Abstract: A method for providing an interface to a Bluetooth compliant device can emulate a modem such that computer software programs can communicate through the Bluetooth compliant device in the same manner in which they would communicate through a standard modem to access a dial-up, wide area network. The method also supports an interface to a Bluetooth compliant device which can emulate a network socket such that computer software programs can communicate through the Bluetooth compliant device seemingly in the same manner in which they would communicate through a standard network interface card to access a local area network. The method also allows for the interface to a Bluetooth compliant device to be dependent on the nature of the Bluetooth compliant device.

Abstract: The invention provides quality-of-service (QoS) delivery services over a computer bus having isochronous data transfer capabilities. A transmitting node on the bus transmits a message to an intended recipient indicating a requested bandwidth for a connection. If the intended recipient has sufficient resources, it allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits the data on the allocated channel. If the recipient cannot allocate a channel, it does not respond, and the transmitter thereafter detects a time-out condition and begins transmitting using a “best efforts” scheme (i.e., non-guaranteed time delivery). In a second variation, a receiving node detects that it is receiving large quantities of data from a transmitting node. In response, the receiving node allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits using the allocated isochronous channel. In a third variation, multiple receiving nodes that need to receive streaming data from a single transmitting node share a common isochronous data channel. In any of these variations, each receiver can periodically transmit a “deadman” timer message on a broadcast channel to indicate that it is still receiving on a given channel. If a transmitter detects that the deadman timer has expired, it reverts to transmitting data using a “best-efforts” scheme. A transmitter can transmit both to receivers that can handle QoS services and those that cannot explicitly support QoS services.

Abstract: Applications can transparently use a bus, such as the IEEE-1394 serial bus, as if it were an Ethernet (IEEE 802.3). In a conventional Ethernet, each node is assigned a unique 6-byte MAC address in order to receive frames addressed to it over the LAN. According to the invention, IEEE-1394 bus node identifiers are mapped to Ethernet MAC addresses using for example a digital signature algorithm. Ethernet frames are then “wrapped” into 1394 bus packets and addressed to the destination node using the hashed address. The receiver unwraps the 1394 packet and restores the Ethernet frame to its original form. An optimum packet size for transmission of Ethernet packets over the 1394 bus is selected with reference to speed topology maps in the 1394 bus nodes, and this optimum size is transmitted to bus nodes. This packet size is reported to TCP to specify the packet size, and all packets larger than that size are fragmented and reassembled at the receiving node. The protocol works transparently across networks that are linked via bridges.

Abstract: Methods are provided that allow high-level protocol drivers to cancel transmission requests that have been sent to low-level protocol drivers. Transmission requests are assigned cancel identifiers. Because one original request may be divided into several packets for transmission, the same cancel identifier is given to every packet that derives from the original request. High-level protocol drivers can request cancellation of all pending requests whose cancel identifiers match the one indicated. Cancel identifiers generated by different high-level protocol drivers are mutually distinct so one protocol driver cannot inadvertently cancel requests made by another. The protocol driver may divide its requests into logical flows and assign the same cancel identifier to all requests within one flow. Then, the protocol driver may cancel all pending requests within one flow while allowing requests in other flows to proceed to transmission. An application can use these methods to cancel requests sent to high-level protocol drivers.

Abstract translation: 提供了允许高级协议驱动程序取消已发送到低级协议驱动程序的传输请求的方法。 传输请求被分配取消标识符。 由于一个原始请求可能被划分成若干分组用于传输，所以对于从原始请求导出的每个分组，给出相同的取消标识符。 高级协议驱动程序可以请求取消其取消标识符与指定的请求相符的所有待处理请求。 取消由不同的高级协议驱动程序生成的标识符是相互不同的，因此一个协议驱动程序不能无意中取消由另一个执行的请求。 协议驱动程序可将其请求划分为逻辑流，并将相同的取消标识符分配给一个流中的所有请求。 然后，协议驱动程序可以取消一个流中的所有未决请求，同时允许其他流中的请求进行传输。 应用程序可以使用这些方法来取消发送到高级协议驱动程序的请求。

Abstract: A new method and framework for scheduling receive-side processing of data streams received from a remote requesting client by a multiprocessor system computer is disclosed. The method receives data packets from the remote requesting client via a network and, for each data packet, applies a mapping algorithm to portions of the received data packet yielding a mapping value. The method further applies the map value to a processor selection policy to identify a processor in the multiprocessor system as a selected processor to perform receive-side processing of the data packet. The method queues the received data packet for processing by the selected processor and invokes a procedure call to initiate processing of the data packet.

Abstract: Filtering data packets in a manner that promotes efficient flow of data through a communication path. A filter stack includes one or more filter instances that may filter data packets that pass through the filter stack. The filter stack is associated with one or more protocol stacks that function in communication paths between a computing device and a network. When filtering instances are inserted to or removed from a filter stack, associated protocol stacks may remain capable of transferring data. An abstract interface facilitates inserting and removing filter instances by passing data to filter drivers that create filter instances. A filter driver may create multiple filter instances. Filtering operations associated with filter instances may be bypassed based on the direction of data flow, control flow, and characteristics of packets.
