is introduced, the ATM exchange uses the routing protocol to exchange layer-3 routing information with other devices. 　　 Label structure: 　　 　 The label field of 20 bits is used to indicate the label value. Because the label is fixed length, you can analyze the label of a vro to forward data packets. This is the biggest advantage of label exchange, the Fixed Length Label means that data forwarding can be implemented using hardware. This hardware forwarding method is much more efficient than

With the gradual popularization of the network, more and more enterprises begin to establish their own branches in multiple places. However, because many internal applications of enterprises involve business privacy, therefore, how to make the branch structure securely and smoothly use these applications becomes a topic of concern to every enterprise network administrator. Generally, we can use VPN security devices to implement remote user or branch a

NAT and ipsec vpn of link Balancing Devices (1) when implementing a new link Load Balancing Project, the user's previous egress devices are usually firewalls, if the organizational structure of a user is distributed, it is often necessary to build a security tunnel to communicate with the headquarters or branches over the internet through the ipsec vpn. In this case, the firewall is used as an egress device

How to Improve VPN security As we all know, VPN (Virtual Private Network) uses tunnels to transmit data between two networks on the wide area network. Because its data is transmitted on the Wide Area Network, although the tunnel technology can provide certain security protection. For example, when data is transmitted in a VPN tunnel, data packets are encrypted
