In the end, you'll learn something and understand it better. If possible, grab a consultant or trusted VAR of your networking equipment (their sales engineers are often happy to help) and work out the best setup for your shop.

As they are a combination of other topologies, there is a large variation in what a hybrid can look like. There are also hybrid network topologies, which are a combination of two or more topologies. Load it up with the same firmware and config as the primary switch and if that switch fails or has issues just physically swap in the cold spare.īut your question sounds like you could be in over your head a little. There four main types of network topologies: Bus topology.

make your "redundant switch" simply your cold spare.

It's not a hard thing to get setup, but it will take some planning and decent knowledge on how VRRP works.Ī "cheap" alternative based on your pics is: That takes some pretty decent networking knowledge and the switches have to support such a setup. If you can't stack them, then what you are proposing in your proposal pic is more like VRRP or similar. You would have the same LAG groups but with ports on each physical switch and then a 2 port LAG to the router at the top. In such a case, each node is connected to a router to form a Star network and then the routers will be connected together to create a Bus connection between them.If you can "stack" the 2 proposed "core switches", that would be the easiest thing to setup and would allow for "redundancy. This is often used when there are several clusters of nodes such as in a WAN. Most networks combine one or more different topologies to create a hybrid. Using Mesh networks, resilient smart homes, smart businesses and smart cities become a real possibility. It also improves range as node A may be out of direct range with node C, but the message may still get through via node B. These are only really implemented in, for example, military networks where 100 redundancy is essential.īeing connected to multiple other nodes adds resilience, as there is no single point of transmission failure.

In a full Mesh network, each node is connected directly to every other node. Redundancy In Network Topology Full Mesh Network It also relies on devices being within a certain distance of the hub. If the hub fails, the entire network ceases to exist, leaving devices unable to communicate at all. The hub at the center of the system is a single point of failure. Star networks are highly suitable for connecting both wired and wireless nodes together seamlessly.

This is similar to a Linear topology but with a single line having multiple single branches. The daisy chain is also susceptible to errors as a single failing node may cause massive disruptions, and in worst case cause messages not to come through at all. If two nodes that are on opposite sides of a 1,000-node ring want to communicate then their data has to be passed through 500 other nodes first. Its a simple method but quickly becomes impractical as you add more nodes.Įach further node is added in between two existing nodes to create a loop.ĭata is transmitted around the ring, either in one direction or both, and each node examines the data and acts on it or retransmits it until it reaches its destination.

Whether its a router, a smartphone, Bluetooth headphones or smart light bulbs, each device on a network is known as a node.Ī modern example would be the kind of ad-hoc connections made via Bluetooth for things like file sharing service or remote control of e.g. Redundancy In Network Topology Bluetooth Headphones Or
