Description
Technical Field
The invention relates to the field of cloud computing, in particular to a method for accessing a distributed bare metal server to a network and application thereof.
Background
In cloud computing systems, computing services are typically provided by virtual machines. In high performance computing scenarios, bare metal servers are typically used to improve computing performance subject to performance limitations of the virtual machines. The bare metal server is used as a supplement of the virtual machine, has the characteristics of high performance of the traditional physical server, high safety and reliability on the cloud, flexibility and quick distribution and the like, and is widely applied to key services of scenes such as databases, big data, containers, high-performance computing and AI. The bare metal server is generally deployed in a physical network, and the cloud computing system is responsible for life cycle management of the bare metal server and needs to be accessed to a virtual network of the cloud computing system.
The physical network of the bare metal server is usually a VLAN network, the network inside the cloud computing system is usually an overlay network, and at present, the VLAN network is usually accessed to the overlay network by using a tunnel encapsulation technology, such as VXLAN, GRE, MPLS, and the like. For example, (1) a centralized network node is used as a VXLAN gateway. And connecting the internal network of the cloud network and the bare metal physical network by using the general server and running a functional program with the virtual router. The virtual router has tunnel encapsulation and decapsulation capabilities and an ARP reply function. And the SDN controller maintains the mapping relation between the internal network and the physical network and issues the conversion rule to the virtual router. However, this method requires the use of additional server resources, and the centralized network node is prone to failure point concentration, failure and performance bottleneck. (2) Distributed computing nodes are used as access points. And completing the access of the bare metal server network to the cloud network by utilizing the function of the virtual router on the computing node. However, the method does not perform traffic isolation according to network granularity on the accessed network, the traffic of the bare metal network may be concentrated on a certain node, which results in the decrease of traffic processing capability, and there is no mechanism to process the fast switching of traffic channels when the node is down or the program is abnormal, which makes the reliability difficult to guarantee. (3) Hardware devices that support VXLAN gateway functionality are used. A gateway device using a dedicated VXLAN function, for example, uses a VXLAN switch to connect a bare metal server network to a cloud network. And the controller transmits the mapping configuration of the VXLAN and the VLAN to the gateway equipment. The gateway device acts as an endpoint of a tunnel and is in tunnel communication with the virtual machine. The method needs to use additional special gateway equipment, the SDN controller needs to have the capability of controlling the gateway equipment, and the type selection of the gateway equipment is limited.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 4, a method for accessing a network by a distributed bare metal server according to an embodiment of the present invention is described, which includes the following steps.
In step S101, an endpoint serving as a bare metal access network port is determined according to the states of all bare metal access endpoints and the number of logical interfaces, and a logical interface is created at the endpoint.
For VXLAN-type internal networks, VNI (VXLAN Network Identifier) is used for unique identification. The bare metal server is accessed in the VXLAN internal network, and the mapping relation between VXLAN and VLAN needs to be specified. And planning a VLAN pool of the bare metal physical network when the bare metal service is deployed. Unused VLANs are allocated in the VLAN pool before the VXLAN internal network accesses the bare metal server. And the SDN controller stores the mapping relation between the VXLAN and the VLAN in a database. Planning a plurality of computing nodes as access endpoints of the bare metal network, and planning a physical network port at each access endpoint as an access network port of the bare metal network. The SDN control selects an access endpoint to create a logic interface, and one logic interface corresponds to a bare metal physical network.
In order to uniformly distribute the traffic of the bare metal server network to each bare metal access endpoint, a scheduling algorithm with the minimum load is adopted when a logical interface is created.
Specifically, the minimum number of logical interfaces min _ li _ num is set to 0xFFFF, the bare metal access network port min _ pi is set to null, and the access endpoint of the bare metal server is traversed. Judging whether the state of the access endpoint is normal or not, if not, directly and continuously traversing the access endpoint of the next bare metal server; if yes, acquiring the number of logical interfaces of the current access endpoint, if the number of logical interfaces current _ li _ num of the current access endpoint is smaller than the minimum number of logical interfaces min _ li _ num, setting the minimum number of logical interfaces as the number of logical interfaces of the bare metal access endpoint (min _ li _ num is current _ li _ num), and setting the bare metal access network port as the physical network port of the current bare metal server access endpoint. And continuously traversing the access end point of the next bare metal server until all the access end points of all the bare metal servers are completely traversed, and creating a logic interface on the end point which is finally set as the bare metal access network port.
In step S102, a virtual machine interface is created in the SDN, and the virtual machine interface is added to the logical interface.
As shown in fig. 2, each virtual network accessing a bare metal server selects a compute node running a virtual router on which to create a logical interface. For each access network port of the bare metal server, a VMI (Virtual Machine Interface) is created for each bare metal server access network port in the logical Interface. The MAC address of the VMI is the MAC address of the bare metal server access portal, and the IP address is allocated by the SDN in the corresponding virtual network.
Example 2
As shown in fig. 5 to 7, a method for accessing a network by a distributed bare metal server in one embodiment of the present invention is described, which includes the following steps.
In step S201, an endpoint serving as a bare metal access network port is determined according to the states of all bare metal access endpoints and the number of logical interfaces, and a logical interface is created at the endpoint.
For VXLAN-type internal networks, VNI (VXLAN Network Identifier ) is used for unique identification. The bare metal server is accessed in the VXLAN internal network, and the mapping relation between VXLAN and VLAN needs to be specified. And planning a VLAN pool of the bare metal physical network when the bare metal service is deployed. Unused VLANs are allocated in a VLAN pool before the VXLAN internal network accesses the bare metal server. And the SDN controller stores the mapping relation between the VXLAN and the VLAN in a database. And planning a plurality of computing nodes as access endpoints of the bare metal network, and planning a physical network port at each access endpoint as an access network port of the bare metal network. The SDN control selects an access endpoint to create a logic interface, and one logic interface corresponds to a bare metal physical network.
In order to uniformly distribute the traffic of the bare metal server network to each bare metal access endpoint, a scheduling algorithm with the minimum load is adopted when a logical interface is created.
Specifically, the minimum number of logical interfaces min _ li _ num is set to 0xFFFF, the bare metal access network port min _ pi is set to null, and the access endpoint of the bare metal server is traversed. Judging whether the state of the access endpoint is normal or not, if not, directly and continuously traversing the access endpoint of the next bare metal server; if yes, acquiring the number of logical interfaces of the current access endpoint, if the number of logical interfaces current _ li _ num of the current access endpoint is smaller than the minimum number of logical interfaces min _ li _ num, setting the minimum number of logical interfaces as the number of logical interfaces of the bare metal access endpoint (min _ li _ num is current _ li _ num), and setting the bare metal access network port as the physical network port of the current bare metal server access endpoint. And continuously traversing the access end point of the next bare metal server until all the access end points of all the bare metal servers are completely traversed, and creating a logic interface on the end point which is finally set as the bare metal access network port.
In step S202, a virtual machine interface is created in the SDN, and the virtual machine interface is added to the logical interface.
Each virtual network accessing the bare metal server selects a compute node running a virtual router on which to create a logical interface. For each access network port of the bare metal server, a VMI (Virtual Machine Interface) is created for each bare metal server access network port in the logical Interface. The MAC address of the VMI is the MAC address of the bare metal server access portal, and the IP address is allocated by the SDN in the corresponding virtual network.
In step S203, when the access port of the bare metal network is down or the virtual router agent state is abnormal, the access endpoint in the normal state is selected to reconstruct the logical interface, and the access port of the bare metal network is moved to the reconstructed logical interface.
When the bare metal service is deployed, a plurality of computing nodes running the virtual router are selected as access endpoints of the bare metal server, so that higher bandwidth and network reliability are provided. And when the system detects that the network port of the access endpoint of the bare metal server is down or the proxy state of the virtual router is abnormal, performing fault switching of the access endpoint.
Specifically, according to a scheduling algorithm with the minimum load, a computing node in a normal state is selected, a logic interface is rebuilt, and an access network port of the bare metal server is migrated to the newly-built logic interface from the logic interface on the fault endpoint. For a physical network, a gratuitous ARP needs to be sent from a virtual machine in the virtual network and the MAC address table on the switch is refreshed.
In step S204, when the failed access endpoint returns to normal, a part of the logical interfaces on the access endpoint with more access bare metal servers is automatically migrated to the access endpoint with less bare metal servers according to the load of the access endpoint.
The scenarios requiring fault recovery are divided into two categories: one is that when the access endpoint with a fault recovers to normal, the traffic recovery, i.e. fault recovery, is required to be performed, so as to utilize the forwarding capability of the original access endpoint to improve the processing capability of the network traffic; another scenario is that the number of bare metal servers in different networks is different, and the traffic is also different, and balancing needs to be performed according to the number of bare metal servers on each access endpoint.
The failure recovery schemes are also divided into two types: one is migration by an administrator from a certain logical interface of a specified access endpoint to a specified new access port through a system-provided API; one is that the system automatically migrates a part of the logical interfaces on the end points with more access bare metal servers to the end points with less bare metal servers according to the load of the access end points, so as to achieve a new balance.
Specifically, the average number avg _ bm _ num of bare metal servers at the access endpoint of each bare metal server is calculated, the access endpoint of the bare metal server is traversed, the number of bare metal servers at the access endpoint is calculated, and if the number of bare metal servers at the access endpoint is greater than the average number avg _ bm _ num of bare metal servers, the access endpoint of the next bare metal server is directly traversed; if the number of the bare metal servers of the access endpoint is less than the average number of the bare metal servers avg _ bm _ num, calculating a difference delta between the number of the access endpoint and the average number of the bare metal servers, traversing the endpoints of which the number of the bare metal servers of the access endpoint is greater than the average number of the bare metal servers, and migrating redundant logic interfaces to the access endpoint from the endpoints, wherein the number of the bare metal servers migrated to the logic interface of the access endpoint is less than the difference.
Referring to fig. 8, an apparatus for accessing a network by a distributed bare metal server according to an embodiment of the present invention is described.
