Abstract
A network node configuration method includes obtaining address information of a virtual address segment related to a target physical device, where the target physical device belongs to a second network node, the virtual address segment includes a first virtual address segment and a second virtual address segment, the first virtual address segment belongs to a virtual address space of a first network node and is used by the target physical device to access the first network node, and the second virtual address segment belongs to a virtual address space of the second network node and is used by the first network node to access the target physical device; and configuring an address mapping relationship.
Claims20
A method implemented by a source network node and comprising:
- obtaining a first virtual address from a first access request;
- translating the first virtual address into a first physical address;
- generating, based on the first physical address and a target address mapping relationship, a second access request corresponding to the first access request, wherein when the source network node is a first network node, the target address mapping relationship is a first address mapping relationship and the first access request is for accessing a target physical device in the second network node, and wherein when the source network node is a second network node, the target address mapping relationship is a second address mapping relationship and the first access request is for accessing the first network node;
- and
- sending the second access request to a destination network node.
A source network node comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the source network node to:
- obtain a first virtual address from a first access request;
- translate the first virtual address into a first physical address;
- generate, based on the first physical address and a target address mapping relationship, a second access request corresponding to the first access request, wherein when the source network node is a first network node, the target address mapping relationship is a first address mapping relationship and the first access request is for accessing a target physical device in the second network node, and wherein;
- when the source network node is a second network node, the target address mapping relationship is a second address mapping relationship and the first access request is for accessing the first network node;
- and
- send the second access request to a destination network node.
A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable storage medium and that, when executed by at least one processor of a source network node, cause the source network node to:
- obtain a first virtual address from a first access request;
- translate the first virtual address into a first physical address;
- generate, based on the first physical address and a target address mapping relationship, a second access request corresponding to the first access request, wherein the source network node is a first network node or a second network node, wherein, when the source network node is the first network node, the target address mapping relationship is a first address mapping relationship and the first access request is for accessing a target physical device in the second network node, and wherein, when the source network node is the second network node, the target address mapping relationship is a second address mapping relationship and the first access request is for accessing the first network node;
- and
- send the second access request to a destination network node.
