Troubleshooting Wireless Networks
What's the difference between an edge router vs. core router?
Clearly, an edge router and core router are placed in different parts of the network, but their routing roles are more complex than their physical locations. Continue Reading
What are private 5G networks and could they emerge as a major trend?
In some network environments, businesses may need broader connection options for devices and automation. Private 5G networks, at some point, might be the answer. Continue Reading
A glossary for the terms and types of WAN technologies
This introduction to WAN technologies defines several different terms -- such as VPN and SD-WAN -- that are essential in anybody's networking vocabulary. Continue Reading

network operating system (NOS)
A network operating system (NOS) is a computer operating system (OS) that is designed primarily to support workstations, personal computers and, in some instances, older terminals that are connected on a local area network (LAN). Continue Reading
Wireless capacity more important than fast Wi-Fi 6 speed
Wi-Fi 6 speed may be getting all the attention, but the most compelling advantages of the new standard are techniques engineered to increase wireless capacity. Continue Reading
SD-WAN with IoT enables the enhanced network edge
In a world teeming with IoT devices -- and the resulting data -- SD-WAN and SD-branch can provide the security, visibility and connectivity the IoT edge requires.Continue Reading
What are the 5 types of network firewalls and how are they different?
As they monitor and filter network traffic, some firewalls can provide some pretty advanced security controls. But added packet inspection can slow network performance.Continue Reading
network packet
A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network.Continue Reading
local area network (LAN)
A local area network (LAN) consists of computers and peripherals that share a common communications line or wireless link to a server. LANs are typically located within a distinct geographic area in an office or other facility.Continue Reading
What is a programmable data plane and where does P4 fit in?
A programmable data plane presents a versatile way to forward packets and supports various formats and protocols. The P4 language is used to configure the forwarding actions.Continue Reading

client-server model (client-server architecture)
Client-server is a relationship in which one program (the client) requests a service or resource from another program (the server). At the turn of the last century, the label client-server was used to distinguish distributed computing by personal ...Continue Reading
What you need to know about edge computing architecture
Edge computing makes network operations more responsive, but there are challenges that must be addressed to get this latest network architecture working for you.Continue Reading
What happens when edge computing hits enterprise networks?
Is it time to take your network to the edge? Learn what edge networking can do to improve traffic flows, ease demand for high-performing connectivity and more.Continue Reading
