Specific embodiment
Below in conjunction with attached drawing of the invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention.
A kind of disclosed method and device that RDI is realized based on chip, realizes RDI flag bit by chip
Setting and removing, reduce the burden of CPU, improve Message processing efficiency.
As shown in Figure 1, a kind of method that RDI is realized based on chip, including
CCM message is received, and judges whether the CCM message has RDI flag bit, and is indicated in CCM message with RDI
The state of chip is updated to there are failures when position；
Specifically, CCM message is used to detect the connectivity of link, in 802.1ag, by periodically sending CCM report
Text detects the connectivity of link, if continuous 3 CCM message losss, then it is assumed that other side is unreachable, i.e., there are failures for link.Such as
Shown in Fig. 2, the format of CCM message a comprising tag field, the tag field have 8 bits, wherein RDI mark
Position is in the 8th bit of tag field, and when implementation, during failure continues, RDI flag bit is set to 1 by chip, described
Chip is asic chip or fpga chip or NP chip etc..
When chip receives CCM message, first determine whether it has RDI flag bit, if it exists RDI flag bit, then
Show that there are failures, at this point, further the state of more new chip is that there are failures.When it is implemented, being equipped with shaped like chips in chip
State marker (PresentRDI), is used for the state of identification chip, can be identified by the way that the value of chip status marker is arranged
The state of chip.
Specifically, local fault register (LocalFailVector) is equipped in chip, local detection enables register
(LocalCheckEnableVector), enabled register is detected in far-end fault register (RemoteFailVector) and distal end
(RemoteCheckEnableVector).Wherein, local fault register is used for minute book earth fault reason comprising multiple
Bit, each bit can be used for identifying local failure cause, and the MEP id field that CCM message is modified in such as distal end is repaired
It is changed to the grade not being expected to；Local detection enables register for memorization COMS clip local failure cause to be detected, packet
The bit quantity contained is identical as the bit quantity that local fault register is included, and corresponds；Far-end fault deposit
Device is modified CCM time interval or is stopped for recording the CCM message and far-end fault reason that receive and have RDI flag bit, such as distal end
Only send CCM message etc.；Distal end detects enabled register and is used for memorization COMS clip far-end fault reason to be detected, it includes
Bit quantity is identical as the bit quantity that far-end fault register is included, and corresponds.
When it is implemented, the value of chip status flag bit can be calculated by following expression:
PresentRDI=[(LocalCheckEnableVector&LocalFailVector)] |
[(RemoteCheckEnableVector&RemoteFailVector)]
Further, in the state of chip there are when failure, sending to distal end to chip periodicity has RDI flag bit
CCM message.
Specifically, when the status display of chip be there are when failure, chip by behind the mark position RDI 1 in CCM message,
Periodically CCM message is sent to distal end.After fault recovery, the RDI flag bit in CCM message is removed by chip.Pass through
Chip replaces upper layer software (applications) to carry out the setting and removing of RDI flag bit, effectively reduces the occupancy of CPU.
As shown in figure 3, a kind of device that RDI is realized based on chip, including
Enter direction message processing module (MPM), for receiving message and judging whether the CCM message has RDI flag bit, and
The state of chip is updated to there are failures when CCM message has RDI flag bit；
Outgoing packet processing module is periodically to send and have more to distal end there are when failure for the state in chip
There is the CCM message of RDI flag bit.
Specifically, entering direction message processing module (MPM) includes message receiving module, judgment module and state update module,
In, CCM message is sent in judgment module by message receiving module for receiving CCM message；Judgment module is for judging
Whether CCM message has RDI flag bit；State update module is used for the state of chip when CCM message has RDI flag bit
It is updated to that there are failures.
Direction processing module includes flag bit setup module and message sending module out, wherein flag bit setup module is used
It is that there are by the mark position RDI in CCM message be 1 when failure in the state in chip；Message sending module is for periodically
CCM message with RDI flag bit is sent to distal end.
When implementation, the state of chip identifies core by the value of chip status marker (PresentRDI) in setting chip
The state of piece, when implementation, the value of the settable chip status marker of state update module such as sets the value of chip status flag bit
When being set to 1, indicate that there are failures；When setting 0 for the value of chip status flag bit, indicate that failure is not present.
Further, entering direction processing module further includes local fault register (LocalFailVector), local detection
Enabled register (LocalCheckEnableVector), far-end fault register (RemoteFailVector) and distal end are detected
Enabled register (RemoteCheckEnableVector).Wherein, local fault register is used for minute book earth fault reason,
It includes multiple bits, and each bit can be used for identifying local failure cause (as the MEP ID word of CCM message is modified in distal end
Section,Local terminal thinks that the value is incorrect)；Local detection enables register and is used for memorization COMS clip local failure cause to be detected,
It includes bit quantity it is identical as the bit quantity that local fault register is included, and correspond；Far-end fault
Register receives CCM message and far-end fault reason with RDI flag bit for recording, as between the modification CCM time of distal end
Every or stop sending CCM message etc.；Distal end detects enabled register and is used for memorization COMS clip far-end fault reason to be detected,
The bit quantity for including is identical as the bit quantity that far-end fault register is included, and corresponds.
When it is implemented, state update module passes through the value of following expression computing chip state flag bit:
PresentRDI=[(LocalCheckEnableVector&LocalFailVector)] |
[(RemoteCheckEnableVector&RemoteFailVector)]
The present invention is arranged by chip and removes RDI mark, without reporting CPU to be arranged by upper layer software (applications) and removing RDI
Mark, alleviates the burden of CPU, improves Message processing efficiency.
