Abstract
A network device receives probe packets communicated by a user equipment device. The network device communicates response packets back to the user equipment device, including timestamps, and/or other information. The user equipment device may be configured to test the performance of different portions of a wireless network (i.e., determine an available bandwidth measurement throughput (ABMT) of the wireless network) by accessing different network devices (or information associated with different network devices).
Claims15
A method for determining strain in a wireless network, the method comprising:
- retrieving a transmission time-stamp added to a probe packet at each of a plurality of protocol layers in an IP stack of a user equipment device;
- retrieving a reception time-stamp added to the probe packet at each of a plurality of protocol layers in an IP stack of a network device;
- comparing the transmission time-stamps from each of the plurality of protocol layers of the IP stack of the user equipment device with the reception time-stamps from each of the plurality of protocol layers of the IP stack of the network device;
- and
- determining a strain associated with each protocol layer based on the comparing.
A system for determining strain in a wireless network, the system comprising:
- a server comprising one or more processors configured to:
- retrieve a transmission time-stamp added to a probe packet at each of a plurality of protocol layers in an IP stack of a user equipment device;
- retrieve a reception time-stamp added to the probe packet at each of a plurality of protocol layers in an IP stack of a network device;
- compare the transmission time-stamps from each of the plurality of protocol layers of the IP stack of the user equipment device with the reception time-stamps from each of the plurality of protocol layers of the IP stack of the network device;
- and
- determine a strain associated with each protocol layer based on the comparison.
A non-transitory computer readable storage medium having one or more computer-readable instructions thereon which when executed by one or more processors cause the one or more processors to:
- retrieve a transmission time-stamp added to a probe packet at each of a plurality of protocol layers in an IP stack of a user equipment device;
- retrieve a reception time-stamp added to the probe packet at each of a plurality of protocol layers in an IP stack of a network device;
- compare the transmission time-stamps from each of the plurality of protocol layers of the IP stack of the user equipment device with the reception time-stamps from each of the plurality of protocol layers of the IP stack of the network device;
- and
- determine a strain associated with each protocol layer based on the comparison.
