Yes. &nbsp;Just like with Frame-Relay, some providers have Network-to-Network Interfaces (NNI) where they connect to other providers. &nbsp;If the providers in questions have NNI's to each other then it's rather easy to request an interconnection between services.

The new facility we are acquiring is located in London, UK. Do you think the NNI is possible between an overseas ISP (UK) and a US ISP?

We currently use MPLS connecting three facilities among three states in the US. The MPLS we use is provided by the same ISP. My company is in a mode of acquisition so in the future we may acquire a new facility where our current ISP don't/can't provide the MPLS whatsoever. So my question is, is it possible to use MPLS via different ISPs ?

Does MPLS need to be from the same provider?

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
