What is backbone network explain?
A backbone or core network is a part of a computer network which interconnects networks, providing a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas.
What are the basic backbone network components?
Backbone network components (Data Communications and Networking) There are two basic components to a BN: the network cable and the hardware devices that connect other networks to the BN. The cable is essentially the same as that used in LANs, except that it is often fiber optic to provide higher data rates.
What is backbone network in deep learning?
Backbone is a term used in DeepLab models/papers to refer to the feature extractor network. These feature extractor networks compute features from the input image and then these features are upsampled by a simple decoder module of DeepLab models to generate segmented masks.
What is the most common backbone architecture used within a building?
Switched Backbones
Switched Backbones: most common type of backbone, used in distribution layer, used in new buildings, sometimes in core layer, can be rack or chassis based. Replaces the many routers of other designs – Backbone has more cables, but fewer devices.
What is the uses of backbone?
Backbone is most important part of a system which provides the central support to the rest system, for example backbone of a human body that balance and hold all the body parts.
Which topology uses a backbone?
bus topology
A bus topology exists when all of the nodes on the network are connected to a single cable. This single cable is commonly referred to as a backbone. Bus topology was used for early 10Base-2, ThinNet, and 10Base-5, ThickNet, coaxial cable Ethernet networks.
Which topology is used in telecom network?
In a star topology, network nodes are directly connected by point-to-point links to a central node, usually called a hub, as shown in Figure 11.7a. Typically, each node requires two links to connect to a central hub, one for transmission and one for reception.
Why are kernels of different sizes used in Googlenet architecture?
The idea is that with a given convolutional receptive field, multiple stacked smaller size kernel is better than the one with a larger size kernel because multiple non-linear layers increases the depth of the network which enables it to learn more complex features at a lower cost because it has lower number of learning …
What is backbone in segmentation?
The backbone and the segment are important concepts in network design, although the two are only loosely related. A backbone, on the other hand, is a high-bandwidth link used to carry traffic between networks or over physically large distances. Some network designs have individual segments connected by a backbone.
How does data communication and computer network work?
Data Communication and Computer Network 1 A system of interconnected computers and computerized peripherals such as printers is called computer network. This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media.
What makes up a field level communication network?
These networks consist of parallel, multiwire cables as transmission medium. The common serial communication protocol standards used in this level include RS232, RS422 and RS485. There are many other field level communication networks available which are characterized different factors such as response time, message size, etc.
Which is the most common industrial communication network?
Commonly used Industrial Networks. Serial Communication. HART: DeviceNet. ControlNet. Modbus. Profibus. Foundation Field Bus. An industrial communication network is a backbone for any automation system architecture as it has been providing a powerful means of data exchange, data controllability, and flexibility to connect various devices.
How are communication networks used in manufacturing industry?
In a manufacturing or process industry, the information or data flows from field level to enterprise level (bottom-to-top) and vice-versa. Different levels have to handle different requirements of a particular level. So it is obvious that no single communication network address requirements needed by each level.
