This method comprise DSL multi-thread to synchronization loss under the pattern detection and solve two aspects:
Wherein, multi-thread detection method to synchronization loss is as follows:
Each physical port of automatic regular polling dsl device is checked the current Link State (as: Handshake, Training, Linkup etc.) of each physical port, if Link State becomes other states by normal link setup (Linkup), then notes the time at that time.When having part and whole line, several line centerings of finding binding work then can not be judged as this group line to out of joint to still reaching the link setup state after surpassing the time threshold of setting.
Wherein, multi-thread processing method to synchronization loss is as follows:
Find by practice, to belonging to this line under the pattern corresponding port of group is carried out reset operation one time, can rebulid synchronously multi-thread.
When on a dsl device, multi-thread to pattern simultaneously and when depositing, being needed to distinguish and treat two kinds of ports under the pattern, only to the multi-thread operation of port under the pattern being carried out " involving in a criminal case " formula with single line.
Fig. 3 is a multi-thread flow chart to dsl device detection and processing method according to another embodiment of the present invention.With the SHDSL4 ray mode is example, and line is illustrated a synchronisation loss detection and processing method.
Establishment is used for writing down the array aOpState[of port Link State].Establishment is used for writing down the array deadChkTimestamp[that the port status transformation period stabs].Regularly all user ports are carried out poll.
The detection procedure that each poll is carried out is as follows:
Step S302 checks each port successively.If check out last port, then the epicycle flow process finishes.Otherwise carry out following step.
Step S304, with next port as working as front port.
Step S306 is if the controlled state of working as front port is then carried out next step inspection (step S308) to this port for enabling; If its controlled state then jumps to the inspection that step S302 carries out next port for forbidding.
Step S308, inquiry is worked as the line of front port to pattern, if 2 lines are to then entering the right processing branch (step S310) of 2 lines; If 4 lines are right, then jump to the right processing branch (step S322) of 4 lines.
Step S310-S316 is if the Link State of this port is initial state or link setup state, then with the correspondent time zero clearing and jump to step S302 and continue to check next port.If the current time stamp is 0, then writes down the current time and jump to step S302 continuation inspection next port.Otherwise carry out next procedure.
Step S318-S320 calculates the difference between current time and the timestamp, if less than preset threshold, then jumps to step S302 and continues to check next port.If greater than preset threshold, this port that then resets, and logging timestamp.Jump to step S302 then and continue to check next port.
Step S322, check when front port whether be a pair of line to first port in the port, if the step below then continuing, if not, then jump to step S302 and carry out next port.(a pair of port focuses in once checking, therefore will avoid rechecking to the port in the back in the paired port)
Step S324-S330 is if the Link State of two pairs of ports all is initial state or link setup state, then with the correspondent time zero clearing and jump to step S302 and continue to check next port.If the current time stamp all is 0, then writes down the current time and jump to step S302 continuation inspection next port.Otherwise carry out next procedure.
Step S332-S334 calculates the difference between two port current time and the timestamp, continues to check next port if two differences, then jump to step S302 all less than preset threshold.If greater than preset threshold, this link that then resets, and logging timestamp to port.Jump to step S302 then and continue to check next port.
To 2 lines to 4 lines to pattern, different time thresholds can be set.
