Managing Network Session 4 : Network Management Activities
Transcript of Managing Network Session 4 : Network Management Activities
By end of this session we will be able to explain different network management functions
Some common network management activities are:
This is the phase where the network will be designed according to the plan and the network will be implemented and tested according to the design. This the network management activity which needs lots of expertise and testing after implementation.
Designing and installing a network
Network management has its life cycle.....
Gathering information from end user, agree and priorities the requirements, assess requirements, examine constraints, capacity planning, design network solution, implement network solution, performance review.
Gather Information Find out which services (e.g. email, internet access, online sales etc.) are required by end users.
Agree and priorities the requirements:
Define which requested services and features are critical (‘must haves’), which are desirable (‘would be nice’) and which are worth noting but are either luxuries or possible future developments
Design network solution: Need to plan a solution that covers:
• Servers and workstations, NOS, tools and application selection, Selection and placement of network devices
• User groupings and their needs, Network services required, Capacity needs identified
• Cabling infrastructure (topology), External links for internet connection
• Security, Impact on organisation, Contingency plans (what to do when things go wrong)• Schedule of deployment (e.g. Gantt chart)
All choices and reasoning should be fully justified and documented
Good planning accounts for capacity load and therefore maximises resources and provides a good, reliable service to the organisation’s internal (employees) and external customers.
The anticipated and required capacity of the network has a big impact on the network design and implementation stages.
User needs and populations (i.e. maximum potential simultaneous logins)
• Application behaviour (its generated network traffic)• Identifying baseline network requirements• Project heaviest network loading (identify potential bottlenecks)
Networks should provide:
the services required by their end users;
Improve communications within an organisation;
Improve sharing of resources within an organisation;
Provide these services with acceptable response times; be cost effective and within a planned and agreed budget;
work reliably and flexibly; be expandable without requiring major changes; be easy to manage on a day-to-day basis;
have good support documentation.
Obvious limiting factors such as time, money etc. However, there may be other physical constraints such as cable installation (if for example the premises are old or of historic significance it may be more appropriate to envisage wireless networking), issues for placement of new servers or equipment.
Planing, Designing & Implementing the network

I tried to make sure that the cited information is correct, but errors may occur.
Essay by history teacher
History of the World
Timeline of the future in forecasts
Networks represent an expensive but necessary investment for modern organisations; as such it is very important that planning is performed in a responsible and thorough manner. Any mistakes made in the planning and design phases could have costly repercussions later. This phase links neatly to the design phase.

Account Management, Performance Management, user response time management, network security, data logging, reporting etc
It is necessary to assess all the requirements which have been identified so that requirements (what is wanted) can be converted into deliverables (what will be paid for and completed). Things that will affect the decision:
• Commissioning costs (getting the project started); Project management fees;
• Hardware costs (including upgrades, new purchases and safe disposal of old equipment);
• Software costs (including NOS); Consultancy costs; Ongoing support and maintenance costs; Training costs.
By working in a group please identify network management activities
Planning Designing and Implementation of the Network
User Account Management
Network Performance Management
User response time management
Network security management
Implement network solution
Full implementation will typically include:
• Cable infrastructure installation (this may be performed by an external agency for speed purposes)
• Networking device installation and configuration
• Server installation and configuration (e.g. mail server, intranet etc.)
• Domain and user account configuration
• Installation and configuration of required network services
• Creation of log-in scripts
• Quality of Service (QoS) configuration for important data/services
Examining and reviewing network performance is critical. Performance variables to look at include:
• Network data throughput
• Network collisions and congestion
• User response times (log-in, file transfers, email requests etc.)
• Line utilisation
• User satisfactions (through focus groups, questionnaires, online surveys or feedback etc.)
Network Management has its own lifecycle, which includes:
Gathering information from end user, agree and priorities the requirements, assess requirements, examine constraints, capacity planning, design network solution, implement network solution, performance review
