As it is clear from the name of this protocol, the idea behind Transport layer is in delivering data. It is not the only function of this layer but delivering is essential. Transport layer ensures successful delivery in correct order, without errors. Data is being verified by the recipients Transport layer. Its integrity should be exactly the same as on senders end. ...
Two different nodes in the network are connected to each other communicating. Meanwhile, it is the job of the Session layer to maintain and coordinate communications between them. While “session” means the data exchange between two workstations, the task of the Session layer is more in managing than transferring data. We would use term “session” as a connection between client ...
As it is known, every level in OSI model communicates with levels that are below and above it. The task for the presentation layer is to receive data from the application layer and translate it so application on the other side of connection would understand it. It converts the non-text data like images, pictures, photos, sounds, music, and videos to ...
The top layer of OSI model is the application layer. This layer is created for translating software or application commands and requests to language familiar to low-layer network services. The software sends security, procedural, synchronization requirements. Some of the requirements that can not be executed by Application layer are being forwarded down the OSI, while others being executed.
Figure 1. Application ...
The OSI (Open Systems Interconnection) networking model has been developed by ISO as a standard and universal set of specifications that would help and simplify communication between computers through the network.
The OSI networking model is splitting network communication into seven layers. Each layer has different protocols designed to perform specific tasks while interacting only with layers below and above.While top ...
Management of the small size network is possible by single network administrator. He/she could simply get access to any workstation or server in the network physically since it is located nearby. Addressing conflict problem could be quickly located and solved.
Modern networks are big and growing very fast which makes their management a complex task. In order to help network administrator, ...
It is clear that networks provide benefits over using single machines by sharing resources, having secure connection, remote control, etc. Network equipment can be divided in three main parts that are necessary for successful network operation.
First part is the equipment, located at the end of the lines. It includes client, server, workstation. You can read more about Client Server Definition ...
Nominal central wavelengths for coarse WDM systems
CWDM grid wavelengths within the range 1270 nm to 1610 nm are shown below. The value of "c" (speed of light in vacuum) that should be used for converting between wavelength and frequency is 2.99792458 x 108 m/s
For ordering CDWM XFP transceivers, you case use this reference table:
Can I use single mode equipment over multimode cable and vice versa?
This is a question we get many times from our customers. Especially common is a situation, in older installations, back to the times when multimode cable was cheaper than single mode, and inside buildings, and some last mile installations were planned so, that multimode cables were laid.
Answer is not ...
