The present invention provides a data processing method and device. A data processing device receives a first data stream, where the first data stream includes a first data unit; obtains a boundary of the first data unit; obtains a first skew according to a first data amount and the boundary of the first data unit; and adjusts the first data stream according to the first skew, so that a difference between the boundary of the first data unit and a boundary of the first data amount is a length of an integral quantity of first data units, so that a relatively small amount of data is needed in such an adjustment, that is, one data stream is adjusted, and an adjusted data stream can meet a basic condition for multiplexing, which reduces operation complexity and costs and is beneficial to deploy and implement bit width conversion.

The communication method comprises transmitting a transfer command to transfer the data control, which enables execution of controlling data stored in one or more communication devices connected to at least one of the first and second master devices, from the first master device to the second master device through a first communication line, transmitting a response to the transfer command from the second master device to the first master device through the first communication line, and transmitting a confirmation notification for the response from the first master device to the second master device through the first communication line. The execution of controlling data in the first master device is stopped when the first master device has transmitted the confirmation notification, and the execution of controlling data in the second master device is enabled when the second master device has received the confirmation notification.

The invention relates to network nodes comprising: a first computing unit (CPU.sub.a); at least one second computing unit (CPU.sub.b); an internal switch (Sw.sub.i); and an external switch (Sw.sub.e), wherein the internal switch (Sw.sub.i) is connected to the first computing Nunit (CPU.sub.a), the at least second computing unit (CPU.sub.b) and to the external switch (Sw.sub.e) and wherein the external switch (Sw.sub.e) has at least one port for data originating from other network nodes. The invention also relates to a control module and an Ethernet ring.

Determination of one or more timing (phase) and/or frequency corrections to be made to a local time base of a receiver device to synchronize the local time base with the time of GPS or other highly accurate time base. Timing packets from one or more grandmaster devices whose time bases are substantially the same as that of GPS or the like and/or positioning system signals (e.g., GPS signals) directly from a positioning system are received and manipulated to determine the timing and/or frequency corrections. The corrected time base may be used to assist in acquiring such positioning signals to allow for higher accuracy correction and/or for downstream communication operation. The present utilities are advantageous such as when a sufficient number of channels (e.g., four) from the receiver device to positioning system satellites are unavailable to synchronize the local time base to the GPS or other accurate time base.

A replay device includes: multiple transceiver units that transmits and receives a communication frame, each transceiver unit including a register in which at least data indicating a set-up content relating to an operation of a respective transceiver unit is written; a register access unit that is connected with each transceiver unit through an interface; and a control unit that transmits a control message to the register access unit. The control message includes access target information for designating one or more access target transceiver units, and access content information indicating an access content to a register of each access target transceiver unit. The register access unit sets the one or more target transceiver units designated by the access target information, and perform an access to the register of each access target transceiver unit according to the access content.

An interfabric link between two separate Fibre Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. This translation is preferably done using a private to public loop address translation. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. The virtual switches are then interconnected using private loops. The use of the private loop is enabled by the presence of translation logic which converts fabric addresses to loop addresses and back so that loop and fabric devices can communicate. Because each port can do this translation and the private loop addressing does not include domain or area information, the change in addresses between the fabrics is simplified. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. Thus the private to public and public to private translations are done at the external ports rather than the internal ports as in the prior embodiment. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric, connected to the other fabrics by the private loops.
