Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The technical scheme provided by the embodiment of the invention can be applied to a Flexe network architecture shown in figure 1. The network architecture includes a first network device and a second network device.
The network device (e.g., the first network node, the second network node, etc.) is a device having a data transceiving function in the flexible ethernet, such as a router, a switch, etc. supporting the flexible ethernet function. The first network node and the second network node have at least one ethernet physical link therebetween.
Fig. 2 is an exemplary diagram of first node and second node flexible ethernet interface connections and second node flexible ethernet group bindable interface collection information. Each node comprises 16 flexible ethernet interfaces, and is connected through 4 of the interfaces.
Preferably, 4 interfaces of the second node connected to the first node are all bound to the same flexible ethernet group. However, the second node cannot acquire the capability information that the 4 interfaces connected with the first node and the second node support the binding to the same flexible ethernet group, which affects the flexible ethernet group link creation, resulting in lower flexible ethernet link management efficiency.
In order to improve the efficiency of flexible ethernet link management, embodiments of the present application provide a flexible ethernet link management method, where a network node may obtain information of all neighboring nodes to create a flexible ethernet group. An embodiment of the method of the present application is described in detail below with reference to fig. 3.
Fig. 3 is a flowchart illustrating a flexible ethernet link management method according to an embodiment of the present application. The flexible ethernet network comprises at least two network nodes connected by at least one flexible ethernet interface.
The method of fig. 3 is as follows:
s1, flexible Ethernet interface numbers of the first node and the second node, wherein the numbers are unique under the nodes.
S2, the first node and the second node acquire the number binding information of all Flexe interfaces of the node, wherein the number binding information comprises: the number of the Flexe interface supports a Flexe interface number collection bound to the same flexible Ethernet group together with the Flexe interface.
S3, the first node selects a Flexe interface connected with the second node, encapsulates the serial number binding information of the Flexe interface in a Flexe overhead frame, and sends the frame to the second node.
S4, after all Flexe interfaces connected with the first node by the second node acquire the number binding information of the Flexe interface of the first node, acquiring link attribute information of the second node and the first node, wherein the link attribute information comprises: the number pair of Flexe interfaces of the second node is connected with the first node; the second node may be operative to create a FlexE interface number set of flexible ethernet group links with the first node.
The process is applicable to both the first node and the second node, that is, the first node may also obtain the link attribute information of the second node according to the process.
Preferably, the network node may obtain the identification information of the neighboring node, such as the IP address of the node, through the management or control communication channel, and complete the flexible ethernet group creation in cooperation with the link attribute information.
Fig. 4 to 8 are detailed descriptions of the implementation of the flow illustrated in fig. 3.
Step S1 is as shown in fig. 4, numbering the 16 FlexE interfaces 1-16 for the first node and the second node, respectively, and connecting the first node interfaces 5, 6, 7, 8 to the second node interfaces 1, 2, 3, 4, respectively. The first node interfaces 4, 5 may be bound to the same flexible ethernet group, and the interfaces 6, 7, 8 may be bound to the same flexible ethernet group; the second node interfaces 1, 2, 3, 4 may be bound to the same flexible ethernet group.
It should be understood that the number of the network node FlexE interfaces 16 is only one implementation scenario of the embodiment of the present application, and the number of the network node FlexE interfaces may be determined according to practical situations, and the embodiment of the present application is not limited herein.
Preferably, in step S2, the first node and the second node are connected as an example:
the first node interface number and the interface number collection supporting the binding of the first node interface and the interface to the same flexible Ethernet group are shown in table 1;
TABLE 1 first node interface number set
| Interface numbering | 5 | 6 | 7 | 8 |
| Binary bitmap | 0b11000 | 0b11100000 | 0b11100000 | 0b11100000 |
| Decimal bitmap | 24 | 224 | 224 | 224 |
The second node interface number and the collection of interface numbers supporting binding to the same flexible ethernet group with this interface are shown in table 2. Wherein the interface number set information is expressed in a bitmap manner.
TABLE 2 second node interface number set
| Interface numbering | 1 | 2 | 3 | 4 |
| Binary bitmap | 0b1111 | 0b1111 | 0b1111 | 0b1111 |
| |
15 | 15 | 15 | 15 |
Taking the first node interface 5 as an example, if the interface 5 supports binding to the same flexible ethernet group as the interface 4, the corresponding number set of the interface 5 is 0b11000, that is, bit 3 and bit 4 are 1, and the other bits are 0, it is assumed here that the starting bit from the right is bit 0.
Preferably, step S3 is as shown in fig. 5 and 6, and fig. 5 and 6 will be described below, respectively.
Fig. 5 is an illustration of the format in which the information is carried using the FlexE overhead frame spare bits. The FlexE overhead frame consists of 8 66-bit overhead blocks, and a sequence of 32 overhead frames constitutes 1 overhead multiframe. The second 66-bit block bits 17-63 and the third 66-bit block bits 35-47 of the overhead frame are reserved bits. And when the number of the first node interfaces is not more than 512, carrying the number binding information by using the second 66-bit block spare bits 17 to 25 of the overhead frame, carrying the interface number collection information by using the second 66-bit block spare bits 26 to 40 of the 32 overhead frames of the overhead multiframe, and sending the interface number collection information to the second node.
It should be understood that the format of the FlexE overhead frame spare bits for carrying the information is only one implementation manner of the embodiment of the present application, and other reserved bits may also be used for carrying the information, or more or fewer reserved bits may be used for carrying the information when the maximum number of interfaces supported by a node is different, which is not limited herein.
Fig. 6 is an illustration of the format of the management channel provided by the FlexE interface to carry the information. The LLDP protocol IEEE802.1AB may be carried in the management channel for inter-interface connectivity verification. As shown in fig. 6, OIF OUI is added to the LLDP TLV extension and a new subtype 4 is introduced, identifying the subsequent bytes for carrying the information. The number binding information and the interface number set information occupy 2 bytes and 64 bytes respectively, are carried by LLDP TLV extension, and are sent to the second node by the first node.
It should be understood that the format in which the FlexE management channel carries the LLDP to carry the information is only one implementation manner of the embodiment of the present application, and the LLDP TLV extension may also carry the information in other formats, which is not limited herein.
Preferably, in step S4, taking the example that the first node and the second node are connected to each other, the pair of interface numbers of the first node and the second node, and the set of interface numbers that the first node can use to create the flexible ethernet group link with the second node are shown in table 3;
TABLE 3 interface number pairs for first node and second node
| Interface number pair | 5-1 | 6-2 | 7-3 | 8-4 |
| Binary bitmap | 0b1000 | 0b11100000 | 0b11100000 | 0b11100000 |
| |
8 | 224 | 224 | 224 |
The second node and the first node interface number pair, and the second node can be used to create a flexible ethernet group link with the first node, and the set of interface numbers comprising the port interface of the second node is shown in table 4. Wherein the interface number set information is expressed in a bitmap manner.
TABLE 4 second node and first node interface number pairs
| Interface number pair | 1-5 | 2-6 | 3-7 | 4-8 |
| Binary bitmap | 0b1 | 0b1110 | 0b1110 | 0b1110 |
| |
1 | 14 | 14 | 14 |
Preferably, taking the second node interface 2 as an example, if the interface is connected to the second node interface 6, the interface number pair is 2-6; the second node interface 2 supports binding to the same flexible ethernet group as interfaces 1, 3, 4, as seen in step 320, the collection of interface numbers is 0b 1111. In the connected interfaces 5, 6, 7, 8 corresponding to the first node, the interface 5 does not support binding to the same flexible ethernet group as the interfaces 6, 7, 8, and the number pairs 1-5 cannot participate in binding the number pairs 2-6 to the same flexible ethernet group link. Thus, interface pair 2-6 corresponds to a set of numbers 0b1110 that can create a flexible ethernet group link, i.e., bit 1, bit 2, and bit 3 are 1, and the other bits are 0, assuming that the starting bit from the right is bit 0.
It should be understood that the collections described in step S2 and step S4 are expressed by a bitmap, which is only one implementation manner of the embodiment of the present application, and other manners of expressing the collection information may also be adopted, and the embodiment of the present application is not limited herein.
