Network Dictionary – Bandwidth Fairy

22nd August 2010 By 3 Comments

The Bandwidth Fairy is the preferred method for high volume data transfer of Project Managers, VMware admins, and Developers who assume that bandwidth is infinite and latency is zero.

Especially when the WAN circuit between two sites is less than two megs and already heavily congested and there is no budget for expensive WAN upgrades.

They believe that the Bandwidth Fairy will come along and wave his magic wand and all packets are magically transported from one site to another. The Bandwidth Fairy is, of course, the sister of the Tooth Fairy, except the network admin takes care of the packets.

DEV: we need to snapmirror 600gb/day from city A to city B.

ME: you’ll need min. 2xDS3, what’s your budget?

DEV: budget?

ME: *facepalm*. I guess you thought the Bandwidth Fairy was going to take care of it

    The Eight Fallacies of Distributed Computing

    by Peter Deutsch

    Essentially everyone, when they first build a distributed application, makes the following eight assumptions. All prove to be false in the long run and all cause big trouble and painful learning experiences.

    1. The network is reliable

    2. Latency is zero

    3. Bandwidth is infinite

    4. The network is secure

    5. Topology doesn’t change

    6. There is one administrator

    7. Transport cost is zero

    8. The network is homogeneous

    Not to forget the Latency Fairy.

    There is always the same latency for your packets no matter if it LAN, dial-up, or an VPN Tunnel from Europe to the south pole.
