Calculating bandwidth of repository replication
Repository replication consumes valuable bandwidth in all environments.
If you are only replicating DAT files, the bandwidth use will be approximately 70Mb of replication per
day. Agents don't use all the DAT files that are copied to the repository, but there are 35 incremental
DAT files that must be available to all agents in case they are behind on DATs. In order to determine if
you need a repository in a specific location, you must determine what is more costly in terms of
bandwidth usage; replicating 70mb worth of data to a repository, or telling the agents to go to the
next nearest repository which may not be geographically near the agents.
Calculating bandwidth for client pulls of updates
The bandwidth used to update a new product dramatically increases when updating a new product to
clients.
But you can calculate the bandwidth if you know the size of the patch or product being downloaded.
At a minimum, each of your clients must download 200 Kb per day for DAT files. The following
examples show how to calculate the bandwidth used for the client updates using this formula:
(Size of update file) x (Number of nodes) = Amount of data pulled per day
The following examples use this formula to calculate the amount of data pulled per day and describe if
creating a local repository would reduce the bandwidth.
Example 1 — A small office in India
The small office in India needs to download the 200 Kb per day for DAT files to its 200 nodes. Using
the formula:
(200 Kb) x (200 nodes) = 40 MB of data randomly pulled per day to India
