Method and system for realizing two-layer intercommunication between in-cloud network and out-cloud network

Abstract

The invention provides a method and system for realizing two-layer intercommunication between an in-cloud network and an out-cloud network, and the method comprises the steps: configuring a database on an out-cloud switch, and enabling the information of an in-cloud virtual machine to be intercommunicated with the information of the out-cloud switch; registering a logic network in the database, configuring a binding relationship between the switch and the logic network, and determining a mapping relationship between an out-of-cloud network and an in-cloud network; based on the virtual machine information, generating an out-of-cloud access flow table on the switch, and based on the mapping relationship, performing flow table control of accessing the in-cloud network by the out-of-cloud network; creating an interaction port on the intra-cloud network, and configuring a one-to-one correspondence relationship between the interaction port and the switch and between the interaction port and the logic network; and according to the interaction port, generating an in-cloud access flow table, and based on the one-to-one correspondence relationship, performing flow table control of accessing the in-cloud network to the out-of-cloud network. The method is implemented on the two layers of the network without a router, and the whole process is completed through software, so that the hardware dependence is avoided, and the competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and a system for realizing Layer 2 intercommunication between a network inside the cloud and a network outside the cloud. Background technique [0002] In recent years, the demand for cloud computing business has developed rapidly. Cloud computing has gradually evolved from a concept into a product integrated into our daily life. OpenStack is a relatively mature open source cloud computing management IaaS platform. The OpenStack platform covers various basic functional services such as computing, storage, and network. Because the design pattern of OpenStack has been widely recognized by the industry, relying on the large-scale application of OpenStack in various industries, OpenStack has become the industry standard, especially the network Related functions In the connection with SDN (Software Defined Network, software-defined network), all SDN manufacturers basi...
