Abstract: Apparatuses and methods to mirror frames received at an input port or provided by an output port to a port not connected to the device performing the mirroring operation. A frame being sent to a diagnostic system has a mirror header added to allow the frame to be routed through any intervening switches in the same fabric. The final switch or the diagnostic system removes the mirror header. If the diagnostic system is attached in a different fabric, encapsulation and inter-fabric routing headers are added as needed to the frame containing the mirror header. This allows the frame to traverse multiple fabrics to reach the diagnostic system. The encapsulation and inter-fabric routing headers are removed as done normally. This allows a diagnostic system to be connected to any switch in the network, either in the same or a different fabric.

Abstract: Some bus protocols are useful for management of peripheral devices that exist on a computer's system bus. Such bus protocols include the industry standard architecture bus (ISA), peripheral component interconnect (PCI), PCI express (PCIe), etc. The usefulness of such protocols for control messages, interrupt management and more is limited to the short distances over which the protocols operate, usually measured in inches. The use of longer distance transport protocols, such as Ethernet to encapsulate and transport bus protocol messages allows the advantages of the short distant protocols to be used to control remote devices. A master device, with a controller or processor, may be used to manage the operation of a slave device using the bus or control protocol. Such management may include button presses, indicator lights, slave device configuration, etc. The slave device may have a low cost controller or ASIC to provide real-time operational functions, such as routing.

Abstract: Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available. A first portion of a content file may be pre-delivered to the receiving system so that users may consume the first portion content while the buffer is pre-filled.

Abstract: Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. Content delivery does not impact other users' applications and use of the network and its resources since content is only sent when surplus network capacity exists in the network. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available.

Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to “hopping” of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes.
