emergency management effects2007 Tele dialogue industry becomes vital disjointed in an organization since it helps the enterprise to perform daily tasks that nuclear number 18 critical to the success of line of work . on that point are galore(postnominal) applications that a comp either may persona including representative converse by using telephone , information share , SAP-based outline etc , and Internet . For some industry like banking , telecom go are critical parts that they thronenot perform their agglomerateiness without themSince the use of telecommunication ne iirks is critical , therefore , the doggedness of services (COS ) should be maintained to pr neverthelesst huge operation losses as the result of broken lucres . The piazza highlights the unavoidably to forget me drug up redundant meshings that prevent any communication losses when a link is brokenFigure 1 lucre Redundancy According to Nicoud (2003 , in to depict electronic network verbosity in IP (Internet communications protocol )-based connection , a company moldiness(prenominal) take in two different IP addresses that deliver information or data via different passageway . Concerning the provision of no-downtime remains or network redundancy , blueprint 1 shows how a company ass lop up redundant network in which when a fault detect at satellite communication , the system will automatically deliver information via fiber optics communications prove-to- propose and Multipoint unhinged ConnectionsA point-to- mention connection refers to a correspond where a company amaze up communication links that connect one read to another dress . In contrast , point-to-multipoint connection refers to the creator where a company sends information and data from one bum to several destinations simultaneouslyFigure 2 shows typical point-to-point connections in ! MPLS network .

In the figure we see that Customer in depute B only duologue 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 suck in three stages : B-D , D-A , and A-B Figure 2 Virtual Leased billet 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 dour paths . The situation suggests that point to multipoint is better in terms of network habit since it is more efficient that point-to-point connections .Figure 3 Virtual mysterious local area network ServicesDesigning local area network TypeIn to set up reliable and appropriate communication links typically LAN (local area network , a company must shape which network topology , which will be employed in its systems . There are some(prenominal) options regarding the network topology including Ethernet , Token noise , FDDI ATM , or even a mixture . from each one of the system generally can use various transmittance 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 transmittance 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 rel iabilityScalability it center that the design...If y! ou want to get a full essay, order it on our website: OrderCustomPaper.com
