Value, WLAN link packet drop rates, TCP retransmission rates, network delay and history network speed.Wherein, RSSI value can represent WLAN
Signal strength signal intensity, RSSI value shows that more greatly the signal strength signal intensity of WLAN is better；WLAN link packet drop rates are referred to by wireless office
During the net transmission data of domain, the data packet number lost in transmitting procedure accounts for the ratio of sent total data bag quantity；TCP is retransmitted
Rate referred in data transmission procedure, the ratio between the data transmitted again and total data；Network delay refers to data in net
The time used is transmitted in network；History network speed refers to network described in computer equipment in data transfer, request data with
Time difference between returned data, wherein, computer equipment calculate wireless lan signal score value when, the history network speed of acquisition
For history network speed maximum.According to pre-configured wireless lan signal scoring, can be to RSSI value, WLAN packet loss of link
Rate, TCP retransmission rates, network delay and history network speed are scored, and obtain RSSI score values, WLAN link packet drop rate score values, TCP weights
