Synchronizing a client with the Administration Server

This scenario describes the state of the administration system when intensive data synchronization occurs between a client device and the Administration Server. Client devices connect to the Administration Server with the interval defined by the administrator. The Administration Server compares the status of data on a client device with that on the Server, records information in the database about the last client device connection, and synchronizes data.

This section contains information about traffic values for basic administration scenarios when connecting a client to the Administration Server (see table below). The data in the table may vary slightly depending upon the current version of the anti-virus database.

Traffic

Scenario	Traffic from client devices to Administration Server, KB	Traffic from Administration Server to client devices, KB	Total traffic (for a single client device), KB
Initial synchronization prior to updating databases on a client device	699.44	568.42	1267.86
Initial synchronization after updating databases on a client device	735.8	4474.88	5210.68
Synchronization with no changes on a client device and the Administration Server	11.99	6.73	18.72
Synchronization after changing the value of a setting in a group policy	9.79	11.39	21.18
Synchronization after changing the value of a setting in a group task	11.27	11.72	22.99
Forced synchronization with no changes on a client device	77.59	99.45	177.04

Overall traffic volume varies considerably depending on whether IP multicasting is used within administration groups. If IP multicasting is used, the total traffic volume decreases approximately by N times for the group, where N stands for the total number of devices included in the administration group.

The volume of traffic at initial synchronization before and after an update of the databases is specified for the following cases:

Installing Network Agent and a security application on a client device
Moving a client device to an administration group
Applying a policy and tasks that have been created for the group by default, to a client device

The table specifies traffic rates in case of changes to one of the protection settings that are included in the Kaspersky Endpoint Security policy settings. Data for other policy settings may differ from data displayed in the table.
