    摘要： An interface module is provided for connecting a data communications link to a switching node, comprising a plurality of other interface modules, of a data communications network. The interface module has at least one external port for connection to a data communications link, and a plurality of internal ports for connection to respective internal ports of the switching node. A link interface is connected to the external port for processing inbound and outbound data. A switch circuit is connected between the link interface and the internal ports of the module for transmission of data between the internal ports and to the link interface. The module includes a controller for controlling routing of data via the internal ports in accordance with an intra-node routing protocol. Switching nodes comprising a plurality of interface modules, and optionally one or more switching modules, are provided.

    摘要： A method and system for protection and security of IO devices using credential are provided. The system may include at least one consumer arranged to initiate IO requests from the IO device, and the IO requests may include IO capability allocation and additional parameters. The system may also include an IO resource manager (IORM) arranged to translate the IO capability allocation and additional parameters included in said IO request to a set of capability tokens for the consumer or for a group of consumers, to generate a global key to protect the capability tokens, and further arranged to manage the IO device. The system may further include a channel component arranged to transfer and receive the IO request to and from the IO device.

    摘要： A computer-implemented method for protecting a memory is provided. The method includes responsive to a direct memory access (DMA) request received from a consumer for a transaction of data from an IO device to the memory, the request including an IO command and a capability (CAP), generating a cryptographically signed capability (CAPB), forming a credential from CAP and CAPB, appending the credential to the IO command, configuring the IO device according to the credential and the IO command, transmitting the data from the IO device to the memory and prior to allowing execution of the DMA, authenticating that the credential is valid, further includes regenerating CAPB from a key available to an authenticating entity and from the CAP (included in CAPB) and verifying that the memory region information described in the cryptographically signed capability is the same as the requested region that was originally created, and that the cryptographically signed capability encompasses the IO command.
