This document discusses SURFnet7, a scalable network in the Netherlands that provides high bandwidth connectivity and services to research and education institutions. Key points include: 1) SURFnet7 has no capacity limitations, uses resources efficiently, and is highly available and accessible. 2) It has a redundant point of presence (PoP) architecture across 14 cities to ensure availability. 3) SURFnet7 supports various connection types at speeds of 1, 10 and 100 Gbps using different fiber types. 4) Its multi-service port capability allows institutions to utilize a single port for multiple network services and lightpaths in an efficient manner.

16. OnDemand Lightpaths
• Possible to all OnDemand lightpath ports within the
SURFnet7 network (and beyond soon).
• Institutions can activate OnDemand lightpaths to each
other using an MSP
• Also to Cloud providers via NetherLight.
• Offers the same bandwidth, latency, availability etc.
