Resource reservation method and electronic device

An electronic device, comprises:

• a processor and a machine readable storage medium;
• wherein,
• the machine readable storage medium stores machine executable instructions executed by the processor;
• the processor is configured to execute the machine executable instructions to perform the operations comprising:
• determining a virtual periodic forwarding path (VPFP) of a DetNet flow transmitted in a DetNet domain;
• wherein there is a pre-configured static scheduling cycle mapping relationship between any node other than a tail node in the VPFP and a next hop node of the any node;
• the scheduling cycle mapping relationship refers to a mapping relationship between a scheduling cycle of a target egress interface for transmitting the DetNet flow on any node other than the tail node in the VPFP and a scheduling cycle of a target egress interface for transmitting the DetNet flow on a next hop node of the any node;
• wherein the scheduling cycle mapping relationship is an injective function;
• for the target egress interface on each node in the VPFP, planning a target scheduling cycle for scheduling and transmitting the DetNet flow;
• wherein the target scheduling cycle of the target egress interface on any node other than the head node in the VPFP is determined based on the scheduling cycle mapping relationship between a previous hop node of the any node and the any node and the target scheduling cycle of the target egress interface on the previous hop node;
• from an available transmission resource corresponding to the target scheduling cycle of the target egress interface on each node in the VPFP, reserving a target transmission resource for transmitting the DetNet flow within the target scheduling cycle so as to transmit the DetNet flow by the target transmission resource allocated for the target scheduling cycle of the target egress interface on each node in the VPFP.
