Overview ¶
Package core provides an entry point to use V2Ray core functionalities.
V2Ray makes it possible to accept incoming network connections with certain protocol, process the data, and send them through another connection with the same or a difference protocol on demand.
It may be configured to work with multiple protocols at the same time, and uses the internal router to tunnel through different inbound and outbound connections.
