Method and device for detecting network reliability

A detection apparatus, comprising a processor to:

• obtain a first transmission on a network comprising an indication of a first quantity of data packets, the indication of the first quantity of data packets comprised in a first packet sent by a first network node to a second network node, wherein the first packet is a special packet sent by the first network node to the second network node on the network to cause the second network node to send an access request;
• obtain a second transmission on the network comprising first feedback information sent by the second network node, wherein the first feedback information comprises an indication of a second quantity of data packets, the indication of the second quantity of data packets comprised in the first packet received by the second network node;
• calculate communication service availability (CSA) of each of a plurality of network channels from the first network node to the second network node based on the indication of the first quantity and the indication of the second quantity;
• select a target network channel from the plurality of network channels based on the CSA of each network channel;
• and
• transmit data from the first network node to the second network node using the target network channel.

A network element, comprising a processor to:

• obtain a first transmission on a network comprising an indication of a first quantity of data packets, the indication of the first quantity of data packets comprised in a first packet sent by a first module to a second module, wherein the first packet is a special packet sent by the first module to the second module to cause the second module to send an access request;
• obtain a second transmission on the network comprising first feedback information sent by the second module, wherein the first feedback information comprises an indication of a second quantity of data packets, the indication of the second quantity of data packets comprised in the first packet received by the second module;
• and
• calculate communication service availability (CSA) of each of a plurality of network channels from the first module to the second module based on the indication of the first quantity and the indication of the second quantity;
• select a target network channel from the plurality of network channels based on the CSA of each network channel;
• and
• configure the target network channel to transmit data from the first module to the second module.
