Visualizing the Network with NMS

Network management systems (NMS) are applications that allow administrators to manage independent software and hardware components of a network. The key benefit of NMS is to make widely dispersed network assets manageable from a single location.

Implementing Quality of Service for Prioritizing Network Traffic

Quality of Service (QoS) is a networking mechanism that helps control and prioritize traffic so that more critical traffic can be sent first on the network. This feature helps ensure performance for critical network traffic. QoS is especially useful in Intelligent Transportation Systems where it helps solidify Signal Controller communication in high volumes of local video traffic.

More Power over Ethernet Features and Applications

With the release of the 802.3bt standard in January of 2019, there are now eight classes of PoE power delivery. PSE stands for Power Sourcing Equipment, and is the device that provides the PoE power. This is most often an Ethernet switch, but there other types of devices that can deliver PoE. “PD” stands for Powered Device and is the device receiving the PoE, such as a VoIP phone, camera, or wireless access point.

Configuring Layer 3 Routing on EtherWAN Switches

In a previous article we discussed the differences between Layer 2 and Layer 3 switches. Layer 3 switches now often support unicast and multicast routing, and even the Virtual Router Redundancy Protocol (VRRP). Depending on the size, configuration, presence of multicast devices, and external connections, different routing methods may be needed.
