• Delay Queue High Water Mark. Controls the number of TCP or UDP connection requests in the delay
queue at which "virus-like" activity is considered to be occurring for each instance of the filter driver.
The default setting is 160 connection requests. The valid range is 1-Delay Queue Size.
• Delay Queue Low Water Mark. Controls the number of TCP or UDP connection requests in the delay
queue below which "virus-like" activity is considered to have stopped. The default setting is 100
connection requests. The valid range is 1-High Water Mark.
• Delay Period. Controls the rate at which TCP or UDP connection requests are removed from the
delay queue and passed down the protocol network stack. The default is 1 second. The valid range
is 1-10 seconds.
• Host Working Set Size. Controls the number of known machines to which TCP or UDP connections
are established without delay. When a new connection is made, the oldest member of the working
set is replaced with the new host. The default setting is 5 hosts. The valid range is 1-100.
• Address Lifetime (UDP). Number of timer intervals that an address will remain in the working set after
the last outbound UDP packet was sent to that address.
• Address Hint Lifetime (UDP). Number of timer intervals that an address is kept in the working set after
the last inbound UDP packet was received from that address.
• Max Slack (UDP).Maximum number of times new hosts are added to the working set per each timer
interval before adding to the delay queue.
