The present invention relates to the field of network communications. An Optical Line Terminal (OLT) allocates a Pseudo Wire (PW) label of an access segment PW for a port, and establishes a corresponding relationship between the port information and the PW label; and carries the corresponding relationship between the port information and the PW label in a label management message, and sends the label management message to an Optical Network Unit (ONU) so that the ONU updates a forwarding table, in which the label management message adopts an access network management protocol. As a consequence, a problem of supporting Pseudo Wire Emulation Edge-to-Edge (PWE3) on a data plane of an access segment of an access network is solved under the conditions that device complexity of the ONU is not increased and a configuration of the ONU is slightly changed.

A system and method for pre-fetching data from system memory. A multi-core processor accesses a cache hit predictor concurrently with sending a memory request to a cache subsystem. The predictor has two tables. The first table is indexed by a portion of a memory address and provides a hit prediction based on a first counter value. The second table is indexed by a core number and provides a hit prediction based on a second counter value. If neither table predicts a hit, a pre-fetch request is sent to memory. In response to detecting said hit prediction is incorrect, the pre-fetch is cancelled.

A method and apparatus for performing efficient interprocess communication (IPC) in a computer system. With this invention, a memory region called the IPC transfer region is shared among all processes of the system to enable more efficient IPC. The unique physical address of the region is mapped into a virtual address from each of the address spaces of the processes of the system. When one of the processes needs to transfer data to another of the processes, the first process stores arguments describing the data in the region using the virtual address in its address space that maps into the unique physical address. When the other or second process needs to receive the data, the second process reads the data from the second region using the virtual address in its memory space that maps into the unique physical address. With this invention, in most cases, control of the IPC transfer region occurs automatically without any kernel intervention.
