Link connection status between step 501, the detection of first link and second link; When link connects normal; Be that N the passage of N passage and second interface of first interface of self is when being link up state; Begin to start follow-up,, carry out the handling process that the passage of self first interface is adjusted in proper order with reference to the passage order of second interface of second link.
Step 502, first link are to the second link sending order notification message; When this order notification message is used to indicate the follow-up transmission test packet of second link according to specified order, this specified order is the order to N passage of second interface of second link.
This specified order can be provided with according to actual needs; For example; Adjustment for the ease of follow-up self passage order; This specified order can be an example to comprise 4 passages for the passage order of N passage of second interface, and this specified order is passage 1, the passage 2 from second interface, the order of passage 3 to passage 4.
Preferable; This order notification message can also be used to indicate the time interval when second link is follow-up to send test packet through this N passage; So that the test packet through this N passage sends respectively can arrive first link according to the sequencing that sends more accurately.
Concrete, first link can send to second link through a passage of first interface should the order notification message.
Step 503, second link are therefrom known this specified order after receiving this order notification message of first link transmission.
Preferable, in the time of can also from this order notification message, knowing the time interval of sending test packet.
In the above-mentioned steps 501-step 503; Be this specified order to be set, and notify second link, among other embodiment by first link; Also can this specified order be set by second link; Notify first link, and after receiving the correspondence response that first link returns, start the forwarding step of follow-up test message.
Among other embodiment; Can also adopt the mode of making an appointment between first link and second link; This identical specified order of static configuration separately then before carrying out the treatment step that further channel adjusts in proper order, no longer need be carried out above-mentioned steps 501-503.
Step 504, second link be according to this specified order, through N passage of second interface, is taken up in order of priority and sends test packet to first link, as according to the order from passage 1, passage 2, passage 3 to passage 4.Specifically can send a test packet, send N test packet altogether from each passage.In the embodiment of the invention,,, can be the test packet of arbitrary content so need the content of this test packet not limited because first link need not resolved the content of this test packet.
Preferable, can be to first link through this N passage, according to this time interval, be taken up in order of priority the transmission test packet.
Step 505, first link are taken up in order of priority to receive test packet through N passage of first interface, and definitely are taken up in order of priority the order that receives test packet from N passage of first interface.
For example, be example with interface annexation shown in Figure 4, first link from the order that 4 passages of first interface receive test packet does, from the order of the passage 4 of first interface, passage 3, passage 2 to passage 1.
Step 506, first link receive the order of test packet based on above-mentioned specified order with from N passage of first interface, confirm the corresponding annexation of N passage with N the passage of second interface of first interface.
For example, be example with interface annexation shown in Figure 4, this definite correspondence annexation is as shown in table 1:
Table 1
| Second interface of second link | First interface of first link |
| Passage 1 | Passage 4 |
| Passage 2 | Passage 3 |
| Passage 3 | Passage 2 |
| Passage 4 | Passage 1 |
Can know that from table 1 passage 4 of first interface, passage 3, passage 2 and passage 1 are respectively with passage 1, passage 2, passage 3 and 4 corresponding connections of passage of first interface.
First link is after the corresponding annexation of a plurality of passages of determining self first interface and a plurality of passages of second interface of second link; Follow-up promptly can be according to this correspondence annexation; Passage order according to a plurality of passages of second link; Message to a plurality of passages through first interface receive is recombinated, and obtains correct message, and detailed message receives and the processing procedure of reorganization no longer is described in detail at this.
Further, in the time need carrying out the message reorganization in proper order, need the passage sequence consensus of a plurality of passages of a plurality of passages and second interface of adjustment self first interface according to the passage of a plurality of passages of self first interface, specific as follows:
Whether step 507, first link be based on this correspondence annexation, confirms the passage order of N passage of self first interface, with the passage sequence consensus of N passage of second interface of second link; If it is inconsistent; Get into step 508,, represent the passage sequence consensus of first interface and second interface if consistent; Then cancel the handling process that passage is adjusted in proper order, directly get into step 509.
Wherein, every pair of passage that first interface and second interface are corresponding interconnected, the ordinal position in N the passage under separately are all consistent, expression passage sequence consensus, otherwise expression passage order is inconsistent.
So; Based on the mode of above-mentioned employing channel position as gap marker; Every pair of passage that first interface and second interface are corresponding interconnected only needs this gap marker to passage consistent, representes that promptly this is consistent to the ordinal position of passage in N the passage that belongs to separately.
If step 508 is inconsistent; Between follow-up first link and second link; Can pass through interconnected first interface and the effective message transmission of second interface; First link is according to above-mentioned corresponding annexation, adjusts the passage sequence consensus of N passage of N passage and second interface of first interface.
Concrete, can by the CPU of first link through PCI (Peripheral Component Interconnection, peripheral element extension interface)/PCIE (
PCI-Express) interface, dispose the configuration register relevant in proper order with the passage of first interface, the passage of first interface is adjusted into the passage sequence consensus with N passage of second interface in proper order.
Step 509, first link are behind the passage sequence consensus of the passage order of confirming or adjusting first interface and second interface; Can through with the interacting message of second link; The notice opposite end has been confirmed the passage sequence consensus with the opposite end interconnecting interface, specifically can be following:
First link is used to notify second link passage order consistent to the consistent notification message of the second link sending order.For example, the passage 1 from adjusted first interface sends this sequence consensus notification message.
Second link can return corresponding sequence consensus push-notification-answer to first link after receiving this sequence consensus notification message, represent self to have known that the passage order is consistent.For example, the passage 1 from second interface sends this sequence consensus push-notification-answer.
First link and second link be through above-mentioned handling process shown in Figure 5, adjust the passage sequence consensus of first interface and second an interface N separately passage after, promptly can carry out the transmission of message through first interface and second interface.
