What is the function of a hub-and-spoke WAN topology?

With a hub-and-spoke topology, all spoke circuits can share a single interface to the hub. For example, spoke sites can be interconnected through the hub site using virtual circuits and routed subinterfaces at the hub. A hub-and-spoke topology is also an example of a single-homed topology.

What is hub-and-spoke network topology?

A hub-and-spoke network, often called star network, has a central component that’s connected to multiple networks around it. The overall topology resembles a wheel, with a central hub connected to points along the edge of the wheel through multiple spokes.

What are the characteristics of network topology?

A network topology can be one of two types: physical topology and logical topology. Physical topology refers to the physical arrangement of computer nodes based on hardware configuration while logical topology defines how data is flowing through the network. Both topologies exist in a Local Area Network (LAN).

Which topology is used in WAN?

Ring. The ring topology is commonly used on both LAN and WAN networks. With a ring layout, the devices – sometimes referred to as nodes – on the network are laid out in a rough circle.

How does hub-and-spoke work?

The hub and spoke model refers to a distribution method in which a centralized “hub” exists. Everything either originates in the hub or is sent to the hub for distribution to consumers. From the hub, goods travel outward to smaller locations owned by the company, called spokes, for further processing and distribution.

What is the difference between hub-and-spoke?

A hub is a central airport that flights are routed through, and spokes are the routes that planes take out of the hub airport. Most major airlines have multiple hubs.

What are the benefits of the hub-and-spoke system?

The hub-and-spoke model creates numerous benefits, including: Continuous movement for loads thanks to centralized handoffs. Reduced lengths-of-haul, which improve scheduling, reduce transit time and help drivers comply with hours-of-service regulations.

How does hub-and-spoke network work?

A hub-and-spoke network is a route where an airline not only transports passengers between two points but also connects the passengers of distant points via its hub. Such routes are used as spokes connecting other cities via its hub. This model was originated from the U.S. carrier American Airlines.

What is a logical topology?

A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured.

What is a characteristic of a logical point to point topology?

What is a characteristic of a logical point-to-point topology? The nodes are physically connected. The physical arrangement of the nodes is restricted. The media access control protocol can be very simple.

What type of logical topology do they use on their home network?

Star. The star topology, also called spanning tree, is the most common topology used in business networks, and is also very popular with home networks. This is because the star topology is used with the networking technology called Ethernet, which is also very popular.

What are the 4 common WAN topologies?

WAN Topology Types

  • Point-to-Point Topology.
  • Hub and Spoke Topology.
  • Full Mesh Topology.
  • Dual-Homed Topology.
