虚拟专用网 (VPN):
VPN 是针对虚拟专用网络的,是一种属于专用网络但虚拟的网络类型。通过应用 VPN,我们可以将公共网络用作专用网络,因为 VPN 是处理加密、完整性保护和认证或身份验证的工具。它通过公共网络模拟专用网络。这允许用户远程访问专用网络。与 MPLS 不同,在 VPN 中,路由划分和流量由客户处理。在 VPN 中,需要所有 OSI 层才能使 VPN 发挥作用。

多协议标签交换 (MPLS):
MPLS 用于多协议标签交换,是一种至关重要的数据承载系统。它的功能与分组交换网络和电路交换交换网络非常相似,在分组交换网络中它模拟电路交换网络的一些特性。在 MPLS 中,标签交换方法用于为每个数据包分配一个编号或标签。每个数据包上的标签或编号在数据包转发过程中起着重要作用。 MPLS 在 OSI(开放系统互连)模型的第 2 层和第 3 层上运行。 MPLS 是一种更可靠的技术,因为它可以保证服务质量 (QoS)。

虚拟专用网(VPN)和多协议标签交换(MPLS)的区别:

S.NO MPLS VPN
1. MPLS supports multi-point technique. Whereas VPN also supports multi-point technique as well as point-to-point technique.
2. The cost of MPLS technology is higher as compared to VPN. While the cost of VPN is low comparatively.
3. MPLS does not operate encryption. While VPN exploits encryption.
4. MPLS operates on OSI layer 2 and layer 3. While here, all OSI layers are required to make a VPN functional.
5. MPLS is a high reliable technology comparatively because it assures the quality of service. Whereas VPN is also reliable technology for the delay sensitive traffic.
6. In MPLS, routing divisions and traffic are handled by the service provider. While in VPN, customers handle the routing divisions and traffic.
7. In MPLS, cloud-based services are limited available. While in VPN, cloud-based services are available wide range.
8. In MPLS, every blocked sites can be unblocked. While in VPN, not every blocked sites can be unblocked.
