Description

Message transmission method, device and storage medium
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting a message, and a storage medium.
Background
In a sixth version of internet protocol based segment routing (segment routing Internet Protocol version, srv 6) network, a segment routing header (segment routing header, SRH) needs to be carried in a header of a SRv packet transmitted, where the SRH includes a Segment List (SL) that is a path sequence consisting of segment identifiers (segment identifier, SID) of the nodes on the packet forwarding path. Wherein each SID has a standard byte length of 128 bits (bits).
However, since the length of the SRH increases by 128 bits for every SID added to the SL, the length of the message also increases by 128 bits. When the forwarding path is too long, the length of the message header byte of the SRv6 message is too long, so that the transmission efficiency of the message information is reduced. When the message length exceeds the network maximum transmission unit (maximum transmission unit, MTU), no message transmission is possible.

The following describes the message transmission method provided in the embodiment of the present application in detail with reference to the accompanying drawings.
The message transmission method provided by the embodiment of the application comprises the following steps: the server establishes an index relation between the node device and the simplified identifier (referred to as an "index relation establishment procedure") and transmits a message to the second node device corresponding to the simplified identifier of the second node device by the first node device (referred to as a "message transmission procedure").
The "index relationship establishment flow" is described first below.
As shown in fig. 4, the method of "index relationship establishment procedure" is applied to a server, and includes: S401-S402.
S401, the server acquires the initial identification of the node equipment.
Specifically, in order for the server to establish a simplified identification of the node device having a byte length smaller than the initial identification of the node device, the server may acquire the initial identification of the node device.
The node equipment comprises first node equipment and second node equipment.
Alternatively, the method of obtaining the initial identifier of the node device by the server may be that the initial identifier sent by the node device is received.
Alternatively, before the server receives the initial identifier sent by the node device, a request message for acquiring the initial identifier may be sent to the node device, and the node device sends the initial identifier to the server in response to the request message.
Alternatively, when the initial identity of the node device is changed, a message for changing the initial identity may be sent to the server.
Optionally, the node device may also periodically send the updated initial identifier to the server.
Alternatively, the initial identification may be a standard SID.
S402, the server establishes an index relation between the node equipment and the simplified identifier.
Specifically, after the initial identifier of the node device is obtained, the server may establish a simplified identifier of the node device having a byte length smaller than the initial identifier of the node device, so as to obtain an index relationship between the node device and the simplified identifier.
Wherein the simplified identifications are in one-to-one correspondence with the node devices.
Optionally, when the initial identifier is the standard SID, the byte length of the simplified identifier of the standard SID is any length smaller than 128 bits, which can be specifically set according to the actual requirement.
For example, the server obtains the initial identifier of the node device 1 as the standard SID "AAAA" (128 bit), the initial identifier of the node device 2 as the standard SID "BBBB" (128 bit), and the initial identifier of the node device 3 as the standard SID "CCCC" (128 bit), and the established index relationship is: the reduced identification of the node device 1 is "a" (32 bit), the reduced identification of the node device 2 is "B" (32 bit), and the reduced identification of the node device 3 is "C" (32 bit).
The following describes the "message transmission flow".
As shown in fig. 5, the method of the "message transmission flow" is applied to the first node device, and includes: S501-S504.
S501, the first node equipment acquires a simplified identification of the second node equipment for transmitting the initial message.
Wherein the reduced identity has a byte length that is less than the byte length of the initial identity of the second node device.
Specifically, in the message transmission process, the first node device may extract, from the reduced identifier sequence carried by the header of the initial message and used for transmitting the initial message, the reduced identifier of the next-hop node device that extracts the reduced identifier of the first node device, and determine the reduced identifier as the reduced identifier of the second node device.
The simplified identification sequence is composed of a plurality of simplified identifications, and the byte length of the simplified identification sequence is smaller than that of the path sequence.
Alternatively, the first node device may be a source node device, or an intermediate node device.
Alternatively, the reduced identification sequence may be established by the first node device or by the server.
Alternatively, the initial message may be any SRv6 message.
S502, the first node equipment acquires a destination address corresponding to the simplified identifier of the second node equipment.
Specifically, after the simplified identifier of the second node device is obtained, the first node device may obtain a destination address corresponding to the simplified identifier of the second node device, so as to transmit the band transmission data in the initial packet to the second node device indicated by the destination address.
Alternatively, after obtaining the reduced identifier of the second node device, the first node device may send a target request message including the reduced identifier of the second node device to the server. The server responds to the target request message, reads the index relation between the pre-established node equipment and the simplified identifier, determines the initial identifier of the second node equipment corresponding to the simplified identifier of the second node equipment, and sends a target response message comprising the initial identifier of the second node equipment to the first node equipment. The first node device determines an initial identity of the second node device as a destination address in response to the target response message.
The index relationship established by the preset server is as follows: the reduced identification of the node device 1 is "a" (32 bit), the reduced identification of the node device 2 is "B" (32 bit), and the reduced identification of the node device 3 is "C" (32 bit). The reduced identity of the second node device obtained by the first node device is "a". The first node device sends a target request message to the server including a reduced identity "a". The server determines an initial identification of the second node device corresponding to the reduced identification "a" as a standard SID "AAAA" and transmits a target response message including the standard SID "AAAA" to the first node device. The first node device determines a standard SID "AAAA" as the destination address.
S503, the first node equipment generates a target message according to the destination address and the initial message.
Specifically, after the destination address corresponding to the simplified identifier of the second node device is obtained, the first node device generates a target message according to the destination address and the initial message.
Optionally, when the first node device is a source node device, the first node device adds the destination address to the initial message, and generates the target message.
When the first node equipment is intermediate node equipment, the first node equipment updates the initial address in the initial message into a target address to obtain a target message.
S504, the first node equipment sends the target message to the second node equipment according to the destination address.
Specifically, after the target message is generated, the first node device may transmit the target message to the second node device indicated by the destination address according to the destination address carried in the message header of the target message.
Alternatively, the second node device may be an intermediate node device, or a final node device.
In one embodiment, as shown in fig. 6 in conjunction with fig. 5, when the reduced identifier sequence is established by the first node device, the method for the first node device to obtain the reduced identifier of the second node device for transmitting the initial message in S501 specifically includes: S601-S603.
S601, the first node equipment sends a first request message to a server.
The first request message is used for requesting to acquire an index relation between node equipment and a simplified identifier, which is pre-established by the server.
Specifically, in the process of message transmission, after the first node device acquires the initial message, a first request message may be sent to the server, so that the first node device acquires an index relationship between the node device and the simplified identifier, which is pre-established by the server.
S602, the first node equipment receives the index relation sent by the server.
Specifically, after the first node device sends the first request message to the server, the server responds to the first request message and sends the index relation between the node device and the simplified identifier, which is established in advance, to the first node device, so that the first node device can determine the simplified identifier sequence according to the path sequence for transmitting the initial message.
S603, the first node equipment reads the index relation and determines a simplified identification corresponding to the second node equipment.
Specifically, after receiving the index relationship, the first node device may replace the path sequence carried in the header of the initial message with a simplified identifier sequence, and then determine, as the simplified identifier of the second node device, the simplified identifier of the next hop node device from which the simplified identifier of the first node device is extracted in the simplified identifier sequence.
The index relationship established by the preset server is as follows: the reduced identification of the node device 1 is "a" (32 bit), the reduced identification of the node device 2 is "B" (32 bit), and the reduced identification of the node device 3 is "C" (32 bit). The path sequence of the transmission initial message acquired by the node device 3 is "node device 3-node device 1-node device 2".
After receiving the initial message, the node device 3 sends a first request message to the server. The server sends the index relation to the node device 3 in response to the first request message. The node device 3 replaces the path sequence carried in the header of the initial message with the simplified identification sequence "C-se:Sub>A-B" according to the index relationship, and determines that the simplified identification "se:Sub>A" of the next hop node device is the simplified identification of the second node device.
In one embodiment, as shown in fig. 7 in conjunction with fig. 5, when the reduced identifier sequence is a server setup, the method for the first node device to obtain the reduced identifier of the second node device for transmitting the initial message in S501 specifically includes: S701-S703.
S701, the first node device sends a second request message to the server.
Wherein the second request message is for requesting to obtain a reduced identity of the second node device.
Specifically, in the process of message transmission, after the first node device acquires the initial message, a second request message may be sent to the server, so that the first node device acquires the simplified identifier of the second node device.
Optionally, the second request message includes an initial identification of the first node device and a path sequence of the initial message.
S702, the server reads the index relation between the pre-established node equipment and the simplified identification, and determines the simplified identification of the second node equipment.
Specifically, after the first node device sends the second request message to the server, the server responds to the second request message to obtain a path sequence for transmitting the initial message. Then, the server reads the index relation between the pre-established node equipment and the simplified identification, and determines the simplified identification corresponding to the next hop node equipment of the first node equipment in the path sequence as the simplified identification of the second node equipment.
The index relationship established by the preset server is as follows: the reduced identification of the node device 1 is "a" (32 bit), the reduced identification of the node device 2 is "B" (32 bit), and the reduced identification of the node device 3 is "C" (32 bit). The path sequence of the transmission initial message acquired by the node device 3 is "node device 3-node device 1-node device 2".
After receiving the initial message, the node device 3 sends a second request message to the server. The server responds to the second request message, acquires a path sequence for transmitting the initial message as 'node equipment 3-node equipment 1-node equipment 2', determines the next hop node equipment of the node equipment 3 as the node equipment 1, and determines a simplified identifier 'A' of the node equipment 1 as a simplified identifier of the second node equipment.
S703, the first node equipment receives the simplified identification of the second node equipment sent by the server.
The simplified identifier of the second node device is determined by the server reading the index relation between the pre-established node device and the simplified identifier.
Specifically, after the server determines the reduced identifier of the second node device, the first node device may receive the reduced identifier of the second node device sent by the server.
