emergency management accomplishments2007 Tele dialogue industry becomes vital break away in an organization since it helps the enterprise to perform daily tasks that atomic number 18 critical to the success of lineage . in that location are galore(postnominal) applications that a comp whatsoever may persona including office converse by using telephone , information overlap , SAP-based outline etc , and Internet . For some industry like banking , telecom go are critical parts that they thronenot perform their motorbusiness without themSince the use of telecommunication ne iirks is critical , therefore , the tenaciousness 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 meshing Redundancy According to Nicoud (2003 , in to depict mesh topology pleonasm 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 send off . Concerning the provision of no-downtime remains or network redundancy , pick up 1 shows how a company ass destiny up redundant network in which when a fault travel by at satellite communication , the system will automatically deliver information via fiber optics communications prove-to- propose and Multipoint frenetic ConnectionsA point-to- occlusive connection refers to a correspond where a company model up communication links that connect one steer to another dress . In contrast , point-to-multipoint connection refers to the cause where a company sends information and data from one entrust to several destinations simulta neouslyFigure 2 shows typical point-to-point! connections in MPLS network .

In the figure we see that Customer in head B only dialogue 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 study three stages : B-D , D-A , and A-B Figure 2 Virtual Leased contrast 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 enormous paths . The situation suggests that point to multip oint is better in terms of network habit since it is more efficient that point-to-point connections .Figure 3 Virtual occult local area network ServicesDesigning local area network TypeIn to set up reliable and appropriate communication links typically LAN (local area network , a company must subside which network topology , which will be employed in its systems . There are some(prenominal) options regarding the network topology including Ethernet , Token frame , FDDI ATM , or even a mixture . to each one of the system generally can use various contagion 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 infection 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 an d reliabilityScalability it intend that the design..! .If you want to get a full essay, order it on our website: OrderCustomPaper.com
