Running head: PATTON-FULLER COMMUNITY HOSPITAL (PFCH)
Patton-FullerCommunity Hospital (PFCH) Network Design Proposal
Recommendationsfor changes in the Patton-FullerCommunity Hospital (PFCH) Network
Inthis design the most important changes that Patton-FullerCommunity Hospital (PFCH)need to implement on its network typology is the dimensioning of thetraffic engineering and survivability. Planning for new changes onthe network typology entails determining the topological design. Inthis case, such aspects as the cost of switching, connection matrixand the location of the concentrator and the switches are made. Inaddition, the project needs to consider network synthesis anddetermine the capacity of the components used (Penttinen,1999).
Inthe same line the project should also consider the performancecriteria in such aspects as Grade of Service (GOS). GOS is criticalin determining the network typology required and this can also helpin calculating the costs of transmission, routing size, componentsand plan. In addition, the project also needs to consider the networkrealization of the project in relation to its capacity to meet theexpected requirements, reliability and use the gathered informationin designing the actual circuit plan.
Recommendationsfor changes on the current network type
Patton-FullerCommunity Hospital (PFCH) Network Design Proposal implementersshould determine the capacity requirements of their networkinfrastructure in facilitating the implementation of the Tele-trafficGrade of Service (GOS) to be achieved. In order to achieve this, itis important to dimension the network infrastructure to allow fortraffic intensity when at peak. Dimensioning involves considering thenetwork infrastructure topology, GOS requirement and the trafficmatrix (Penttinen,1999).
Trafficengineering entails changing the path of the network infrastructureto reduce traffic congestion and improve capacity for more traffic.Traffic engineering enhances network infrastructure expansion whilelimiting high network load. In addition, new technologies could alsobe considered for the network types in order to solve the trafficproblem. These engineering technologies involve ATM, CSPF and MPLSwhich are the backbone of internet infrastructure design problemsolution (Farr,1988).
Networksecurity: Recommendations for improvements and benefits
Inorder to enhance the network security, Patton-FullerCommunity Hospital (PFCH) project needs to consider the survivabilityof the network this is critical in ensuring that there is maximumnetwork connectivity even during network failure. The mostsignificant thing to do is change the design requirements such asprotocol, topology and bandwidth allocation. Topology meansmaintaining a minimum of two connected networks to avoid failure froma single node. Changing protocol means rerouting the traffic duringnetwork transmission and dimensioning to safeguard against aspects asnetwork dynamics which may lead to problems in network equipment ordimensioning. Changing the bandwidth allocation requirements byadding more bandwidths helps to reduce traffic loss that occursduring failure conditions(Penttinen, 1999).
Themost significant thing that needs to be considered in enhancingsecurity of the network at Patton-Fuller Community Hospital (PFCH)project is the network capacity (Tele-traffic Grade of Service (GOS),topology, traffic matrix, bandwidth allocation and the routine plan.The success of network security depends on the network typologydesign, dimensioning, traffic engineering and the survivability ofthe network project. In the same line, dynamic routes could be usedthrough improved technologies such as CSPF in order to optimizeoffline tools. Furthermore, an end to end protection approach couldbe used to provide backup routes on the primary network routes.Patton-Fuller Community Hospital (PFCH) project could use dynamic andexplicit routes such as Juniper Networks and Cisco that facilitate alocalized capacity for MPLS network infrastructure(Farr, 1988).
