TNSR Release 20.02 Now Available
Summary
Here are the highlights: The TNSR Mapping of Address and Port using Translation (MAP-T) Border Router (BR) implementation improves compliance with RFC 7599, and provides the following features: The addition of Shallow Virtual Assembly (SVA) to TNSR provides a more efficient method of processing fragmented IPv4 traffic by retaining Layer 3 and Layer 4 information so that any following fragments can have operations applied using the Layer 3 and 4 data from the initial fragment. When compared to full reassembly, SVA decrease buffers required for a given network load, while also decreasing latency across a network path. Additional details on how SVA works and how to implement it in TNSR can be found here. Interested in seeing how TNSR can transform your routing, firewall, or VPN needs?
