Abstract: A single-wire communication bus couples a transmitting device to a UART in a receiving device. Flow control circuitry in the UART fills a transmit memory buffer with remote data. The UART supplies a remote start bit onto the single-wire bus for each byte of remote data written into the transmit memory buffer. After detecting a remote start bit on the single-wire bus, the transmitting device supplies initial data bits and a stop bit, which together form an RS232 character. Data flow is controlled when the UART supplies a subsequent remote start bit only after data has been read out of the UART freeing up bytes in a receive memory buffer. After the transmitting device detects the subsequent remote start bit, the transmitting device supplies subsequent data bits onto the single-wire bus. In another embodiment, flow control circuitry functionality is performed by flow control code in the receiving device operating system.

Thus, embodiments of the present invention allow a maximum data rate that can be sustained on a DSL loop without an excessive quantity of errors.

Abstract: Splintered offloading techniques with receive batch processing are described for network acceleration. Such techniques offload specific functionality to a NIC while maintaining the bulk of the protocol processing in the host operating system (“OS”). The resulting protocol implementation allows the application to bypass the protocol processing of the received data. Such can be accomplished this by moving data from the NIC directly to the application through direct memory access (“DMA”) and batch processing the receive headers in the host OS when the host OS is interrupted to perform other work. Batch processing receive headers allows the data path to be separated from the control path. Unlike operating system bypass, however, the operating system still fully manages the network resource and has relevant feedback about traffic and flows. Embodiments of the present disclosure can therefore address the challenges of networks with extreme bandwidth delay products (BWDP).

Abstract: Assignment of network addresses, e.g., IP addresses, to network nodes in a passive optical network (PON) may involve assignment of IP addresses within a common subnet scope to network nodes coupled to different optical fiber links and different interface modules in the PON. In this manner, excessive waste of IP addresses can be avoided. Instead of assigning an entire subnet scope of addresses to the nodes coupled to a single optical fiber link, a common subnet can be allocated across a PON having multiple, independent interfaces, increasing the number of subnet IP addresses that are actually used. Accordingly, the IP address space within a subnet scope can be distributed more efficiently. In addition to conserving IP addresses, the number of subnets allocated by ISPs can be reduced, along with the significant expense incurred by ISPs in reserving and maintaining multiple class C subnets.
