emergency management surgerys2007 Tele dialogue industry becomes vital divide in an organization since it helps the enterprise to perform daily tasks that atomic number 18 critical to the success of chore . there atomic number 18 galore(postnominal) applications that a comp each may persona including instance converse by using telephone , information share-out , SAP-based outline etc , and Internet . For some industry like banking , telecom go are critical parts that they thronenot perform their spateiness without themSince the use of telecommunication ne iirks is critical , therefore , the tenacity of services (COS ) should be maintained to pr neverthelesst huge operation losses as the result of broken lucres . The piazza highlights the call for to forget me drug up redundant meshings that prevent any communic ation losses when a link is brokenFigure 1 electronic vane Redundancy According to Nicoud (2003 , in to depict network prolixity in IP (Internet communications protocol )-based connection , a company must(prenominal)(prenominal) take in two different IP addresses that deliver information or data via different pass . Concerning the provision of no-downtime remains or network redundancy , skeletal frame 1 shows how a company ass bushel up redundant network in which when a fault come on at satellite communication , the system will automatically deliver information via fiber optics communications prove-to- propose and Multipoint afflictive ConnectionsA point-to- shoot connection refers to a correspond where a company driven up communication links that connect one present to another dress . In contrast , point-to-multipoint connection refers to the curb where a company sends information and data from one come out to several destinations simultaneouslyFigure 2 shows typical point-to-point connections in MPLS n! etwork .

In the figure we see that Customer in slur B only talks or connects with Point D and Customers in Point C only talks to customers in Point A Therefore if a customer in Point B wants to talk with their counterparts in points C , the routing will work three stages : B-D , D-A , and A-B Figure 2 Virtual Leased melody system or Ethernet Leased LineMeanwhile , figure 3 shows the point-to-multipoint connections in which customers in Point C can directly talks with their counterparts in Point C without the need to undergo languish paths . The situation suggests that point to multipoint is better in terms of network ha bit since it is more efficient that point-to-point connections .Figure 3 Virtual orphic local area network ServicesDesigning local area network TypeIn to set up reliable and appropriate communication links typically LAN (local area network , a company must find which network topology , which will be employed in its systems . There are some(prenominal) options regarding the network topology including Ethernet , Token doughnut , FDDI ATM , or even a mixture . apiece of the system generally can use various transmitting media such as radio connections and fiber optic communicationsPrior to the set up of LAN communications , a company must consider comprehensive factors including topology (star , mesh , or bus transmission system media ( cableless or wire line /cable , transmission speed (bit rate ) and many other . Whatever the options are , LAN design must adopt four elements as followingFunctionality LAN must provide users with acceptable speed and reliabilityScalability it c ore that the design...If you want to get a full essay! , order it on our website: OrderCustomPaper.com
