Problems solved by technology

[0002] In the new delivery data center scenario, the service provider of the cloud platform will deploy the physical network of physical servers in the user's computer room, and deploy cloud products on these physical servers. In this way, the underlay (bottom layer) of the cloud platform The network will be exposed outside the boundaries of the service provider's network isolation and security operation and maintenance, and it will rely heavily on the user's management and protection methods, and the risk of attacking the cloud platform through the underlying network will rise sharply

Abstract

The embodiment of the invention discloses a data transmission method and device, a medium and a product. The method comprises the steps that a first data packet is sent to a destination port of a destination server for the first time; receiving a destination unreachable message sent by the destination server, wherein the destination unreachable message is used for indicating a client to initiate authentication; in response to receiving the destination unreachable message, an authentication data packet is generated and returned, and the authentication data packet carries authentication information; and re-sending the first data packet to the destination port of the destination server. According to the technical scheme, the security risk of the underlying network exposed surface in the delivery type data center can be reduced, and the cloud platform is protected.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a data transmission method, device, medium, and product. Background technique [0002] In the new delivery data center scenario, the service provider of the cloud platform will deploy physical servers, these physical networks, into the user's computer room, and deploy cloud products to these physical servers. In this way, the underlay (bottom layer) of the cloud platform The network will be exposed beyond the boundaries of the service provider's network isolation and security operation and maintenance, relying heavily on the user's management and protection methods, and the risk of attacking the cloud platform through the underlying network increases sharply. The east-west and north-south communications of the cloud platform are exposed on the underlying network, which can be subjected to network attacks such as network sniffing, packet hi...
