Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the edge cloud packet forwarding method and system, the network packet forwarding method and system of the present invention are further described in detail with reference to the accompanying drawings and the detailed description.
The invention provides a method for forwarding edge cloud messages, which adopts an SDN networking mode, and flexibly configures the flow of edge equipment in an edge cloud environment based on a control and forwarding separation mode of an SDN controller and a flexible proxy of a white box switch node, so that network forwarding of transparent proxies of network messages based on application is realized, cooperation is performed between a dispersed edge cloud and a centralized cloud computing center, and the network experience of users is greatly improved.
The invention provides a marginal cloud message forwarding method and a message forwarding system, which are provided aiming at marginal cloud scenes.
As an aspect of the present invention, a flowchart of the edge cloud packet forwarding method shown in fig. 1 and an implementation schematic diagram of the edge cloud packet forwarding method shown in fig. 2 are provided, where the method includes:
step S0): presetting an edge forwarding table, wherein the edge forwarding table at least comprises five fields of a source IP, a destination forwarding IP, a destination port and a destination forwarding port.
Each table entry in the edge forwarding table is composed of five fields, and one table entry represents one type of application. The structure of the edge forwarding table is fixed, and the values of the inner fields are set by an administrator. The network administrator only needs to maintain the edge forwarding table at the controller end, and the flow forwarding of the edge device based on the application can be realized.
When a service provider in the edge cloud provides a service in the replaceable centralized cloud data center, an IP address of the service provider is used as a destination to forward an IP, a port number of the service provider is used as a destination forwarding port, an IP of the service provider in the original centralized cloud data center is used as a destination IP, a port number of the service provider in the original centralized cloud data center is used as a destination port, and an IP address of a service requester close to one side of the edge cloud is used as a source IP, so that an edge forwarding table entry in the controller 3 is formed.
Step S1): the edge device 1 initiates an application request network packet.
The edge device 1 initiates an application request network packet, for example, a service requester near the edge cloud sends a service request packet, the application request network packet includes a destination IP and a destination port, a forwarding content provider host can be obtained based on the destination IP, and a requested content service can be obtained based on the destination port, thereby obtaining different applications.
Step S2): and the switch 2 matches the flow table after receiving the application request network message and uploads the message to the controller 3.
After receiving the application request network packet of the edge device 1, the switch 2 matches the application request network packet with the initial flow table, and uploads the initial flow table to the controller 3.
Step S3): the controller 3 performs message analysis and then matches the source IP, the destination IP and the destination port in the edge forwarding table.
According to the edge cloud message forwarding method, message forwarding is achieved by using a white box switch at a user access side, and network message forwarding logic based on application is formulated through controller software according to requirements at a control layer, so that network messages of edge equipment 1 are forwarded to corresponding service nodes without sensing according to management logic, and transparent proxy is achieved. In fig. 2, the switch 2 is a white box switch, that is, the switch 2 is an SDN switch; the controller 3 is configured as an SDN controller. The SDN switch decouples the hardware and the software of the switch, and a user can match third-party operating system software into the hardware of the switch according to needs, so that a manager can flexibly design and configure a network.
The SDN controller analyzes the application request network message, at the moment, the SDN controller matches the corresponding field content obtained by analysis with the corresponding field content in an edge forwarding table in the SDN controller, the analyzed application request network message is matched with the edge forwarding table, and if the matching is successful, a flow table of corresponding logic is issued to an SDN switch.
In the edge cloud message forwarding method of the embodiment, the message forwarding is realized by using the SDN switch at the user access side, and an administrator can set and maintain the edge forwarding table through the SDN controller. Each table entry is considered as an application according to an edge forwarding table in the controller 3, where the edge forwarding table at least includes five key fields of a source IP, a destination forwarding IP, a destination port, and a destination forwarding port. The controller software is an application program, and the edge forwarding table is a data structure used for completing the logic. Application differentiation can be performed according to the edge forwarding table, and traffic differentiation is performed based on different applications.
Step S4): if the matching is successful, the destination IP of the network message in the flow table is modified into the corresponding destination forwarding IP in the edge forwarding table, the destination port in the flow table is modified into the destination forwarding port, and the network message and the corresponding updated flow table are issued to the switch 2.
The process of the controller 3 matching the edge forwarding table and updating the flow table specifically includes:
if the matching is not successful, it is indicated that the service provider for the application is not deployed in the edge cloud environment, and at this time, the SDN controller sends a message to the SDN switch through a packet _ out message, and issues a flow table, so that the message is sent out by the SDN switch from a port connected to the centralized cloud data center;
if the matching is successful, it indicates that the service provider for the application has been deployed in the edge cloud environment, and at this time, the SDN controller sends the packet to the SDN switch through a packet _ out message, updates and issues the flow table, and performs step S5).
The SDN switch matches the message arriving at the SDN switch according to the updated flow table issued by the controller 3, the matching content is the source IP, the target IP and the target port of the message, the field resetting action is executed on the successfully matched message, the target IP of the message is changed into the target forwarding IP, and the target port is changed into the target forwarding port.
Step S5): and the switch 2 forwards the received network message to the edge cloud according to the updated flow table.
And forwarding the message from a port of the SDN switch connected with the edge cloud environment according to the purpose forwarding IP in the updated flow table by the SDN switch.
Step S6): and after receiving the request network message, the edge cloud node performs tasks such as calculation and the like, returns a response message, and forwards the response message to the switch 2 through the network.
After receiving a service request message, a service provider in the edge cloud environment confirms that a target IP (Internet protocol) of the request message is consistent with a target port and a service provider, and the service provider determines that the request message is sent to the service provider, responds to the request message, generates a response message and sends the response message to an SDN (software defined network) switch connected with the response message.
Step S7): the switch 2 updates the source IP address of the response packet to the destination IP in step S4), and updates the source port number to the destination port in step S4), according to the updated flow table issued by the controller 3, and forwards the response packet from the response port.
And the SDN switch receives a response message, wherein the destination IP is the IP of the service requester (namely the source IP in the edge forwarding table). The source IP and the source port number are both the IP of the service provider in the edge cloud and the port number of the application (i.e. the destination forwarding IP and the destination forwarding port in the edge forwarding table). And the SDN switch matches the destination IP, the source IP and the source port of the message according to the flow table, and successfully performs field resetting action on the response message, wherein the action changes the source IP in the response message into the destination IP in the corresponding edge forwarding table and changes the source port into the destination port in the corresponding edge forwarding table.
The SDN switch forwards the response message out of the port of the connection service requester. After the service requester receives the message, the source IP and the source port of the response message are consistent with the destination IP and the destination port of the request message, and then the service requester confirms that the response is received.
According to the edge cloud message forwarding method and the edge cloud message forwarding system, the request message is forwarded to the edge cloud environment close to the service requester, so that the bandwidth and the time delay are greatly improved (a centralized supermarket in the whole city and a supermarket distributed type analogy to all cells in the whole city can be achieved).
The edge cloud message forwarding method and the edge cloud message forwarding system set an SDN environment and configure control logic on the controller. In the prior art, the processing logic on the forwarding device occupies the resources of the forwarding device; the forwarding device in the mode of the invention only needs to forward the message according to the flow table. In addition, in the prior art, forwarding is distinguished according to domain names rather than according to applications, and granularity is very coarse; the mode of the invention distinguishes the application for forwarding, and the granularity is fine.
Therefore, the edge cloud message forwarding method and the edge cloud message forwarding system of the invention:
on one hand, the SDN technology is utilized to carry out edge cloud forwarding for application network messages, and since the response messages obtained by the service requesters are considered to be sent from service providers in the centralized cloud computing center and actually sent from the service providers in the edge cloud computing, transparent proxy of the target IP and the target port of the edge device is realized, and the management efficiency is improved;
on the other hand, based on the proxy mode of the IP + port, processing logic is centralized in the controller through an SDN mode, the processing logic is dispersed based on different types of applications, a DNS proxy mode is replaced, flow distinguishing can be carried out on different applications of edge equipment, flow scheduling based on the applications is achieved, domain name conversion needs to be carried out in a DNS mode in the existing distributed architecture cloud computing environment, and bandwidth and time delay are greatly improved.
As another aspect of the present invention, the network packet forwarding method and the network packet forwarding system provided by the present invention include a centralized cloud computing center and an edge cloud, and based on the edge cloud packet forwarding method and the corresponding network packet forwarding system, the present forwarding of a network packet is implemented, and a manner of dispersing a data center into a region relatively close to a user is implemented, so that the edge cloud and the centralized cloud computing center cooperate, and bandwidth and delay are greatly improved.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
