datagram-size

UDP datagram size (bytes)—size of UDP datagrams used by the multicast protocol in bytes.

The allowed range is 512–8192. To avoid fragmentation, it is recommended that you set a value less than the MTU (Maximum Transmission Unit) of the network.

1400

assembly-timeout

File transmission time (ms.)—during the specified time a single update file is transmitted, after which Dr.Web Server starts sending the next file.

Any files that could not be transferred during the multicast update phase will be transferred during the standard TCP update session.

180000

updates-interval

Multicast update duration (ms.)—duration of the update process via the multicast protocol.

Any files that could not be transferred during the multicast update phase will be transferred during the standard TCP update session.

Dr.Web Server accumulates these requests and sends out any lost packets afterwards.

1000

silence-interval

“Silence” interval on the line (ms.)—whenever file transmission is over before the allotted time and no requests for retransmission of lost packages are received from Dr.Web Agents during the specified “wait” time interval, Dr.Web Server assumes that all Dr.Web Agents successfully received update files and initiates transfer of the next file.

When it is announced, a UDP datagram with file metadata is sent to the multicast group. Increasing the number of announcements can improve transmission reliability, but at the same time it may reduce the amount of data that can be transmitted in the time allotted for an update using the multicast protocol.

3
