 Part I - Design goals
      The design is mainly based on the following four considerations:
      1. Functionality
         The design will provide Royal Palm school a reliable Local Area Network
         (LAN) as well as Wide Area Network (WAN) link for data communication with
         other school sites in the Washington School District and the Internet
         connectivity.
      2. Scalability
         The design will allow the network to grow without any major changes in the
         overall design.
      3. Adaptability
         The layered design will allow the network to adapt to and implement the future
         network technology.
      4. Manageability
         Network monitoring and management will be taken into account for ensuring the
         day to day network stability.

 Part III – LAN design: VLAN
      VLAN will be used to create two segments in the LAN.
      One Route Switching Module (RSM) in Catalyst 5500 and a
       2620 router will be used for routing between two VLANs, the
       2620 one is for backup (fail-over) purpose.
      Internal security will be done by using Access Control Lists
       (ACLs) in the RSM and 2620 router.

 Part III – LAN design: Bandwidth
      Each switch port provides 100Mbps bandwidth
      Each backbone switching port connected by multimode fiber
       optic provides 1Gbps bandwidth
      Student PCs will connect to the 8-port hubs that attached to a
       switch port, each getting 100Mbps / 8 = 12.5Mbps
      The teachers, administrations and servers will be connected to
       the switch port directly, each having 100Mbps

 Part III – LAN design: Addressing and Routing
      Addressing
          The IP address follows the District Office standard
          There are two subnets in the LAN:
             172.18.8.0/24 for administration, teachers, servers and network devices:
                172.18.8.1 ~ 172.18.8.99    Static IP for administration and teachers
                172.18.8.100 ~ 172.18.8.149 For servers
                172.18.8.150 ~ 172.18.8.199 For network devices and printers

             172.18.9.0/24 for students PC DHCP
                The Route Switch Modules will act as DHCP server

             172.18.10.0/24 and 172.18.11.0/24 are reserved for future usage


      Routing
          Static routing inside the LAN
          Dynamic routing for WAN, IGRP will be the routing protocol
          NAT will not be used inside the LAN and WAN as the IP address are
           compatible with other sites.

       Royal Palm Network Design Proposal

 Part III – LAN design: Security
      The VLAN provides good security for the internal LAN
          It isolates the broadcast in each LAN segment
          ACLs will be applied to control the access:
             Administration and teachers  students
             All  internet
          Firewall is suggested to outside the WAN link for protecting the internal
           LAN.

 Part V – Conclusion
      The Catalyst 5500 switch using modular-design provides high
       performance, flexibility and manageability.

      Scalability
           Additional switching module can be added by simply plug in when needed


      Adaptability
           The modular-design also provides the flexibility for implementing future
            network technology by adding new modules.


      Drawback
           The only disadvantage will be the cost, however, if you look at the
            performance and stability, you will find it cost-effective.
