Background technology
In IEEE 802.3ba standard, propose the ethernet standard that the network equipment adopts 40G/100G interfacing.
In 40G/100G interfacing, between two links connected by an interface (such as, between chip and chip, between board and board, and between equipment and equipment), what transfer of data adopted is multichannel concurrent transmission technology, and namely an interface comprises multiple passage, multiple passage of respective interface and multiple passages of opposite end interconnecting interface can be used between two links to transmit data, to improve the transmission rate of data simultaneously.
Such as, at 40G PMA (Physical Medium Attachment, physical medium accesses) in layer, XLAUI (40 Gigabit Attachment Unit Interface, the 40Gbps access unit interface) interfaces interconnect comprising 4 passages is used between two links; In 100G PMA layer, between two links, use CAUI (100 Gigabit Attachment Unit Interface, the 100Gbps access unit interface) interfaces interconnect comprising 10 passages; At 40G PMD (Physical Media Dependent, physical medium is correlated with) in layer, XLPPI (40 Gigabit parallel physical interface, the 40Gbps concurrent physical interface) interfaces interconnect comprising 4 passages is used between two links; In 100G pmd layer, between two links, use CPPI (100 Gigabit parallel physical interface, the 100Gbps concurrent physical interface) interfaces interconnect comprising 10 passages.
40G interface and 100G interface use identical interfacing, and for 40G XLAUI interface, as shown in Figure 1, XLAUI interface may be used for connection two PMA sublayers, such as, between MAC chip-MAC chip, MAC chip-PHY chip interconnected.XLAUI interface uses 4 passages, and each passage respectively has two pairs of differential lines to be respectively used to the transmitting-receiving of data, and the message transmission rate of each passage is 10.3125Gb/s.
Between two links due to interface, it is the concurrent transmission being carried out message by multiple passage, so one of them link respectively by self multiple channel reception after message, need according to certain channel sequence (also referred to as interface line sequence) to by this multiple channel reception to message recombinate, to obtain complete correct message.Therefore, for ensureing the correct transmitting-receiving of message, by the channel sequence of two links of interface inter-link multiple passages of interface separately, needs are consistent, namely interface line sequence is consistent, or, recipient can know the corresponding annexation of multiple passage of the other side and the multiple passages of self, thus can according to the channel sequence of the other side, to by self multiple channel reception to message recombinate, otherwise although the link of interconnected both sides is link up (connection) states, but recipient is owing to cannot carry out the restructuring of message according to correctly channel sequence, just some the nonsensical messages received.
Channel sequence based on above-mentioned two interconnected links multiple passages of interface separately needs the requirement be consistent, in current 40G/100G Design Technique of Interface, must strictly will follow the constraint of specification at the beginning of design, carry out synchronize design according to the channel sequence of specification agreement completely.Once channel sequence design mistake appears in any one end in two links, then can cause the transmitting-receiving normally cannot carrying out message between two interconnected links.Namely when principle design, for each link, the correctness of the channel sequence design of multiple passages of interface must be ensured, and in PCB design, the difficulty no matter cabling designs has much, principle design also must be submitted to, thus causing the difficulty of Interface design to strengthen, complexity is higher.

In the method shown in above-mentioned Fig. 2 and Fig. 3, this appointment order can be make an appointment between the first link and the second link, or, also can be before transmission test packet, by information interaction between first link and the second link, carry out arranging.
Below in conjunction with the defining method of accompanying drawing to the corresponding annexation of the passage shown in above-mentioned Fig. 2 and Fig. 3, and the handling process of the channel sequence of further adjustment interface, be described in detail, wherein, the first interface of the first link and the second interface inter-link of the second link, and first interface and the second interface comprise N number of passage respectively, N be greater than 1 integer, first link is as the link needing the channel sequence adjusting interface, second link is as not needing the channel sequence adjusting interface, but using the link of the channel sequence of self as opposite end adjustment reference, for 4 passages in the present embodiment 1, Figure 4 shows that the interface connection diagram of the first link and the second link, as shown in Figure 5, specifically comprise following treatment step:
Step 501, the first link detect the link connection state between the second link, when link connects normal, namely when N number of passage of the first interface of self and N number of passage of the second interface are link up state, start to start follow-up, with reference to the channel sequence of the second interface of the second link, carry out the handling process of the channel sequence adjustment of self first interface.
Step 502, the first link are to the second link sending order notification message, when this order notification message is used to indicate the second link follow-up transmission test packet according to appointment order, this appointment order is the order of N number of passage of the second interface for the second link.
This appointment order can be arranged according to actual needs, such as, for the ease of the adjustment of follow-up own channels order, this appointment order can be the channel sequence of N number of passage of the second interface, to comprise 4 passages, this appointment order is the order from the passage 1 of the second interface, passage 2, passage 3 to passage 4.
Preferably, this order notification message can also be used to indicate the second link subsequently through time interval during this N number of passage transmission test packet, so that by the test packet that this N number of passage sends respectively, the first link can be arrived according to the sequencing sent more accurately.
Concrete, the first link can send this order notification message by of a first interface passage to the second link.
After step 503, the second link receive this order notification message of the first link transmission, therefrom know this appointment order.
Preferably, when can also know the time interval sending test packet from this order notification message.
In above-mentioned steps 501-step 503, that this appointment order is set by the first link, and notify the second link, in other embodiment, also this appointment order can be set by the second link, notify the first link, and after receiving the correspondence response that the first link returns, start the forwarding step of follow-up test message.
In other embodiment, the mode of making an appointment can also be adopted between first link and the second link, this appointment order that respective static configuration is identical, then, before the treatment step carrying out the adjustment of further channel order, no longer need to perform above-mentioned steps 501-503.
Step 504, the second link, according to this appointment order, by N number of passage of the second interface, are taken up in order of priority to the first link and are sent test packet, as according to the order from passage 1, passage 2, passage 3 to passage 4.Specifically can send a test packet from each passage, send N number of test packet altogether.In the embodiment of the present invention, because the first link does not need to resolve the content of this test packet, so do not need to limit the content of this test packet, can be the test packet of arbitrary content.
Preferably, can to the first link by this N number of passage, according to this time interval, be taken up in order of priority transmission test packet.
Step 505, the first link, by N number of passage of first interface, are taken up in order of priority and are received test packet, and determine to be taken up in order of priority from N number of passage of first interface the order receiving test packet.
Such as, for the interface annexation shown in Fig. 4, the order of the first link from 4 channel reception of first interface to test packet is, from the order of the passage 4 of first interface, passage 3, passage 2 to passage 1.
Step 506, the first link are based on above-mentioned appointment order, and the order from N number of channel reception of first interface to test packet, determine the corresponding annexation of N number of passage of first interface and N number of passage of the second interface.
Such as, for the interface annexation shown in Fig. 4, this corresponding annexation determined is as shown in table 1:
Table 1
| Second interface of the second link | The first interface of the first link |
| Passage 1 | Passage 4 |
| Passage 2 | Passage 3 |
| Passage 3 | Passage 2 |
| Passage 4 | Passage 1 |
As can be known from Table 1, the passage 4 of first interface, passage 3, passage 2 and passage 1, respectively with passage 1, passage 2, the passage 3 of first interface with passage 4 is corresponding connects.
First link is after the corresponding annexation of multiple passages of the second interface of the multiple passage with the second link of determining self first interface, follow-up namely can according to this corresponding annexation, according to the channel sequence of multiple passages of the second link, the message of the multiple channel reception by first interface is recombinated, obtain correct message, detailed message receives and the processing procedure of restructuring is no longer described in detail at this.
Further, when needing to carry out Packet reassembling according to the channel sequence of multiple passages of self first interface, need to adjust multiple passage of self first interface consistent, specific as follows with the channel sequence of multiple passages of the second interface:
Step 507, the first link are based on this corresponding annexation, determine the channel sequence of N number of passage of self first interface, whether consistent with the channel sequence of N number of passage of the second interface of the second link, if inconsistent, enter step 508, if unanimously, represent that first interface is consistent with the channel sequence of the second interface, then cancel the handling process of channel sequence adjustment, directly enter step 509.
Wherein, often pair of passage that first interface and the second interface are corresponding interconnected, the ordinal position in the N number of passage belonging to is separately all consistent, represents that channel sequence is consistent, otherwise, represent that channel sequence is inconsistent.
So, based on the mode of above-mentioned employing channel position as gap marker, often pair of passage that first interface and the second interface are corresponding interconnected, only needs this consistent to the gap marker of passage, namely represents that this is consistent to the ordinal position of passage in N number of passage of ownership separately.
If step 508 is inconsistent, in order between follow-up first link and the second link, interconnected first interface and the effective message transmission of the second interface can be passed through, first link is according to above-mentioned corresponding annexation, and adjustment N number of passage of first interface is consistent with the channel sequence of N number of passage of the second interface.
Concrete, can by the CPU of the first link by PCI (Peripheral Component Interconnection, peripheral element extension interface)/PCIE (
pCI-Express) interface, configure the configuration register relevant to the channel sequence of first interface, the channel sequence of first interface is adjusted to consistent with the channel sequence of N number of passage of the second interface.
Step 509, the first link determine or adjust the channel sequence of first interface consistent with the channel sequence of the second interface after, can by the interacting message with the second link, notice opposite end has confirmed consistent with the channel sequence of opposite end interconnecting interface, specifically can be as follows:
First link is to the consistent notification message of the second link sending order, consistent for notifying the second link channel sequence.Such as, this sequence consensus notification message is sent from the passage 1 of the first interface after adjustment.
Second link, after receiving this sequence consensus notification message, can return corresponding sequence consensus push-notification-answer to the first link, represent and self known that channel sequence is consistent.Such as, this sequence consensus push-notification-answer is sent from the passage 1 of the second interface.
First link and the second link, by handling process shown in above-mentioned Fig. 5, after adjustment first interface is consistent with the channel sequence of the second interface N number of passage separately, namely can carry out the transmission of message by first interface and the second interface.

Step 601, the first link N number of passage of first interface by being connected with the second interface of the second link, sends test packet respectively to the second link.
In the embodiment of the present invention, because the first link and the second link do not need to resolve the content of this test packet, so do not need to limit the content of this test packet, can be the test packet of arbitrary content.
Step 602, receive the second link by uniquely arranging the passage of outer winding in N number of passage of the second interface, the test packet returned, the ordinal position of the passage uniquely arranging outer winding in N number of passage of the second interface is for specifying ordinal position.
Step 603, adjustment receive the passage of the test packet that the second link returns, and the ordinal position in N number of passage of first interface is this appointment ordinal position.
Accordingly, the embodiment of the present invention 2 also provides a kind of method of adjustment of channel sequence of interface, is applied to the link not needing the channel sequence adjusting interface, as shown in Figure 7, comprises:
Step 701, the second link, by N number of passage of self the second interface, receive the test packet that the first link is sent respectively by N number of passage of the first interface be connected with the second interface.
Step 702, by uniquely arranging the passage of outer winding in N number of passage of the second interface, this test packet is returned to the first link, the ordinal position of passage in N number of passage of the second interface uniquely arranging outer winding is appointment ordinal position, receive the passage of this test packet that the second link returns for the first link adjustment, the ordinal position in N number of passage of first interface is for specifying ordinal position.
In the method shown in above-mentioned Fig. 6 and Fig. 7, this appointment ordinal position can be make an appointment between the first link and the second link, or, also can be before transmission test packet, by information interaction between first link and the second link, carry out arranging.
In the said method provided in the present embodiment 2, because this appointment ordinal position is that the first link and the second link had been arranged before sending test packet, so, first link is after receiving the test packet that the second link returned by the passage that uniquely arranges outer winding, namely can determine in N number of passage of first interface, receiving the passage that the second link returns test packet, is uniquely arrange in the N number of passage with the second interface that the passage of outer winding is corresponding to be connected.
So, specifically can adopt each passage of said method adjustment first interface one by one, the channel sequence position consistency of interface channel corresponding to the second interface, thus it is consistent with the channel sequence of the second interface to realize first interface; Also N number of passage of said method determination first interface can be adopted with after the corresponding annexation of N number of passage of the second interface, more unified adjustment first interface is consistent with the channel sequence of the second interface.
Be described in detail below in conjunction with the method for adjustment of accompanying drawing to the channel sequence of the interface shown in above-mentioned Fig. 6 and Fig. 7, wherein, the first interface of the first link and the second interface inter-link of the second link, and first interface and the second interface comprise N number of passage respectively, N be greater than 1 integer, first link is as the link needing the channel sequence adjusting interface, second link is as not needing the channel sequence adjusting interface, but using the link of the channel sequence of self as opposite end adjustment reference, still for 4 passages in the present embodiment 2, Figure 4 shows that the interface connection diagram of the first link and the second link, as shown in Figure 8, specifically comprise following treatment step:
Step 801, the first link detect the link connection state between the second link, when link connects normal, namely when N number of passage of the first interface of self and N number of passage of the second interface are link up state, start to start follow-up, with reference to the channel sequence of the second interface of the second link, carry out the handling process of the channel sequence adjustment of self first interface.
Step 802, the first link are to the second link sending order position informing message, this ordinal position notification message is used to indicate the second link and uniquely arranges in N number of passage of the second interface the outer winding of the passage being in appointment ordinal position, and this appointment ordinal position is the ordinal position corresponding with current sequence number, the initial value of current sequence number can be set to 1.
Such as, when current sequence number is i, i is more than or equal to 1 and is less than N, and the passage being in this appointment ordinal position in N number of passage of the second interface is passage i.
Step 803, the second link, after receiving this ordinal position notification message, are therefrom known this appointment ordinal position, and are arranged in N number of passage of the second interface, are in the outer winding of passage of this appointment ordinal position.
And return corresponding ordinal position push-notification-answer to the first link, notify that in N number of passage of the first link second interface, the passage being in this appointment ordinal position has been set to outer winding.
Step 804, the first link, after receiving the ordinal position push-notification-answer that the second link returns, by the N number of passage of first interface be connected with the second interface of the second link, send test packet respectively to the second link.
Step 805, the second link, by N number of passage of self the second interface, after receiving the test packet that the first link sent respectively by N number of passage of first interface, by the current passage uniquely arranging outer winding, return test packet to the first link.
Step 806, the first link receive the second link by the second interface in the passage of outer winding is uniquely set, after this test packet returned, determine the passage receiving this test packet that the second link returns in first interface, for with the second interface in be in the passage of this appointment ordinal position, the corresponding passage connected, namely determine in N number of passage of first interface, the passage connected corresponding to the passage being in this appointment ordinal position in the second interface.
Step 807, judge whether current sequence number is less than N-1, if be less than, enter step 808, if be not less than, enter step 809.
Step 808, current sequence number are less than N-1, represent and need the transmission continuing through test packet, determine in N number of passage of first interface, with the corresponding annexation of the next passage of the second interface, so, in this step, current sequence number is updated to former sequence number and adds 1, then return and enter above-mentioned steps 802.
Step 809, current sequence number are not less than N-1, represent by the transmission of test packet, determine N-1 passage in N number of passage of first interface, respectively with the corresponding annexation of N-1 passage of the second interface, so, namely can determine a remaining passage in first interface, with a passage remaining in the second interface, for correspondence connect.
Thus determine the corresponding annexation of N number of passage of first interface and N number of passage of the second interface.
