Corporate Network Planning

overview
Overview
  • Why we need to manage networks
  • Requirements capture and specification
  • Documenting the network configuration.
why do we need to manage a network
Why Do We Need to Manage a Network?
  • The network is an important asset to the organisation
    • The larger the organisation the more dependent they are on the telecommunications network
    • This telecommunications network includes
      • PABX / telephone infrastructure
      • mainframe, server, routers, bridges, hubs, hosts, terminals, modems
      • and other telecommunications devices
why do we need to manage a network1
Why Do We Need to Manage a Network?
  • All these need to be managed within the organisation as a important part of the organisations infrastructure
why do we need to manage a network2
Why Do We Need to Manage a Network?
  • Personnel who maintain and enhance this telecommunication network need to be
    • Well trained
    • Willing to adapt to changes in the objectives of the organisation as quickly as they can
    • Staff turn over can be a major network management problem that needs to be monitored
design
Design
  • Many networks are composed of ad hoc network design
  • Network components are often added by a small group within the organisation on a needs basis
design1
Design
  • This then becomes a example of decentralised network configuration
    • Making network management more difficult
    • Especially if individual sections chose different and incompatible network components (often called proprietary solutions)
    • Less of a problem if a standard has been used by the vendors who provided the network component
design2
Design
  • As the organisation grows, so will the network
    • Changes need to be made and documented
    • Future growth projections need to be made
  • The network is a capital expense
    • Ad hoc network planning should be avoided
    • The needs of individual sections of the organisation should be given appropriate attention.

configuration management
Configuration Management
  • Set of middle and long range activities for controlling
    • Physical, logical and electrical inventories
    • Maintaining vendor files and trouble tickets
  • Support for provisioning and order processing
  • Managing changes
  • etc…
sectionalisation of networks
Sectionalisation of Networks
  • As networks grow larger there is a trend to divide the network into smaller segments
  • This introduces several problems for managing the network
sectionalisation of networks1
Sectionalisation of Networks
  • Separate voice and data management
    • Inventory control of shared resources is made more difficult
  • Geographical spread of organisations
    • Where do we keep the inventories
  • Lack of integrated addressing and naming
    • Too many views of the network
    • Physical, electrical and logical configurations
processes and procedures
Processes and Procedures
  • Configuration management can be considered the central process of network management
    • All other areas are supported by configuration details

inventory management
Inventory Management
  • An automated inventory that provides a record of currently installed equipment and spares
    • Equipment (modems, switches, servers, workstations, phones)
    • Facilities (tie lines, trunks)
    • Circuits (individual, groups, multipoint)
    • Networks
    • Services offered
    • Customers
    • Provider, vendor, location and contact
  • All of these need to be documented
equipment inventory
Equipment Inventory
  • This needs to be updated to keep track of
    • Installed equipment and circuits
    • Additions and deletions
  • Can be used to
    • Generate reports of all equipment of a given model
    • Find the location of a unit with a certain serial number
    • Generate cost reports based on circuit types
    • Etc
network diagrams
Network Diagrams
  • The topology of the network at any given time can be extracted from the equipment inventory
  • This shows
    • Network locations
    • Controllers
    • Computers
    • Circuits connecting them
network diagrams1
Network Diagrams
  • The configuration inventories can also provide
    • Circuit listings
      • Devices attached to each circuit
    • Wiring diagrams
vendor control
Vendor Control
  • Vendor information is required to allow the quick retrieval of
    • All equipment of a given vendor
    • Performance statistics for certain equipment from a vendor
    • Contract expiration schedule
    • Invoice verification
    • Maintenance requirements
    • Service statistics
      • Number of outages, Response time for repair, Repair time distribution, MTBF, MTTR, MTOR
vendor control1
Vendor Control
  • Vendor information helps to
    • Prepare for vendor negotiations
    • Reduce costs by removing overpayments
    • Reduce clerical costs
    • Improve contract control
    • Facilitate budget preparations
    • Make equipment and vendor selection objective
benefits of configuration management
Benefits of Configuration Management
  • Reduced redundancy
  • Synchronised change management
  • Unique names and addresses
  • More efficient troubleshooting
  • Easier capacity and contingency planning
