Abstract

Network based just-in-time compilation based on A Priori knowledge of a set of disparate clients is disclosed. One embodiment comprises using a web service to register a device and store a device profile containing the capabilities of the device, receiving a request from the device to subscribe to a content service, and to create a client runtime for the device for a requested service corresponding to the device capabilities. In this way, the embodiment may send the client runtime to the device to allow the device to communicate with the content service through the web service.

Claims17

Dependent claims

On a web service, a method of providing network based just-in-time compilation, the method comprising:

registering with the web service a device having a device profile containing device capabilities, the device being one of a plurality of devices having different device capabilities associated with a user identity;
receiving via a communication service of the web service a request from a requesting device among the plurality of devices to subscribe to a content service running on one or more of an external service provider and an external content provider, the content service providing a compilation of content corresponding to the user identity for selection from any device of the plurality of devices, wherein at least some content of the compilation of content is not supported by the requesting device;
upon receiving the request, obtaining device capabilities for the plurality of devices associated with the user identity;
receiving a selection of selected content from among the compilation of content provided by the content service;
selecting a selected device from among the plurality of devices appropriate for the selected content from the content service, based on the obtained device capabilities, the selected device not necessarily being the requesting device;
dynamically performing just-in-time creation of a client runtime specifically configured for the selected device based on the selected device capabilities;
and
performing just-in-time delivery of the client runtime via the communication service to the selected device to provide functionality for the selected device to communicate with the content service through the communication service of the web service to receive the selected content;
wherein registering a device having a device profile containing device capabilities involves registering a first device having a first device profile, the method further comprising:
registering a second device having a second device profile, the second device being another of the plurality of devices associated with the user identity;
and
creating a client runtime for the second device corresponding to a device capability contained in the second device profile.

9 more elements

A system for network based just-in-time (JIT) compilation, the system comprising:

a web service to register a device and store a device profile comprising device capabilities in memory, the device being one of a plurality of devices having different device capabilities associated with a user identity;
a protocol endpoint to receive a request from the device to subscribe to a content service, the content service providing a compilation of content to the user identity for selection from any device of the plurality of devices, wherein at least some content of the compilation of content is not supported by the requesting device;
a runtime service to receive a selection of selected content from among the compilation of content provided by the content service, select a selected device from a plurality of devices appropriate for the selected content, wherein the selected device selected from the plurality of devices appropriate for the selected content is based on obtained device capabilities, the selected device not necessarily being the requesting device, and dynamically perform just-in-time creation of a client runtime specifically configured for the selected device based on selected device capabilities contained in the device profile for the selected device, the client runtime configured to communicate with the content service when run on the selected device to receive the selected content from an external content service;
and
a communication service to perform just-in-time delivery of the client runtime to the selected device and to provide communication between the client runtime on the selected device and the content service upon receipt of the client runtime by the selected device;
wherein registering a device having a device profile containing device capabilities involves registering a first device having a first device profile, the method further comprising:
registering a second device having a second device profile, the second device being another of the plurality of devices associated with the user identity;
and
creating a client runtime for the second device corresponding to a device capability contained in the second device profile.

6 more elements

A non-transitory computer-readable medium comprising stored instructions executable by a computing device to provide network based just-in-time compilation, the instructions being executable to perform a method comprising:

registering with a web service a device having a device profile containing device capabilities the device being one of a plurality of devices having different device capabilities associated with a user identity;
receiving a request from the device to subscribe to a content service that provides a compilation of content to the user identity for selection from any device of the plurality of devices, wherein at least some content of the compilation of content is not supported by the requesting device;
upon receiving the request, obtaining the device capabilities from the device profile;
receiving a selection of selected content from among the compilation of content provided by the content service;
selecting a selected device from among the plurality of devices appropriate for the selected content from the content service, based on the obtained device capabilities, the selected device not necessarily being the requesting device;
dynamically performing just-in-time creation of a client runtime for the selected device based on the obtained device capabilities;
performing just-in-time delivery of the client runtime to the selected device, the client runtime configured to provide functionality for the selected device to communicate with and obtain the selected content from the content service through the web service;
after performing just-in-time delivery of the client runtime to the selected device, connecting the selected device with the content service;
and
providing via a pluggable request handler additional functionality to the selected device to communicate with the content service;
wherein registering a device having a device profile containing device capabilities involves registering a first device having a first device profile, further comprising stored instructions executable for:
registering a second device having a second device profile;
and
creating a client runtime for the second device corresponding to a device capability contained in the second device profile.
