Network Service Provider (NSP)
A business or an organization that sells internet and network connectivity by providing access to the internet backbone and infrastructure services.
Network Service Provider Details
A network service provider (NSP) provides internet backbone access to Internet Service Providers (ISP). These ISPs, in turn, sell internet services to businesses and consumers. Some NSP organizations also perform the role of ISPs, thereby creating a direct line of access with the end-users.
A NSP builds a network of fiber optic cables and core routers that act as the internet's main carriers. These physical cables come together at points called peering points. Regional ISPs can connect to the NSP backbone via these peering points. NSPs form the basis of high-speed Internet infrastructure and services. Their massive network supports a large downstream of ISPs, carriers, and network operators.

Significance of Network Service Provider
A NSP offers bandwidth features to ISPs which in turn is responsible for creating a last-mile connectivity infrastructure. Last-mile infrastructure refers to the final leg of a telecommunication network that delivers services to the end-users. NSP provides all the necessary infrastructure to ensure smooth network connectivity at the consumer end. NSP also ensures that they continually build, maintain and expand their network infrastructure to meet growing traffic demands.
A NSP also sells a host of other features to ISPs like web hosting and cloud services. These products, services, and features are white-labeled under the ISP's name and sold to the end customers. A white-labeled product is a product or service created by a company but marketed and sold by another company as their product.
Network Service Provider vs. Internet Service Provider
An Internet Service Provider is an organization that provides internet services to end customers and businesses. They act as the access point for a user to start consuming the internet. On the other hand, a network service provider sits at the top of the worldwide network hierarchy.
When a user connects to the internet using a modem, they establish an authentic connection with the ISP. The ISP then connects to the NSP's backbone, and the end-user starts receiving data from the internet. NSP is responsible for creating the entire infrastructure that makes up the internet.
