Abstract
The invention provides a method for NAT (network address translation) of self-adaptive access of an edge computing gateway, which belongs to the technical field of communication, wherein the edge computing gateway automatically performs source address conversion on a user data packet according to an IP address corresponding to a distributed URL (uniform resource locator) according to a configured URL distribution rule and automatically manages generation, use and extinction of the conversion; when the edge computing gateway sends data to the edge computing platform, the IP message is automatically subjected to address conversion according to the address of the analyzed URL, and details of the network do not need to be known.
Description
Technical Field
The invention relates to the technical field of communication, in particular to a NAT method for self-adaptive access of an edge computing gateway.
Background
At present, the edge computing gateway does not perform address transformation on a user IP message, a complex route needs to be configured on an edge computing platform, a fixed IP needs to be configured on the edge computing gateway, and a network is complex and difficult to maintain. If the edge computing gateway does address transformation to the user IP message, the transformed address and the target application server are in the same network segment, routing and fixed IP do not need to be configured, and the network is flat and convenient to maintain.
If the edge computing gateway manually configures the IP packet address translation, it needs to know which addresses on the network have been used and avoid the used addresses being assigned, and it needs to add manual intervention, which is inconvenient for automatic deployment. If the NAT method of the edge computing gateway self-adaptive access is used, manual intervention is reduced, and automatic deployment is facilitated.
Disclosure of Invention
In order to solve the technical problem, the invention provides a method for calculating NAT of gateway self-adaptive access by an edge.
When the edge computing gateway sends data to the edge computing platform, the address conversion is automatically carried out on the IP message according to the address of the analyzed URL, the URL analyzed data sent back by the public network is analyzed without knowing the details of the network, and the URL and the IP address after the URL is analyzed are recorded in the shunt gateway.
The technical scheme of the invention is as follows:
a method for an edge computing gateway to adaptively access NAT,
when the edge computing gateway sends data to the edge computing platform, the address of the IP message is automatically converted according to the address of the resolved URL.
Further, in the above-mentioned case,
and the edge computing gateway automatically performs source address conversion on the user data packet according to the configured URL distribution rule and the IP address corresponding to the distribution URL, and automatically manages the generation, use and extinction of the conversion.
Further, in the above-mentioned case,
and analyzing URL analysis data sent back by the public network, and recording the URL and the IP address of the URL after being analyzed in the shunting gateway.
A private protocol query request is sent to the edge computing platform for the IP address, asking for which addresses are unused.
The edge computing platform sends a private protocol reply to the edge computing gateway informing the edge computing gateway which addresses are not used, and the addresses are in the same network segment as the addresses of the edge computing platform.
The edge computing gateway distributes the unused address to the terminal for use, when the terminal sends data to the edge computing gateway, the source address is subjected to address conversion, and the converted address is the unused address informed by the previous edge computing platform.
At this time, the address converted by the terminal and the address of the edge computing platform are in the same network segment, the data sent back by the edge computing platform can be sent to the edge computing gateway without configuring a route, the edge computing gateway performs destination address conversion again, the converted address is the original address of the terminal, and the terminal receives the data and performs subsequent processing.
When the conversion address is exhausted, the corresponding relation between the conversion address and the terminal is deleted, and the corresponding relation between the conversion address and the terminal is reconfigured, so that the aim of recycling is fulfilled.
Further, in the above-mentioned case,
the edge computing platform is a closed network and does not interact with a public network.
And when the converted address is used up, the corresponding relation between all the converted addresses and the terminal is released, and the corresponding relation between the converted address and the terminal is reconfigured.
The invention has the advantages that
The edge computing gateway automatically allocates the address to be used, and the maintenance personnel can complete the deployment of the edge computing gateway without knowing the details of the network topology.
