De-bogonising 2a10::/12 | RIPE

With the RIPE NCC having become the first RIR to receive an additional /12 IPv6 allocation (2a10::/12) from IANA a few months ago, we will soon begin to delegate space from this IPv6 block to LIRs. In preparation for this, in order to improve routability and minimise the risk of filtering, the RIPE NCC will perform several de-bogonising activities in the next few weeks.We plan to start announcing the full /12, as well as a few /32 or longer blocks out of 2a10::/12 from AS12654 (RIPE Routing Information System (RIS)), within the next few days. We will analyse data from RIS and RIPE Atlas and we plan to write up an analysis around this effort.We want to remind everybody to update their bogon filters and allow routes originating from 2a10::/12 in their network.

A short history of TCP vs BBR – Video – Packet Pushers

A short history of TCP vs BBR [full version]

Watch this video on YouTube.

Geoff Huston, APNIC’s Chief Scientist, breaks down how TCP and BBR work to show the advantages and disadvantages of both.Highlighting that BBR wins because its stamps all over Cubic. Survival of the fittest means that legacy OS with old TCP flow control will be worse off and die quicker. Which is nice.

Vodafone tests open cellular radio tech that could lower call costs

Open standards for radio networks ? … ‘3 steps forward, and less than ⅛ back’ ?

Your wireless carrier is usually beholden to using proprietary cellular network tech from the likes of Ericsson or Nokia, but there may soon be a more universal technology that could benefit your bank account. Vodafone has started the first European tests (specifically, the UK) for OpenRAN, an Intel co-developed open access radio system that harmonizes hardware and software in cellular infrastructure. It doesn’t sound exciting, but it effectively opens the door to lower-cost cell networks — and that, in turn, could lower the costs of your calls and data.
