Delnettene

Delnettene is a term used in computer networking to describe a network architecture in which a larger network is partitioned into smaller, interconnected subnets. Each subnet maintains its own addressing and local routing policy, while gateways or boundary routers connect it to other subnets, forming a scalable and modular network fabric. The term is used in Norwegian technical literature and industry discussions about distributed networks and large-scale deployments.

Characteristics of delnettene include support for hierarchical or mesh interconnections, with inter-subnet routing handled by designated edge devices or routers that may enforce access control and quality-of-service policies at the subnet boundary. Local management allows autonomous operation, while a global policy aligns across the entire delnett. The approach can be complemented by software-defined networking to simplify control and programmability, improving adaptability to changing network needs.

Applications and benefits span enterprise networks, telecom carrier networks, data centers, and Internet of Things deployments, where modularity and fault isolation enhance scalability and resilience. Benefits include easier maintenance, localized policy enforcement, and the ability to grow the network incrementally without creating routing bottlenecks at a single point.

Challenges and considerations involve coordinating policies across subnets, address space planning, interoperability between vendors, and ensuring the reliability of boundary devices. Effective design requires clear boundary definitions, standard interfaces, and robust monitoring. See also: subnet, network segmentation, SDN, hierarchical routing.
