Demo the SRCnet global networking architecture

The SRCnet needs to understand the existing network infrastructure, and how it will evolve with the adoption of new standards (e.g. IPv6). This will help the NREN-SKA Technical working group to determine the future requirements of the global network, and where investment is needed.

Internet Protocol version 6 (IPv6 ) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. 

 In IP-based computer networks, virtual routing and forwarding (VRF) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. One or more logical or physical interfaces may have a VRF and these VRFs do not share routes. Therefore, the packets are only forwarded between interfaces on the same VRF.

 In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard.^[1] The payload limit for jumbo frames is variable: while 9000 bytes is the most commonly used limit, smaller and larger limits exist
