Embodiment Construction

[0049] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0050] figure 1 It is a schematic diagram of an access system based on a cloud virtualization network, see figure 1 , the access system based on the cloud virtualization network includes: a client (or called a user), a source website, an SLB, a Cache (caching) server and an SFC. The client may correspond to the end user, and the source website may correspond to the server.

[0051] Wherein, the SLB not only undertakes the load balancing function, but also needs to import and export traffic for the Cache server. The SLB includes: a network ingress and a network egress, and the network ingress and the network egress are separated. The network entry is mainly responsible for receiving client HTTP requests, and the network exit is mainly responsible for s...

Abstract

The embodiment of the invention provides an access method, device and system for a cloud virtualized network. The access method includes the steps: acquiring a first port of a client after receiving afirst request of the client; when the of is not When the first requested file data exists, binding the IP address of the client and the first port to a locally created communication interface when alocal cache of the Cache server does not have the file data of the first request; building a link between an SLB and a source website through the locally created communication interface, and sending the first request to the source website through the link between the SLB and the source website. The access method, device and system of the embodiments of the present invention can solve the transparent proxy problem when using the SFC technology in a virtualized network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cloud virtualization network-based access method, device and system. Background technique [0002] In the traditional mode, servers, networks, and storage are connected based on physical devices. Therefore, network policies for servers and storage are deployed based on physical ports, and devices and their corresponding policies are static and fixed. In the virtualized infrastructure, servers, networks, storage, etc. all use virtualization technology, and services are completely defined on the virtual network. The separation of the virtual network and the physical network makes the data center network more flexible and scalable. There are also a lot of Middleware (middleware) in the data center, such as firewalls, load balancers, etc. These devices are processed based on client services, and business processing functions such as virtual firewalls / load balancers / gateways are c...
