How to create VLANs with Grandstream GWN7800 series switches

Posted by Guest Blogger on Jul 5, 2023 10:30:00 AM

By Brian Van Meter at Grandstream

As technology continues to advance, networks within offices, hotels, education spaces and other verticals have grown more complex. Phones, computers, IoT devices, smart technology and more can all be simultaneously running across a deployment’s Local Area Network (LAN). This can lead to issues with security, network organization, and scalability.

As a result of these roadblocks, Virtual Local Area Networks (VLANs) have become an increasingly popular feature that can help partition physical networks into virtually manageable ones. Within this blog post, we’ll give you an introduction to building VLANs with Grandstream’s GWN layer 2+ switches.

The Magic of Power over Ethernet (PoE)

Posted by Daniel Noworatzky on May 13, 2020 10:51:00 AM

Most modern IP phones today support Power over Ethernet (PoE), an almost magical technology that powers your IP phone via the same Ethernet cable that connects it to the network. While it may seem simple on the surface, PoE technology is actually quite sophisticated, and is worth understanding when making choices involving network design or IP telephony hardware.

SDN: The cutting edge of network design

Posted by Daniel Noworatzky on Oct 9, 2019 10:50:00 AM

A major challenge inherent in designing and maintaining an enterprise network is the administration costs. Software-defined networking (SDN) can dramatically reduce both the hard costs (money) and soft costs (time) of managing a network. Although this tends to be the most compelling argument in favor of using SDN, it in fact offers may more advantages than this. In this article, we introduce SDN and examine some of its key benefits.

Spotlight on Cisco

Posted by Daniel Noworatzky on May 1, 2019 10:50:00 AM

Cisco is a name familiar to almost anyone who has worked in networking or telecommunications over the past few decades. Founded in the mid-1980s, it pioneered some of the most fundamental concepts in networking, including LANs, WANs, and multiprotocol routing. In this article, we take a closer look at Cisco and its cutting-edge networking and telecommunications solutions.

Quality of service must-haves for converged networks

Posted by Daniel Noworatzky on Nov 7, 2018 10:49:00 AM

IP Telephony features are not always “plug-and-play.” Rather, they must be configured to function properly. This is equally true when dealing with quality of service (QoS) on a network that transmits both data and voice (i.e., a converged network).

Companies commonly find that when they install their VoIP system on a preexisting data network, it works great at first. Days or weeks later, however, users complain of poor voice quality and intermittent disconnections. The network has not changed, so what’s going on?

In this article, we’ll see why QoS is a fundamental part of your network design for voice, and examine five configurations that should always be employed to achieve high-quality voice on a converged network.

QoS for VoIP networks: IntServ versus DiffServ

Posted by Daniel Noworatzky on Oct 17, 2018 10:48:00 AM

Your customer using a legacy phone system decides to switch to voice over internet protocol (VoIP). They install an IP PBX and buy some IP phones. Great, they’re all set, right? Wrong. Without configuring their data network for quality of service (QoS), they will experience a severe deterioration in voice quality and may regret making the decision to switch. Yes, the IP PBX and the IP endpoints will already be configured for QoS. But what about other parts of the network like the pre-existing routers, switches and firewall? All it takes is one missing link for the whole system to be compromised.

QoS is a big topic. In this article, we’ll look at two main approaches to QoS: IntServ and DiffServ, their strengths and limitations, and when to use which one.
