Background
Broadcast and multicast are modes of one-to-many communication, which can save businesses on the network bandwidth and reduce network load through point-to-multipoint efficient data transmission.
In the unicast mode, the initiating server sends data to N servers separately. If the multicast mode, the server sends the same data to N servers in once, which reduces the server resource consumption and also the bandwidth resource of the backbone network.
Multicast: Tencent Cloud supports multicast on the VPC dimension.
Broadcast: Tencent Cloud supports broadcast on the subnet dimension.

The trail period of VPC has
Multicast and broadcast are available in Beijing, Shanghai, Guangzhou, Chengdu, Chongqing, Nanjing, Hong Kong, Singapore, Seoul, Tokyo, Bangkok, Silicon Valley, Virginia and Frankfurt.

Broadcast services or market data of the financial industry. For example, after obtaining stock prices and other real-time data, brokers can broadcast stock data to multiple clients in real time, effectively reducing network load.
For the game industry, broadcast and multicast are mainly used for heartbeat holding between multiple servers.
