[Freeswitch-users] Load Balancing

[Muhammad Shahzad]

There are many ways to achieve load balance and fail-over in VOIP world.
Each has its advantages and disadvantages, so the right solution really
depends on your needs rather then your wants (needs vs wants).

Please see attached research paper from Columbia University students, which
discusses the topic in detail.

Thank you.
