Abstract
A packet loss notification in a video transmission may be performed by a network device. The network device may receive a first video packet sent from a first client to a second client. The network device may determine that the first video packet has been lost. The network device may determine a video packet receiving port number of the first client. The network device may receive a second video packet sent from the second client to the first client. The network device may determine that the second video packet includes a destination port number that matches a video packet receiving port number of the first client. The network device may modify the second video packet by adding packet loss information indicating that the first video packet has been lost. The network device may send the modified second video packet to the first client.
