Developing supplemental performance requirements

Unit – II

Developing supplemental performance requirements

SUITABILITY(Legal Requirement): Measure of how well our network design can be

configured, monitored and adjusted by the customers.

SUPPORTABILITY(operational requirement): Measure of how well the customer can keep the

system performing, as designed over the entire life of the system.

CONFIDENCE(Assurance): Measure of the ability of the network to deliver

data without error or loss at required throughput.

OPERATIONAL SUITABILITY FACTORS

Network management permits the operators(service provider) to adjust and reconfigure it when they need.

System monitoring is essential to adjusting system performance by its operators(user).

Operators(service provider) are more essential than any technology to successful communication over a network.

Design engineer develop their opinion about their skill level and ability to understand new technology and adopt new procedures and tools.

Operating System requirement must be collected from interviews with operators(service provider) and owners.

TYPES OF SERVICE PROVIDER Types of service providers Application service provider (ASP) Network service provider (NSP) Internet service provider (ISP) Storage service provider (SSP) Telecommunications service provider (TSP)

Questions during requirement analysis process

How the operators(service provider) going to monitor performance to ensure that they detect failures or faults.

How does the end user(customer) interact with the system and the operators(service provider) including reporting problems.

End user is a person that uses a particular product.

who uses a product after it has been fully developed and marketed.

SUPPORTABILITY FACTORS It is the ability to maintain the high level of performance

achieved on the day of delivery throughout life of the network design.

Customer will recognize the poor quality of a design and implementation only when it is frequently out of service.

Five major factors: RMA characteristics(Reliability, Maintainability,

Availability) Workforce(high quality employment resources) including

training and staffing levels. System procedures(software installation) and technical

documentation. Tools both standard and special. Spare and repair parts.

Workforce(Activity) Definition:

1. The workers employed in a specific project or activity. 2. All the people working or available to work. 3. the workers engaged in a specific activity. 4. set of processes that an institution uses to optimize the

productivity of its employees . Re-taining(Maintaining) the existing workforce /

keeping the budget the same. Workforce Re-taining / replacement may be required

in the implementation. Survey the existing workforce skills, depth and formal

training, document, features and use them as the baseline for the new network maintenance workforce.

Procedures and documentation It describes both periodic preventive maintenance

actions and scheduled performance. Maintenance procedures must support both

component level and system level maintenance.

maintenance actions such as part of the testing, Deployment(separation) mapping tool / several interrelated activities with

possible transitions. Integration(implement or act or process of making

entire) of the new network.

tool tools is an importance of network architecture. ‘Test equipment’ New tools should be develop for service, to

ensure that they work properly with the planned network configuration.

perform tasks: Special test equipment Monitoring It improve

response time. system performance issues including failures and

faults.

Repair and spare parts it shall be stored in the network operations

facility and cannot exceed, in volume(amount of space) / the space allocated.

Initial spare and repair parts shall not exceed 15% of system developing/quality costs.

Support concept(helpline) It helps to showing the customer constraints. Helps to identify alternative approaches. At the local level operators(LRU) can perform a set

of minimal maintenance actions(failed component)

They can monitor for component failure, and it is used to isolate/identify the problem.

They can handle immediate actions for system faults and some supplemental actions such as Rerouting circuits Replacing certain line replaceable units. Shipping the equipment back to a maintenance location.

NETWORK DESIGN

Network planning and design is an Iterative process Encompassing topological design, Network-synthesis(designing signal processing

filters), Network-realization(concepts/services), Telecommunications network Service meets

the needs of the subscriber and operator.
