    Study Notes

    Network Design and Management

    • A data network is a collection of devices and circuits for transferring data from one computer to another, enabling users to share resources at different locations.

    Goals of Network Design

    • Primary goal: meet the organization's communication needs.
    • Considerations: productivity, budget, suitability, reliability, scalability, and durability.

    Network Engineer/Administrator

    • Responsible for installing, maintaining, troubleshooting, optimizing, and expanding the network.
    • Use simulation to determine how to maximize network performance.

    Performance Management

    • Reduces probability of network congestion and inaccessibility, providing a consistent level of service to users.
    • Benefits: examines network trends, assists in allocating network resources, and reduces network congestion.

    Performance Terms

    • Availability
    • Bandwidth/Throughput
    • Propagation
    • Congestion
    • Latency
    • Threshold
    • Utilization

    Accounting Management

    • Process of gathering network statistics to help network engineers make decisions about resource allocation.
    • Involves: gathering data, setting usage quotas, and billing users.
    • Benefits: measures and reports accounting information, and allows for effective allocation of network resources.

    Data Collection, Modification, and Storing

    • Methods of storage: unstructured (e.g., ASCII files) and structured (e.g., DBMS).
    • Unstructured storage: easily read, accessed, and administered, but inefficient and slow to search.
    • Structured storage: efficient, enables data relationships, but requires query language and administrative overhead.

    Configuration Management

    • Benefits: automatically gathers and updates data on network devices, allows remote configuration, and provides central storage for configuration data.

    Security Management

    • Protects sensitive information on devices by controlling access points.

    Network Management Systems

    • Comprises: underlying architecture, software package, and set of applications.
    • Examples: HP Openview, SunConnect SunNet Manager, IBM Netview, Net-SNMP, and OpenNMS.
    • Platform functionality: user interface, network map, DBMS/MIB, query language, customizable menu, and event log.
    • Architectures: centralized, hierarchical, and distributed.

    Fault Management

    • Process of locating problems or faults on the data network.
    • Involves: detecting symptoms, isolating causes, and correcting problems.
    • Benefits: enhances network reliability, provides rapid fault detection, isolation, and recovery, and maintains the illusion of complete connectivity.
