Techniques for efficient roaming of clients between access points (APs) of a wireless data communications network are described. A first AP receives a request for a first client device to join the network. The request specifies at least a unique identifier for the first client device. An identifier for a second AP is identified by processing the unique identifier using a predefined hash function. The second AP is one of at least two APs configured to each redundantly store network state information relating to the first client device. A network address of the second AP is determined. A first request to is transmitted to the network address, for network state information including a pairwise master key (PMK) and profile information. The PMK and the profile information are received. The first client device is authenticated and a connection is established between the first client device and the network.

Systems and methods for creating a database of geofences and registering geofences, with each geofence in the database being associated with an IP address, preferably an IPv6 address. Each geofence is defined using at least one geographic designator, preferably real property boundaries. Entitlements can be associated with geofences relating to permissive and prohibitive activities within the geofences.

Systems and methods of parallel uniform resource identifier resource extraction are provided. A tracking uniform resource identifier (URI) generation component can generate a first uniform resource locator (URL) that, responsive to actuation by a client computing device, causes the client computing device to send a content item identifier of a content item and a device identifier of the client computing device, via a computer network, to a records server at a first network location identified by the first URL. A resource URI generation component can generate a second URL that, responsive to actuation by the client computing device, causes the client computing device to retrieve, via the computer network, a first resource from a second network location identified by the second URL for display by the client computing device. A content item packaging component can generate the content item.

A synchronization protocol for multi-premises hosting of digital content items. In an embodiment, a method includes receiving a first commit request including a first set of one or more identifiers of one or more first content item blocks. The one or more first content item blocks make up a content item stored at a computing device. Further, the method includes, based at least in part on the first commit request, determining a second set of one or more identifiers that includes one or more identifiers of the first set of one or more identifiers not yet stored at a content item block server. The method also includes sending, to the computing device, the second set of one or more identifiers, and receiving a second commit request including the first set of one or more identifiers of the one or more first content item blocks, and an identifier of the content item block server. In this embodiment, the method then includes determining that no content item block from the one or more first content item blocks is missing at the content item block server, and committing the content item to the content item block server.

Systems and methods for creating a database of geofences and registering geofences, with each geofence in the database being associated with an IP address, preferably an IPV6 address. Each geofence is defined using at least one geographic designator, preferably real property boundaries. Entitlements can be associated with geofences relating to permissive and prohibitive activities within the geofences.

A method and apparatus for delivering requested content over a network is described. The method includes receiving, by a first network node, a request from a second network node for the requested content, the request comprising an IPv6 address associated with the requested content. A longest prefix match is then performed between the IPv6 address associated with the requested content and IPv6 addresses associated with content available at the first network node. In the event that the longest prefix match does not result in an exact match between the IPv6 address associated with the requested content and any of the IPv6 addresses associated with content available at the first network node, the request is routed towards a content variant suitable for transcoding to the requested content, the content variant being stored at the first network node.

Systems and methods may provide for confirming, by a loader module having administrative rights with respect to a computing device, the operability of an activator module on the computing device. Additionally, the activator module may be used to manage an installation status of one or more service agents or software components on the computing device and making them persistent. In one example, confirming the operability of the activator module includes conducting a presence verification and/or authentication of the activator module, wherein a replacement activator module may be downloaded to the computing device if the presence verification and/or authentication is unsuccessful.

A peer-to-peer synchronization protocol for multi-premises hosting of digital content items. In one embodiment, for example, a method comprises the operations of: receiving, from a peer computing device, a peer download advertisement comprising an identifier of a content item namespace in association with a peer client journal cursor value; receiving, from a server, one or more server journal entries, each identifying one or more content item blocks of a content item represented by the server journal entry and each having a server journal cursor value; and for at least one server journal entry, downloading, from the peer computing device, at least one content item block of the content item represented by the server journal entry that is not already stored at the computing device.

A first electronic apparatus is provided including a communicator configured to communicate with at least one among a plurality of electronic apparatuses respectively assigned with main resource identifiers for identifying the apparatuses over a network and a controller configured to assign a sub resource identifier, which corresponds to a main resource identifier of a second electronic apparatus and has a smaller unit size than the main resource identifier, to the second electronic apparatus, transmit the assigned sub resource identifier to the second electronic apparatus which the second electronic apparatus stores, use the assigned sub resource identifier of the second electronic apparatus to request communication with the second electronic apparatus, begin communication with the second electronic apparatus if the second electronic apparatus responds to the request for communication, and perform an operation of the second electronic apparatus based on a command from the first electronic apparatus.

Techniques for efficient roaming of clients between access points (APs) of a wireless data communications network are described. A first AP can receive a request for the first client to join the network. The request can specify a unique identifier for the first client. An identifier for a second AP can be determined by processing the unique identifier for the first client using a predefined hash function. A network address of the second AP can be determined using the determined identifier for the second AP. The first AP can transmit a request to the determined network address of the second AP to query for network state information corresponding to the first client, and upon receiving a pairwise master key (PMK) associated with the first client, can authenticate the first client to join the network.
