16. A SYSTEMS METHODOLOGY
• Systems methodology means viewing the network
that you are architecting and designing, along with a
subset of its environment.
• The fundamental concepts of the systems methodology
is that network architectures and designs take into
account the services that each network will provide
and support.

18. A SYSTEMS DESCRIPTION
• A system is a set of components that work together to
support or provide connectivity, communications, and
services to users of the system.
• Generically speaking, components of the system include
users, applications, devices, and networks.

24. SERVICE DESCRIPTION
• Network services are defined as levels of performance and
function in the network. There are two perspectives:
• As services being offered by the network to the
rest of the system.
• As sets of requirements from the network that are
expected by the users, applications, or devices.

25. SERVICE DESCRIPTION

26. COURSECONTENTS
• Service Characteristics
• Service Levels
• System Components And Network Services
• Service Requests And Requirements

27. Service Characteristics
• Service characteristics are individual network performance and
functional parameters that are used to describe services.
• Characteristics of services that are requested from the network can
also be considered requirements for that network.

39. Service Offerings
• Service offerings are the network counterparts to users, application, and
device requests for service.
• Service offerings map to service requests and thus can also be
categorized as best effort, predictable, or guaranteed.

43. Performance Characteristics
• Capacity, is used as a label for the class of characteristics
that involves moving information from place to place, including
bandwidth, throughput, and so forth.
• Delay, is a label for the class of characteristics that includes
end-to-end delay, round-trip delay, and delay variation.
• RMA, is a label for the class of characteristics that includes
reliability, maintainability, and availability.

47. Network Supportability
Two major tasks must be accomplished to ensure
supportability:
1. Conformance to the network architecture and design must be
validated and nonconformance corrected or documented to
ensure that performance is adequate and that maintenance can
be performed.
2. Operations and maintenance personnel must understand and be
trained in the technologies that are being deployed.
