Topology Network.

Situs-Situs in distribution system earn incircuit [pass/through] assortedly [is] way of which [is] determined pursuant to the following criterions
Expense of installation. Connective expense [of] situs-situs in system
Expense of communications. Big [of] money and time to deliver message from one situs to other situs
Availability / availability. Until how far data can be accessed [by] although there are failure [at] some or link of situs
Kinds of network topology for example:
Fully Connected Network
Every situs in Fully Connected Network terkoneksi directly with other situs. Existing Link become many and cause the expense of big installation. Topology this type of impractical to be applied in big system.
Partially Connected Network
Existing Link only [among/between] some situs so that the expense of installation become lowerly. But, expense of communications can become costlierly. Taking example, A situs wish data access [in] E situs, hence gone through road;street [go] to E situs have to [pass/through] B situs beforehand for no direct link of A situs to situs E. Progressively far gone through road;street, expense of costly communications progressively. Besides, availibilitas or availability of compared to unfavourable data [of] Fully Connected Network. Taking example, if happened site failure or failure of situs [in] C hence accessing to F situs becoming not there [is]
Picture 23.3. Model of Network
Partially Connected Network consist of
Network Tree-structured. Expense of communications and installation [at] topology this type of usually lower. But, if happened link failure or of failure site hence data access become to be pursued and result availibilitas / availability become to lower
Network Star. Expense of low communications because each;every situs at most accessing two link to other situs. But, if/when happened site failure [in] situs center hence each;every situs will not earn to access situs

Partially Connected Network

Network Ring. Expense of high communications because if we like to access a situs it is possible that have to go through many link. For example, from A situs [go] to D situs, link passed [by] the three of fruit. Availibilitas / availibility of [at] topology of ring network more [is] well guaranted compared to [at] network star and also [at] network tree-structured
Besides network topology, there are some something else which must be considered in network mendesain
1
And resolution name Naming. How two process place / positioning one another in communications network.
2
Strategies Routing. How message delivered to [pass/through] network.
3
Strategies Packet. Do package delivered individually or sekuensial.
4
Strategies Connection. How two process deliver message by sekuensial.
5
Contention. How to solve problem natural request [of] conflict
It is important to know, that in distribution system there are is assorted [of] hardware failure ( failure hardware) like failure of or link of failure link, failure of or situs of failure site, and message loss or of loss message.Oleh of in consequence, to guarantee strength of system or referred [as] also robustness hence distribution system have to can [do/conduct] detection of failure, repair system, and configuraton [him/ it] return.
