Method and apparatus for determining a polling interval in a network management system
First Claim
1. A method for determining a time interval for periodically polling a network device on a network, the method comprisingdetermining a most restrictive link in a path to the network device from a second device, the restrictiveness of a link being dependent on the nature of the linkdetermining the time interval according to the nature of the most restrictive link, and polling at a rate specified by the time interval, wherein the step of determining a most restrictive link to the network device comprises:
- determining the nature of at least the links between routers on a path to the network device, and determining the most restrictive link according to the determined nature of the links.

Abstract
A method and apparatus for determining a time interval for periodically polling a device on a network 1 is described. The method determines the most restrictive link on the path to the network device, the level of restrictiveness of a link being dependent on the nature of the link, such as the link speed and link type. The time interval between polling is determined based on the nature of the most restrictive link. Thus, the time interval can be determined according to the type and speed of the links between the polling device, which in a preferred embodiment is a network management station, and the polled device on the network 1.

4. A method for determining a time interval for periodically polling a network device on a network, the method comprising
determining a most restrictive link in a path to the network device from a second device, the restrictiveness of a link being dependent on the nature of the link, determining the time interval according to the nature of the most restrictive link, and polling at a rate specified by the time interval, wherein the time interval is determined such that data traffic generated by polling is less than a predetermined proportion of the bandwidth of the most restrictive link.

6. An apparatus for determining a time interval for periodically polling a network device on a network,
the apparatus determining the most restrictive link in a path from a second device to the network device, the level of restrictiveness of a link being dependent on the nature of the link, the apparatus determining the time interval in accordance with the nature of the determined most restrictive link, and polling at a rate specified by the time interval, wherein the most restrictive link to the network device is determined by determining the nature of at least the links between routers on a path to the network device, and determining the most restrictive link according to the determined nature of the links.
