20080228946 | DATA TRANSFER, SYNCHRONISING APPLICATIONS, AND LOW LATENCY NETWORKS - Asynchronous network interface and method of synchronisation between two applications on different computers is provided. The network interface contains snooping hardware which can be programmed to contain triggering values comprising either addresses, address ranges or other data which are to be matched. These data are termed “trip wires”. Once programmed, the interface monitors the data stream, including address data, passing through the interface for addresses and data which match the trip wires which have been set. On a match, the snooping hardware can generate interrupts, increment event counters, or perform some other application-specified action. This snooping hardware is preferably based upon Content-Addressable Memory. | 09-18-2008 |
20110040897 | NETWORK INTERFACE AND PROTOCOL - A communication interface for providing an interface between a data link and a data processor, the data processor being capable of supporting an operating system and a user application, the communication interface being arranged to: support a first queue of data received over the link and addressed to a logical data port associated with a user application; support a second queue of data received over the link and identified as being directed to the operating system; and analyse data received over the link and identified as being directed to the operating system or the data port to determine whether that data meets one or more predefined criteria, and if it does meet the criteria transmit an interrupt to the operating system. | 02-17-2011 |

20120124121 | RECEPTION ACCORDING TO A DATA TRANSFER PROTOCL OF DATA DIRECTED TO ANY OF A PLURALITY OF DESTINATION ENTITIES - A data processing system arranged for receiving over a network, according to a data transfer protocol, data directed to any of a plurality of destination identities, the data processing system comprising: data storage (event queues | 05-17-2012 |
20120296952 | RECEPTION ACCORDING TO A DATA TRANSFER PROTOCOL OF DATA DIRECTED TO ANY OF A PLURALITY OF DESTINATION ENTITIES - A data processing system arranged for receiving over a network, according to a data transfer protocol, data directed to any of a plurality of destination identities, the data processing system comprising: data storage for storing data received over the network; and a first processing arrangement for performing processing in accordance with the data transfer protocol on received data in the data storage, for making the received data available to respective destination identities; and a response former arranged for: receiving a message requesting a response indicating the availability of received data to each of a group of destination identities; and forming such a response; wherein the system is arranged to, in dependence on receiving the said message: identify received data that is directed to any destination identity that is both a member of the group and a member of a subset of the plurality of destination identities, and on which processing has not yet been performed; trigger processing by the first processing arrangement in accordance with the protocol on only the identified data; and subsequently form a response based at least partly on the result of the triggered processing, wherein the response is formed so as to comprise a positive indication of availability of data for a destination identity of the group if the triggered processing caused data to be made available to the respective destination identity. | 11-22-2012 |

20130041930 | DATA TRANSFER, SYNCHRONISING APPLICATIONS, AND LOW LATENCY NETWORKS - Asynchronous network interface and method of synchronisation between two applications on different computers is provided. The network interface contains snooping hardware which can be programmed to contain triggering values comprising either addresses, address ranges or other data which are to be matched. These data are termed “trip wires”. Once programmed, the interface monitors the data stream, including address data, passing through the interface for addresses and data which match the trip wires which have been set. On a match, the snooping hardware can generate interrupts, increment event counters, or perform some other application-specified action. The invention thus provides in-band synchronisation by using synchronisation primitives which are programmable by user level applications, while still delivering high bandwidth and low latency. The programming of the synchronisation primitives can be made by the sending and receiving applications independently of each other and no synchronisation information is required to traverse the network. | 02-14-2013 |
20130290558 | DATA TRANSFER, SYNCHRONISING APPLICATIONS, AND LOW LATENCY NETWORKS - Data transfer, synchronising applications, and low latency networks are disclosed. An example method includes comparing a first address of a first data item of a first data burst to a second address of a last data item of a second data burst received before the first data burst; and, when the first address sequentially follows the second address, combining the first and second data bursts to form a third data burst. | 10-31-2013 |
20150081925 | DATA TRANSFER, SYNCHRONISING APPLICATIONS, AND LOW LATENCY NETWORKS - Data transfer, synchronising applications, and low latency networks are disclosed. An example method includes maintaining a first buffer in a first computing device, the first buffer to receive discrete units of data from a second computing device; maintaining a second buffer in the first computing device, the second buffer to store size data identifying a size of respective ones of the discrete units of data received from the second computing device; and reading from the first buffer according to a first value of a first pointer and a corresponding one of the sizes stored in the second buffer. | 03-19-2015 |
