    Switched topology

    Advantages/Disadvantages of a Switched topology

    • Advantage:
      • Can improve LAN performance:
        • increase the aggregate bandwidth available throughout the network
        • reducing the number of devices forced to share each segment of bandwidth
    • Disadvantage:
      • Large switched implementations do not isolate broadcasts

    Daisy chains

    • Developed by serially interconnecting all the hubs of a network
    • This simple approach uses ports on existing hubs for interconnecting the hubs
    • Daisy chains are easily built and don’t require any special administrative skills
    • Daisy chains were, historically, the interconnection method of choice for emerging, first-generation LANs

    Daisy chains

    Disadvantage of Daisy chain

    • Increases the number of connections, and therefore the number of devices, on a LAN. Too many devices competing for the same amount of bandwidth can create collisions and quickly incapacitate a LAN

    Hierarchies

    • Hierarchical topologies consist of more than one layer of hubs. Each layer serves a different network function
    • The bottom tier is reserved for user station and server connectivity. Higher-level tiers provide aggregation of the user-level tier
    • A hierarchical arrangement is best suited for medium-to-large-sized LANs that must be concerned with scalability of the network and with traffic aggregation

    Hierarchical rings

    • Ring networks can be scaled up by interconnecting multiple rings in a hierarchical fashion
    • User station and server connectivity can be provided by as many limited size rings as are necessary to provide the required level of performance
    • A second-tier ring, either Token Ring or FDDI, can be used to interconnect all the user level rings and to provide aggregated access to the Wide Area Network (WAN)
