A method and system for optimizing first-diffraction-order reconstruction of holograms, a device, and a medium are provided. The method includes: acquiring a target image; determining a target image light field according to the target image; calculating a target diffraction field for the target image light field by performing backward propagation by a set distance; constructing a U-Net network model; and inputting the target diffraction field into a trained U-Net network model to acquire an optimized hologram. The trained U-Net network model is obtained by constructing a U-Net network model and training and optimizing the U-Net network model, thereby continuously improving the quality of the zero-diffraction-order reconstructed image of the initial hologram and finally achieving the effect of optimizing the first-diffraction-order reconstructed image of the hologram.

Method and system for optimizing first-diffraction-order reconstruction of holograms, device and medium

A method of determining an optimal route for communication between nodes in a communications network. The method comprises assigning a plurality of link potential values (P) to a respective plurality of direct links (l) between respective first and second nodes a and b in the network, wherein a link potential value (P) represents a likelihood that the corresponding direct link will be used for future communication requests. The method comprises determining an optimal route between nodes based on the plurality of link potential values (P).

Optimal routing in a communications network

A technique for triggering an association between a Media Access Control (MAC) address and a switch port is provided. The association allows forwarding data frames including the MAC address as destination MAC address via the associated switch port. Related methods include receiving a data frame originating from a node. The data frame includes a MAC address of the originating note as source MAC address. The data frame is stored including the MAC address. The data frame is successfully sent towards a first switch port. In response to a failure of a first link towards the first switch port, the stored data frame is resent towards a seconds switch port that is different from the first switch port for triggering the association between the second switch port and the MAC address of the originating node.

Technique for network service availability

The invention relates to a methodin a packet forwarding devicein an Internet Protocol, IP, networkfor congestion control. The methodcomprises: receivingan IP packetoriginating from a first network nodeand addressed to a second network node; determininga congestion status on a network path from the second network nodeto the first network node; and entering, for a congestion status indicating congestion, congestion information into a headerof the IP packet, the congestion status congestion information notifying the second network nodeabout congestion present on the network path. The invention also relates to a packet forwarding device, a computer programand computer program product

Methods and devices in an IP network for congestion control

The present disclosure relates to a network protection scheme. In one embodiment, there provides a method for network protection, including the steps of: detecting a switch indicator in a network; setting a rate limit of storm protection, which is of a first value, as a second value, the second value being higher than the first value; and performing a flush operation of a Forwarding DataBase FDB.
