Site survey – includes information like:
- numbers of users and types of equipment
- projected growth
- current Internet connectivity
- application requirements
- existing network infrastructure and physical layout
- new services required
- security and privacy considerations
- reliability and uptime expectations
- budget constrains
Physical topology – the actual phyical location of cables, computers and others peripherals
Logical topology - documents the path the data takes through the network and where network functions, like routing
- includes the naming and Layer 3 addresing of end stations, router gateways and other network devices
Topology arrangements:
Inentory sheet – includes :
1.) Requirements gathering
– network requirements
– is done by the design team at the ISP which creates an Analysis Report
2.) Selection and design
– devices and cables are selected
– prototypes are created and tested; prototype is a good indicator of howthe network will operate
– multiple design options are created
3.) Implentation
– installation of the network
4.) Operation
– the network is brought into service= production environment
5.) Review and evaluation
– compare the user experience with the goals in the documentation
– compare the projected design and costs with the actual deplyment
– monitor the operation and record changes
MDF (Main Distribution Facility) is a telecommunications room or wiring closet in a small, single floor network. Contains many of the network devices and is the place where all the cables concentrates to a single access point. Also , containd the POP.
IDF (Intermediate Distribution system) – additional wiring closets, typically smaller than MDF.
Twisted Pair Cables:
a.) Straight-through – connects similar devices,such as a switch and a PC or a switch and a router.
b.) Crossover – connects similar devices, 2 switches or 2 computers.
c.) Console – connects a computer to the console port of a router or switch to do initial configuration
Serial cable – use to connect the router to an Internet connection
The floor plan is the first step to be done when designing. Allows the technician to identify possible wiring closet locations, cables runs and which electrical area to avoid.
Patch cable is a short cable from computer to the wall plate in the user work area.
Horizontal cable is a cable from the wall plate to the IDF in the distribution area.
Vertical cable is a cable from the IDF to the MDF in the backbone area of the bssiness.
Backbone cable is the network part that handles the major traffic.
Cable management system – trays and straps used to guide and protect cable runs.
Cable labeling system – labelling system or scheme to identify cables.
Two options for obtaining new equipment:
a.) Managed service – the equipment is obtain from the ISP
b.) Inhouse – the customer purchases the equipment
Factors when selecting a switch:
Availability – five 9s – available 99.999% of the time
Fault tolerence systems:
- numbers of users and types of equipment
- projected growth
- current Internet connectivity
- application requirements
- existing network infrastructure and physical layout
- new services required
- security and privacy considerations
- reliability and uptime expectations
- budget constrains
Physical topology – the actual phyical location of cables, computers and others peripherals
Logical topology - documents the path the data takes through the network and where network functions, like routing
- includes the naming and Layer 3 addresing of end stations, router gateways and other network devices
Topology arrangements:
- Star
- Extended star
- Partial mesh
- Full mesh
Inentory sheet – includes :
- device name
- date of purchase
- warranty information
- location
- brand and model
- operating system
- logical addresing information
- gateway
- method of connectivity
- virus checker
- security information

Factors when selecting a switch:
- speed and types of ports and interfaces involved
- expandability (modular devices)
- manageability
- cost
- type of connectivity required (LAN or WAN)
- cost
- features available: – security
- quality of service
- NAT
- DHCP
- Virtual Private Network(VPN)
- VoIP
- Intrusion detection
Availability – five 9s – available 99.999% of the time
