105th, according to the priority of each type of message under first message type, the priority of currently available link and pre-
If scheduling strategy, the message under each type of message under first message type is assigned on corresponding link, with by right
The link answered forwards messages to equipment of the core network.
Specifically, server obtains the first number of currently available link first, and first message type includes
Second number of type of message, the first number is compared with the second number, to judge whether the first number is more than or waits
In the second number.After determining that the first number is more than or equal to the second number, server has under first message type
The type of message for having limit priority starts, according to priority orders successively by under each type of message under first message type
Message is assigned on link corresponding with own priority, to forward messages to equipment of the core network by the corresponding link.
Further, after determining that the first number is less than the second number, server is chosen from currently available link
The minimum link of priority is as the first link, and then the type of message with limit priority is opened under first message type
Begin, be gradually assigned to the message under type of message under first message type according to priority orders corresponding with own priority
On link, to forward messages to equipment of the core network by corresponding link.A type of message correspondence one in the present embodiment
Currently available link.
Because now the first number is less than the second number, i.e., the number of currently available link is less than the number of type of message.
Server can not distribute an available link for type of message all under first message type, in order to ensure first message class
Message under type under remaining all type of messages can be forwarded, and server can use weighted round-robin scheduling（Weighted
Round Robin, abbreviation WRR）Algorithm, the of selection is assigned to by the message under remaining type of message under first message type
On one link, the message under remaining type of message is transmitted to by equipment of the core network by first link.
For example, in the case where the number of currently available link is less than the number of type of message, it is assumed that currently available
The number of link is L, and the number of type of message is X, wherein, L ＜ X.First from the currently available link of L bars, priority is chosen
Minimum L links are used as the first link.L-1 high-priority message type is corresponded respectively and is sent to high priority
Message under available link, remaining X-L+1 type of message is assigned on L links using WRR algorithms, passes through L links
Message under remaining type of message is transmitted to equipment of the core network.
The link scheduling method based on priority that the present embodiment is provided, receives and determines the type of message of each message,
Judge whether each type of message has corresponding forwarding rule, the type of message without forwarding rule is defined as into first disappears
Type is ceased, the priority and the priority of currently available link of each type of message under first message type is obtained, according to the
Priority, the priority of currently available link and the default scheduling strategy of each type of message under one type of message, by
Message under one type of message under each type of message is assigned on corresponding link, to be forwarded message by corresponding link
