Bandwidth adjustment and correction method, apparatus and device, and storage medium

An apparatus, comprising a processor and a memory storing a program which, when executed by the processor, causes the processor to carry out a bandwidth adjustment and correction method, comprising,

• adding a connection admission control (CAC) parameter to quality-of-service (QoS) parameters;
• acquiring an enabling state of a CAC of a preset path in response to an increase in a bandwidth of service of the preset path;
• acquiring a bandwidth carried by a tunnel layer where the preset path is presented in response to a state in which the CAC is enabled;
• determining a target route that matches the service of the preset path according to an adjusted bandwidth and a preset route policy of the preset path in response to an overrun in the bandwidth carried by the tunnel layer;
• and
• adjusting the preset path to the target route in response to a presence of the target route;
• and
• determining the target route that matches the service of the preset path according to the adjusted bandwidth and the preset route policy of the preset path in response to the overrun in the bandwidth carried by the tunnel layer comprises:
• determining as to whether the bandwidth carried by the tunnel layer is sufficient for the bandwidth adjustment by performing a recursive determination on a bandwidth of an operating pseudo wire and a bandwidth of a protection pseudo wire;
• adjusting the bandwidth of the operating pseudo wire via a previous command code for a previous adjustment of the bandwidth of the protection pseudo wire in case the bandwidth carried by the tunnel layer is sufficient for a current adjustment;
• and
• calculating the target route via new QoS parameters in case the bandwidth carried by the tunnel layer is insufficient for the current adjustment.

A non-transitory computer-readable storage medium, storing a computer program which, when executed by a processor, causes the processor to carry out a bandwidth adjustment and correction method, comprising,

• adding a connection admission control (CAC) parameter to quality-of-service (QOS) parameters;
• acquiring an enabling state of a CAC of a preset path in response to an increase in a bandwidth of service of the preset path;
• acquiring a bandwidth carried by a tunnel layer where the preset path is presented in response to a state in which the CAC is enabled;
• determining a target route that matches the service of the preset path according to an adjusted bandwidth and a preset route policy of the preset path in response to an overrun in the bandwidth carried by the tunnel layer;
• and
• adjusting the preset path to the target route in response to a presence of the target route;
• and
• determining the target route that matches the service of the preset path according to the adjusted bandwidth and the preset route policy of the preset path in response to the overrun in the bandwidth carried by the tunnel layer comprises:
