摘要： Optimized indication signals of a completed data frame transfer are generated by a network adapter which reduces host processor interrupt latency. The network adapter comprises network interface logic for transferring the data frame between the network and a buffer memory and host interface logic for transferring the data frame between the buffer memory and the host system. The network adapter further includes threshold logic where a threshold value in an alterable storage location is compared to a data transfer counter in order to generate an early indication signal. The early indication signal may be used to generate an early interrupt signal to a host processor before a transfer of a data frame is completed. The network adapter also posts status information status registers which may be used by the host processor to tune the timing of the generation of the network adapter interrupt signal.

摘要： A network interface controller controls communication between a host system and a network transceiver coupled to a network comprises a memory outside of the host address space in which receive and transmit buffers are managed, host interface logic emulating memory mapped registers in the host address space, for transferring data between the host address space and the buffer memory, and network interface logic coupled with the network transceiver, for transferring data between the buffers in the buffer memory and the network transceiver. The buffer memory includes a transmit descriptor ring buffer, transmit data buffer, transfer descriptor buffer, and receive ring buffer all managed by operations transparent to the host.

摘要： Early initiation of transmission of data in a network interface that includes a dedicated transmit buffer is provided in a system which includes logic for transferring frames of data composed by the host computer into the transmit buffer. The amount of data of a frame which is downloaded by the host to the transmit buffer is monitored to make a threshold determination of an amount of data of the frame resident in the transmit data buffer. The network interface controller includes logic for initiating transmission of the frame when the threshold determination indicates that a sufficient portion of the frame is resident in the transmit buffer, and prior to transfer of all of the data of the frame into the transmit buffer. The monitoring logic includes a threshold store, which is programmable by the host computer for storing a threshold value. Thus, the threshold value may be set by the host system to optimize performance in a given setting.

摘要： Indication and interrupt signals generated by a network adapter representing asynchronous events are managed by a host system. The network adapter includes a first mask logic for selectively disabling the indication signals from being stored in a first memory location by the host writing to a first mask register. A second mask logic which is coupled to the first memory location also selectively disables the indication signals from being stored in a second memory location creating two levels of status information. The indication signals may also be disabled from being stored in the second memory location responsive to the host writing to a second mask register. The first memory location may be read from the host in order to determine whether a network event occurred during an interrupt service routine, while interrupt means generates an interrupt signal to the host responsive to the value in the second memory location. A third level of control is provided by an internal counter which allows for automatic enabling and/or disabling of a plurality of indications and interrupts with and without explicit commands in the host driver subroutines.

摘要： A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and using the shared state information to respond to resource failures within the logical group. By sharing state information within the logical group of stream servers, stream servers with the shared state information can quickly take over the active streams from a failed stream server within the logical group. The quick transition of responsibility from one stream server to another enables the streaming network to provide continuous streaming of digital video content to the viewer without interruption.

摘要： In a digital video network that is capable of distributing digital video content to a client via multicasting and unicasting, servicing a channel change request from a client involves switching from providing the digital video content to the client via multicasting to providing the digital video content to the client via unicasting and continuing to provide digital video content to the client via unicasting until a pre-established condition is met. Continuing to provide digital video content to the client via unicasting until a pre-established condition is met allows the network to opportunistically switch the client from unicasting back to multicasting.

摘要： A technique for transitioning streamed digital video content between stream servers involves identifying a transition identifier that indicates a point at which streaming of the digital video content transitions from a first stream server to a second stream server and then transitioning the streaming from the first stream server the second stream server at a point in the digital video content that corresponds to the transition identifier. For example, the first stream server stops streaming the digital video content at a point in the digital video content that corresponds to the transition identifier and the second stream server starts streaming the digital video content at a point in the digital video content that corresponds to the transition identifier.

摘要： A technique for streaming digital video content to a client involves providing a new stream of digital video content to the client using forward error correction (FEC) for a limited initial period and then ending the use of FEC after the limited initial period has ended. In an embodiment, during the limited initial period, the digital video content is provided to the client at a rate that is slightly higher than the playout rate in order to allow a client buffer to accumulate digital video content. FEC continues to be used until the client buffer is sufficiently populated such that lost or damaged frames can be retransmitted to the client before the corresponding digital video content is needed for playout. Once the client buffer is sufficiently populated, FEC is ended and retransmission is used to maintain the quality of the streamed digital video content.

摘要： A method allows a designer to implement software for a wide variety of variant host architectures, without excessive usage of host memory, nor sacrificing the capabilities of high end versions of the variant architectures available. The method is based on providing an initialization module of the software to host memory. A portion of the initialization module determines the host architecture. Based on the determined host architecture, the unneeded portions of the initialization module are freed, and the needed portions are relocated into a contiguous memory space to minimize host memory usage. Any location dependent entries in the needed portions of the program are then updated based on the relocation. The initialization module includes a plurality of code blocks, each of which is optimized to a particular variant architecture. When the variant architecture of the host is identified, those code blocks which are optimized to the identified host are selected and the other code blocks are freed. The selected blocks are then relocated to optimize host memory usage.
