Abstract: Embodiments provide an SDN, an SDN configuration method, an SDN-based data transmission method, and a network controller. A data packet combination function and a data packet split function are separately configured on nodes in the SDN. Therefore, when data packets of a first service are received, multiple small data packets of the first service may be combined into one large data packet. In comparison with transmission of the multiple small data packets, transmission efficiency of the SDN can be improved by transmitting the combined data packet.

Abstract: A system and method is provided that recommends group compositions in multiplayer video games. The system may suggest a composition of a group of players using a matchmaking process. For example, one or more players may wish to form or join a group of players for a given game, but not know what would be an appropriate mix of player styles, player roles, skill levels, and/or other player characteristics that would make an optimal group, given the player's own characteristics. The system may identify optimal groups based on matchmaking related information such as, without limitation, game profile, player profile, prior match scores, prior quality scores, and/or other information. Optimal groups may be those that have performed successfully (e.g., accomplished the most wins, objectives, etc.), are associated with the highest player enjoyment (e.g., based on match and/or quality scores), and/or otherwise are deemed to be desirable.

Abstract: A player receives encoded content of a first resolution level from a content retransmitter and monitors bandwidth of the communication connection utilized to receive the content. When the bandwidth changes with respect to various threshold values corresponding to various resolution levels, the player signals the content retransmitter to increase or decrease the encoding resolution for future portions. The player also locates related substitute content. When the player signals the content retransmitter to decrease the resolution below a minimum, the player plays the substitute content instead of the received content. Subsequently when the bandwidth is again such that player signals the content retransmitter to increase the resolution to the minimum or above, the player plays the received content instead of the substitute content. In various implementations, the player may obtain substitute content prior to or at the time the player determines to play substitute content.

Abstract: During unfavorable network conditions, a system provides a fallback mode that ensures conversation intelligibility and eliminates dropouts. In the fallback mode, the system uses data retransmission and mitigates retransmission delay by breaking input and output audio into segments for flow control and by involving the users in flow control. On the receive end, when necessary, the system pauses audio output and indicates the pause to the receiving user to inform the receiving user that the pause is a system artifact rather than silence from the transmitting user. On the transmit end, when necessary to avoid accumulation of excessive end-to-end delay, the system suspends audio input and indicates the suspension to the transmitting user to inform the transmitting user that audio input is temporarily being ignored. The transmit end of the system decides when to suspend audio input based on current end-to-end delay, which is continually communicated from the receive end.
