AI Technical Summary

Problems solved by technology

Combinations of propagation delays, serialization delays, queuing delays, and processing delays can often create complex and variable network latency scenarios
[0005] In hosts - measuring packet processing times - components of total network latency can involve complex setups
The complexity can increase if the host is placed away from the administrator (eg, as in the cloud)

Abstract

Techniques for measuring packet processing times of remotely connected host devices are generally described. According to some examples, link capacity may be measured to estimate packet processing time (PPT). The capacity of a link connected to a host can be measured by active probing where the host timestamps each probe packet after it is received. Accordingly, PPT information may be included in the packet reception process and the processing experienced by the packet as defined by the type of different computing applications, adding a timestamp to the packet is an example of a process involving processing time.

Description

technical field [0001] This disclosure relates to techniques for measuring packet processing times of end hosts by estimating end link capacity. Background technique [0002] Unless otherwise indicated herein, the materials described in this section are not prior art to the present application and are not admitted to be prior art by inclusion in this section. [0003] Network delay in a packet-switched network can be measured as one-way (the time from the source where the packet will be sent to the destination where the packet is received) or round-trip (the one-way delay from source to destination plus the time from destination back to source One-way delay) measurement. Although round-trip delay is more often used because it can be measured from a single point, it can obscure / hide the amount of time the destination system spends processing a packet. Some software platforms use ping operations, and ping operations can be used to measure round-trip delays. The Ping operati...
