Method and system for controlling multiple auxiliary streams, control device, and node

A method for controlling multiple auxiliary streams, comprising:

• acquiring, by a first node from a control device, a first token required by a first auxiliary stream comprising a multiple auxiliary stream subset of the multiple auxiliary streams;
• acquiring, by the first node from the control device, a second token, the second token being a parent token to the first token;
• determining, by the first node, a type of the first token, the first token being a type of child token corresponding to an auxiliary stream;
• receiving, by the first node, a first indication message sent by the control device, the first indication message instructing the first node to send the first auxiliary stream;
• and
• sending, by the first node, the first auxiliary stream according to the determined type of the first token.

A control device comprising:

• a memory storing computer executable program codes;
• a communication interface;
• and
• a processor coupled to the memory and the communication interface, the program codes comprising instructions that when executed by the processor, cause the processor to:
• determine whether to allocate a token to at least one auxiliary stream of m auxiliary streams, the m auxiliary streams belonging to n nodes, the token being a type of child token corresponding to an auxiliary stream, the child token having a corresponding parent token, the corresponding parent token being a token type corresponding to a node, n≥1, m≥2, and m≥n;
• allocate the token to a first auxiliary stream, the first auxiliary stream comprising multiple auxiliary streams of the m auxiliary streams;
• allocate a second token to a first node of the n nodes, the second token being a parent token to the token;
• send the token and the second token to the first node;
• and
• send a first indication message to the first node, the first indication message instructing the first node to send the first auxiliary stream according to the token.
