A technique for determining a boundary IP address is disclosed. The technique includes processing a header to extract candidate IP address, locating a gateway IP address, and selecting the boundary IP address based on the location of the gateway IP address.

When a proxy device is used between a transmission terminal and a reception terminal, receives final data from the transmission terminal, and fails immediately thereafter, a situation is avoided where transmission is completed in the transmission terminal, but reception is not completed in the reception terminal. There is provided a means for not returning ACK when a data packet is received in a state in which there is no data which waits for ACK and transmission of which is in progress, and there is no data which waits for arrangement and reception of which is in progress in the proxy device, for returning ACK for data received one step before when a data packet is received in a state in which there is data which waits for ACK and transmission of which is in progress, or there is data which waits for arrangement and reception of which is in progress.

Methods and apparatus for local data caching are disclosed. Data may be stored in a local data storage connected to a base station or network nodes. The data flow may be split. The base station may coordinate with a cooperating base station for split-data transmission of locally cached data. Data may be split at different layers.

Disclosed are methods, circuits, apparatus, systems and functionally associated computer executable code for providing connectivity between a mobile communication device communicatively coupled to an access point of a mobile communication network and a remote server. According to some embodiments, there may be provided a data buffer at or in communicative proximity with the access point and which responds to receipt of data packets from the remote server with a packet receipt acknowledgement emulating a packet receipt acknowledgment of the mobile communication device.

A technique for determining a boundary IP address is disclosed. The technique includes processing a header to extract candidate IP address, locating a gateway IP address, and selecting the boundary IP address based on the location of the gateway IP address.

A system, a method, a device, and a computer program product for transmission of data packets between a user device and a server. A communication link between the user device and the server is established in accordance with a transmission control protocol for transmission of a data packet between the user device and the server. The data packet is transmitted utilizing the transmission control protocol.

A session admission process is provided which identifies the weakest link in a route between a first node and a second node and determines if the route is able to cope if the session is admitted. The suitability of a link is determined on the basis of: historical link performance; the predicted future performance of the link; and the predicted future demands on the link from other sessions supported by that link.

Methods for inserting a middlebox into a network connection include monitoring network state information in a connection between a client and a server. When the connection is idle, a connection entry is created for each device and is initialized using state information gathered by monitoring the network connection. Redirection of the network connection is activated between the client and the server such that the middlebox mediates the connection. Methods for removing a middlebox from a network connection include determining a degree of mismatch between a sequence number in a first connection between the middlebox and a client and a sequence number in a second connection between the middlebox and a server, delaying acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch, and establishing a direct connection between the client and the server without mediation by the middlebox when the degree of mismatch is zero.

A communication system includes: a server configured to transmit a series of data packets through a relay device and a transmitting device to receiving device; the receiving device configured to transmit a plurality of acknowledgement packets for the data packets; the transmitting device configured to provide, when executing link aggregation on a downlink flow including the data packets, a notification that represents that the downlink flow is subjected to the link aggregation; and the relay device configured to: execute a process of concealing a specific acknowledgement packet that is among the plurality of acknowledgement packets and included in an uplink flow corresponding to the downlink flow subjected to the link aggregation and represents that an order in which the data packets arrive at the receiving device is reversed, when receiving the notification from the transmitting device, and transmit the other acknowledgement packets remaining after the concealment process to the server.

A system, method and computer program product for detecting data omissions between intermittently-connected devices. An example system includes physical computing resources available for utilization. A placement server communicates with a client. The client seeks to use a portion of the computer resources to execute the software product instances. The placement server receives resource utilization parameters from the client and assigns the portion of the computer resources to the software product instances based on the resource utilization parameters and the physical computing resources available for utilization. The resource utilization parameters include specification of a hierarchal arrangement of the software product instances.
