Detailed Description
The embodiment of the application provides a segment route transmission method, a server, a source node and a storage medium based on VXLAN, which are used for introducing a decremental label thought of segment route, and the VXLAN forwarding table is not required to be inquired, so that the data packet forwarding efficiency is improved.
In order for those skilled in the art to better understand the present application, the following description will describe embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. Based on the examples in this application, all shall fall within the scope of protection of this application.
With the development of network communication technology, cloud computing has become a new trend of enterprise IT (Information Technology ) construction at present by virtue of the advantages of high system utilization rate, low manpower/management cost, strong flexibility/expandability and the like. Server virtualization is one of core technologies of cloud computing, and is increasingly widely used. The widespread deployment of server virtualization technology has greatly increased the computational density of data centers. However, conventional VLAN (Virtual Local Area Network ) is currently the mainstream network isolation technology, and there are only 12 bits in the standard definition, so the number of available VLANs is only 4096. For the scenario of tens of thousands or even more tenants, such as public clouds or other large virtualized cloud computing services, the isolation capability of VLANs cannot be met.
VLAN extensions VXLAN (Virtual eXtensible Local Area Network, virtual extended local area network) gradually appear. The VXLAN encapsulates the original message sent by the VM in the same area planned by the administrator into a new UDP (User Datagram Protocol ) message, and uses the IP (Internet Protocol ) and MAC (Medium Access Control, media access control) addresses of the physical network as the outer header, so that the network requirement for the MAC address specification is greatly reduced. In addition, VXLAN introduces a user identifier similar to VLAN ID, called VXLAN network identifier (VXLAN Network Identifier, VNI), which is composed of 24 bits, and supports VXLAN segments up to 16M, so that the problem of isolation of a large number of tenants in cloud computing is effectively solved.
In an existing implementation manner, in the current VXLAN network communication method, a source node transmits a data Packet (Packet), and in the transmission process, the source node needs to query a VXLAN forwarding table in each transit POP, and finally reaches a destination node. Fig. 1 is a schematic diagram of a VXLAN network communication method in one implementation.
Suppose a is a source node, X, Y, Z are destination nodes (in a real scenario, the number of destination nodes is large), and B-G are transit POPs. The packet sending paths are respectively as follows: a- > B- > E- > G- > Z, A- > B- > D- > F- > Y, A- > B- > C- > E- > X;
examples: the path is: the data plane forwarding process of A- > B- > E- > G- > Z is as follows:
step 1: the source end node A sends a packet to the source end node B through a network identifier vni1 corresponding to the current user;
step 2: b, inquiring a VXLAN route forwarding table, finding out vin6 corresponding to vni1, and going to E from the next hop;
step 3: after the data packet reaches E, E queries own VXLAN route forwarding table, finds the label vni11 corresponding to vni5, and the next hop is to POP: g, G;
step 4: after the data packet reaches G, G queries own VXLAN forwarding table, finds the identifier vni14 corresponding to vni11, and the next hop is to the destination node: z;
step 5: and (5) ending.
In another existing implementation manner, a method of differentially combining VXLAN and Segment Routing (SR) is proposed. Aiming at the VXLAN virtual channel at the user edge, the SR decreasing label method is adopted in the intermediate transmission process, but the method has some disadvantages: 1. the network address translation (NAT Network Address Translation) maps address changes, and the public network IP (Internet Protocol ) of the transit POP is often switched, and cannot be supported. 2. The edge node cannot be supported to be placed in the intranet of the local area network. As shown in fig. 2, a schematic diagram of the principle of forwarding by the segment routing SR is shown.
The segment routing SR forwarding principle is as follows:
the basic idea of SR is to divide the network into different segments (segments) and then splice up a label stack (Segment List) for guiding packet (Pkt) forwarding along a specified path, and each time forwarding, the used SID (Segment Identifier, segment identification) is removed from the label stack.
Label stack (Segment List): the label stack is an ordered set of destination address prefix SID (Segment Identifier, segment identification)/node SID and adjacency SID ordered list for identifying a complete LSP (Label Switched Path ). Label stacks are in MPLS (Multi-Protocol Label Switching, multiprotocol label switching) architecture, encapsulated in a header to direct forwarding.
Segment: instructions that the node executes on the ingress message (e.g., forward the message to the destination according to the shortest path, forward the message through a designated interface, or forward the message to a designated application/service instance).
SID (Segment ID, segment identification): segment Routing (Segment Routing) defines destination address prefixes/nodes and adjacencies in the network as individual segments and assigns Segment IDs to these destination address prefixes/nodes and adjacencies. The segment ID corresponds to an MPLS label in conventional MPLS technology, and maps to an MPLS label at the forwarding level.
Aiming at the problems, the application provides a segment route transmission method based on VXLAN. By referring to a Segment Routing (SR) forwarding mechanism (segment decrementing), a controller (controller) of a control plane calculates an optimal routing path (such as shortest RTT (Round Trip Time) and maximum bandwidth redundancy) by collecting network cards and routing information of a transit POP in real Time, and issues network configuration information of the optimal path to a source node, and the source node performs decrementing transmission according to the network configuration information until reaching a destination node. In addition, the whole transmission process is virtualized through VXLAN (the VXLAN virtual channel is adopted from the user end to the receiving end), and the method and the device can support the embodiment of the application and avoid communication interruption caused by various complex conditions aiming at complex network conditions, such as the change of source node mapping in an intranet and NAT and the change of POP public network IP.
In the following, by way of example, the technical solution of the present application is further described, as shown in fig. 3, which is a schematic diagram of an embodiment of a VXLAN-based segment route transmission method in the embodiment of the present application, and may include:
301. the server acquires network cards and route detection information of the source node, the target node and the transfer node.
Optionally, the network card includes a physical address, a gateway, and a public network protocol.
Optionally, the server obtains network card and route detection information of the source node, the target node, and the transit node, which may include:
the server receives network cards and route detection information sent by a source node, a target node and a transfer node; or alternatively, the first and second heat exchangers may be,
the server sends a report request to the source node, the target node and the transfer node, wherein the report request is used for reporting network card and route detection information by the source node, the target node and the transfer node, and receiving the network card and route detection information sent by the source node, the target node and the transfer node.
It is understood that a controller (controller) of a control plane in the server may collect network cards (MAC addresses (Media Access Control Address, physical addresses, also called hardware addresses), gateways, public network IP, etc.) of a source node, a destination node, and a transit node POP, and route probe information in real time.
302. And the server determines a routing path from the source node to the target node according to the network card of the transfer node and the routing detection information.
Optionally, the routing path includes a shortest routing path.
It can be understood that a controller (controller) of a control plane in the server calculates according to the acquired network cards of the source node, the destination node and the transit node POP and the route detection information, and at this time, an optimal route path (i.e., a shortest RTT path) from the source node to the destination node is assumed to be a- > B- > E- > G- > Z.
303. The server sends network configuration information to the source node, wherein the network configuration information comprises a routing path from the source node to the target node, and the routing path from the source node to the target node is used for the source node to forward the decremental identification of the data to the target node.
The source node receives network configuration information sent by the server, wherein the network configuration information comprises a routing path from the source node to the target node.
It can be understood that a controller (controller) of the control plane in the server issues network configuration information (Segment List) of the optimal routing path to the source node.
304. And the source node forwards the decremental identification of the data to the target node according to the route path from the source node to the target node.
Optionally, the routing path from the source node to the target node includes: a routing path from the source node to a first transit node, the first transit node to the target node; the forwarding the decremental identification of the data to the target node by the source node according to the routing path from the source node to the target node may include:
the source node sends a first data packet to the first transfer node, wherein the first data packet comprises a network identifier from the source node to the first transfer node and a network identifier from the first transfer node to the target node; and the source node sends a second data packet to the target node through the first transfer node, wherein the second data packet removes the network identifier from the source node to the first transfer node for the first transfer node and comprises the data packet from the first transfer node to the network identifier of the target node.
It will be appreciated that the network identification may be carried in the header of the data packet.
Illustratively, the source node sends a data Packet (Packet) to the transit node B through the network identifier 1 (vni 1) according to the Segment List; after receiving the Packet, the transit node B removes vni1 in the Segment List, and forwards the Packet to the transit node E through vni 2; after receiving the Packet, the transit node E removes vni2 of the Segment List, and forwards the Packet to the transit node G through vni 3; after receiving the Packet, the transit node G removes vni3 of the Segment List, and forwards the Packet to the target node Z through vni 4. Fig. 4 is a schematic diagram illustrating another embodiment of the VXLAN-based segment routing method in the embodiment of the present application.
The invention provides a segment route transmission method based on VXLAN technology. The Controller of the control plane dynamically calculates the optimal route path (such as shortest RTT and maximum bandwidth redundancy) by collecting network cards and route information of all nodes in real time, and issues network configuration information (Segment List) of the optimal route to the source node, and the source node performs decreasing transmission according to the Segment List until reaching the destination node. In addition, the whole transmission process is virtualized through VXLAN, and aiming at complex network conditions, such as the mapping change of a source node in an intranet and NAT, the change of the POP public network IP is transferred, so that the method can support the change of the POP public network IP, and the communication interruption caused by various complex conditions is avoided.

And fusing the full-course VXLAN virtual channel transmission with the descending label thought of the SR route. The descending label thought of the segmented route is introduced, a VXLAN forwarding table is not required to be queried, the forwarding efficiency of data packet forwarding is improved, the use of vni is reduced, and the risk that the vni is exhausted is reduced. The whole network communication process is a virtualized channel, and network communication interruption caused by network condition change (NAT mapping change and public network IP change transfer in the process of network communication of edge nodes) can be avoided.
