Abstract
According to one aspect, a method includes monitoring traffic between a first network element and a second network element, and determining when no packets have been sent from the first network element towards the second network element within a predetermined amount of time. When it is determined that no packets have been sent from the first network element towards the second network element within the predetermined amount of time, the method includes sending at least one smart probe packet from the first network element to the second network element.
Claims21
A method comprising:
- monitoring traffic between a first network element and a second network element, the first network element and the second network element being on a network;
- determining when no packets have been sent from the first network element towards the second network element within a predetermined amount of time;
- and
- when it is determined that no packets have been sent from the first network element towards the second network element within the predetermined amount of time, sending at least a first smart probe packet from the first network element to the second network element at a first time, the first smart probe packet including the first time and information associated with when a last packet was obtained from the second network element.

A method comprising:
- monitoring traffic between a first network element and a second network element, the first network element and the second network element being on a network;
- determining when no packets have been sent from the first network element towards the second network element within a predetermined amount of time;
- when it is determined that no packets have been sent from the first network element towards the second network element within the predetermined amount of time, sending at least a first smart probe packet from the first network element to the second network element at a first time;
- and
- sending at least a second smart probe packet from the first network element towards the second network element after sending the first smart probe packet, wherein the first smart probe packet is a first on-demand probe packet and the second smart probe packet is at least a second on-demand probe packet, and wherein sending the first smart probe packet from the first network element to the second network element includes determining a burst size and an inter-packet gap length, wherein the second smart probe packet is sent at the inter-packet gap length after the first smart probe packet, and wherein the first smart probe packet and the second smart probe packet are included in a burst of on-demand probe packets of the burst size.
