Shim DIF for HV
TERENA Networking Conferece, June , Porto

20. RINA shows potential in simplifying things
No need to implement complex and expensive NIC emulation.
No need to generate and assign MAC addresses,
No need to create and configure software L2 bridges to connect VMs and hypervisor physical NICs together.
Users of the shim DIF are not restricted to the Ethernet MTU (1500/9000 bytes)
Commonly bypassed using the TCP Segmentation Offloading (TSO).
No need to perform TCP/UDP checksumming since shared memory communication is protected from corruption
Checksumming is not actually performed by modern paravirtualized NICs (e.g. virtio-net, xen-netfront)

IRINA
Investigated how RINA relates to NREN services
Experimental setup of VM networking for distributed applications
Despite being a prototype, some aspects of the current stack already show performances close to state-of-the-art production software.
IRINA also developed part of the tools necessary to perform current and future experiments, pubicly available through the Geant Software License.
