Abstract
A polling apparatus comprises message issuing circuitry configured to issue at least one polling message over a network to a polled device. Polling filtering circuitry is responsive to a polling trigger requesting that the message issuing circuitry issues a given polling message to determine whether an active domain name system (DNS) server belongs to a set of one or more polling permitted DNS servers. In response to determining that the active DNS server does not belong to the set of polling permitted DNS servers, the polling filtering circuitry is configured to prohibit the message issuing circuitry from issuing the given polling message.
Claims18
A polling apparatus, comprising:
- message issuing circuitry configured to issue at least one polling message over a network to a polled device, and
- polling filtering circuitry responsive to a polling trigger requesting that the message issuing circuitry issues a given polling message, to:
- determine whether an active domain name system (DNS) server belongs to a set of one or more polling permitted DNS servers;
- and
- in response to determining that the active DNS server does not belong to the set of polling permitted DNS servers, prohibit the message issuing circuitry from issuing the given polling message.
A method for controlling issuing of polling messages, comprising:
- responsive to a polling trigger requesting issuing of a given polling message over a network to a polled device:
- determining whether an active domain name system (DNS) server belongs to a set of one or more polling permitted DNS servers;
- and
- in response to determining that the active DNS server does not belong to the set of polling permitted DNS servers, prohibiting issuing of the given polling message.
A network control apparatus, comprising:
- polling status determination circuitry configured to determine a desired polling status for a given polling apparatus, the desired polling status indicating whether the given polling apparatus is permitted to issue at least one polling message over a network;
- and
- polling control circuitry configured to issue one or more control messages to request that the given polling apparatus updates an indication of an active domain name system (DNS) server in dependence on the desired polling status.
A method for controlling a network, comprising:
- determining a desired polling status for a given polling apparatus, the desired polling status indicating whether the given polling apparatus is permitted to issue at least one polling message over the network;
- and
- issuing a control message to request that the given polling apparatus updates an indication of an active domain name system (DNS) server in dependence on the desired polling status.
