This can lead to inconsistencies in the performance of Ethernet to fiber links. Internal communication between components in the client is managed through local methods calls and does not need particular support Create a module dedicated to access the time servers in the data layer of the Service Application reference architecture The service agents component from the reference architecture is adapted to abstract the access to the time servers. Set up your own groups of devices that make sense for your own organizational needs. Create CLI scripts that can be used for various device activities such as large scale configuration changes. This log can be viewed on-line or exported as a. These technologies have been developed in different programming languages?? Decisions regarding concurrent access have not been made yet.
Maintenance Registration Maintenance Inquiries. This will further facilitate the achievement of QA-2 and will play a critical role in the archievement of UC-2 and UC Download ppt “Chapter 7: Choose one or more elements of the system to refine This is a greenfield development effort, so in this case the element to refine is the entire FCAPS system In this case, refinement is performed fca;s decomposition.
Registration Forgot your password? A relational database server must be used CON It performs object-oriented to relational mapping and shields the rest of the application from persistence details Time server access module This module is responsible for communication with the time servers. The list events from the last 24 hours is displayed fcaaps 1 second UC-3 QA-6 Security A user performs a change in the system during normal operation.
To recognizing this type of failure, the network management system issues pro-active SNMP probes on a periodic basis. FCAPS model is developed. These can be filtered by various criteria such as type fccaps severity UC Specific devices can be managed directly using Telnet, SSH, http or https.
All tasks performed on PerleVIEW are stored in an audit trail log which can be viewed on-line or exported as a.
Chapter 7: Case Study FCAPS System (Part I).
Configuration Stuy Effective configuration management ensures that devices contain the right configuration based on policy. As information networks grow in size and businesses expect greater uptime and performance from their network backbone, there is an increased need to proactively monitor activity, notify when or before problems occur and provide alerting to administrators. This is generally done via pre-stored email or SMS addresses.
Monitor network status A user monitors the time servers in a hierarchical representation of the whole network. This may require an operator to respond to the alarm and acknowledge it or have this notification automatically sent out to individuals.
Administration Accounting Management For large enterprises, a number of groups of individuals with varying responsibilities are involved in the management of the network.
Managing Large-Scale Deployments
Businesses must retreat from ad-hoc management to some mechanism of configuration control to ensure network stability. Since the Rich Client is being programmed in Java, this supports execution under Windows, OSX, and Linux CON-3 Physically structure the application using 3-tier deployment pattern, and isolate the database by providing database access components in the data layer of the application server CON-4 Use of Java Web Start technology requires the client to be downloaded only the first time, and then when upgrades occur.
Some organizations with already established SNMP based stuxy may have the need to receive copies of the alerts received from the network. The company produces innovative products of digital and satellite communication that makes the secure, fast and efficient communication in any location. Manage time servers The administrator adds a time server to, or removes a time server from, the network.
4. Case Study: FCAPS System – Designing Software Architectures: A Practical Approach [Book]
Ad-Hoc Management Most networks begin small. Sketch views and record design decisions The deployment diagram stury Fig. Any process for configuration management needs to include a process whereby that environment can be audited against its baseline. Configure time server An administrator changes configuration parameters associated with a particular time server. My presentations Profile Feedback Log out.
Using Twitter As Twitter has become an important staple for mobile caee, some systems such as PerleVIEW enable administrators to set-up Twitter feeds for these notifications.
Sketch views and record design decisions Information about the relationships between some elements in the diagram that is worth recording is summarized in the following table: Functionality Usability Reliability Performance Supportability extensibility. Set up your own groups of devices that make sense for your own organizational needs. Communication with the time servers Sthdy No relvant decision made.
This server cannot be used for other purposes than hosting the database CON-4 The network connection to user workstations can have low bandwidth but is generally reliable CON-5 Performance data needs to be collected in intervals of no more than 5 minutes, as higher intervals result in time servers discarding data CON-6 Events from the last 30 days must be stored.
