Description

Message transmission method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting a packet, and a storage medium.

Background

In a segment routing Protocol version 6, SRv6 network based on the sixth version of Internet Protocol, a message header of a transmitted SRv6 message needs to carry a Segment Routing Header (SRH), and a Segment List (SL) included in the SRH is a path sequence composed of Segment Identifiers (SID) of each node on a message forwarding path. Where each SID has a standard byte length of 128 bits (bits).

However, as each SID is added to the SL, the length of the SRH will be increased by 128 bits, and the length of the packet will also be increased by 128 bits. When the forwarding path is too long, the length of the header byte of the SRv6 message is too long, thereby reducing the transmission efficiency of the message information. When the message length exceeds the Maximum Transmission Unit (MTU) of the network, the message transmission cannot be performed.

The following describes a message transmission method provided in an 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 method includes a process of establishing an index relationship between the node device and the simplified identifier by the server (referred to as an "index relationship establishment process" for short) and a process of performing message transmission from the first node device to the second node device corresponding to the simplified identifier of the second node device (referred to as a "message transmission process" for short).

The "index relationship establishing flow" is described first below.

As shown in fig. 4, the method of "index relationship establishing flow" is applied to a server, and includes: S401-S402.

S401, the server obtains the initial identification of the node equipment.

Specifically, in order to enable the server to establish the simplified identifier of the node device with the byte length smaller than the initial identifier of the node device, the server may obtain the initial identifier of the node device.

The node equipment comprises first node equipment and second node equipment.

Optionally, the method for the server to obtain the initial identifier of the node device may be to receive the initial identifier sent by the node device.

Optionally, before the server receives the initial identifier sent by the node device, a request message for obtaining 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.

Optionally, when the initial identifier of the node device is changed, a message for changing the initial identifier 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 whose byte length is smaller than the initial identifier of the node device, so as to obtain an index relationship between the node device and the simplified identifier.

The simplified identifiers correspond to the node devices one to one.

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, and may be specifically set according to actual requirements.

Illustratively, the server obtains that the initial identifier of the node device 1 is the standard SID "AAAA" (128bit), the initial identifier of the node device 2 is the standard SID "BBBB" (128bit), and the initial identifier of the node device 3 is the standard SID "CCCC" (128bit), and the established index relationship is as follows: the simplified identification of the node device 1 is "a" (32bit), the simplified identification of the node device 2 is "B" (32bit), and the simplified identification of the node device 3 is "C" (32 bit).

The "message transmission flow" is described first.

As shown in fig. 5, the method of "message transmission flow" is applied to the first node device, and includes: S501-S504.

S501, the first node device obtains a simplified identifier of a second node device for transmitting an initial message.

Wherein the byte length of the reduced identification is smaller than the byte length of the initial identification of the second node device.

Specifically, in the message transmission process, the first node device may extract, from the simplified identifier sequence for transmitting the initial message carried by the message header of the initial message, the simplified identifier of the next-hop node device from the simplified identifier of the first node device, and determine the simplified 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.

Optionally, the first node device may be a source node device or an intermediate node device.

Optionally, the simplified identification sequence may be established by the first node device, or may be established by the server.

Optionally, the initial message may be any SRv6 message.

S502, the first node device obtains a destination address corresponding to the simplified identification of the second node device.

Specifically, after obtaining the simplified identifier of the second node device, the first node device may obtain a destination address corresponding to the simplified identifier of the second node device, so that the band transmission data in the initial message is transmitted to the second node device indicated by the destination address.

Optionally, after obtaining the simplified identifier of the second node device, the first node device may send, to the server, a target request message including the simplified identifier of the second node device. The server responds to the target request message, reads the pre-established index relation between the node equipment and the simplified identification, determines the initial identification of the second node equipment corresponding to the simplified identification of the second node equipment, and sends a target response message including the initial identification of the second node equipment to the first node equipment. The first node device determines an initial identity of the second node device as the destination address in response to the target response message.

Illustratively, the index relationship established by the preset server is as follows: the simplified identification of the node device 1 is "a" (32bit), the simplified identification of the node device 2 is "B" (32bit), and the simplified identification of the node device 3 is "C" (32 bit). The simplified identifier of the second node device acquired by the first node device is "a". The first node device sends a target request message including a reduced identification "a" to the server. The server determines that the initial identifier of the second node device corresponding to the simplified identifier "A" is a standard SID "AAAA", and transmits a target response message including the standard SID "AAAA" to the first node device. The first node apparatus determines the 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 to generate a target message.

And when the first node equipment is the intermediate node equipment, the first node equipment updates the initial address in the initial message into the destination address to obtain the target message.

S504, the first node device sends the target message to the second node device according to the destination address.

Specifically, after generating the target packet, the first node device may transmit the target packet to the second node device indicated by the destination address according to the destination address carried in the packet header of the target packet.

Optionally, the second node device may be an intermediate node device or a tail node device.

S601, the first node equipment sends a first request message to the server.

The first request message is used for requesting to acquire an index relationship between the node equipment and the simplified identifier, which is pre-established by the server.

Specifically, in the message transmission process, after acquiring the initial message, the first node device may send a first request message 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 pre-established index relationship between the node device and the simplified identifier 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 packet.

S603, the first node device reads the index relation and determines the simplified identification corresponding to the second node device.

Specifically, after receiving the index relationship, the first node device may replace the path sequence carried in the packet header of the initial packet with the simplified identifier sequence, and then extract the simplified identifier of the next-hop node device of the simplified identifier of the first node device from the simplified identifier sequence, and determine the simplified identifier of the second node device.

Illustratively, the index relationship established by the preset server is as follows: the simplified identification of the node device 1 is "a" (32bit), the simplified identification of the node device 2 is "B" (32bit), and the simplified identification of the node device 3 is "C" (32 bit). The path sequence for transmitting the initial packet 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 transmits the index relationship to the node apparatus 3 in response to the first request message. The node device 3 replaces the path sequence carried in the packet header of the initial packet with the simplified identifier sequence "C-a-B" according to the index relationship, and determines that the simplified identifier "a" of the next-hop node device is the simplified identifier of the second node device.

In an embodiment, with reference to fig. 5, as shown in fig. 7, when the simplified identifier sequence is a server establishment, the method for the first node device to obtain the simplified identifier of the second node device for transmitting the initial packet in S501 specifically includes: S701-S703.

Specifically, in the message transmission process, after the first node device obtains the initial message, the second node device may send a second request message to the server, so that the first node device obtains the simplified identifier of the second node device.

Optionally, the second request message includes an initial identifier of the first node device and a path sequence of the initial packet.

S702, the server reads the pre-established index relationship between the node equipment and the simplified identifier, and determines the simplified identifier 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 acquire a path sequence for transmitting the initial packet. And then, the server reads the pre-established index relationship between the node equipment and the simplified identifier, and determines the simplified identifier corresponding to the next-hop node equipment of the first node equipment in the path sequence as the simplified identifier of the second node equipment.

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, obtains a path sequence for transmitting the initial message as 'node equipment 3-node equipment 1-node equipment 2', determines that the next hop node equipment of the node equipment 3 is the node equipment 1, and determines the simplified identifier 'A' of the node equipment 1 as the simplified identifier of the second node equipment.

S703, the first node device receives the simplified identifier of the second node device sent by the server.

The simplified identifier of the second node device is determined by the server reading the pre-established index relationship between the node device and the simplified identifier.

Specifically, after the server determines the simplified identifier of the second node device, the first node device may receive the simplified identifier of the second node device sent by the server.

In an embodiment, with reference to fig. 5, as shown in fig. 8, when the first node device is a source node device that transmits data to be transmitted, the method for the first node device to obtain a simplified identifier of a second node device that is used for transmitting an initial packet in S501 specifically includes: and S801.

Specifically, when the first node device is a source node device for transmitting data to be transmitted, the first node device may obtain simplified identifiers of all node devices for transmitting the data to be transmitted, so that the first node device establishes simplified identifier sequences of all nodes for transmitting the data to be transmitted to replace a path sequence in a header of the initial packet.

In an embodiment, with reference to fig. 5, as shown in fig. 9, when the first node device is a source node device that transmits data to be transmitted, the method for generating, by the first node device in S503, a target packet according to a destination address and an initial packet specifically includes: and S901.

Specifically, after the destination address corresponding to the simplified identifier of the second node device is obtained, the first node device may add the destination address to the initial message to obtain the target message.

In an embodiment, with reference to fig. 5, as shown in fig. 10, when the first node device is an intermediate node device for transmitting data to be transmitted, the method for the first node device to obtain the simplified identifier of the second node device for transmitting the initial packet in S501 specifically includes: and S1001.

S1001, when the first node device is an intermediate node device for transmitting data to be transmitted, the first node device obtains simplified identifications of next hop node devices adjacent to the first node device in all node devices for transmitting the data to be transmitted.

Specifically, when the first node device is an intermediate node device for transmitting data to be transmitted, the first node device may obtain a simplified identifier of a next hop node device adjacent to the first node device in all node devices for transmitting the data to be transmitted, so that the first node device determines a destination address of packet transmission according to the simplified identifier of the next hop node device.

In an embodiment, with reference to fig. 5, as shown in fig. 11, when the first node device is an intermediate node device that transmits data to be transmitted, the method for the first node device to generate the target packet according to the destination address and the initial packet in S503 specifically includes: s1101.

S1101, the first node equipment updates the initial address in the initial message to be a destination address so as to obtain a target message.

Specifically, after the destination address corresponding to the simplified identifier of the second node device is obtained, the first node device may update the initial address in the initial message to the destination address, so as to obtain the target message.

In summary, in the message transmission process, the message transmission apparatus in the embodiment of the present application obtains the simplified identifier of the second node device for transmitting the initial message, where a byte length of the simplified identifier is smaller than a byte length of the initial identifier of the second node device, then obtains the destination address corresponding to the simplified identifier of the second node device, generates the target message, and then sends the target message to the second node device according to the destination address. Therefore, the initial identifier in the path sequence carried by the message header can be replaced by the simplified identifier with shorter byte length, the byte length of the message header of the initial message is effectively shortened, and the message transmission efficiency is improved.
