Deployment guide
For the Elements of the access network not covered in the Google document “
”, the table below walks through a deployment guide for small,
medium and large networks.
Access area
Small network
Serving < 500
concurrent users
- Total users up to 2000
- 1 or 2 buildings
- < 1000 sqMtrs
Medium network
Serving 500 - 2000
concurrent users
- Total users 2K -> 10K
- 3 to 15 buildings
- Single campus
large network
Serving 2000 - 5000
concurrent users
- Total users 10K -> 50K
- 16 to 100 buildings
- Multiple campuses
Bandwidth

redundancy)
64kbps,

Lowest = 32 Mbps
Mid = 64 Mbps
High = 256 Mbps
Lowest = 32 Mbps
Mid = 256 Mbps
High = 1 Gbps
Lowest = 320 Mbps
Mid = 640 Mbps
High = 2.5 Gbps
Firewalls
If you can live without granular
L7 firewall controls you can
use your routers ACL for
simple allow / deny rules.
Else buy a small sized firewall
sized appropriately ( see
sizing elements on the large
network box).
If you can live without granular
L7 firewall controls you can
use your routers ACL for
simple allow / deny rules,
Else buy a Mid sized firewall
sized appropriately ( see
sizing elements on the large
network box).
Typically you will need a large
sized firewall, sized for
- Network capacity
- Connections per second
- Concurrent connections
- Packets per second
- VPN throughput (if required)
- IPS throughput (if required)
- various other capacity
metrics
LAN : Routers
Pick a router that has capacity
(CPU, Memory, Backplane…)
to:
- route your link speed
- Has the variety of interfaces
you will use now and the near
future (T3/E3, GbE Copper or
Fiber (SFP’s)

LAN : VLANS
In order to reduce the size
of your broadcast domains
consider using VLAN (
VLAN tagging can also be
implemented on wireless
traffic as long as the AP’s and
wireless controllers support it.
Also it is recommend that each
SSID has its own VLAN.
