For this blog, I interviewed Kevin Przybocki, one of Anue Systems’ founders. We talked about Long Term Evolution (LTE.)
If you watch even a modest amount of TV or Hulu, it’s likely you’ve heard about 4G. Mobile carriers talk about 4G networks quite a bit in TV ads because it’s 10 times faster than the predecessor – 3G networks. A type of a 4G wireless network, known as LTE, is used by Mobile Carriers to deliver the next step in user experience. You can read up on the technical details here. Although there is some quibbling about 4G requirements, this will be solved with a future release called LTE Advanced.
In any case, according to Kevin, the average Mobile customer does not care about the technical details – they care about Quality of Experience (QoE). We do care about Service Level. It is a benefit that LTE is 10 times faster, but we don’t want to have service quality problems such as dropped calls or not being able to stream videos – no matter how many G’s are associated with the service.
So Kevin believes this is where companies like Anue come into play. What we provide is a network monitoring switch– an innovation in network management and monitoring –that allows performance monitoring tools to get exactly the right network data they need for analysis. With the network monitoring switch, Mobile carriers can aggregate information across scarce network ports, and define and filter data required for analysis to large numbers of performance and security monitoring tools.
The network monitoring switch’s “magic sauce,” according to Kevin, is that it filters the data and de-duplicates redundant packets. This is critical for effective and efficient data analysis and troubleshooting – instead of being flooded with data packets that may or may not apply to its interests, the monitoring tool gets just what it needs. If the tool is monitoring VoIP, it only gets VoIP traffic versus everything else that might be traversing the network segment.
Kevin points out another interesting feature of a network monitoring switch = its capability to load balance, which is particularly handy as carriers move to Higher Speed Ethernet (HSE). Whereas today most networks run on 1G or 10G networks, the future is 40G/100G networks. This introduces the problem of not being able to monitor HSE networks because the tools haven’t been developed yet. With the network monitoring switch, you can perpetuate the life of your existing tools by allowing them to share the load of the higher speed networks.
The dogs illustrate load balancing. And as Kevin pointed out, the stick represents a HSE network that neither dog would be capable of carrying on its own. Moving away from the dog analogy, the network monitoring switch allows multiple tools to share monitoring workload, so even 1G/10G-capable tools can work together to provide monitoring for 40G networks, for example.
This concludes my interview of Kevin, which gives you a high level overview of a network monitoring switch and how it can help Mobile carriers keep up with increasing demands and expectations from customers with changing network technologies.
