Abstract: A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

Abstract: Methods and systems for a plurality of physical layers for network connection may include coupling a MAC to one of a plurality of PHYs. The coupling to a specific PHY may be based on auto-detection of network activity, or network devices, via the PHYs. Also, one of the PHYs may be coupled to the MAC as a power-up default. The PHYs may be coupled to a same network, by, for example, cables. A first cable to a first PHY may couple it to a first network switch and a second cable to a second PHY may couple it to a second network switch. The first network switch may be rated to handle, for example, a greater data rate than the second network switch. The first cable may not be able to be used as a cable for the second PHY, and vice versa.

Abstract: Methods and systems for latency optimized ATS usage are disclosed. Aspects of one method may include communicating a memory access request using an untranslated address and also an address translation request using the same untranslated address, where the translation request may be sent without waiting for a result of the memory access request. The memory access request and the address translation request may be made in either order. A translation agent may be used to translate the untranslated address, and the translated address may be communicated to the device that made the memory access request. The translated address may also be used to make the memory access. Accordingly, by communicating the translated address without having to wait for completion of the memory access, or vice versa, the requesting device may reduce latency for memory accesses when using untranslated addresses.

Abstract: Certain aspects of a method and system for quality of service and congestion management for converged network interface devices are disclosed. Aspects of a method may include processing at least one of: input/output (I/O) requests and network packets in a converged network interface card (CNIC) based on a class associated with each of the I/O requests and network packets by storing on the CNIC, information that identifies the I/O requests and network packets, without storing on the I/O requests and network packets on the CNIC.

Abstract: Certain aspects of a method and system for protocol offload in paravirtualized systems may be disclosed. Exemplary aspects of the method may include preposting of application buffers to a front-end driver rather than to a NIC in a paravirtualized system. The NIC may be enabled to place the received offloaded data packets into a received data buffer corresponding to a particular guest operating system (GOS). A back-end driver may be enabled to acknowledge the placed offloaded data packets. The back-end driver may be enabled to forward the received data buffer corresponding to the particular GOS to the front-end driver. The front-end driver may be enabled to copy offloaded data packets from a received data buffer corresponding to a particular GOS to the preposted application buffers.

Abstract: Methods and systems for protocol offload and direct I/O with I/O sharing in a virtualized network environment are disclosed. Aspects of one method may include a plurality of GOSs sharing a single network interface circuitry, or a network interface card, (NIC) that may provide access to a network. The NIC may directly handle processing of data to be transmitted to the network and/or data received from the network for each of the GOSs without a TGOS for the GOSs handling the data to be transmitted to the network and/or data received from the network. The data may be copied directly from a buffer in the single NIC to an application buffer for one of the plurality of GOSs and/or directly from an application buffer for one of the plurality of GOSs to the buffer in the single NIC.

Abstract: Methods and systems for direct device access are disclosed. Aspects of one method may include a plurality of GOSs directly accessing a first network interface device, where the first network interface device may provide access to a network. One or more of the GOSs may be migrated to directly access a second network interface device, based on state information for each of the GOSs, where the state information may be maintained by the host. The GOSs may communicate data to a device coupled to the network by direct accessing the first and/or second network interface device. Similarly, the first and/or second network interface device may communicate data received from a device coupled to the network to one or more of the plurality of GOSs via direct access of the first and/or second network interface device.
