Abstract
Some embodiments relate to systems and methods for low latency monitoring. A communication system can include an application operating on the first device. The application is configured to append time stamps to a first packet received by the first device. The time stamps indicate a first time the first packet is received by the first device and a second time the first packet is sent by the first device.
Claims13
A server, comprising:
- one or more processors, coupled with memory, configured to execute a first application to:
- monitor end-to-end latency for a network comprising a plurality of devices configured to implement low-latency applications;
- receive latency information from at least one device of the plurality of devices, the latency information comprising (i) time stamps or time period data and (ii) an identification of a low-latency application type for a first packet being communicated via a path across the network;
- and
- transmit a second packet to adjust, based at least on the time stamps or the time period data providing an indication of latency with respect to transmission of the first packet and the identification of the low-latency application type, operations implemented at one or more nodes to control subsequent transmission of the first packet via the path across the network.

A method of providing low latency service, the method comprising:
- providing a first time stamp for a first packet provided to a first device, the first packet being for reception by a low-latency device or as being for use in a low-latency operation;
- providing a second packet comprising latency information to a server remote from the first device via a virtual communication link of a network, the latency information including the first time stamp, a second time stamp associated with transmission of the second packet, and an indication that the first packet corresponds to the low-latency device or is being used in the low-latency operation;
- and
- transmitting a third data packet to adjust, based at least on the first time stamp or the second time stamp providing an indication of latency with respect to transmission of the first packet, operations implemented at one or more nodes to control subsequent transmission of the first packet via a path across the network.
