2.8.1 Timers
It is recommended that an update server use a timer to trigger periodic synchronization with its USS. The frequency of the timer is implementation-specific. The synchronization time and frequency will be configurable so that the WSUS administrator can set a schedule based on the administrative schedule, requirements on the timeliness of the updates, and the WSUS topology that is deployed in an environment, as specified in [MS-WSUSSS] section 3.2.3. The periodic synchronization of the update server with its USS affect update clients that are synchronizing with the update server due to the relationships between the protocols, as described in section 2.1.2.2.
Similarly, it is recommended that an update client use a timer to trigger periodic reporting to its update server. The frequency of the timer is implementation-specific. The periodic reporting of the update client to its update server affects the update server's USS due to the relationship between the protocols, as described in section 2.1.2.2.<1>
