Methods, systems, and computer readable media can be operable to facilitate the spoofing of domain name system requests by a customer premise equipment (CPE) device. The CPE device may detect and block a DNS (domain name system) request received from a client device, and the CPE device may generate a DNS response that includes a pre-configured redirect address. The CPE device may block an identified DNS request when the CPE device is unable to retrieve content associated with the DNS request. The CPE device may output the DNS response to the client device from which the DNS request was received, and in response, the client device may output a request on the pre-configured redirect address that is included within the DNS response. The redirect address may direct the client device to an alternate content source.

A method of reducing the bandwidth usage of a network comprises intercepting traffic between a TCP server and a TCP client using TCP protocols that use client acknowledgements; identifying client acknowledgements from the TCP protocols; identifying the sequence number of a last received client acknowledgements from the intercepted traffic; identifying the sequence number of a last sent client acknowledgement from the intercepted traffic; calculating an unacknowledged byte value based on the difference between the last received client acknowledgement sequence number and the last sent client acknowledgement sequence number; comparing the calculated unacknowledged byte value with a predetermined threshold value, to determine whether the calculated unacknowledged byte value is at least as great as the predetermined threshold value; and transmitting the identified client acknowledgements into the network when the compared unacknowledged byte value is at least as great as the predetermined threshold value.

A communication control method comprises: transmitting, by a communication apparatus, a Device to Device (D2D) resource notification to a user terminal. The D2D resource notification includes information indicating a predetermined D2D radio resource available in a D2D proximity service and information indicating a condition not allowing for use of the predetermined D2D radio resource.

A method for controlling data flow by a proxy server connected between a User Equipment (UE) and a content server is disclosed. The proxy server estimates a first amount of data reception indicating an amount of data received by the UE and calculates a second amount of data reception indicating an amount of data received by the proxy server from the content server. The proxy server delays transmission of acknowledgement (ACK) on data received by the proxy server from the content server and waits until a time allowed for the transmission, if the second amount of data reception is greater than the first amount of data reception by a predetermined threshold. The resent disclosure may prevent a waste of network load and unnecessary resources by the proxy server controlling download data rate from the content server.
