Detailed Description
Global Load balancing (GSLB) is used for traffic allocation between servers in different regions in a wide area network to ensure access quality. In various implementation schemes of the GSLB, the scheme based on anycast can be suitable for all scenes, and the problems of stream switching and single-point performance bottleneck are avoided. Anycast, also known as Anycast, is a network addressing and routing strategy that can determine the destination of a packet according to the routing topology. In a practical application scenario, the ISP may determine a data center providing a service from a plurality of data centers by using a dynamic routing Protocol, such as Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP). In the related art, there is a problem of poor service quality.
Based on this, in various embodiments of the present application, a first electronic device in a first data center receives a first data packet sent by an ISP, determines a second data center with better service quality than the first data center if there is no connection between the first data center and a second electronic device, and forwards the first data packet to the second data center; and the second electronic equipment represents the electronic equipment corresponding to the source address of the first data packet. Compared with the scheme of the data center which determines to provide service by the ISP, the scheme is that the data center determines to provide the service by combining the service quality of each data center, in other words, the data center reschedules the data packet, forwards the data packet to the data center with better service quality, and the data center with better service quality provides service, so that the service quality is improved.
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a schematic implementation flowchart of a traffic distribution method according to an embodiment of the present application, which is applied to a first electronic device in a first data center, where the first electronic device includes, but is not limited to, an electronic device such as a server and a terminal. The method comprises the following steps:
step 101: and receiving a first data packet transmitted by the ISP.
Step 102: and under the condition that the first data center is not connected with the second electronic equipment, determining a second data center, and forwarding the first data packet to the second data center.
The second electronic equipment represents the electronic equipment corresponding to the source address of the first data packet; the second data center characterizes a data center having a quality of service that is better than the first data center.
In consideration of disaster recovery guarantee, service expansion or single-machine room capacity, a multi-active architecture can be adopted to provide business services, at least two data centers are deployed in the architecture, and a plurality of electronic devices are arranged in each data center. In order to access the business service, the user terminal sends a data packet to the ISP; and the ISP receives the data packet sent by the user terminal, calculates a first data center based on the routing protocol, and sends the data packet to the first data center.
In step 101, the first data center receives a first data packet sent by an ISP, and determines whether a connection exists between an electronic device of the first data center and a second electronic device, so as to obtain a determination result. The second electronic device represents an electronic device corresponding to the source address of the first packet, that is, a source electronic device of the first packet, which is usually a user terminal. The first electronic device may be an interface device in the first data center, and the flow allocation method according to the embodiment of the present application is implemented by configuring the setting component.
Here, the first electronic device may determine whether a connection exists between the electronic device of the first data center and the second electronic device according to the connection tracking record of the first data center. Specifically, if the connection tracking record of the first data center includes the second electronic device, it is determined that a connection exists between the first data center and the second electronic device; and if the connection tracking record of the first data center does not contain the second electronic equipment, determining that no connection exists between the first data center and the second electronic equipment.
In step 102, when the determination result indicates that there is no connection between the electronic device of the first data center and the second electronic device, based on the set policy, the first electronic device determines a data center in the first system where the first electronic device is located, and the data center provides a service for the second electronic device. Here, whether or not there is a connection with the second electronic device may be determined from the connection trace record of the first data center.
The setting policy includes at least one of: whether it is in a viable state; whether a connection exists with the user terminal; the load is high and low; the link distance is far and near. Generally, data centers that are alive, have connections to user terminals, are under lower load and/or have links closer to them, provide higher quality of service.
And when the determined data center is not the first data center, namely, a second data center superior to the first data center is determined, forwarding the first data packet to the second data center. In this way, compared with the scheme of the data center which determines to provide service by the ISP, the scheme is that the data center determines to provide the service by combining the service quality of each data center, in other words, the data center reschedules the data packet, forwards the data packet to the data center with better service quality, and the data center with better service quality provides service, thereby improving the service quality. In addition, the embodiment of the application can realize the flow distribution without changing the setting of the ISP, and can improve the service quality at low cost.
And when the determined data center is the first data center, the first electronic equipment receives the first data packet, and the first data center provides service for the user terminal.
As shown in fig. 2, a flow chart of an implementation of the traffic distribution method is shown, and as an embodiment of the present application, the method further includes:
step 201: and performing data interaction with a data center in the first system.
Wherein the data interaction is used to synchronize network information of the first system; the first system characterizes a system in which the first data center is located.
Through configuration of the setting component, the first electronic device of the first data center interacts data with other data centers in the first system to synchronize network information of the first system. In this way, the first data center can learn the real-time status of the data centers in the first system, thereby determining a second data center that is superior to the first data center.
As an embodiment of the present application, the network information of the first system includes at least one of:
a network topology of the first system;
a connection tracking record for a data center within the first system;
connection statistics of data centers within the first system;
load information for a data center within the first system;
heartbeat data packets of a data center within the first system.
The network topology of the first system may be used for link calculation, the connection tracking record and the connection statistical data of the data center may be used for determining whether a connection exists, the load information of the data center may be used for allocating the data center, and the heartbeat data packet may be used for determining whether the data center is in a survival state.
In practical applications, as shown in the schematic architecture diagram of fig. 3, a user sends a data packet to an ISP; the ISP calculates a first data center according to the routing topology and forwards a data packet to the first data center; the first data center receives the data packet, and the electronic equipment configured with the GSLB component judges to receive, discard or reschedule the data packet. When the reschedule data packet is determined, the electronic device of the first data center forwards the data packet to the electronic device of the second data center. Here, data interaction such as data synchronization and heartbeat detection exists between the data centers.
As an embodiment of the present application, the determining the second data center in step 102 includes:
determining a second data center based on the connection tracking record of the data center; wherein the content of the first and second substances,
the connection tracking record of the second data center contains the second electronic device.
Due to the change of the network state, the calculation result of the ISP route is possibly changed, and a subsequent data packet of one connection or session is sent to another data center which does not establish the connection.
The first electronic device judges whether a data center containing the second electronic device exists or not based on the connection trace record of the data center in the first system, and determines the data center containing the second electronic device as the second data center. The connection tracking record is used for tracking and recording the connection state, and can judge whether a connection/session relation exists between the data center and the second electronic equipment which sends the first data packet. In this way, the data center connected with the second electronic device is determined as the second data center, and the second data center provides service for the second electronic device, so that connection resetting caused by the fact that the data center does not have session information is avoided; the data center can also normally provide services under the conditions of network change and the like, so that the system can be generally suitable for various network environments, and the robustness of the system is improved.
As an embodiment of the present application, the determining the second data center in step 102 includes:
determining a second data center according to a load balancing strategy based on the load and/or the first distance corresponding to the data center; wherein, the first and the second end of the pipe are connected with each other,
the first distance characterizes a link distance of a data center to the second electronic device.
According to the load balancing strategy, the first electronic device determines a second data center providing service for the second electronic device based on the load of the data center in the first system and/or the link distance with the second electronic device. Here, the data center is determined according to the load balancing strategy, and the data center closest to the link distance can be determined as the second data center based on the link distance; determining the data center with the minimum load as a second data center according to the load; it is also possible to rely on both load and link distance. Generally, the lower the load and/or the closer the link is to the data center, the higher the quality of service provided.
As an embodiment of the present application, the method further comprises:
a configured load balancing policy is received.
The first electronic device receives a load balancing strategy configured by an operation and maintenance person through an interface, and determines a second data center according to the load balancing strategy configured by the operation and maintenance person. And the operation and maintenance personnel configure the load balancing strategy, so that the flexibility of service provision is improved.
As an embodiment of the present application, the determining the second data center in step 102 includes:
judging whether a connection tracking record containing a data center of the second electronic equipment exists or not to obtain a judgment result;
determining the data center with the connection tracking record containing the second electronic equipment as the second data center under the condition that the judgment result represents that the connection tracking record contains the data center of the second electronic equipment;
determining the second data center according to a load balancing strategy based on a load and/or a first distance corresponding to the data center under the condition that the judgment result represents that the connection tracking record does not exist in the data center containing the second electronic device; wherein the content of the first and second substances,
the first distance characterizes a link distance of a data center to the second electronic device.
The first electronic device judges whether the connection tracking record in the first system contains the data center of the second electronic device based on the connection tracking record of the data center in the first system.
If the connection tracking record in the first system includes the data center of the second electronic device, the first electronic device determines the data center as the second data center.
If the connection tracking record does not exist in the first system and the data center containing the second electronic device is not present in the first system, the first electronic device determines the second data center providing service for the second electronic device according to the load balancing strategy based on the load of the data center in the first system and/or the link distance between the first electronic device and the second electronic device.
In this embodiment of the present application, the first electronic device first determines a connection relationship between a data center in the first system and the second electronic device, determines a data center connected to the second electronic device as the second data center, and forwards a data packet to the second data center, so that connection reset caused by a change in an ISP routing calculation result can be avoided. Under the condition that a data center connected with the second electronic equipment does not exist in the first system, the first data packet is a data packet which is requested to be sent by the second electronic equipment for the first time; and the first electronic equipment determines a second data center with high service quality for the second electronic equipment based on the load of the data center in the first system and/or the link distance with the second electronic equipment, so that the service quality is improved.
The present application will be described in further detail with reference to the following application examples.
The currently popular GSLB implementations suffer from the following problems, respectively:
1) an intelligent DNS based scheme.
For example, in a multi-activity scenario, when a certain data center fails, even if the authoritative server is updated at the first time, the IP of the failed data center is not returned; but because of the client's DNS cache (e.g., browser, operating system), ISP DNS, or public DNS service, the request is still sent to the failed data center for a period of time (ranging from minutes to hours), resulting in a request failure.
2) An Anycast-based protocol.
The load strategy is inflexible and the load is less balanced. Because the dynamic routing protocol adopted by ISP allocation only considers the shortest link distance from the user to the data center; under a multi-activity scene, due to the fact that users in different regions are distributed unevenly, the data centers near the regions with excessive users are overloaded, while the data centers in other regions are idle, and the problem of unbalanced load exists.
The data packet may be sent to the wrong server. Since the BGP of the ISP uses a dynamic routing protocol (e.g., OSPF or BGP), the route may be recalculated in the process of one connection, resulting in a change in the route, and a subsequent packet on the same TCP connection is sent to a different server, and since the connection or session does not exist on the new server, the established TCP connection is erroneously reset, the message cannot be normally sent, and a normal session cannot be performed.
OSPF is a routing protocol based on IP protocol, and is an IGP protocol widely used in large and medium-sized networks. OSPF is an implementation of a link-state routing protocol, operating within an autonomous system.
BGP, is a decentralized autonomous routing protocol at the core of the internet. It achieves reachability between Autonomous Systems (AS) by maintaining an IP routing table or "prefix" table, belonging to a vector routing protocol.
3) A scheme based on reverse proxy and triangle transmission mode Direct Routing.
There is a single point performance bottleneck problem.
4) Based on HTTP redirection and a scheme of uniformly scheduling service layers.
The usage scenario is limited. For example, HTTP redirection only applies to the HTTP protocol; the unified scheduling service layer needs the participation of the client, and basically excludes the browser.
Based on this, the application embodiment improves the defects of the existing scheme, optimizes on the basis of Anycast, realizes Stabilized Anycast, and proposes a brand-new GSLB implementation scheme, as shown in FIG. 4. The data packets are rescheduled based on factors such as the survival condition of each data center, connection tracking, actual load, distance from the user terminal, scheduling strategy configured by the user and the like, so that the relative balance of the load of each data center can be ensured, the data packets can be effectively prevented from being sent to wrong service terminals, and finally the access quality of the user is ensured.
The following describes the key processes and algorithms involved in the present solution with reference to fig. 5:
1) data synchronization and heartbeat detection.
As shown in the overall architecture, the GSLB implementation scheme is distributed, and each data center is provided with a GSLB component. As shown in fig. 6, the GSLB components are peer-to-peer, and perform data synchronization and heartbeat detection with each other:
and data synchronization is realized, so that each GSLB component has a global view in the system, and more balanced load scheduling is realized. The synchronized data includes connection trace records connection tracking, connection statistics, virtual service load, etc. Some delay is allowed in the synchronization process, and the influence is small.
Heartbeat detection can be used to detect whether GSLB components or data centers fail, so that these failed data centers can be skipped when rescheduling.
2) And (5) rescheduling.
When a GSLB component receives a client side packet, if the packet does not establish a connection or session with itself, or has other data center with better quality of service, the GSLB component reschedules the packet and forwards the packet to other data center.
Here, fig. 7 shows a rescheduling algorithm flow.
3) And (6) forwarding the data.
Each GSLB component is preferably additionally configured with an internal communication port on the basis of configuring the VIP network port, and the internal communication port is used for data forwarding, so that the throughput of the whole system can be improved.
As shown in fig. 8, currently, packet forwarding may be implemented based on a tunneling technique, for example, using GRE (Generic Routing Encapsulation), VXLAN (Virtual eXtensible Local Area Network), or other protocols.
The application embodiment provides a GSLB implementation scheme based on Anycast, and effectively solves the problems of the current mainstream scheme, such as inflexible load strategy, unbalanced load, connection reset caused by mistaken sending of data packets and the like, of the Anycast scheme.
Here, the architecture of the present application embodiment is tested, and GSLB components are deployed in 2 data centers. Respectively carrying out continuous pressure tests on 2 data centers, wherein the concurrent request number of a first data center is 200, and the concurrent request number of a second data center is 100; it can be observed that the load of the backend services of 2 data centers is substantially even. Establishing a TCP connection for a back-end service of a first data center, and continuously sending a message; and constructing a scene of BGP route change, so that the message is sent to the second data center, and the situation that the message can still be successfully sent and the connection cannot be reset by the server can be observed.
