bandwidthoptimering

Bandwidth optimization, often written in Danish as bandwidthoptimering, is the practice of increasing the efficiency of data transfer over a network by reducing wasted bandwidth and improving usable throughput. The aim is to maximize data delivery with the least resources, enhancing user experience and lowering operational costs. Bandwidth optimization is relevant for enterprise networks, data centers, cloud services, mobile networks, and internet service providers, where traffic patterns are complex and peak demand can overwhelm capacity.

Techniques commonly employed include traffic shaping and rate limiting to prioritize essential traffic and smooth bursts; data compression to reduce payload size; caching and deduplication to avoid sending duplicate data; protocol optimization to minimize overhead; and the use of content delivery networks (CDNs) and WAN optimization appliances to bring content closer to users. TCP tuning, such as adjusting congestion control parameters and window sizing, is also used to improve effective throughput in some environments. Architectures often combine several methods, adjusted to the specific network topology and service requirements.

Key performance indicators include utilization, goodput (effective data transfer rate), latency, jitter, packet loss, and retransmission rates. Trade-offs exist: aggressive optimization can add processing delay, complicate management, or reduce visibility into encrypted traffic. Security and privacy concerns arise when deep inspection is used, and end-to-end encryption can limit some optimization techniques. Successful bandwidth optimization requires careful measurement, ongoing tuning, and alignment with business goals and compliance requirements.

Applications range from corporate WAN and data center interconnects to ISP backbone optimization and mobile network traffic management.
