A multilayer switch is a network device that has the ability to operate at higher layers of the OSI reference model, unlike the Data Link Layer (DLL) traditionally used by switches. A multilayer switch can perform the functions of a switch as well as that of a router at incredibly fast sp...
In general, it's best to avoid free VPNs altogether. By choosing a paid provider, you are choosing a real and credible company, backed by quality technology and infrastructure. A paid provider is also less likely to log your activities and sell that information to advertisers. A premium VPN...
Label switch routers (LSRs) interpret the MPLS labels -- not the full IP address of any traffic. MPLS forwards data packets to Layer 2 of the OSI model, rather than passing to Layer 3. For this reason, MPLS is informally described as operating at Layer 2.5....

I've read many IP routing examples where a single Layer 3 switch is used as the router in a network environment where all other switches are operating just at Layer 2. That's fine, I understand that. However, what about if one has many Layer 3 switches? Does one (a) simply choose ...
The most prevalent technique for software to harness the power of multicore CPUs remains horizontal scaling, which is implemented by running multiple copies of a software component, typically encapsulated in containers and virtual machines (VMs), across one or more physical machines. ...
Are an Ethernet switch and hub the same? No. While they are both examples of data network hardware, a hub is a Layer 1 device, which is part of the physical transport layer and acts as a broadcast/aggregator but does not manage any of the traffic. ...
coli is dependent on an invertible promoter element, fimS, which serves as a phase variation switch determining whether or not a bacterial cell will produce type 1 fimbriae. In this review, we present aspects of signaling and stress involved in mediating regulation of type 1 fimbriae in extra...
What Is Switch Virtualization Technology & What Are Stacking and M-LAG, What Are Their Differences This document describes the concepts of stacking and Multichassis Link Aggregation Group (M-LAG), their functions on the network, as well as their differences. Overview What Are Stacking and M-LAG...
A standalone switch is managed and configured with a set capacity. Stackable switches can be connected to increase capacity and network availability. For configuration, troubleshooting, and management, a stack of switches can be treated as a single unit. If any part of the stack fails, transmissi...
