Aimed at the problems that the traditional VPN does not support the carrying of multiple data types,lack of security of data,and overweight label edge devices,an integrated VPN solution is proposed..The design includes the establishment of GRE VPN,the establishment of IPSEC VPN,the virtualization of network equipment,the establishment of MPLS VPN,the recogni-tion and isolation of private network data,to realize the nesting of each VPN technology data and the mutual integration of each VPN technology.The integrated VPN supports multiple data types,also supports the security of data interaction,and can achieve private network data access control and address reuse,and can also realize the load sharing of data.In order to verify the feasibili-ty of the scheme,tunnels,network resource pools,and label forwarding paths established by the scheme have been tested and ve-rified,and expected goal is achieved.In order to highlight the advantages of the scheme,it is compared with traditional methods in terms of backplane bandwidth and port rate.The analysis results show that the backplane bandwidth and port rate of the scheme increase with the increase of the device number in the resource pool,and its data transmission capability is multiplied compared with the traditional mode,and the data load is reduced.It is superior to the traditional scheme in load sharing,data security,ma-nageability and maintainability,and provides an new ideal for building a practical,reliable and secure VPN.
