ühisvõrgus

Ühisvõrk is the Estonian term for a shared network, a communications infrastructure that is accessible to multiple users or organizations and enables the sharing of resources such as bandwidth, storage, services, and applications under common policies. In IT contexts it describes environments where participants can discover and use resources within a governed framework, rather than isolated, private networks. A shared network can be local, such as a campus or enterprise network, or wider, including municipal or cloud-based services, and it may also describe peer-to-peer configurations where participants contribute resources.

Typical characteristics and components include the use of standard networking technologies such as Ethernet and IP, plus services like DNS, DHCP, and VPNs. Access control is a key element, implemented through authentication, authorization and accounting (AAA), role-based access control, network segmentation (for example VLANs), firewalls, and encryption. Management is usually centralized by a network administrator or a governing body, with policies governing usage, security, privacy, performance, and monitoring. Interoperability relies on adherence to standard protocols and compatible services.

Advantages of a shared network include more efficient use of costly resources, reduced capital and operating costs, easier collaboration, and scalable service delivery. Challenges encompass security and privacy risks, potential performance contention, policy enforcement, and administrative complexity. Ühisvõrk concepts are central to campus and enterprise networks, municipal broadband initiatives, and cloud-based multi-tenant environments, where multiple users or organizations rely on a common infrastructure.
