Layer 1 Network Diagram

At layer 1 the physical layer of the osi model is responsible for the ultimate transmission of digital data bits from the physical layer of the sending source device over network communications media to the physical layer of the receiving destination device. It s also a good idea to make a separate diagram for each network protocol layer. Hardware the things you can actually physically touch exist at layer 1 physical.

Layer 1 network diagram. A network diagram showing layer 2. Network diagram and visio layers 1 2 par ttrupel le 27 03 2016 16 59 in this first article we show you how to take advantage of visio layers to display different network informations l1 l2 l3 routing configuration on the same sheet without overload the network diagram. I usually start with a layer 3 network diagram to show the routing and ip subnets. The pdu is passed to layer n 1 where it is known as the service data unit sdu.

Layer 1 consists of the various networking hardware and transmission technologies being employed by networks. It is then passed to layer n 2. After that comes a layer 1 diagram showing physical layouts of the devices. Drawing overlay network layers 14th march 2014 network diagrams.

Then i make a layer 2 diagram showing the switch connections trunks and lacp channels. In short layer 2 allows the upper network layers to access media and controls how data is placed and received from media. Also known as the network layer l3 is an abstraction layer that deals with packet forwarding through intermediate routers. Physical layer 1 osi model layer 1 conveys the bit stream electrical impulse light or radio signal through the network at the electrical and mechanical level.

At layer n 1 the sdu is concatenated with a header a footer or both producing a layer n 1 pdu. This layer converts the binary from the upper layers into signals and transmits them over local media. Choosing better and free fonts 10th january 2014 my new diagram colour scheme old disco style 24th september 2013 on diagrams and information 10th september 2013. This layer is the first and serves as the foundation the fundamental layer underneath the logical data structures of other higher level network functions.

Layer 2 data link examples include ppp fddi atm ieee 802 5 802 2 ieee 802 3 802 2 hdlc frame relay. In the open systems interconnection osi model logical network diagrams correlate with the information contained in layer 3 l3. Layer 1 is the first layer of the open systems interconnect osi model. The process continues until reaching the lowermost level from which the data is transmitted to the receiving device.
