A method for routing a packet in an accelerator network is provided, the method includes: receiving, by a first accelerator which is any accelerator in an accelerator network, an acceleration request packet which includes an acceleration sequence and to-be-accelerated data from a CPU, the acceleration sequence is used to indicate a plurality of acceleration types used for accelerating the data and indicate an order of the plurality of acceleration types; determining, by the first accelerator, a target loop path of the acceleration request packet based on an acceleration information table which includes location information and acceleration type information of a plurality of accelerators in the accelerator network and accelerators on the target loop path are capable of performing acceleration processing on the acceleration request packet according to an indication of the acceleration sequence; and routing, by the first accelerator, the acceleration request packet according to the target loop path.

Method and apparatus for routing packet in accelerator network

An optical network-on-chip, an optical router, and a signal transmission method. The optical network-on-chip includes: N2 intellectual property IP cores, N2/2 gateways, and N2 optical routers. The N2 optical routers form two subnets, and every N2/2 optical routers form one subnet. Each gateway in the N2/2 gateways is connected to every two IP cores in the N2 IP cores, where IP cores connected to different gateways are different, and the two IP cores connected to each gateway are in one-to-one correspondences with the two subnets. The N2/2 gateways are in one-to-one correspondences with the N2/2 optical routers in each subnet in the two subnets, where each gateway is connected to an optical router that is in each subnet and that is corresponding to each gateway.
