Described herein are apparatus, systems and methods for adaptive segment size for data transmissions. A method may comprise, at a user equipment (“UE”), identifying a current size setting of a data segment (e.g., a transmission control protocol (“TCP”) maximum segment size (“MSS”)) for communication over a network, receiving current physical layer conditions, receiving historical data, and adjusting the current size setting based on at least one of the current physical layer conditions and the historical data.

A system for synchronous media rendering over wireless networks with wireless performance monitoring, comprising a media source device and a plurality of destination devices, a quality analysis module operating on at least one of the devices to monitor the media being streamed and direct the operation of a synchronization module, and a synchronization module operating on at least one of the devices to direct the rendering of media data based on received event data and to transmit event data to at least a portion of the destination devices, and a method for common event-based multidevice media synchronization and quality analysis.

The present invention enables packet data to be filtered without distinguishing between non-fragmented packets and fragmented packets. This invention is characterized in that: when received packet data is a fragmented packet but is not a lead fragmented packet, header information of the lead fragmented packet, which has the same fragmented packet identification information as that of the packet data, is given to the packet data as a pseudo-header; the header information of the packet data is used as a key and a filter table is searched in which a filter condition about the header information corresponds to a process implemented when the filter condition is satisfied; the process corresponding to the filter condition satisfied by the header information of the packet data is determined as a process performed for the packet data; and the determined process is performed on the packet data.

A method for timely transmission of first payload of data from sender device to receiver device includes obtaining a first payload of data to be transmitted; slicing at sender device, first payload of data to at least to first fragment of data appended by first fragment metadata jointly forming first fragment of first fragment size, and to second fragment of data appended by second fragment metadata jointly forming second fragment of second fragment size; transmitting, at least first fragment over first communication channel and at least second fragment over second communication channel; receiving, at least first fragment and at least second fragment at receiver device; and reconstructing, at receiver device, first payload of data from at least first fragment using first fragment metadata and first fragment of data or from at least second fragment using the second fragment metadata and the second fragment of data.

In some embodiments, a method receives a packet for a flow from a first application in a first workload to a second application in a second workload. The packet includes an inner header that includes layer 4 information for the first application. The method determines if a setting indicates an outer source port in an outer header should be generated using layer 4 information from the inner header. The setting is based on an analysis of packet types in the flow to determine if fragmented packets are sent. When the setting indicates the outer source port in the outer header should be generated using layer 4 information from the inner header, the method generates the outer source port using the layer 4 information for the first application from the inner header. The packet is encapsulated using the outer header, wherein the outer header includes the outer source port.

Packet protection is described. Data of a group of packets is concatenated with a security key and a sequence number of the packet. A hash mark of the concatenated data is calculated and sent with data or control information in a packet. If each packet has reserved bits, at least some of the packets each has data, a least a portion of the hash mark, and a header having: a first bit that indicates if the hash mark is present, and a second bit that indicates if the packet is used to determine the hash mark. Otherwise, a separate control packet is sent that contains the hash mark, a first sequence number of the group of packets, and a PDU type indicating that the control packet is an integrity protection packet for the group of PDCP packets.

A system and related method exchange messages under the control of a messaging client. The method comprises splitting a content of a source message into a plurality of fragments defined by corresponding portions of its content associated with different recipients of the message. A plurality of transport messages are generated, each comprising one or more of the fragments associated with the recipients. The transport messages are submitted to a messaging server for causing it to provide the transport messages to corresponding further messaging clients of the recipients for their aggregation. A computer program and a computer program product for performing the method are also provided.
