F.4 Load Balancing With Windows Network Load
Balancing Service
F.4.1

Requirements

Load balancing between multiple instances of F-Secure Internet
Gatekeeper can be implemented with a Network Load Balancing service,
which is included in Windows Server 2003. The Network Load Balancing
service distributes incoming traffic among multiple servers, so they can
handle more traffic and provide higher availability and faster response
times.
In this chapter we set up network load balancing for 500 users in the local
network with 4 MB connection. You should use at least two servers with
the following hardware configuration:
Operating System:
Processor:
Memory:
Hard disk:
Network card:
Both servers do not have to be identical in the performance.
You can add new servers (up to 32 in one cluster) easily while the
system is running, without reconfiguring or restarting previously
configured servers.
Servers can be connected to the local area network, and they
need to be able to communicate with multicast or unicast.
Advanced Deployment Options
Windows Server 2003
Pentium III 1 GHz
1 GB
Ultra 160 SCSI Hard disk
100 Mbit/s Ethernet. Only one network card
per server is sufficient.
