Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The prior art also provides a client (client) bearer management control message using FlexE. The traffic of one client has a bandwidth of at least 5Gbps. For this approach, the bandwidth of the client is 5Gbps. If a client with a bandwidth of 5Gbps is used as DCN, it is very wasteful. If the business of the client is followed, the business of the client is also related to the configuration of the client. Traffic may have intermediate cross-point processing and if not specifically processed, these points would have to additionally establish channels. If the configuration of clients changes, network topology changes and routing changes are caused, and considerable complexity is brought to the establishment and operation of the management network.
In order to solve the problems in the prior art, the embodiment of the invention provides a message processing method.
Referring to fig. 1, fig. 1 is a flowchart of a message processing method provided by an embodiment of the present invention, which is applied to FlexE devices, as shown in fig. 1, and includes the following steps:
step 101, determining a bandwidth required for transmitting a management code block, where the management code block is used for carrying a management control message.
In the embodiment of the invention, a new code block, namely a management code block, is defined and is provided with a bearing management control message.
As shown in table 1, each field included in the management code block is included.
TABLE 1
0 1 2-9 10-11 12-33 34-37 38-53 54-61 62-65
1 0 0x4B Resv Payload M Payload Seq CRC4
The fields are defined as follows:
code block type field 0x4B:8 bits for indicating the code block type. For example, the code block is indicated as being of the 0 code type.
Resv:2bit, reserved field, default to 0x00.
Payload field Payload:32 bits for carrying management control messages.
M field: 4bit, default to 0x02, support settings for representing SPN (Slicing Packet Network, slice packet network) in-band management channels.
Sequence number field Seq:4bit, the sending sequence number of the identification management control message is used for message recovery of the receiving end.
Check field CRC4:4 bits, checking 60 bits in total for 0-7 bytes (excluding CRC4 and synchronization header) of an SPN operation maintenance management (OAM) code block; all operation and maintenance administration (OAM) blocks are only valid if the CRC check is correct. Algorithm polynomial: x is x 4 +x+1, with an initial value of 0. This CRC check may also be unnecessary because the ethernet message contains FCS (Frame Check Sequence ).
In an embodiment of the present invention, the bandwidth required for transmitting the management code block may be determined by:
(1) The bandwidth reserved for FlexE Instance is taken as the bandwidth required for transmitting the management code block. That is, in this manner, a certain bandwidth is reserved for the entire FlexE Instance (e.g., 100GBASE-R whole that is not split), and there is no need to exclusively let a client reserve bandwidth.
(2) And acquiring the number of sub-interfaces included in the FlexE Instance and the reserved bandwidth of each sub-interface, and determining the total reserved bandwidth of all the sub-interfaces according to the number of the sub-interfaces and the reserved bandwidth of each sub-interface. And then, determining the bandwidth required by transmitting the management code block according to the total bandwidth of the FlexE Instance and the total reserved bandwidth of all the sub-interfaces.
Specifically, bandwidth is reserved for the management code block according to a target interval, wherein the target interval is the quotient of the total bandwidth and the total reserved bandwidth of all sub-interfaces.
For example, using each slot of FlexE as a sub-interface, one Instance (e.g., 100 GBASE-R) up to 20 sub-interfaces is used to construct the DCN, which becomes the next hop for the route. Taking a fixed reservation of 1Mbps bandwidth for one slot as an example, how much bandwidth is needed for each sub-interface, then the 1Mbps bandwidth of how many slots is occupied. An Instance of 100Gbps has 20Mbps bandwidth available. Under this client configuration, 1Mbps bandwidth is subtracted per 5Gbps bandwidth.
And 102, replacing an IDLE code block in the original data stream by using the management code block according to the bandwidth to form a DCN message.
The bandwidth determined in step 101 corresponds to the period of insertion of the management code block into the original data stream. Therefore, according to the bandwidth, the IDLE code block to be replaced can be determined, and the IDLE code block is replaced by the management code block, so that the DCN message is formed.
Step 103, sending the DCN message.
In the embodiment of the invention, the required bandwidth is set for the management code block carrying the management control message, and the management code stream is utilized to replace the IDLE code block in the original data stream to form the DCN message. Therefore, compared with the prior art, by utilizing the scheme of the embodiment of the invention, enough bandwidth bearing management control messages can be provided when network management is carried out in the FlexE.
Meanwhile, compared with client bearing of the follow-up service, the embodiment of the invention does not depend on the configuration of clients, does not need to consider complex scenes such as cross connection and the like, and only needs to reserve part of bandwidth.
At the beginning of powering up the FlexE device, in order to implement management of the FlexE device, the entire FlexE Instance is configured as a sub-interface for ethernet.
In practical application, at the beginning of powering up the FlexE device, the network has no FlexE client configuration, no service, and a large number of IDLE code blocks in the time slot. If the network is to be managed, the whole FlexE Instance (for example, the whole 100GBASE-R which is not segmented) is used as a subinterface according to a default mode, and the network is managed by performing conventional configuration IP according to a general ethernet.
Optionally, in the embodiment of the present invention, in order to reduce the influence on the DCN network, the DCN packet in the IP format sent by the DCN network may be received, and after the DCN packet in the IP format is re-packetized, the DCN packet is encapsulated in the management code block. Or forming a DCN message in an IP format according to the DCN message, and sending the DCN message in the IP format to a DCN network.
As shown in fig. 2, an interworking schematic of the out-of-band DCN and FlexE networks is shown. That is, on the link 23 where the egress of the FlexE network 21 is connected to the DCN switch 22, the DCN message in the conventional IP format is transmitted, and the existing DCN switch device does not need to be modified. Inside the FlexE network, the DCN packets are transferred, which are repackaged by the FlexE device according to 32 bits, the repackaged packets being encapsulated in a newly defined management code block Payload. And after the target receiving point is reached, the DCN message can be restored again according to the sequence number Seq.
As shown in fig. 3, a flowchart of a message processing method according to an embodiment of the present invention is applied to FlexE devices, and includes:
step 301, receiving a DCN message; the DCN message is formed by replacing an IDLE code block in the original data stream with a management code block, wherein the management code block is used for bearing a management control message.
And 302, acquiring a management control message according to the DCN message.
The meaning of each field of the management code block can be referred to the description of the foregoing embodiment.
Then, in step 302, the transmission sequence number of the management code block is obtained according to the sequence number field of the management code block. And then, according to the sending sequence number, arranging the management code blocks to obtain a management control message. In addition, the management control message can be checked according to the check field.
