摘要： A data processing system with intercepting instructions comprising an operating system for supporting processes, such that the process are associated with one or more resources and the operating system being arranged to police the accessing by processes of resources so as to inhibit a process from accessing resources with which it is not associated. Part of this system is an interface for interfacing between each process and the operating system and a memory for storing state information for at least one process. The interface may be arranged to analyze instructions from the processes to the operating system, and upon detecting an instruction to re-initialize a process cause state information corresponding to that pre-existing state information to be stored in the memory as state information for the re-initialized process and to be associated with the resource.

摘要： A method for receiving packet data by means of a data processing system having a plurality of processing cores and supporting a network interface device and a set of at least two software domains, each software domain carrying a plurality of data flows and each supporting at least two delivery channels, the method comprising: receiving at the network interface device packet data that is part of a particular data flow; selecting in dependence on one or more characteristics of the packet data a delivery channel of a particular one of the software domains, said delivery channel being associated with a particular one of the processing cores of the system; and mapping the incoming packet data into said selected delivery channel such that receive processing of the packet is performed by the same processing core that performed receive processing for preceding packets of that data flow.

摘要： Roughly described, incoming data packets are delivered by the NIC directly to at least two user level endpoints. In an aspect, only filters that cannot be ambiguous are created in the NIC. In another aspect, the NIC maintains a filter table supporting direct delivery of incoming unicast and multicast data packets to one user level endpoint. Additional requests to join the same multicast group cause replacement of the NIC filter with one in the kernel. In another aspect, a NIC has limited capacity to maintain multicast group memberships. In response to a new multicast filter request, the kernel establishes it in the NIC only if the NIC still has sufficient capacity; otherwise it is established in the kernel.
摘要翻译： 粗略描述，传入数据分组由NIC直接传递到至少两个用户级端点。 在一方面，仅在NIC中创建不能模糊的过滤器。 另一方面，NIC维护一个过滤表，该过滤表支持将一个单播和多播数据包直接传送到一个用户级端点。 加入同一组播组的其他请求会导致内核中的NIC过滤器的更换。 另一方面，NIC具有维持多播组成员身份的能力有限。 响应于新的多播过滤器请求，内核仅在NIC仍然具有足够的容量时才在NIC中建立它; 否则它在内核中建立。

摘要： A computer system comprising hardware including a data interface for interfacing between the computer system and a data source; a memory; a first operating system capable of communicating with the hardware; and a second operating system capable of supporting a user-level application and being configured to communicate with the hardware via the first operating system, the second operating system being capable of allocating a region of the memory for use as a buffer by such a user-level application. The data interface is configurable to associate a predetermined data format with a region of the memory that has been allocated for use as a buffer by a user-level application supported by the second operating system and to, on receiving from the data source a data message of that format, automatically store data of that message in that region of the memory without it passing via the first or second operating systems.
