Abstract

An update service of a provider network transmits an update to an edge device by opportunistically selecting one communication channel (or transmission bandwidth) over another (e.g., based on analysis of performance metrics associated with the channel) to transmit different portions of the update to the edge device. For example, the update service may choose the channel with highest available bandwidth or the channel with the lowest failure rates. The update service may receive indications from the edge device that transmission of different update portions was successful. In some cases, the edge device itself may instead perform the selection of one communication channel over another (e.g., based on analysis of channel metrics) to receive different portions of the update at the edge device. The edge device may transmit indications that the edge device successfully received different portions of the update.

Dependent claims

A system, comprising:

one or more computing devices of a provider network comprising respective processors and memory to implement an update service for one or more clients to:
receive an indication of one or more edge devices of one or more remote networks that are to receive an update;
and
for individual ones of the one or more edge devices:
transmit one or more portions of the update to the edge device using one of a plurality of communication channels that the edge device is configured to use, wherein the one or more portions are transmitted using a transmission bandwidth for the communication channel;
receive one or more indications from the edge device that the transmission of at least one of the one or more portions of the update using the communication channel was successful;
receive one or more metrics associated with respective communication channels of the plurality of communication channels;
analyze the one or more metrics associated with the respective communication channels;
based on the analysis of the one or more metrics associated with different channels of the respective communication channels that the edge device is configured to use:
select another of the communication channels to transmit one or more other portions of the same update;
select a time to transmit the one or more other portions of the same update using the other selected communication channel;
and
transmit the one or more other portions of the same update to the edge device using the other selected communication channel in accordance with the selection of the time to transmit, wherein the communication channel used to transmit the one or more portions of the update is different than the other selected communication channel used to transmit the one or more other portions of the same update;
and
receive one or more indications from the edge device that the transmission of at least one of the one or more other portions of the same update to the edge device was successful.

12 more elements

A method, comprising:

performing, by one or more computing devices of a provider network:
for individual ones of the one or more edge devices of one or more remote networks:
receiving one or more metrics associated with respective communication channels of a plurality of communication channels that the edge device is configured to use;
analyzing the one or more metrics associated with the respective communication channels;
and
based on analyzing the one or more metrics associated with different channels of the respective communication channels that the edge device is configured to use:
selecting one of the communication channels;
selecting a time to transmit one or more portions of an update using the selected communication channel;
and
transmitting the one or more portions of the update to the edge device using the selected communication channel in accordance with the selection of the time to transmit, wherein at least another portion of the same update is transmitted to the edge device using a different channel than the selected communication channel.

7 more elements

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors:

receive from a provider network one or more portions of an update at an edge device using one of a plurality of communication channels that the edge device is configured to use;
transmit to the provider network one or more indications that transmission of at least one of the one or more portions of the update was successful;
collect one or more metrics associated with respective communication channels of the plurality of communication channels;
analyze, by the edge device, the one or more metrics associated with different channels of the respective communication channels;
based on the analysis, by the edge device, of the one or more metrics associated with different channels of the respective communication channels that the edge device is configured to use:
select, by the edge device, another of the communication channels;
and
receive, by the edge device, one or more other portions of the same update at the edge device using the other selected communication channel, wherein the communication channel used to receive the one or more portions of the update is different than the other selected communication channel used to receive the one or more other portions of the same update;
and
transmit to the provider network one or more indications that transmission of at least one of the one or more other portions of the same update was successful.
