New RFC about networks (July 2012)

Posted by on October 2, 2012

A few of the new RFC about networking that interesting personal to me. Just couple of words.

6660 – Encoding Three Pre-Congestion Notification (PCN) States in the IP Header Using a Single Diffserv Codepoint (DSCP).
Revision of RFC 5696. Revision of RFC 5696. It is further improvement QoS in the path to the ideal situation – when all devices will know how many throughput left anywhere and no one packet will be dropped. So,target this RFC is that new sessions will not be created if some congestion may appears.

6666 – A Discard Prefix for IPv6.
The very symbolic number for RFC where network 0100::/64 is defined as network for creation of remote triggered black hole (RTBH) in the IPv6. There were not DDOS attacks based of IPv6, but people will be prepared. That`s so nice. It is just recommendation, not a standard.

6669 – An Overview of the Operations, Administration, and Maintenance (OAM) Toolset for MPLS-Based Transport Networks.
This further work on the details of MPLS-TP, new perspective and popular protocol. In the workgroup you can see architects and engineers from all leaders of market – from Cisco to Deutsche Telekom.

6674 – Gateway-Initiated Dual-Stack Lite Deployment
As I wrote before, IPv6 is coming… coming… coming… )) but not so fast as everybody thought and dreamed. But IPv4 is over completely. And old good all-powerful NAT returned in the many new faces to help us. In this standard you can see many from NAT and for NAT, but not so many for IPv6, regardless of name. I think, I will read this standart again with attention.. somewhen.
