Devy Blog

Finally able to update the article again. I have not updated my blog, because the workload is so much made ​​me not have time to update my blog. Okay, straight into the writing course yes. I will discuss about the MAN (Metropolitan Area Network).

Metropolitan Area Network (MAN) is basically a LAN version of the larger size and usually use the same technology to the LAN. MAN could include corporate offices are adjacent and can be used for private purposes (private) or public. MAN mamapu usually support data and voice, and can even be connected with a cable television network. MAN only have one or two buiah cable and do not have the switching element, which serves to regulate cable package through multiple outputs. The existence of switching elements make the design becomes simpler.

The main reason for separating the MAN as a special category is already fixed by the standard for MAN, and this standard is now being implemented. Standart is called DQDB (Distributed Queue Dual Bus) or according to standard IEEE 802.6. DQDB consists of two unidirectional cable where all computers are connected, as shown in Figure 1.2. Each bus has a head-end device to initiate the transmission activity. Traffic leading to computers that are on the right of the sender using the bus top. Traffic to the left using the bus at the bottom.

That’s a bit of my writing about the MAN (Metropolitan Area Network). I hope my writing can be useful for all my friends. good luck
