Abstract: Method and apparatus for improving streaming data of graphics remoting applications are described herein. According to one embodiment, a stream of data objects is generated, each data object representing graphics data associated with an image to be rendered at a client over a network. For each data object, it is detected whether the associated image includes a first region and a second region having content with different types of contents based on a changing rate of display output regions. The first region is compressed using a first compression method and the second region is compressed using a second compression method different than the first compression method. The graphics data associated with the compressed first region and second region is transmitted to the client over the network to be rendered at the client. Other methods and apparatuses are also described.

Abstract: A low rate DoS attack detection algorithm is used, which relies on a characteristic of the low rate DoS attack in introducing high rate traffic for short periods, and then uses a proactive test based differentiation technique to filter the attack packets. The proactive test defends against DDoS attacks and low rate DoS attacks which tend to ignore the normal operation of network protocols, but it also differentiates legitimate traffic from low rate DoS attack traffic instigated by botnets. It leverages on the conformity of legitimate flows, which obey the network protocols. It also differentiates legitimate connections by checking their responses to the proactive tests which include puzzles for distinguishing botnets from human users.

Abstract: Various embodiments of systems and methods for data message exchange in a client server network are described herein. In various embodiments, a client and a server network may implement a data message protocol for message exchanges. A method of an embodiment ensures message delivery, acknowledge message delivery, message delivery in a specific order, resending of lost data messages, and the like. In various embodiments, such data exchange may optimize data transmission and resource consumption in a client server network. A server can store data messages in a buffer and resend them only when requested by the client, as in the case of lost or out of sequence data message. A client with limited storage space need not concern itself with storing data messages and processing them at a later point in time. Furthermore, a client may optimize data transmission by acknowledging bulk data messages, rather than acknowledging them individually.

Abstract: Network adapter use of an interface specific buffer is managed so that their combined use with non-interface specific buffers has a reduced impact, such as when an interface specific buffer becomes full. If an attempt fails by a protocol stack of an operating system to buffer information for a packet in an interface specific buffer, an offset marks the end of the use of the interface specific buffer for the packet and a non-interface specific buffer is used to store the remaining information for the packet. During transmission of the packet, the offset is read by a network adapter driver to take advantage of reduced processing for sending information from the interface specific buffer and to identify information that need additional processing for transmission from the non-interface specific buffer.

Abstract: A method for reliably transferring media over a network from a sending node to a receiving node. The method includes ascertaining at the sending node if the media to be transmitted is either time-sensitive or not time-sensitive. For media ascertained as non time-sensitive, the media is transmitted by adjusting the rate of transmission at the sending node based on network conditions. As the non time-sensitive media is received, the receiving node generates one or more low priority requests for the retransmission of any missing non time-sensitive media lost during the transmission. The method also includes transmitting the time-sensitive media from the sending node to the receiving node. As the time-sensitive media is received, the receiving node ascertains if a predetermined acceptable network transmission loss level is met. If met, the receiving node generates one or more low priority requests for the retransmission of any missing time-sensitive media lost during transmission.

Abstract: A method for minimizing latency of data transfer between the redundant storage controllers in a network-based storage controller system that utilizes adaptive data throttling. Each redundant storage controller monitors latency for round trip communications between the redundant controllers by calculating a time required to mirror a write to the other controller and receive a write acknowledge.

If the average time latency is good, the one controller reduces or disables throttling for data transfers between the one controller and the server, and between the one controller and back-end storage, increasing a number of this type of data transfer that can be executed in parallel.
