The UK Network Operators' Forum is currently only running online meetings.

UKNOF46 took place on Tuesday, 19 January followed by a BYO Pints n' Packets social event.

UKNOF events offer an OPEN environment for anyone within or interested in the Internet Industry. Network with industry colleagues, participate in knowledge sharing and freshen up on best practice around network operations and security.

For more information about UKNOF itself, please visit our primary site.

        The future of 100G, 400G, 400+G & 800Gig optics. - It's Confused! 30m

        With the advent of 100G, a wide range of different transmission standards and form factors were published by IEEE and MSA groups. This produced a plethora of transceivers and created a difficult choice for the best solution for networks and datacentres, for todays and also future needs.

        For 400G and 800G, IEEE and multiple MSA groups have published more than 30 transmission standards, with even more planned to be published in the near future. To make thing even more complex the different groups use different approaches for their standards and new technologies for transmission.

        This presentation will shine a light on the fuzzy variety of 100G, 400G, 400+G & 800Gig transmission standards, to show the activities of different MSA groups, to give an overview of existing and upcoming standards and to show which technologies will probably become most important in the future.

        XR Optics. Next generation access using all-optical subcarrier multiplexing 30m

        One of the biggest costs in any access network is the need to adapt lower access data rates into higher data rate backbone transport. Historically this has been achieved using either OTN switching in legacy systems or packet switching for modern applications. All-optical communication would obviously remove the need for expensive Optical-Electronic-Optical interconnects, but until now it has not been possible to achieve data rate adaptation in the optical domain.
        This presentation introduces a new industry initiative to create an all-optical aggregation and multiplexing capability based on Nyquist subcarriers. The initiative is called XR Optics, and is an open consortium of optical component companies, coherent DSP developers and system vendors. The presentation will focus on a technical explanation of the new transponder design, the need for standardised form factors, implications for host support, and the implications for the optical access network.

        pygnmi : Developing Python module for gNMI 30m

        There has been no good Python library to manage the network elements using the gNMI. To overcome this limitation, we’ve decided to create our own. Being non-professional software developers, it is also an interesting learning curve.

        As such, the talk will share the status of the pygnmi library development, examples of usage and integration with existing automation frameworks and story of the development.

        RFC3849 and RFC5737 20m

        Documentation is an important part of the life of a network engineer, whether we like it or not.
        Unfortunately, not all documentation is created equal, and there's well documented cases out there where bad documentation does more harm than no documentation.
        In this short talk, I'll talk about the deployment of, and how that relates to documentation.

        IPv6 at 25 20m

        IPv6 turned 25 in December. While global adoption of IPv6 might not be where its architects thought, IPv6 has come of age and inserted itself firmly into the Internet. This talk takes a look at how far has come.

        RIFT - Engineering Simplicity in IP Fabric 20m

        In this presentation we will take a look at a new and novel routing protocol for the datacenter underlay; Routing in Fat Trees. Or in short, RIFT.
        RIFT solves some of the challenges current datacenter underlays are facing; large IGP domains, zero touch provisioning, 5 or even 7 stage specific fabrics challenges, slow BGP convergence, etc.

        IP Flexalgo 20m

        An IP Flexible Algorithm allows an IGP to compute constraint-based paths. Therefore, it allows an IP network to achieve some TE capabilities without deploying MPLS or Segment Routing.
