Service path switching method and related device

A service path switching apparatus, comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing instructions, that, when executed by the at least one processor, cause the apparatus to:
• determine a first internet protocol (IP) link associated with service traffic when it is detected that the service traffic needs to be switched from a first optical layer path to a second optical layer path, wherein both the first optical layer path and the second optical layer path are optical layer paths of the first IP link;
• adjust an IP link used to transmit the service traffic from the first IP link to a second IP link, so that the service traffic is adjusted from the first optical layer path of the first IP link to a third optical layer path of the second IP link;
• switch an optical layer path of the first IP link from the first optical layer path to the second optical layer path;
• and
• adjust the IP link used to transmit the service traffic from the second IP link to the first IP link when it is detected that the optical layer path of the first IP link is switched from the first optical layer path to the second optical layer path, so that the service traffic is adjusted from the third optical layer path of the second IP link to the second optical layer path of the first IP link.

A non-transitory storage medium storing a program that, when executed by one or more processors, causes an apparatus to perform operations comprising:

• determining a first internet protocol (IP) link associated with service traffic when it is detected that the service traffic needs to be switched from a first optical layer path to a second optical layer path, wherein both the first optical layer path and the second optical layer path are optical layer paths of the first IP link;
• adjusting an IP link used to transmit the service traffic from the first IP link to a second IP link, so that the service traffic is adjusted from the first optical layer path of the first IP link to a third optical layer path of the second IP link;
• switching an optical layer path of the first IP link from the first optical layer path to the second optical layer path;
• and
• adjusting the IP link used to transmit the service traffic from the second IP link to the first IP link when it is detected that the optical layer path of the first IP link is switched from the first optical layer path to the second optical layer path, so that the service traffic is adjusted from the third optical layer path of the second IP link to the second optical layer path of the first IP link.

A computer program product comprising computer-executable instructions that, when executed by at least one processor, cause an apparatus to:

• determine a first internet protocol (IP) link associated with service traffic when it is detected that service traffic needs to be switched from a first optical layer path to a second optical layer path, wherein both the first optical layer path and the second optical layer path are optical layer paths of the first IP link;
• adjust an IP link used to transmit the service traffic from the first IP link to a second IP link, so that the service traffic is adjusted from the first optical layer path of the first IP link to a third optical layer path of the second IP link;
• switch an optical layer path of the first IP link from the first optical layer path to the second optical layer path;
• and
• adjust the IP link used to transmit the service traffic from the second IP link to the first IP link when it is detected that the optical layer path of the first IP link is switched from the first optical layer path to the second optical layer path, so that the service traffic is adjusted from the third optical layer path of the second IP link to the second optical layer path of the first IP link.
