There are galore(postnominal) applications that a company may persona including voice converse by using telephone , information sharing , SAP-based outline etc , and Internet . For some industry like banking , telecommunication go are critical parts that they thronenot perform their business without themSince the use of telecommunication ne iirks is critical , therefore , the continuity of services (COS ) should be maintained to pr neverthelesst huge operation losses as the result of broken lucres . The piazza highlights the needs to forget me drug up redundant meshings that prevent any communication losses when a link is brokenFigure 1 Network Redundancy According to Nicoud (2003 , in to depict network redundancy in IP (Internet communications protocol )-based connection , a company must(prenominal) take in two different IP addresses that deliver information or data via different route . Concerning the provision of no-downtime remains or network redundancy , figure 1 shows how a company ass set up redundant network in which when a fault happen at satellite communication , the system will automatically deliver information via fiber optics communications prove-to- propose and Multipoint mad ConnectionsA point-to-Point connection refers to a correspond where a company set up communication links that connect one designate to another dress . In contrast , point-to-multipoint connection refers to the condition where a company sends information and data from one place to several destinations simultaneouslyFigure 2 shows typical point-to-point connections in MPLS network .

In the figure we see that Customer in Point 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 have three stages : B-D , D-A , and A-B Figure 2 Virtual Leased cable 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 long 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 Private local area network ServicesDesigning LAN TypeIn to set up reliable and appropriate communication links typically LAN (local area network , a company must decide which network topology , which will be employed in its systems . There are some(prenominal) options regarding the network topology including Ethernet , Token Ring , FDDI ATM , or even a mixture . Each of the system generally can use various transmission 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 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 means that the design...If you want to get a full essay, order it on our website: Orderessay
