This talk will introduce ONF's Trellis, an open-source multi-purpose leaf-spine switching fabric for data-center networking, built using bare-metal (whitebox) switches with support for multiple merchant-silicon ASICs. We will discuss the use of Trellis in CORD, as well as it's use independent of CORD.

In this talk, Broadcom will cover the evolution of OF-DPA from its inception to the present day. We illustrate how OF-DPA makes it possible to map OpenFlow Logical Switches to configurable switching pipelines that are available in production quantities today.  We also discuss the role of TTPs and other features of OpenFlow (like open specifications and extensibility) that acted as the catalyst for this transformation in networking.  

This presentation will give on overview on the various switches offered by Edgecore Networks for Trellis. The presentation will cover current hardware offerings as well as the software components included to support Trellis.

According to the situation that current open source implementations of M-CORD are not complete, we decided to research a workable and open-source solution. We choose OpenAirInterface, which is an open source Rel 8/Rel-10 3GPP compliant reference implementation of BBU, UE, RRH and EPC that runs on general purpose computing platform (Intel/ARM), to act as an LTE service (EPC and eNB part). We want to execute OpenAirInterface under CORD platform, so we integrate OAI service into XOS. After that, users can access the web UI to create and run OpenAirInterface inside OpenStack. Finally, we can demo mobile devices access the internet via M-CORD OAI services. At the current time, we can let users initiate OAI services from XOS web UI, use mobile devices to connect to our remote radio unit which communicates to OAI EPC in M-CORD and browse the internet after mobile devices are authenticated. We have completed the OAI-as-a-Service in CORD 2.0, and now trying to migrate to CORD 4.0. We are going to transform and optimize the current R-CORD 4.0 into OAI M-CORD 4.0. Hope it can be a good practice of M-CORD use case.

In the era of 5G, CORD in the edge of metro network will aggregate a variety of different services which require the huge and on demond of bandwidth,different SLA guarentee,Differentiated services provisioning. The interconnection network between CORDs should support network slicing, bandwidth on demand, and AI based controll. Here we want to present a new architecture-Slicing Packet Network, which can provide the end-to-end phisical layer isolation and packet switch. It can provide DWDM based optical layer(L0), 64b/66b block based coross connect(L1) , Ethernet switching(L2)+Segment Routing(L3). It is Disaggregated Transport Network.With SDN controller such as ONOS, It can replace the triditional OTN/ROADM and the routers in metro network in the future. China Mobile and their partners have verified it in Lab.

CORD is a disruptive technology aiming to redesign Telco Central Offices, bringing new standards of efficiency and agility.Ground-breaking NFV solutions have been developed in OpenCORD, shaking up the Service Providers networking model, as more and more functions, traditionally done in specialized hardware, are virtualized in CORD.But what about the physical networking infrastructure – the switches? Are they only good to provide connectivity? Rich in capabilities, switches can offer more services for CORD. Comprehensive telemetry, sophisticated QoS, NFV offload are just a few examples of what XPliant flexible hardware can do, while processing the traffic @ Tb throughput.Cavium has ported its' XPliant Family of programmable switches to ONOS Controller, empowering CORD to tailor the physical underlay Fabric characteristics to each of the Mobile/Residential/Enterprise use-cases specifics.With Cavium-Xpliant Programmable switches, the Fabric behavior and scale does not have to be one-size-fit-all; application-definable Fabric is not a fantasy.I believe that the next step in CORD evolution should be capitalizing on the benefits of both the flexible physical network and the virtualized NFVs.The result, a truly Software-Defined Network, programmatically adjustable to deployments needs, will be a big step forward to deliver on CORD's vision of offering an economics-efficient and agile solution.

SD-Collectors are the basis for deep observability & real time analytics. This talk provides how SD-Collector models can enhance CORD platform to enable applications & networks required by 5G
