determining the service demand and the required bandwidth of the encrypted service bearing shared tunnel and the non-encrypted bearing exclusive tunnel in different time periods of the corresponding cycle duration according to the corresponding channel cycle duration occupied by the encrypted service bearing shared tunnel and the non-encrypted bearing exclusive tunnel;
determining the priority of each service in the corresponding time period of the corresponding channel cycle time according to the service demand and the required bandwidth of the corresponding encrypted service bearer shared tunnel and the non-encrypted bearer exclusive tunnel in different time periods of the corresponding cycle time;
and allocating resources to the service according to the priority, wherein the method comprises the following steps:
acquiring the computing capacity and the required bandwidth of the user equipment from the equipment identifier, and respectively setting required factors according to the computing capacity and the required bandwidth;
the demand factors are respectively accumulated with the products of the corresponding computing power and the demand bandwidth to obtain weighted demand factors, and a maximum and minimum fair constraint distribution strategy is determined;
and distributing the message data to the service channels of the corresponding optimal paths according to the maximum and minimum fair constraint distribution strategy and the priority sequence of the services in sequence.
2. The SD-WAN based Service Level Agreement (SLA) traffic-carrying method of claim 1, further comprising: acquiring bandwidth use information and load bearing information of a current service channel, and adjusting the distribution bandwidth of the service channel according to the bandwidth use information, the load bearing information and the priority.
