| Abstract |
Mobile networks typically go through a transformation every 10 years, with the new generation always bringing additional capacity and enhanced capabilities. This is not different with 5G: it promises blazing speeds, low latency, and better support for deploying applications closer to the subscribers. But operators need to prepare their IP networks before they can deploy any new radio access technology. This session will describe the radio access network evolution from distributed to centralized architectures, the innovations introduced by 5G and how they impact the IP network requirements. |

| Abstract |
In the past, when we designed, built, and operated networks as a collection of devices (routers, switches, and firewalls) we defined our network architecture in terms of physical layers. The three-tiered Core, Aggregation/Distribution, and Access model is familiar to every network engineer. Server virtualization and new application frameworks have forced us to reconsider this model. Instead of a multi-tier hierarchical design, we have found folded-Clos (spine-leaf) networks much more efficient at moving large quantities of packets from anywhere to anywhere. In order to keep up with the speed of virtualized compute and storage, we’ve adopted virtualized networks that run as an overlay (with the physical Clos network becoming an underlay).
Visualizing the network in this way gives us a new 2-tier model. Instead of trying to conceptualize the physical network into an outdated hierarchy, we can now look at the entire logical network platform as a two tier system. The (spine-leaf) underlay is the Core layer switch and the overlay is the Access layer router. This is super helpful when we want to decide where network functions should live. The Core is still there to move packets, fast, and the Access is there to handle routing and policy as well as to provide additional features and functions. |

Lossless Data Center Networks: Opportunities for NANOG Engagement with IEEE 802 Nendica

| Abstract |
New standards in support of improved data center efficiencies are emerging. In the IEEE 802 Standards Committee, the IEEE 802 "Network Enhancements for the Next Decade" Industry Connections Activity (Nendica), which identifies industry requirements and trends, has published its first report, covering lossless networks for data centers. This report documents trends to reduce and eliminate congestion that leads to packet loss and unacceptable latency in the modern data center. As a result of that study, IEEE 802 has already begun standardization on one solution, based on congestion isolation as an improvement to priority flow control. Nendica continues to seek user partnerships to help steer future standardization in a productive direction. In November 2018, Nendica cooperated with IETF on the 802/IETF Data Center Workshop, identifying many areas of potential cooperation and complementary opportunities. This NANOG presentation reviews some of the technologies described in the IEEE 802 Nendica Report "The Lossless Network for Data Centers." It also proposes opportunities for cooperation with communities such as NANOG with an interest in networks and data centers. |

| Abstract |
Have you ever wished you could tailor IGP computation to fit your own traffic engineering needs? Such as by computing:
Paths considering a subset of the routers in your network? – a network plane or slice
Paths that minimize cumulative delay to a destination based on measured per-link delay?
Paths traversing only encrypted MACsec links? Both for primary and pre-computed backup paths
Paths traversing only high speed interfaces
All the above use cases are now possible. And furthermore, they are possible at scale and based on the source routing paradigm. Meet SR Flexible Algorithms !!!
SR Flexible Algorithms (FA) is the latest standards-based tool in the SR TE toolkit. FA allows operators to tailor IGP SPF computation according to their own needs. An operator can define and assign new SR segments (prefix SIDs) to realize forwarding beyond SPF based on link cost. As a result, FA provides a traffic engineered path from anywhere to anywhere automatically computed by the IGP.
This presentation provides a technical overview of this new technology and its benefits for network operators, including:
Flexibility –operator defines algo
Simplicity –single IGP process, and single loopback with multiple SIDs
Scalability –single SID (instead of a label stack) can now be used to enforce traffic on the Flex-algo specific path
Rich functionality –optimum sub-50msec TI-LFA backup paths respecting the same optimization objective and constraints as the primary path
Automation –FA inherits all the scale and automation benefits powered by intent-based networking with on-demand SR policy instantiation and automated traffic steering
More importantly, presentation dwells into key use cases that leverage this solution; including:
Multi-plane network designs
Intent-based network slicing
Low latency routing
Secured Intelligent Transport
Why is this session relevant to NANOG?
FA is a new concept with large set of use cases. Thus, we consider that this topic will be of interest for the NANOG audience. |

Building the 400G Internet - Trends, Technologies, and the Road to 800G+
|
| Date/Time |
3:00 PM to 3:30 PM
|
| Location |
Grand Ballroom |
| Presenters |
- Speaker
- Christian Martin, Arista Networks
|
| Abstract |
In this talk, Andy Bechtolsheim will share his vision for how the 400G and 800G transitions will manifest first in the DC and short haul interconnect build-outs, and then extend to 100-1000km and beyond, all based on next generation digital coherent optical technology. Advances in DSP and modulation technology make it possible to include 400G, and soon, 800G coherent optical transponders in standard OSPF and QSFP-DD packages that are capable of greater than 1000km transmission over commercially available fiber. This technology makes it possible to build the next phase of intermediate and long haul Internet backbones with low cost, interoperable, generally available optics that leverage the same technology as short reach optics used in datacenters, thus minimizing cost by leveraging economies of scale. |

2) why? because .. someone turned into a transit network and now my customers.. wait, I have customers??
3) how? With software! (and some data and time)
4) I said this in Vancouver, merry xmas! wait, I am late... Happy Spring Cleaning Time? (dates for execution update) |
