Abstract: The present disclosure discloses an information sending method, electronic device and non-transitory computer-readable storage medium. The information sending method includes: sending a live video stream to a first set of clients; receiving first information sent from the first set of clients; recording a timestamp of the first information; sending the first information to the first set of clients; generating a recorded video stream of the live video stream, in response to completion of the sending of the live video stream; synchronizing the timestamp of the first information with the recorded video stream to obtain a playback timeline of the first information; sending the recorded video stream to the second set of clients, and sending the first information according to the play timeline of the first information; receiving second information sent from the second set of clients; and sending the second information to the second set of clients.

Abstract: After obtaining a virtual machine migration message, a control node performs first network configuration on a virtual switch of a new virtual machine. After performing the first network configuration, the control node creates the new virtual machine, and performs second network configuration on a second virtual switch in a virtual network in which a to-be-migrated virtual machine is located. In the present application, before the new virtual machine is created, a network connection of the to-be-migrated virtual machine is maintained, and a part of network configuration for the new virtual machine is completed.

Abstract: A method for service function chaining across subnetworks includes receiving a packet at a virtual switch integration bridge from a first service function (SF) that is in a service function chain (SFC) and that is on a first subnetwork, determining a next SF in the SFC in a different subnetwork, and sending the received packet directly from the virtual switch integration bridge to the next SF.
