Comparison and Analysis of mpls vpn and VLAN + ACL
Scope of application: VLAN is essentially a LAN technology and is suitable for LAN isolation. However, VLAN alone cannot guarantee the isolation of IP services and must be used with ACL. In this way, all business systems are in the same IP address space, which is visible to each other and not truly isolated, leaving hidden risks for network security. Mpls vpn
I. VPN concept
VPN is a secure and stable tunnel through a chaotic public Network. Through packets and encrypted transmission of network data, a temporary and secure connection is established in a public network (usually the Internet, in this way, private data can be transmitted on the public network to reach the security level of the private network. If the access method is dial-up, it is called VPDN. Gene

SSL VPN principle
If you separate the two concepts of SSL and VPN, you should know what they mean, but as a new technology, how they are combined may not be well understood. From the academic and commercial point of view, because they represent a different meaning, so often be misinterpreted.
SSL (Secure Sockets Layer) protocol is a common protocol that guarantees the security of sending information on th
As we all know, due to the shortage of public IP addresses, we usually use reserved IP addresses as internal IP addresses when establishing a LAN. These reserved IP addresses cannot be routed over the Internet, therefore, normally, we cannot directly access hosts in the LAN through the Internet. To achieve this goal, we need to use VPN tunneling technology.-Generally, the VPN gateway adopts a dual-network c

An important core task in VPN
VPN access network technology is still developing very rapidly. At the same time, it can be seen that the market demand is growing and users are also increasing. I believe that with the technological innovation, its development prospects will be even better, it will lead the rapid development of the communication industry. In recent years, Virtual Private Network VPN established on public networks has devel
1. Why does Cisco push the second-tier tunneling protocol, rather than the third-tier tunneling protocol?
Both options are available from Cisco. Cisco did not highlight that one. The second-tier tunneling protocol is primarily used to access VPN schemes, while the third-tier tunneling protocol provides VPN support for intranets and extranets. The third-tier tunneling protocol can also be used for some
