Abstract

Methods, systems, and devices for performing analytics on communications networks. For example, methods may include receiving, at an access point of a wireless network, a first transfer unit comprising first data destined for a first destination; receiving, at the access point, a second transfer unit comprising second data destined for a second destination; grouping, by the access point, the first and second transfer units into a group; and calculating, by the access point and based on the transfer units of the group, a response time associated with the first destination based on a time difference between the receiving of the first transfer unit and the receiving of the second transfer unit. The transfer units may comprise encrypted data.

Dependent claims

A method comprising:

receiving, at an access point of a wireless network, a first transfer unit of a plurality of upstream transfer units, the first transfer unit comprising first data destined for a first destination;
forwarding, by the access point, the first transfer unit that was received by the access point, to the first destination;
receiving, at the access point, a second transfer unit of a plurality of downstream transfer units, the second transfer unit comprising second data destined for a second destination;
forwarding, by the access point, the second transfer unit received by the access point to the second destination;
receiving, at the access point, a third transfer unit comprising third data destined for the second destination, wherein the second transfer unit and the third transfer unit are both responsive to the first transfer unit;
grouping, by the access point, the plurality of upstream transfer units and the plurality of downstream transfer units into a plurality of groups, a first group of the plurality of groups comprising a single upstream transfer unit comprising the first transfer unit and at least two of the plurality of downstream transfer units comprising the second transfer unit and the third transfer unit, wherein the grouping is based on respective statistical variances within each group of the plurality of groups and respective statistical variances between ones of the plurality of groups;
and
calculating, by the access point and based on the first, second, and third transfer units of the group that are received by the access point, a response time associated with the first destination based on a time difference between the receiving of the first transfer unit at the access point and the receiving a later one of the second transfer unit and the third transfer unit at the access point,
wherein the access point comprises at least one radio used to provide wireless network coverage in an area, and
wherein the first transfer unit comprises a request and the second transfer unit and the third transfer unit each comprises a response.

A method comprising:

receiving, by an access point of a wireless network, a first transfer unit of a plurality of upstream transfer units, the first transfer unit comprising encrypted first data destined for a first destination;
associating a first timestamp corresponding to the first transfer unit received at the access point to a first indexing identifier;
forwarding, by the access point, the first transfer unit that was received by the access point, to the first destination;
receiving, at the access point, a second transfer unit of a plurality of downstream transfer units, the second transfer unit comprising encrypted second data destined for a second destination;
forwarding, by the access point, the second transfer unit received by the access point to the second destination;
receiving, at the access point, a third transfer unit comprising third data destined for the second destination, wherein the second transfer unit and the third transfer unit are both responsive to the first transfer unit;
grouping, by the access point, the plurality of upstream transfer units and the plurality of downstream transfer units into a plurality of groups, a first group of the plurality of groups comprising a single upstream transfer unit comprising the first transfer unit and at least two of the plurality of downstream transfer units comprising the second transfer unit and the third transfer unit, wherein the grouping is based on respective statistical variances within each group of the plurality of groups and respective statistical variances between ones of the plurality of groups;
associating a second timestamp corresponding to the second transfer unit and the third transfer unit received at the access point to the first indexing identifier;
and
calculating, by the access point, a response time of a portion of a communication network based on a difference between the first timestamp and the second timestamp,
wherein the access point comprises at least one radio used to provide wireless network coverage in an area.

8 more elements

A method comprising:

receiving, by an access point of a wireless network, a plurality of upstream transfer units comprising encrypted first data destined for a first destination;
associating a first timestamp corresponding to an earliest received of the plurality of upstream transfer units received by the access point to a first indexing identifier;
forwarding, by the access point, the plurality of upstream transfer units that were received by the access point to the first destination;
receiving, at the access point, a plurality of downstream transfer units comprising encrypted second data destined for a second destination, wherein the plurality of downstream transfer units comprise a second transfer unit and a third transfer unit that are both associated with a first transfer unit of the plurality of upstream transfer units;
associating a second timestamp corresponding to a last received of the plurality of downstream transfer units received by the access point to the first indexing identifier;
forwarding, by the access point, the plurality of downstream transfer units that were received by the access point to the first destination;
grouping, by the access point, the plurality of upstream transfer units and the plurality of downstream transfer units into a plurality of groups, a first group of the plurality of groups comprising a single upstream transfer unit comprising the first transfer unit and at least two of the plurality of downstream transfer units comprising the second transfer unit and the third transfer unit, wherein the grouping is based on respective statistical variances within each group of the plurality of groups and respective statistical variances between ones of the plurality of groups;
and
calculating, by the access point, a response time of a portion of a communication network associated with the group based on a difference between the first timestamp and the second timestamp,
wherein the access point comprises at least one radio used to provide wireless network coverage in an area.
