Abstract: A network interface device has an input configured to receive data from a network. The data is for one of a plurality of different applications. The network interface device also has at least one processor configured to determine which of a plurality of available different caches in a host system the data is to be injected by accessing to a receive queue comprising at least one descriptor indicating a cache location in one of said plurality of caches to which data is to be injected, wherein said at least one descriptor, which indicates the cache location, has an effect on subsequent descriptors of said receive queue until a next descriptor indicates another cache location. The at least one processor is also configured to cause the data to be injected to the cache location in the host system.

Abstract: A method is disclosed for bridging between a first data link carrying data units of a first data protocol and a second data link for carrying data units of a second protocol by means of a bridging device. This method may comprise receiving by means of a first entity data units of a first protocol, and storing those data units in the memory. Then, accessing by means of a protocol processing entity the protocol data of data units stored in the memory and thereby performing protocol processing for those data units under the first protocol. The method also accesses by means of a second interface entity the traffic data of data units stored in the memory and thereby transmits that traffic data over the second data link in data units of the second data protocol.

Abstract: A data processing system with routing tables 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.

Abstract: A logic device and method are provided for intercepting a data flow from a network source to a network destination. A data store holds a set of compliance rules and corresponding actions. A packet inspector is configured to inspect the intercepted data flow and identify from the data store a compliance rule associated with the inspected data flow. A packet filter is configured to, when the data flow is identified as being associated with a compliance rule, carry out an action with respect to the data flow corresponding to the compliance rule.
