The present disclosure relates to the technical field of wireless network communications, and provides a method, system and client for uploading an image, a network server and a computer storage medium. The method includes: a client determines an image to be uploaded, generates a unique image identifier corresponding to the image to be uploaded, and transmits an image detection request to a network server; the network server detects whether there is an image having the same image identifier in the network server according to the image identifier included in the image detection request, and returns a detection result to the client; when the detection result is that there is not an image having the same image identifier in the network server, the client uploads the image to be uploaded in the form of multi-part uploading to the network server; and after the image to be uploaded is uploaded successfully, the network server records the image identifier, and returns an upload success response to the client. The present disclosure avoids a repeated uploading of a same image, so that the upload rate is improved, a great deal of network traffic bandwidth is saved, and user experiences are improved.

Method, system and client for uploading image, network server and computer storage medium

Provided are a device unit, a node device, and a method and a system for automatically adjusting a tunnel bandwidth. The device unit includes: a client side element, configured to dynamically adjust The quantity of the first timeslots according to a bandwidth of a received data service before the received data service is mapped to an Optical Channel Data Unit (ODU) tunnel; a line side element, configured to configure, according to the quantity of the first timeslots adjusted by the client side element, The quantity of the second timeslots matched with the first timeslots; a tunnel managing element, configured to adjust, according to the quantity of the first timeslots and the quantity of the second timeslots, the quantity of unblocked ODU tunnels between the client side element and the line side element, wherein unblocked ODU tunnels after the adjustment carry the data service. When the bandwidth of the received data service increases or decreases, the device unit of the present disclosure flexibly controls usage of an ODU0 timeslot in an ODU of each stage, and does not need to use a complicated ODUflex frame format, thereby meeting the requirement of automatically adjusting the bandwidth without using ODUflex.
