Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that these descriptions are illustrative only and are not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.
Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In the process of implementing the present disclosure, it is found that a cross-cluster request service can be implemented between multiple clusters in different areas through a centralized gateway node, but implementing the cross-cluster request service through the centralized gateway node requires manual deployment of service information of the multiple clusters at the centralized gateway node, which results in a relatively high intrusion of service codes of the gateway node and relatively high requirements on network deployment and quality.
RPC (Remote Procedure Call Protocol), a Protocol that requests services from Remote computer programs over a network without knowledge of the underlying network technology. An RPC request calls a function or method (which may be collectively referred to as a service) on one machine (client) by means of parameter passing from another machine (server) and gets the returned result. Traditional RPC request calls are typically made within a single cluster, and RPC request calls are less capable of serving services from clusters in multiple different regions. When the cross-cluster RPC call is solved, the RPC client side needs to firstly perceive the difference of network deployment, and different privatization implementation modes are respectively used for independent processing aiming at the cross-gateway call. Service deployment differences can result in significant intrusiveness in the business code.
The embodiment of the disclosure provides a request response method and a request response device, which are applied to an access gateway, wherein the access gateway is used for processing the affairs of accessing an access device to a first service cluster, and the method comprises the following steps: obtaining a remote procedure call request from an access device, wherein the remote procedure call request is used for requesting a target service; in response to the remote procedure call request, establishing a communication link between the access gateway and a service gateway of a second service cluster in the case that the target service is provided for the second service cluster; and transmitting the remote procedure call request to the service gateway over the communication link such that the second service cluster responds to the remote procedure call request.
Fig. 1 schematically illustrates an exemplary system architecture to which the request response method and apparatus may be applied, according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, a system architecture 100 according to this embodiment may include an access device 110, a first service cluster 120, a second service cluster 130, and a third service cluster 140. The first service cluster 120 includes an access gateway 121 and a service node 122. The second service cluster 130 includes an access gateway 131 and a service node 132. A third service cluster 140 includes an access gateway 141 and a service node 142.
Communication between access device 110, first service cluster 120, second service cluster 130, and third service cluster 140 is based on access gateway 121, access gateway 131, and access gateway 141. A network medium is provided with communication links between access device 110, access gateway 121, access gateway 131, and access gateway 141. The network medium providing the communication link may include various connection types, such as wired and/or wireless communication links, and so forth.
A user may use access device 110 to send a request to any of access gateway 121, access gateway 131, and access gateway 141 over a network medium. The access device 110 may determine the access gateway matching it through the routing policy, and after determining the access gateway of the access device 110, the access gateways of other service clusters actually become the service gateways. For example, the access gateway of the access device 110 is the access gateway 121 in the first service cluster 120, and at this time, the access gateway 131 in the second service cluster 130 and the access gateway 141 in the third service cluster 140 become service gateways of the access device 110.
Because each service cluster can comprise the respective access gateway, each access gateway can process the access transaction of the access device, and the application layer of the remote procedure call request does not need to sense the difference of cluster nodes deployed by the service, the technical effect of decentralized response is achieved, and the network deployment and quality requirements are reduced.
The access device 110 may be a variety of electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablets, laptop portable computers, desktop computers, and the like. Various messenger client applications, such as a shopping-like application, a web browser application, a search-like application, an instant messenger, a mailbox client, and/or social platform software, etc. (to name a few examples), may be installed on access device 110.
It should be noted that the request response method provided by the embodiment of the present disclosure may be generally performed by any one of access gateway 121, access gateway 131, and access gateway 141. Accordingly, the request response device provided by the embodiment of the present disclosure may be generally disposed in access gateway 121, access gateway 131, and access gateway 141.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Fig. 2 schematically shows a flow chart of a request response method according to an embodiment of the present disclosure.
The request response method is applied to an access gateway, where the access gateway is configured to process a transaction of an access device accessing a first service cluster, as shown in fig. 2, and the method includes operations S201 to S203.
In operation S201, a remote procedure call request from an access device is obtained, wherein the remote procedure call request is used to request a target service.
In operation S202, in response to the remote procedure call request, in case the target service is provided for the second service cluster, a communication link is established between the access gateway and a service gateway of the second service cluster.
In operation S203, a remote procedure call request is transmitted to the service gateway over the communication link so that the second service cluster responds to the remote procedure call request.
According to an embodiment of the present disclosure, a target service is determined according to a remote procedure call request initiated by an access device. The user may enter the service that needs to be requested on the access device.
According to an embodiment of the disclosure, in response to a remote procedure call request, in a case where a target service is provided for a first service cluster, the remote procedure call request may be sent by an access gateway to a service node of the first service cluster for response.
According to an embodiment of the disclosure, the first service cluster and the second service cluster may be distributed clusters, and may be deployed in different areas.
According to an embodiment of the present disclosure, the first service cluster and the second service cluster may be service clusters having a relationship between a higher level and a lower level, for example, the first service cluster is a service cluster set inside a certain enterprise head office, and the second service cluster is a service cluster set inside a branch office subordinate to the enterprise.
According to an embodiment of the present disclosure, it should be noted that, although only the service that the target service may provide for the second service cluster is described above, a person skilled in the art may understand that the target service may also be a service that the third service cluster, the fourth service cluster, or the fifth service cluster provides. The description of the embodiment of the present disclosure in operation S202 is only for expressing the case where the remote procedure call request is for requesting a target service across the cluster, and should not unduly limit the scope of the present disclosure.
According to an embodiment of the present disclosure, the communication link between the access gateway and the serving gateway is equivalent to a virtual private communication link established between the access device and the serving gateway, a "link" provided by the protocol data stream. It provides basic functionality like "TCP" communication, where the protocol is roughly divided into two layers: a link data reliability protocol and a link data processing protocol. Wherein the link data processing protocol can be further divided into a control plane and a data plane. The control plane mainly comprises a connection state maintenance message, including establishment and closing, abnormal release and the like; the data plane is mainly related service data.
According to the embodiment of the disclosure, since the communication link between the access gateway and the service gateway is equivalent to a virtual private communication link established between the access device and the service gateway, for the upper layer application, the access client application layer does not need to sense the difference of cluster nodes of service deployment, and is equivalent to directly performing communication between the access device and the service gateway, thereby providing a uniform RPC calling framework for the upper layer application.
According to the embodiment of the disclosure, the remote procedure call request is responded based on the access gateway, cross-cluster call is realized by using the communication link between the access gateway of the first service cluster and the service gateway of the second service cluster, each service cluster can comprise the respective access gateway, each access gateway can process the access transaction of the access device, and the application layer of the remote procedure call request does not need to sense the difference of cluster nodes of service deployment, so that the technical problem that the traditional cross-cluster call of the remote procedure call request needs to search a service access point on a centralized cluster in the related art is solved, the technical effect of decentralized response is achieved, and the network deployment and quality requirements are reduced.
The method shown in fig. 2 is further described with reference to fig. 3-5 in conjunction with specific embodiments.
According to an embodiment of the disclosure, establishing a communication link between the access gateway and a service gateway of the second service cluster comprises: searching a network address of a service gateway of a second service cluster; sending a link establishment request carrying a network address to the relay gateway so that the relay gateway sends the link establishment request to the service gateway; receiving a link establishment response from the relay gateway, wherein the link establishment response is sent by the serving gateway to the relay gateway; and establishing a communication link between the access gateway and the serving gateway based on the link establishment response.
Figure 3 schematically illustrates a flow chart for establishing a communication link between an access gateway and a serving gateway according to an embodiment of the disclosure.
As shown in fig. 3, establishing a communication link between an access gateway and a serving gateway includes operations S301-S306.
In operation S301, an RPC client (i.e., an access device) establishes a request for establishment of a communication link to a target cluster. The target cluster may be a second service cluster as described above.
In operation S302, the access gateway performs routing lookup for the cluster, finds a service gateway of the target cluster, and performs routing lookup for the service gateway.
In operation S303, the request packet is transmitted to the trunking gateway.
In operation S304, the trunking gateway forwards the request packet to the serving gateway. According to an embodiment of the disclosure, the relay gateway may be a gateway in the first service cluster, and since the data of the remote procedure call request is not processed in the first service cluster, the relay gateway may serve as a data forwarding gateway.
In operation S305, the serving gateway performs a communication link establishment process and returns a response packet, i.e., a link establishment response, to the relay gateway.
In operation S306, the relay gateway returns a link establishment response in the form of a data packet according to the original routing path, so that the access gateway can establish a communication link between the access gateway and the serving gateway based on the link establishment response.
According to the embodiment of the disclosure, after the communication link is established, a remote service call can be made between the RPC client and the RPC server.
According to an embodiment of the present disclosure, in responding to a remote procedure call request, it may be determined by which service cluster the target service of the remote procedure call request is provided.
According to the embodiment of the disclosure, the remote procedure call request can be analyzed; and under the condition that the identification information of the second service cluster is carried in the remote process call request obtained through analysis, determining that the target service is provided for the second service cluster.
According to the embodiment of the disclosure, a service cluster for providing a target service may also be determined from a service list, where the service list includes mapping relationships between different services and the service cluster. For example, the service list includes a plurality of records of service 1 provided by the first service cluster, service 2 provided by the second service cluster, and service 3 provided by the third service cluster.
Fig. 4 schematically illustrates a schematic diagram of a multi-level gateway according to an embodiment of the present disclosure.
As shown in fig. 4, the multi-level gateways include gateways 401 to 405, where a gateway at the upper level of the gateway 401 is a gateway 402, a gateway at the upper level of the gateway 402 is a gateway 403, a gateway at the upper level of the gateway 405 is a gateway 404, and a gateway at the upper level of the gateway 404 is a gateway 403.
In an actual enterprise private deployment, a multi-cluster tree organization network structure as shown in fig. 4 may be used, according to an embodiment of the present disclosure. The networking requirement for the gateway may be a learning capability for the multi-cluster tree route. Each tree superior typically obtains more routing information than the subordinate gateways. The gateways 403 at the top level have full network routing information. Once networking is completed, any gateway can communicate with another gateway by using a communication link.
According to the embodiment of the disclosure, each gateway can belong to one service cluster, and networking is performed among a plurality of gateways, that is, networking is realized among a plurality of service clusters.
According to the embodiment of the disclosure, networking is performed among a plurality of service clusters, wherein the plurality of service clusters comprise a first service cluster and a second service cluster; and sending the routing information of the access gateway to the upper-level gateway according to the routing information of the upper-level gateway configured in the access gateway of the first service cluster, so that the upper-level gateway can learn the routing according to the routing information of the access gateway and the routing information of the upper-level gateway.
According to the embodiment of the disclosure, the access gateway has autonomous learning capability of global network topology, and realizes the ad hoc network of the global network. According to an embodiment of the present disclosure, the upper level gateway includes, but is not limited to, a service gateway and/or a relay gateway in other service clusters. According to the embodiment of the present disclosure, the upper level gateway may also include a relay gateway and the like belonging to the same service cluster as the access gateway.
According to embodiments of the present disclosure, service publishing for a service cluster relies on having the capability of global data synchronization between gateways. For data published on one access gateway, each item of data can be described by information such as { data located gateway, data publishing gateway, data version } and the like. The service synchronization process is the process of data transmission and reception between the upper and lower levels of each layer of the gateway. According to the embodiment of the disclosure, the consistency guarantee of the data can be carried out through the data version number constraint. Because the cluster service has a relatively low change frequency, the delay of the network-wide consistency diffusion can be ignored.
According to the embodiment of the disclosure, an access gateway may load a service list of a first service cluster, where the service list includes identification information of the first service cluster and services that the first service cluster can provide; the service list of the first service cluster is then synchronized to the service gateway of the second service cluster.
According to the embodiment of the disclosure, the access gateway may further receive a service list from the second service cluster, where the service list of the second service cluster includes the identification information of the second service cluster and the services that the second service cluster can provide.
According to the embodiment of the disclosure, on the basis of the service cluster synchronization information of the global network, the addressing of any cluster can be realized through the communication link between the access gateway and the service gateway, and further, the RPC data is transmitted under the whole network through the data forwarding capacity of the gateway to the communication link. For the service layer, any RPC call under the global network can be realized.
FIG. 5 schematically shows a flow diagram of cluster service synchronization according to an embodiment of the disclosure.
As shown in fig. 5, the cluster service synchronization method includes operations S501 to S506.
In operation S501, the access gateway loads the service list of the cluster itself.
In operation S502, it is determined whether the service list of the cluster itself changes, if yes, operation S503 is performed to perform a synchronization operation, otherwise, the synchronization operation is not performed. According to the embodiment of the disclosure, the service list of the cluster itself may be compared with the service list in the synchronization library, and if the service list is the same, no change is indicated, and if the service list is different, a change is indicated. The synchronization library comprises information such as service lists, synchronization time, data version numbers and the like of different clusters.
In operation S503, synchronization information is transmitted to the upper level gateway.
In operation S504, the upper level gateway may update the local service list according to the synchronization information.
In operation S505, when the previous-level gateway determines that the service list of the service cluster where the previous-level gateway is located has changed, the service list of the service cluster where the previous-level gateway is located may be sent to the access gateway as synchronization information.
The access gateway updates the changed service list according to the synchronization information in operation S506.
