摘要： An object of the present invention is to provide a communication system and a communication method that can avoid network congestion using a simple approach. The communication system of the present invention is characterized in that a time distribution server that transmits time information to terminals distributes a time different from the standard time for each terminal, and the terminal performs communication on the basis of the distributed time, and further characterized in that, for a time synchronizing packet transmitted from a time distribution server on the Internet to a terminal, a node or the like in the middle of the path performs transfer control or rewrites the packet, thereby causing the terminal to recognize a different time, and the terminal performs communication on the basis of the time.

摘要： The present disclosure aims to make it possible to transfer multicast packets at as high a rate as possible according to a state of a network, to perform high-quality and low-latency content distribution, and to perform stable multicast distribution on a network that is less likely to ensure a fixed available band such as a best-effort or wireless network.
The present disclosure is a content distribution system for converting part of communication for distribution into multicast communication, in which
a transmission-side edge server (UC/MC) applies Forward Error Correction to a multicast packet and transmits the multicast packet, a reception-side edge server (MC/UC) notifies the transmission-side edge server of information of packet loss of the received multicast packet, and
the transmission-side edge server (UC/MC) changes a transfer rate of a multicast packet to be transmitted based on the notified information of packet loss.
