有很多种方法可以实现VPN。目前大家经常看到的有MPLS、IPSEC、L2tp/pp2p、SSL等类型。 MPLS的工作原理及MPLS VPN技术的特点 MPLS VPN是 ...

In certain models of inter-provider Multi-Protocol Label Switching (MPLS) based Virtual Private Networks (VPNs) spoofing attack against VPN sites is a key concern. For example, MPLS-based VPN ...

摘要：虚拟专用网(VPN)业务是最具潜力的新一代电信业务之一。基于多协议标记交换(MPLS)网络实现VPN的技术方案大大改善了 ...

DENVER — As extensions to the multiprotocol label switching standard make MPLS viable for virtual private network transport, experts are warning against taking the protocol too far, too fast. MPLS is ...

I’ve been asked often whether Multi-protocol Label Switching VPNs are secure. The answer depends on how you define security. I’ve been asked often whether Multi-protocol Label Switching VPNs are ...

正如我在之前文章中所讨论的，ADSL IP VPN具有诸多好处。服务供应商看到了这些即将来临的威胁，他们决定采取措施，为那些已经长期为MPLS IP VPN线路付出相对高昂费用的企业提供新的基于ADSL连接的MPLS IP VPN。就我们所知，新的基于ADSL连接的MPLS IP VPN基本上就是 ...

MPLS(多协议标签交换) VPN(虚拟专用网络)分几种?3层MPLS VPN和2层MPLS VPN?我不知道VPLS(虚拟专用网络服务)是否属于2层MPLS VPN，或者它其实就是2层MPLS VPN，只不过是另一种叫法。对于2层MPLS VPN，我知道BGP和LDP协议，而且还有其他MPLS VPN协议：虚电线(Pseudowire)和ADSL，可否 ...

One of the most compelling drivers for MPLS in service provider networks is its support for Virtual Private Networks (VPNs), in which the provider’s customers can connect geographically diverse sites ...

MPLS VPN is one of the most efficient VPN infrastructures that allows the usage of multiple protocol switching techniques to provide its services. It primarily consists of a number of sites that are ...
