Abstract: In one embodiment, a system and method include determining bandwidth of a link that connects a local modem to a remote router. A first percentage of the bandwidth is assigned to a first class of data and a second percentage of bandwidth is assigned to a second class of data. The remaining percentage of the bandwidth is assigned for nominal excess capacity. The flow of first class of data and second class of data are controlled to below respective percentages of the bandwidth.

Abstract: An access server communicates with a video conference device and a user device. The access server and the user device may access known mappings, including a default mapping. Each mapping is configured to map between tokens and symbols according to a distinct mapping relationship between the multi-bit tokens and the symbols. The access server instructs the video conference device to map an initial token to an initial symbol based on the default mapping and to transmit the initial symbol. The access server receives from the user device the initial token and a challenge mapping selected by the user device. The access server determines a challenge token that the challenge mapping maps to a challenge symbol, and instructs the video conference device to transmit the challenge symbol. The access server grants the user device access to an information carrying channel only if the challenge token is received from the user device.

Abstract: In a transmit method, a set of data eigenvectors that are based on a Prometheus Orthonormal Set (PONS) code construction and orthogonal to each other are stored, wherein each of the data eigenvectors is mapped to a unique multi-bit word. A pilot sequence representing a pilot eigenvector that is based on the PONS code construction and orthogonal to each of the data eigenvectors is generated. Input data is grouped into multi-bit words and ones of the data eigenvectors mapped to the multi-bit words are selected. A spread data sequence including the selected ones of the data eigenvectors and that is synchronized to the pilot sequence is generated. An acoustic signal including the synchronized pilot sequence and the spread data sequence is generated. The acoustic signal is transmitted.

Abstract: A method that includes: (1) transmitting, at a first transmit time point, a first probe packet over a network connection to a conferencing server immediately before transmitting a data packet, the first probe packet arriving at the conferencing server at a first receive time point; (2) transmitting, at a second transmit time point, a second probe packet over the network connection to the conferencing server immediately after transmitting the data packet, the second probe packet arriving at the conferencing server at a second receive time point, the first and second probe packets being smaller than the data packet; (3) receiving information encoding a first difference between the first and second transmit time points and a second difference between the first and second receive time points; and (4) based on the first and second differences, modifying a transmission parameter associated with data packets to be transmitted thereafter to the conferencing server.

Abstract: A system includes a processor operable to identify each of a plurality of first video packets from a communication session with a first identifier designating that bandwidth is reserved on the network for the packet, and identify each of a plurality of second video packets from the communication session with a second identifier designating that bandwidth is not reserved on the network for the packet. The system further includes an interface operable to initiate transmission of the plurality of first video packets and the plurality of second video packets in the communication session.
