Cable operators all around the world are working hard to provide their customers with high speed data services by making use of (Euro)DOCSIS® 3.0 technology. An important problem however is that as of today none of the available CMTS solutions are EuroDOCSIS™ 3.0 Qualified. As an operator you want...
byteblower.intro_.jpg One, single solution, endless possibilities The ByteBlower network traffic generator/analyzer tool helps you perform exhaustive tests on IP networks and networking equipment. The possibilities are endless. Focused on performing tests up to layer 5 of the OSI model, including...
Excentis offers a unique testing service in a real home — a realistic, static, residential environment with controllable interference. This setting enables the customer to statistically compare Wi-Fi access points, as the performance is measured by a robot from different physical locations in the...
home_gateway.jpg Cable operators are now deploying advanced home gateways instead of simple cable modems. New advanced services, the transition to IPv6 and the ever increasing number of connected devices push such gateways to support a multitude of services and devices — fundamentally increasing...
Excentis also offers large scale CMTS testing. We have a setup in use with more than 500 Cable Modems to verify the stability and performance of your CMTS, also long term (order of weeks). The configuration options are countless, here are some examples: All Cable Modems are connected to ByteBlower...
When talking about throughput, all sorts of numbers get tossed around. However, it is crucial to clarify what data you are talking about when demonstrating and comparing values. What’s included, and what’s not?
Rigorously testing a network device or distributed service requires complex, realistic network test environments. Linux Traffic Control (tc) with Network Emulation (netem) provides the building blocks to create an impairment node that simulates such networks. This first post of a three-part series, introduces both.
Rigorously testing a network device or distributed service requires complex, realistic network test environments. Linux Traffic Control (tc) with Network Emulation (netem) provides the building blocks to create an impairment node that simulates such networks. This second post of a three-part series shows which impairments are available and how they can be configured.
Rigorously testing a network device or distributed service requires complex, realistic network test environments. Linux Traffic Control (tc) with Network Emulation (netem) provides the building blocks to create an impairment node that simulates such networks. This final post of a three-part series shows how to set up an impairment node in practice.
This blog post helps you solve common issues you may encounter when testing Network Address Translation (NAT) routers, or devices behind NAT routers.
