The uses of MPLS VPN and SDH dedicated lines and the differences between them

In the actual process of group networking or enterprise private network construction, technology and technology will be cross-used to achieve smooth operation of the network. What is the difference between it and a dedicated line?
It is based on the transmission network and is similar. : The bandwidth allocated to you will never be allocated to others even if you don't use it. Characteristics are: stability and security; this kind of application is generally within a city or a province.
, / is based on technology and is based on network technology. Because it is based on the network, it has a wide bandwidth and can be deployed nationwide. The price is relatively cheap. Although it is not physically isolated like that, it is logically isolated, so the security is unquestionable.
Under normal circumstances, if nationwide or global network deployment is implemented, it is generally recommended to use the Internet. If it is only network deployment within a city or province, you can consider a private network. The specific needs depend on the communication needs and budget of the enterprise.
It is widely used in multinational networking projects. Its networking cost is low, its networking flexibility is high, and its security is good.
Dedicated lines are mostly used in domestic cross-regional networking applications. The technology is the second layer of circuit security, which is better, but the networking is not very flexible and the price is high.
