Description

Background Art

[0002] Segment Routing (SR) is a tunneling technology based on source routing. It selects a forwarding path based on the source information and encapsulates the path information to the destination address and the network information of the destination address in the header of the message. Segment routing can be applied to two types of networks: one is segment routing based on MPLS (Multi-Protocol Label Switching), referred to as SR-MPLS; the other is segment routing based on IPv6, referred to as SRv6. SR-MPLS networks have been deployed in large quantities. If SRv6 networks need to be incrementally deployed on this basis, SRv6 networks need to coexist and communicate with MPLS networks. However, due to the differences in data planes, the two networks have their own transmission message formats, and SRv6 networks cannot directly or simply communicate with MPLS networks.

[0003] At present, in the related technology, the communication between SRv6 network and MPLS network is established by establishing VPN (Virtual Private Network) or message mutual encapsulation. Among them, the solution of establishing VPN needs to plan and configure IP address and VRF (Virtual Routing Forwarding) on ​​the newly established virtual link, which has the problem of waste of equipment resources; and the solution of message mutual encapsulation needs to encapsulate the header that can be recognized by the other end during communication, which has the problem of cumbersome steps.

[0038] For ease of understanding, several terms involved in the present disclosure are explained below:

[0039] MPLS: The full name is Multi-Protocol Label Switching, which is a new technology that uses labels to guide high-speed and efficient data transmission on an open communication network.

[0043] SID: The full name is Segment ID. It is a special IPv6 address used to uniquely identify each segment in SRv6. It has both the routing capabilities of a common IPv6 address and the behavior capabilities unique to SRv6.

[0044] Figure 1 A schematic diagram of a network communication system architecture in an embodiment of the present disclosure is shown. The network communication method and device provided in the embodiment of the present disclosure can be applied but not limited to Figure 1 A network communication system is shown.

[0045] like Figure 1 As shown, the network communication system includes: a first network 101 and a second network 102; wherein the first network 101 includes: a first edge device 1011 and a first core device 1012; the second network 102 includes: a second edge device 1021 and a second core device 1022.

[0046] In the embodiment of the present disclosure, the first network 101 and the second network 102 refer to networks using different communication protocols. The first edge device 1011 and the second edge device 1021 refer to network devices that support both the first network 101 communication protocol and the second network 102 communication protocol; the first core device 1012 refers to a network device that only supports the first network 101 communication protocol; and the second core device 1022 refers to a network device that only supports the second network 102 communication protocol.

[0047] In one embodiment of the present disclosure, the first network 101 may be an SRv6 network, and the second network 102 may be an MPLS network; in another embodiment of the present disclosure, the first network 101 may be an MPLS network, and the second network 102 may be an SRv6 network.

[0048] Taking the first network 101 as an SRv6 network and the second network as an MPLS network as an example, a pseudo MPLS label can be assigned to the SRv6 device (i.e., the first core device 1012) in the SRv6 network that only supports the SRv6 communication protocol; at the same time, a pseudo SID can be assigned to the MPLS device (i.e., the second core device 1022) in the MPLS network that only supports the MPLS communication protocol.

[0049] Furthermore, one or more pseudo SIDs corresponding to the second core devices 1022 are flooded in the SRv6 network so that the first edge device 1011 receives the MPLS message from the MPLS network, and when the MPLS message carries a pseudo MPLS label, the MPLS message is converted into an SRv6 message based on the pre-configured mapping relationship between the SID and the pseudo MPLS label; and the converted SRv6 message is sent to the first core device 1012 in the SRv6 network, so as to realize data transmission from the MPLS network to the SRv6 network.

[0050] Furthermore, the pseudo MPLS labels corresponding to one or more first core devices 1012 are flooded in the MPLS network so that the second edge device 1021 receives the SRv6 message from the SRv6 network, and when the SRv6 message carries a pseudo SID, the SRv6 message is converted into an MPLS message based on a pre-configured mapping relationship between the MPLS label and the pseudo SID; and the converted MPLS message is sent to the second core device 1022 in the MPLS network, so as to realize data transmission from the SRv6 network to the MPLS network.

[0051] Those skilled in the art will know that Figure 1 The number of networks, edge devices, and core devices shown in the figure is only for illustration, and any number of networks, edge devices, and core devices may be provided according to actual needs, and the embodiments of the present disclosure are not limited thereto.

[0052] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0053] First, an embodiment of the present disclosure provides a network communication method from an SRv6 network to an MPLS network, which can be executed by any electronic device with computing and processing capabilities.

[0054] Figure 2 A flow chart of a network communication method from an SRv6 network to an MPLS network in an embodiment of the present disclosure is shown. Figure 2 As shown, the network communication method includes the following steps:

[0055] Step S202: receiving an SRv6 message from the SRv6 network, wherein the SRv6 message carries a SID of the SRv6 device or a pseudo SID of the MPLS device;

[0056] Step S204: when the SRv6 message carries the pseudo SID, the SRv6 message is converted into an MPLS message based on a pre-configured mapping relationship between the MPLS label and the pseudo SID;

[0057] Step S206: Send the converted MPLS message to the MPLS network.

[0058] It should be noted that the solution provided in the above steps S202 to S206 can be executed in the edge device of the MPLS network. When the edge device of the MPLS network receives the SRv6 message from the SRv6 network, it determines whether the SRv6 message carries a pseudo SID. When the SRv6 message carries a pseudo SID, based on the pre-configured mapping relationship between the MPLS label and the pseudo SID, the SRv6 message is converted into an MPLS message, and the converted MPLS message is sent to other network devices in the MPLS network.

[0059] Since devices in the MPLS network that do not support the SRv6 communication protocol cannot be treated as nodes by the SRv6 network, in order to achieve communication between the SRv6 network and the MPLS network, it is necessary to pre-allocate pseudo SIDs for one or more MPLS devices in the MPLS network that only support the MPLS communication protocol, and flood the pseudo SIDs corresponding to each MPLS device in the SRv6 network so that the SRv6 message can be decapsulated, re-encapsulated as an MPLS message, and sent to the MPLS network.

[0060] Furthermore, in order to identify whether an SRv6 message carries a pseudo SID, in one embodiment of the present disclosure, after allocating a pseudo SID to one or more MPLS devices that only support the MPLS communication protocol in the MPLS network, a first mapping table can be constructed based on the MPLS label of the MPLS device and the corresponding pseudo SID, so as to determine whether the SRv6 message carries a pseudo SID after receiving an SRv6 message from the SRv6 network; if the SID carried by the current SRv6 message is in the first mapping table, it indicates that the SID carried by the current SRv6 message is a pseudo SID; if the SID carried by the current SRv6 message is not in the first mapping table, it indicates that the SID carried by the current SRv6 message is not a pseudo SID, but a real SID of the SRv6 device.

[0061] In one embodiment of the present disclosure, the above step S204 can be implemented by the following steps: querying the MPLS label corresponding to the pseudo SID from the first mapping table; deleting the SRv6 header in the SRv6 message, adding an MPLS header containing the MPLS label corresponding to the pseudo SID, and obtaining the corresponding MPLS message. It can be seen that the embodiment of the present disclosure can realize the format conversion of messages transmitted by different networks by simply decapsulating and recapsulating the message, thereby quickly realizing the communication between the SRv6 network and the MPLS network.

[0062] Figure 3 A flowchart of an optional network communication method from an SRv6 network to an MPLS network in an embodiment of the present disclosure is shown. Figure 3 As shown, the network communication method from the SRv6 network to the MPLS network provided in the embodiment of the present disclosure may include the following steps:

[0063] Step S302, allocating a pseudo SID to an MPLS device that only supports the MPLS communication protocol in the MPLS network;

[0064] Step S304: construct a first mapping table according to the MPLS labels of each MPLS device and the corresponding pseudo SID, wherein the first mapping table includes: a mapping relationship between the MPLS label and the pseudo SID;

[0065] Step S306, flooding the pseudo SIDs corresponding to one or more MPLS devices in the SRv6 network, wherein each MPLS device corresponds to an MPLS label in the MPLS network;

[0066] Step S308: receiving an SRv6 message from the SRv6 network, wherein the SRv6 message carries the SID of the SRv6 device or the pseudo SID of the MPLS device;

[0067] Step S310: Based on the first mapping table, determine whether the SRv6 message carries a pseudo SID.

[0068] Step S312: when the SRv6 message carries a pseudo SID, query the MPLS label corresponding to the pseudo SID from the first mapping table;

[0069] Step S314, deleting the SRv6 header in the SRv6 message, adding an MPLS header, and obtaining a corresponding MPLS message, wherein the MPLS header includes an MPLS label corresponding to the pseudo SID; and

[0070] Step S316: Send the converted MPLS message to the MPLS network.

[0071] Secondly, the embodiment of the present disclosure also provides a network communication method from an MPLS network to an SRv6 network, which can also be executed by any electronic device with computing and processing capabilities.

[0072] Figure 4 A flow chart of a network communication method from an MPLS network to an SRv6 network in an embodiment of the present disclosure is shown. Figure 4 As shown, the network communication method includes the following steps:

[0073] Step S402: receiving an MPLS message from an MPLS network, wherein the MPLS message carries an MPLS label of an MPLS device or a pseudo MPLS label of an SRv6 device;

[0074] Step S404: when the MPLS message carries a pseudo MPLS label, convert the MPLS message into an SRv6 message based on a pre-configured mapping relationship between the SID and the pseudo MPLS label; and

[0075] Step S406: Send the converted SRv6 message to the SRv6 network.

[0076] It should be noted that the solution provided in the above steps S402 to S406 can be executed in the edge device of the SRv6 network. When the edge device of the SRv6 network receives an MPLS message from the MPLS network, it determines whether the MPLS message carries a pseudo MPLS label. When the MPLS message carries a pseudo MPLS label, based on the pre-configured mapping relationship between the SID and the pseudo MPLS label, the MPLS message is converted into an SRv6 message, and the converted SRv6 message is sent to the SRv6 network.

[0077] In order to realize the communication between the MPLS network and the SRv6 network, it is necessary to pre-allocate pseudo MPLS labels for the SRv6 devices that only support the SRv6 communication protocol in the SRv6 network, and flood the pseudo MPLS labels corresponding to one or more SRv6 devices in the MPLS network so as to decapsulate the MPLS packets, re-encapsulate them into SID packets, and send them to the SID network.

[0078] Furthermore, in order to identify whether an MPLS packet carries a pseudo MPLS label, in one embodiment of the present disclosure, after allocating a pseudo MPLS label to one or more SRv6 devices that only support the SRv6 communication protocol in the SRv6 network, a second mapping table can be constructed based on the SID of each SRv6 device and the corresponding pseudo MPLS label, so that after receiving an MPLS packet from the MPLS network, it is possible to determine whether the MPLS packet carries a pseudo MPLS label based on the second mapping table; if the MPLS label carried by the current MPLS packet is in the second mapping table, it indicates that the MPLS label carried by the current MPLS packet is a pseudo MPLS label; if the MPLS label carried by the current MPLS packet is not in the second mapping table, it indicates that the MPLS label carried by the current MPLS packet is not a pseudo MPLS label, but a real MPLS label of the MPLS device.

[0079] In one embodiment of the present disclosure, the above step S404 can be implemented by the following steps: querying the SID corresponding to the pseudo MPLS label from the second mapping table; deleting the MPLS header of the MPLS message, and adding a SID header containing the SID corresponding to the pseudo MPLS label.

[0080] Figure 5 A flowchart of an optional network communication method from an MPLS network to an SRv6 network in an embodiment of the present disclosure is shown. Figure 5 As shown, the network communication method may include the following steps:

[0081] Step S502, allocating a pseudo MPLS label to an SRv6 device that only supports the SRv6 communication protocol in the SRv6 network;

[0082] Step S504: construct a second mapping table according to the SID of each SRv6 device and the corresponding pseudo MPLS label, wherein the second mapping table includes: a mapping relationship between the SID and the pseudo MPLS label;

[0083] Step S506, flooding the pseudo MPLS labels corresponding to one or more SRv6 devices in the MPLS network, wherein each SRv6 device corresponds to a SID in the SRv6 network;

[0084] Step S508: receiving an MPLS message from the MPLS network, wherein the MPLS message carries an MPLS label of an MPLS device or a pseudo MPLS label of an SRv6 device;

[0085] Step S510: judging whether the MPLS message carries a pseudo MPLS label based on the second mapping table;

[0086] Step S512: when the MPLS message carries a pseudo MPLS label, query the SID corresponding to the pseudo MPLS label from the second mapping table;

[0087] Step S514, deleting the MPLS header of the MPLS message, adding the SID header, and obtaining a corresponding SID message, wherein the SID header includes the SID corresponding to the pseudo MPLS label;

[0088] Step S516: Send the converted SRv6 message to the SRv6 network.

[0089] As can be seen from the above, the network communication method provided in the embodiment of the present disclosure realizes the intercommunication between the SRV6 network and the MPLS network based on message conversion, and can realize the communication from the SRV6 network to the MPLS network, and can also realize the communication from the MPLS network to the SRV6 network. In the specific implementation, it mainly includes the following three aspects:

[0090] ① Label mapping: Configure the mapping relationship between MPLS labels and SRv6 SIDs. In an SRv6 network, flood the pseudo SIDs corresponding to the MPLS device labels; in an MPLS network, flood the pseudo MPLS labels corresponding to the SRv6 devices. Pseudo SIDs and pseudo MPLS labels can be specified manually or automatically assigned by the system, and ensure that there are no conflicts or overlaps, otherwise the configuration will be rejected.

[0091] ② Message reception and judgment: Receive the message and determine whether to convert the message based on the label mapping relationship.

[0092] ③ Message conversion and transmission: Flood the pseudo SID corresponding to the MPLS device label in the SRv6 network. When the message of the SRv6 network reaches the border router of the MPLS network, the border router converts the SRv6 message into an MPLS message according to the pre-configured mapping relationship between the pseudo SID and the MPLS label; Flood the MPLS pseudo label corresponding to the SRv6 device in the MPLS network. When the message of the MPLS network reaches the border router of the SRv6 network, the border router converts the MPLS message into an SRv6 message according to the pre-configured mapping relationship between the pseudo MPLS label and the SID.

[0093] The network communication method provided in the embodiment of the present disclosure can realize the identification of heterogeneous network devices by configuring pseudo labels and pseudo SIDs without using an additional routing calculation engine, thereby planning the optimal path; the conversion of different network messages is realized by decapsulating and re-encapsulating the messages, thereby reducing the message length of the transmitted messages and improving the transmission efficiency.

[0094] Below Figure 6 Taking the network shown in FIG. 1 as an example, the network communication method provided in the embodiment of the present disclosure is described in detail. Figure 6 As shown, nodes 1, 2, 6, and 7 in the network only support the SRv6 communication protocol, node 4 only supports the MPLS communication protocol, and nodes 3 and 5 serve as border routers and support both MPLS and SRv6 communication protocols.

[0095] In one embodiment of the present disclosure, Figure 7 The label mapping process shown in the figure implements the configuration of label mapping relationship, such as Figure 7 As shown, first, the mapping server function is configured on node 3, pseudo SIDs are allocated to nodes 4 and 5, and flooded to nodes 1 and 2; then the mapping server function is configured on node 5, pseudo labels are allocated to nodes 6 and 7, and flooded to nodes 4 and 3. Tables 1 and 2 show a possible configuration result.

[0096] Table 1 Label mapping relationship configured in node 3

[0097] MPLS Labels Pseudo SID 16004 B:4:End:: 16005 B:5:End::

[0098] Table 2 Label mapping relationship configured in node 5

[0099] SID Pseudo Labels B:6:End:: 16006 B:7:DT4:: 16007

[0100] Figure 8 A message forwarding flow chart of an embodiment of the present disclosure is shown as follows: Figure 8 As shown, nodes 1, 2, and 3 exchange messages through the SRv6 network. After receiving the message, node 3 searches the label mapping table and finds that B:4:End:: is a pseudo SID, corresponding to the MPLS label 16004 in the mapping table. Therefore, the SRv6 header in the message is deleted, the MPLS header is added, and the MPLS header is pushed in according to the mapping relationship. After the message reaches node 5, the label mapping table is searched and it is found that 16006 is a pseudo label, corresponding to B:6:End:: in the mapping table. Therefore, the MPLS header in the message is deleted, and the SRv6 header is added, and the corresponding SID is installed. After the message reaches node 7, all headers are popped out.

[0101] Based on the same inventive concept, the present disclosure also provides a network communication device in the following embodiments. Figure 2 The network communication method shown is similar, so the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.
