mind and supports both SyncE pass-thru and synchronisation to external clock references, as well as the 25GbE and 10GbE interfaces that fronthaul requires. The Calnex A100 can also filter on, and impair, specific eCPRI and RoE message types thereby helping engineers understand how eCPRI and RoE behave in a real fronthaul network.

Network Emulation and Satellite Communications

As the growth of satellite communications accelerates, organisations across the globe are turning to network emulators to ensure quality of service prior to deployment.

The Value of Network Impairment Testing in Power Grids

The nature of power utilities networks is that they are increasingly reliant on the use of communications networks. Moreover there is a growing trend to move away from legacy technologies (in this case Time-Division Multiplexing or TDM) and adopt packet-based (TCP/IP) networks.

What's wrong with our Network?

Application performance issues are a frustration most enterprises will likely suffer – 89% of business executives say that poor application performance negatively impacts their business on a regular basis, according to the Riverbed Application Performance Survey.

Managing the Costs of Network Monitoring
