| 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. | Token bucket is a simple and elegant algorithm for traffic shaping and rate limiting. A virtual bucket accumulates tokens at a fixed rate (the committed information rate). Incoming packets consume tokens (one token per byte); packets are transmitted only if sufficient tokens are available. If the bucket is full, excess tokens are discarded (no carry-over). Token bucket bounds peak rate and allows controlled bursts, making it ideal for traffic management in networks. |
