There is no doubt that you are all familiar with QoS or Quality of Service – basically a set of provisions set up on the network to prioritize certain applications, users, or data flows to guarantee a set level of performance. Often times when we talk Quality of Service, two other terms come up as well. Those are Class of Service (CoS) and Type of Service (ToS). To the uninitiated, these two terms may appear to be describing the same thing. Through the course of this post, we will try to define each term and specify where each comes into play.

The IEEE Power & Energy Society recently held its annual General Meeting on July 25th – July 29th, in Minneapolis, MN. The topic of this year’s meeting was: “Power Systems Engineering in Challenging Times”. Being a member of the IEEE and having the event in our backyard this year offered the opportunity for Chris Koch, a Principal Architect at Transition Networks, to attend this multi-day event.

As Transition Networks continues to expand its broad industrial portfolio, we are offering more and more fully-hardened Ethernet switches and media converters with certifications required for many varied vertical industries.
Recently, our High Port-count Industrial Managed switch, SISTM1040-262E-LRT, received GL Certification. Now, I know that we have all heard the term “GL Certified” used before. But what exactly does it mean? Read the rest of this entry »

We at Transition Networks are often asked, “Can I use a standard ZX or ZR optic on the 1550nm port of one of your CWDM multiplexers?” The truth is that you may be able to, but we never recommend attempting to do so. Here is a little background on why that is: Read the rest of this entry »

As networks are asked to carry increasing amounts of delay-sensitive traffic like VoIP and IP video, administrators have been forced to utilize Quality of Service (QoS) techniques more and more often. QoS is used to increase a network’s reliability and speed, by prioritizing particular network traffic over other traffic. Quality of Service methods can really be split into two main QoS categories: Hard and Soft QoS. The remainder of this post will take a look at each of these methods. Read the rest of this entry »
