Detailed Description
The embodiment of the application provides a VXLAN-based segmented routing transmission method, a server, a source node and a storage medium, which are used for introducing a descending label thought of segmented routing without inquiring a VXLAN forwarding table, so that the forwarding efficiency of a data packet is improved.
For a person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. The embodiments in the present application shall fall within the protection scope of the present 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 ITs advantages of high system utilization rate, low manpower/management cost, strong flexibility/extensibility, and the like. Server virtualization is one of the core technologies of cloud computing, and is applied more and more widely. The wide deployment of server virtualization technologies has greatly increased the computational density of data centers. However, as a currently mainstream Network isolation technology, a conventional VLAN (Virtual Local Area Network) has only 12 bits in a standard definition, and thus the number of available VLANs is only 4096. For a scenario of tens of thousands or even more tenants, such as a public cloud or other large virtualized cloud computing service, the isolation capability of the VLAN cannot be satisfied.
A VLAN expansion scheme VXLAN (Virtual eXtensible Local Area Network) is gradually emerging. VXLAN encapsulates an original message sent by a VM in the same area planned by an administrator into a new UDP (User Datagram Protocol) message, and uses an IP (Internet Protocol) and a MAC (media Access Control) address of a physical network as an outer header, thereby greatly reducing the requirement of the network on the MAC address specification. In addition, the VXLAN introduces a user Identifier similar to a VLAN ID, which is called VXLAN Network Identifier (VNI), and is composed of 24 bits, and supports up to 16M VXLAN segments, thereby effectively solving the problem of isolation of mass tenants in cloud computing.
In an existing implementation manner, in a current VXLAN network communication method, a source node transmits a data Packet (Packet), and in a transmission process, a VXLAN forwarding table needs to be queried in each transit POP, and finally, a destination node is reached. Fig. 1 is a schematic diagram of a VXLAN network communication method in an implementation manner.
Suppose that a is a source end node, X, Y, and Z are destination nodes (in a real scene, the number of destination nodes is large), and B to 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;
example (c): the path is as follows: the data flat bread 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 routing forwarding table, finding a vin6 corresponding to vni1, and enabling a next hop to be E;
and step 3: after the data packet reaches E, E queries a VXLAN routing forwarding table of the E to find an identifier vni11 corresponding to vni5, and the next hop is to POP: g;
and 4, step 4: after the data packet reaches G, G queries a VXLAN forwarding table of the G to find an identifier vni14 corresponding to vni11, and the next hop is the destination node: z;
and 5: and (6) ending.
In another implementation of the prior art, a method for differentially combining VXLAN and Segment Routing (SR) is proposed. Aiming at the situation that the user edge end is a VXLAN virtual channel, the intermediate transmission process adopts an SR label descending method, but the method has some defects: 1. the Network Address Translation (NAT) cannot be supported when a NAT (Network Address Translation) mapping Address changes and a public Network IP (Internet Protocol) for transferring POP is frequently switched. 2. The edge node can not be supported to be placed in the local area network. As shown in fig. 2, a schematic diagram of the segment routing SR forwarding principle is shown.
The segmented routing SR forwarding principle is as follows:
the basic idea of SR is to divide the network into different segments (segments), and then to splice up a Segment List (Segment List) for guiding packet forwarding according to a specified path, and to remove the used SID (Segment Identifier) from the Segment stack every time packet forwarding is performed.
Label stack (Segment List): the Label stack is an ordered set of destination address prefix (SID)/node (SID) and adjacent SID ordered lists, and is used to identify a complete LSP (Label Switched Path). In an MPLS (Multi-Protocol Label Switching) architecture, a Label stack is encapsulated in a packet header to direct forwarding.
Segment: the node is used for executing the instruction of the inlet message (such as forwarding the message to the destination according to the shortest path, or forwarding the message through a specified interface, or forwarding the message to a specified application/service instance).
SID (Segment ID), Segment identification: segment Routing (Segment Routing) defines destination address prefixes/nodes and adjacencies in a network as individual segments and assigns Segment IDs to these destination address prefixes/nodes and adjacencies. The segment ID is equivalent to an MPLS label in the conventional MPLS technology and is mapped to an MPLS label at the forwarding plane.
In order to solve the above problems, the present application provides a VXLAN-based segment routing transmission method. By using a Segment Routing (SR) forwarding mechanism (segment decrementing), a controller (controller) of a control plane calculates an optimal routing path (e.g., shortest Round-Trip Time (RTT) and maximum bandwidth redundancy) by acquiring network card and routing information of a transit POP in real Time, and sends network configuration information of the optimal path to a source node, and the source node performs decremental transmission according to the network configuration information until reaching a destination node. In addition, the invention virtualizes the whole transmission process through VXLAN (VXLAN virtual channels are adopted from the user side to the receiving end), aiming at complex network conditions, such as the change of the source node in the intranet and NAT mapping and the change of the transit POP public network IP, the embodiment of the invention can support the complex network conditions, and avoids the communication interruption caused by various complex conditions.
The following further describes the technical solution of the present application by way of an embodiment, as shown in fig. 3, which is a schematic diagram of an embodiment of a VXLAN-based segment routing transmission method in the embodiment of the present application, and the method may include:
301. the server acquires network cards and route detection information of a source node, a target node and a transit node.
Optionally, the network card includes a physical address, a gateway, and a public network protocol.
Optionally, the obtaining, by the server, network cards and route detection information of the source node, the target node, and the transit node may include:
the server receives network card and route detection information sent by a source node, a target node and a transit node; or the like, or, alternatively,
the server sends a reporting request to the source node, the target node and the transit node, wherein the reporting request is used for the source node, the target node and the transit node to report network cards and routing detection information, and receives the network cards and the routing detection information sent by the source node, the target node and the transit node.
It can be understood that a controller (controller) of a Control plane in the server may collect network cards (MAC addresses, physical addresses, which may also be referred to as hardware addresses), gateways, public network IP, and the like) and routing probe information of a source node, a destination node, and a transit node POP 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 transit node and the routing detection information.
Optionally, the routing path comprises the shortest routing path.
It can be understood that a controller (controller) of a control plane in the server calculates according to the collected network cards of the source node, the destination node, and the transit node POP and the route probe information, and at this time, an optimal route path (i.e., a shortest RTT path) from the source node to the destination node assumes that the optimal route path is 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 data to the target node by descending identification.
The method comprises the steps that a source node receives network configuration information sent by a server, wherein the network configuration information comprises a routing path from the source node to a 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 performs the decreasing identification forwarding of the data to the target node according to the routing 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 destination node; the performing, by the source node, decremental identifier forwarding of data to the target 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 transit node, wherein the first data packet comprises a network identifier from the source node to the first transit node and a network identifier from the first transit node to the target node; and the source node sends a second data packet to the target node through the first transit node, wherein the second data packet is a data packet obtained by removing the network identifier from the source node to the first transit node by the first transit node and including the network identifier from the first transit node to 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 Packet (Packet) to the transit node B through the network identifier 1(vni1) 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 of another embodiment of a VXLAN-based segment routing transmission method in the embodiment of the present application.
The invention provides a segmented routing transmission method based on VXLAN technology. The Controller of the control plane dynamically calculates the optimal routing path (such as the shortest RTT and the largest bandwidth redundancy) by acquiring the network cards and routing information of all nodes in real time, sends network configuration information (Segment List) of the optimal path to the source node, and the source node performs decremental transmission according to the Segment List until reaching the destination node. In addition, the invention virtualizes the whole transmission process through VXLAN, aiming at complex network conditions, such as the change of source node in intranet and NAT mapping and the change of transit POP public network IP, the method can support, and avoids communication interruption caused by various complex conditions.

The descending label thought of the segmented routing is introduced, a VXLAN forwarding table does not need to be inquired, the forwarding efficiency of the data packet is improved, the use of vni is reduced, and the risk that vni is exhausted is reduced. The whole network communication process is a virtualization channel, and network communication interruption caused by network condition change (NAT mapping change and transit public network IP change in the processes of intranet and network communication of edge nodes) can be avoided.
