| Tiivistelmä≠ | BGP is the de facto standard routing protocol for interconnecting autonomous systems (ASs) on the Internet. Since its introduction in 1989, BGP has scaled the Internet to millions of routers and trillions of destinations. BGP is path-vector-based, using a flexible policy system to control route propagation and selection. While BGP convergence can be slow and policies complex, it remains the only viable protocol for Internet-scale inter-domain routing. | Network Function Virtualization (NFV) is a paradigm that implements traditional network functions (firewalls, load balancers, gateways, packet inspection) as software running on commodity servers instead of proprietary hardware appliances. Introduced by ETSI (2012), NFV reduces capital and operational expenses by leveraging cloud infrastructure and enabling rapid deployment of network services. Combined with SDN, NFV enables on-demand service creation and network slicing. It is now central to 5G and cloud-native network architecture. |
