Techniques are described for implementing secure communications between edge devices providing cloud computing services in an edge environment. A computing cluster can include a plurality of cloud-computing edge devices. The computing cluster can implement a distributed control plane for performing operations related to managing cloud infrastructure resources within the computing cluster. The cloud-computing edge devices can be connected to an intra-node switch to form a substrate network. The data related to control plane operations may be transmitted over the substrate from one edge device to another, such that control plane operations can be performed at any suitable edge device in the cluster. The edge devices can use an encryption protocol to encrypt the data transmitted over the substrate network via the intra-node switch.

The invention provides a high-strength composite material used for special cables and a preparation method thereof. In the invention, high-performance engineering-use polyether ether ketone, polyethylene and polyimide are employed as basic polymer materials. Hyperbranched polyurethane is used for modifying molybdenum trioxide and magnesium oxide filling materials and an ethylene-vinyl acetate copolymer is used for modifying silicon nitride and zirconium oxide crystal whiskers, thereby improving binding force between inorganic filling materials and organic substrates. Meanwhile, the hyperbranched polymer penetrates the organic substrate network, thereby improving total strength. The composite material ensures high-temperature resistance, fire-proofing performance and the like and reduces defect generation rate between organic and inorganic interfaces. Compared with special cable materials with non-modified filling materials, the composite material improves strength by more than 33%, thereby effectively improving the durability and reliability of the special cables in use.

The invention provides a virtual network mapping method based on a principle of proximity. In the method, when a substrate network node is selected in node mapping, not only is available resource taken into account, but also whether the principle of proximity is satisfied is taken into account, namely whether link connection exists between the substrate network node and the substrate network node which is successful in mapping; and in addition, a mechanism that a node is lined up according to the remaining resource in the virtual network node mapping and a mechanism that a link is lined up according to the bandwidth before the virtual network link mapping are introduced into the method. The virtual network mapping method based on the principle of proximity provided by the invention is suitable for the networks which are already used or are going to use a network virtualization technology to perform network segregation, resource management scheduling or customized service providing, such as an experiment network, an operator network. The virtual network mapping method based on the principle of proximity has the characteristics of low complexity of link mapping, high utilization ratio of the substrate network resource, high success ratio of the virtual request mapping, and the like.
