Disclosed are systems, methods, devices and non-transitory, computer-readable storage media for edge caching shared devices. In some implementations, a method comprises: receiving, by an edge cache server on a local area network (LAN) from a client device, a locate server request; determining, by the edge cache server, that the edge cache server has established server affinity with a user of the client device; sending, by the edge cache server to the client device, affinity data corresponding to the user; receiving, by the edge cache server from the client device, a request to transfer user data corresponding to the user; determining, by the edge cache server, that a new version of the user data is available; downloading, by the edge cache server, the new version of the user data; and sending, by the edge cache server to the client device, the new version of the user data.

Edge caching shared devices

Systems, methods, devices and non-transitory, computer-readable mediums are disclosed for device-to-device caching. In some implementations, a method includes: registering, by an electronic device, a cache service on a local area network (LAN), the LAN including other registered electronic devices; generating, by the electronic device, a content map for cached content, the content map generated from descriptors of the cached content and including data indicating that the cached content described by the content descriptors is possibly cached or is definitely not cached by the electronic device; advertising, by the electronic device, the registered cache service and the content map; receiving, by the electronic device, a request for content from a requesting electronic device registered on the LAN; determining, by the electronic device, that the requested content is cached; and sending, by the electronic device, the requested content to the requesting electronic device.

Device-to-device caching

Disclosed are systems, methods, devices and non-transitory, computer-readable storage mediums for edge caching shared devices. In some implementations, a method comprises: receiving, by a client device on a local area network (LAN), a request for data transfer from a user of the client device; determining, by the client device, if one of a plurality of edge cache servers on the LAN has established server affinity with the user; if an edge cache server has established server affinity with the user, initiating, by the client device, data transfer between the client device and the edge cache server; and if no edge cache server on the LAN has established server affinity with the user, establishing, by the client device, server affinity between the user and one of the plurality of edge cache servers.

In the described embodiments, local caching servers (LCSs) are configured to cache content so that the content can be acquired by client electronic devices that are located on local area networks (LANs) with the LCSs. In some embodiments, to enable the acquisition of the cached content, a client electronic device sends, to a registration server, a request for identifiers for LCSs that are located on a LAN with the client electronic device. The request includes one or more 'listen ranges,' each of which includes an indication of client electronic devices for which a corresponding LCS is to provide content. The registration server uses the listen ranges to select one or more LCSs, and returns identifiers for the one or more LCSs to the client electronic device. Using the one or more identifiers, the client electronic device acquires the content from an LCS via the LAN.

Using listen ranges to deliver content to electronic devices from local caching servers

An email server receives an email sent to an email account and including one or more attachments. The one or more attachments are extracted from the email into one or more temporary storage elements. Content from the temporary storage elements is indexed. The indexed content is stored along with an identifier of the email in an index corresponding to the email account. The one or more temporary storage elements is disposed of after the indexing.
