Abstract: An operating method of a routing device, a routing device and a terminal device, where the routing device includes a first system and a second system, and the method includes acquiring, by the first system, a first application programming interface (API) call request, where the first API call request is sent by an application program running in the first system, converting, by the first system, the first API call request into a second API call request matching the second system, sending the second API call request to the second system, and executing, by the second system, the second API call request. Hence, difficulty of developing the application program on the routing device can be reduced.

Abstract: A memory management method implemented by a requesting node includes sending first indication information used for indicating a length of memory required by the requesting node and receiving second indication information used for indicating first remote memory provided to the requesting node by a target contributing node in at least one contributing node that can provide remote memory. The method also includes determining, from available virtual addresses, a first virtual address corresponding to the first remote memory, and sending a first data read/write instruction for the first data when first data whose pointer is within a range of the first virtual address needs to be read/written, where the first data read/write instruction includes third indication information, and the third indication information is used for indicating storage space, for storing the first data, in the first remote memory.

Abstract: A method and an apparatus for determining a physical address are disclosed. According to the present disclosure, a page size is obtained according to the higher-order N bits of a linear address, where N is greater than 0 and less than a quantity of bits of the linear address; an index number of a translation lookaside buffer TLB is obtained according to the page size; a mask is obtained according to the page size and a supported minimum page size; a label of the TLB is obtained according to the mask; the higher-order MAC1 bits of a physical address corresponding to the linear address are obtained by searching the TLB according to the index number and the label; and the physical address is obtained according to the mask, the supported minimum page, and the higher-order MAC1 bits of the physical address.
