A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers.

A communication apparatus, a control program of the communication apparatus, and a relay apparatus are provided. The communication apparatus is configured to download electronic data from a server storing a first amount or more of electronic data and to output the downloaded electronic data. The communication apparatus includes an output unit configured to output a second amount of electronic data smaller than the first amount at one time, a download information acquiring unit configured to acquire download information necessary for downloading the first amount of electronic data stored in the server, from the server, a download unit configured to download the second amount of electronic data of the first amount of electronic data from the server, using the download information acquired by the download information acquiring unit. The output unit is configured to output the electronic data downloaded by the download unit.

Methods, systems, and devices may be used to support freshness-based processing of requests. Freshness-based processing may involve the service layer examining the age of stored content (e.g., resource representation) that it hosts and determining whether it is fresh enough to satisfy a retrieve or discovery request with a specified freshness requirement. If not fresh, the service layer can contact an application to refresh the content. In addition, freshness-based processing can also involve the service layer examining the semantic state of a command oriented update request to determine whether its state is fresh or not with respect to prior commands processed by the service layer. For example, the service layer may compare stored content associated with controlling a particular application (e.g. door is locked) and against the semantic content of an update request (e.g., unlock door) to determine whether it is the same (e.g., stale) or not (e.g., fresh). If fresh, the service layer can then re-target the update request to an application to have it perform the command (e.g., unlock door).

A disclosed apparatus obtains emergency data for multiple device types from a plurality of emergency data sources and provides a jurisdictional map view to a plurality of emergency network entities, where each emergency network entity corresponds to a given geographic boundary. The jurisdictional map view corresponds to a respective emergency network entity's geographic boundary. The apparatus determines portions of the emergency data corresponding to emergencies occurring within each respective emergency network entity geographic boundary, and provides location indicators within each respective jurisdictional map view, with each location indicator corresponding to an emergency.

Systems and methods are disclosed to implement an endpoint command invocation system (“ECIS”). In some embodiments, ECIS can quickly dispatch a command to a large number of endpoint components, where the endpoint components are online. ECIS can receive an invocation of a command, which can include the command recipients. In some embodiments, ECIS determines that some of the command recipients are online, while some of the command recipients are offline. ECIS determines connections to the online command recipients based on a connection map, which is updated whenever an endpoint component opens a connection to ask for a command. ECIS can deliver the command to the online command recipients using the connections. ECIS can also deliver the command to dispatch queues corresponding to the offline command recipients, where the dispatch queues store the command as a pending command that can be delivered to their respective command recipients whenever they come online.

A method for a proxyless protocol includes intercepting, from a client, a first Transmission Control Protocol (TCP) connection request requesting to establish a TCP connection between the client and a proxy for routing data to a destination server. The request includes client information and a first sequence number. The method also includes transmitting, to the destination server, a second TCP connection request to establish a TCP connection between the client and the destination server. The second request includes a second sequence number less than the first sequence number. The method also includes intercepting, from the destination server, an acknowledgment message indicating acknowledgment of the second TCP connection request. The method also includes transmitting, to the destination server, a proxy protocol header message with the client information. The method also includes generating a new acknowledgment message using the first TCP connection request and transmitting, to the client, the new acknowledgment message.

In a communication system, a first mediation apparatus includes a first control device. The first control device stores in a memory a correlation database correlating a mediation apparatus ID of the second mediation apparatus with a first device ID of a device. The first controller requests a management server to register the first device ID, and receives a first command from the management server. The first controller transmits a second command to the second mediation apparatus through the firewall by using a series of procedures. The second command includes second instruction information based on the second command. The first controller transmits a first response to the management server. The second mediation apparatus includes a second control device to initiate the series of procedures and transmits a third command based on the second command to the device, and transmits a second response as to the first mediation apparatus through the firewall.
