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. (more…)

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? (more…)

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. (more…)

In previous posts, Sales Engineer, Zach Sherman has explained what SSH, SSL, HTTPS, and RADIUS are while also explaining how these authentication processes are vital to maintaining network security. In this edition, Zach will cover another protocol related to network management and security: ACL rules. An Access Control List (ACL) is literally a list that permits or denies access to networking equipment. In terms of the ION management module (IONMM), it is best to think of an access control list in terms of having an ‘allow’ or a ‘deny’ statement with no middle ground. You are either in, or you are out. (more…)

At Transition Networks we’ve always tried to help our customers integrate fiber optics into their copper-rich cabling environments via media conversion.  Media converters have been a vital tool to traditional enterprise networks for many years.  These converters have allowed organizations to experience the benefits of fiber cabling..
