The application relates to a lightweight IPv4 / IPv6 translation method and device, which comprises the following steps: starting an IPv4 / IPv6 translation instance in a default VRF routing table on an IPv4 / IPv6 translation device, and creating two virtual ports; creating a user VRF routing table for each user on the IPv4 / IPv6 translation device; configuring corresponding translation rules according to the translation requirements of the users; connecting each user VRF routing table and the translation rules in a preset mode; when an IPv4 message to be translated or an IPv6 message to be translated enters the IPv4 / IPv6 translation device, matching a pre-configured mark rule, and after routing and forwarding in the corresponding user VRF routing table, translating the IPv4 message to be translated or the IPv6 message to be translated into a corresponding IPv6 message or IPv4 message by using the corresponding translation rules; and receiving the translated IPv6 message or IPv4 message by using the corresponding virtual port to perform routing and forwarding. The method can realize routing and IPv4 / IPv6 translation isolation for multiple slices / users on the basis of only configuring one IPv4 / IPv6 translation instance, and solves the limitations of traditional VRF and traditional IPv4 / IPv6 translation.

Techniques are disclosed for establishing a distributed virtual private network within a virtual bootstrap environment. A distributed computing system can generate a virtual cloud network in a data center of a host region. The virtual cloud network can include a plurality of host instances, including an instance hosting a virtual private network router. A second instance can provide a secondary network address to the virtual private network router. A third instance can send a request addressed to the secondary network address. The virtual cloud network may route the request to the virtual private network router according to a default route of a routing table. The request may then be forwarded by the virtual private network router to the secondary address using a networking tunnel established between the first instance and the second instance.

The invention discloses a cross-domain relay selection and routing forwarding method for a double-layer low-orbit constellation, which comprises the following steps of: constructing a resident relay satellite cluster, and strictly isolating inter-domain link state change signaling caused by high-speed movement of satellites in the cluster, thereby avoiding invalid topology perception of nodes of the whole network, and improving the reliability of the relay selection and routing forwarding. And the cross-domain routing signaling overhead and the convergence time are greatly reduced. On the basis, satellites in the cluster serve as cross-domain relay nodes, cross-domain routing forwarding is conducted on double-layer satellite network cross-domain routing through the resident relay satellite cluster, nodes outside the cluster can transmit cross-domain traffic to the relay cluster of the domain only through default routing, an on-satellite routing decision-making mechanism is greatly simplified, and the routing efficiency is improved. And the reliability and efficiency of whole network communication are improved.

The application discloses a method, device and network equipment for transmitting data, relates to the field of communication, and solves the problem of how to reduce resource consumption and storage pressure of a user-side edge node. The method comprises the following steps: a third network equipment sends a first route to a first network equipment according to a first mode neighbor of the third network equipment or according to a request received from the first network equipment. The first network equipment forwards a packet to a second user-side equipment connected with a second network equipment according to the first route. The first network equipment only stores a default route to the third network equipment, and the packet sent by the first network equipment is forwarded by the third network equipment according to the fact that the first network equipment is a spoke neighbor of the third network equipment, so that the resource consumption and storage pressure of the first network equipment are reduced.
