LinuxCon + ContainerCon Japan 2016

In this presentation, Taichi Kawano will introduce use cases of the data center network by using the white box switch, Linux-based network OS, and open source, and discuss potentials and challenges of the open source for the network carrier.

2015 saw the arrival of multiple 100Gbps networking technologies: Fast 100G Ethernet switches, Mellanox released EDR (100G Infiniband) and Intel came up with OmniPath (also 100G). 2016 is therefore likely going to be a battleground of these competing technologies. Facebook already is supposed to upgrade their infrastructure to 100G in 2015 and its likely that others are going to follow. This talk gives an overview about the competing technologies in terms of technological differences and capabilities and then discusses the challenges of using various kernel interfaces to communicate at these high speeds (POSIX, RDMA, OFI).
Hopefully we can come up with some ideas how to improve the situation.

Container-based NFV is becoming more and more popular in academia and industry because of the short provisioning time, low overhead, good scalability and reusability. But container networking based on kernel space interfaces and stack remains limited in performance and scalability.

This paper describes virtio for container technology, providing a scalable, high-performance, user space virtual network interface for L2/L3 VNFs and a customizable stack for L4+ VNFs. This allows NFV container instances to be easily integrated with OVS-DPDK and FD.io (or other vSwitch technology). This approach has been prototyped with DPDK. Initial performance testing shows a significant performance gain for both L2/L3 and L4+ VNFs comparing with existing kernel-based networking technologies. Besides, we also present next steps to gather industry feedback to help guide the future direction of this project.

In a world of ubiquitous Continuous Integration testing, Continuous Delivery is becoming a requirement for modern open source SDN/NFV projects. Integration-focused projects like OPNFV can only validate consumed upstream projects as frequently as they provide testable release artifacts. As integration tests become more frequent (towards Continuous Integration), the frequency of the integrated projects’ releases must increase (towards Continuous Delivery).
The release artifacts expected from modern open source projects are also becoming increasingly complex. Vagrant boxes and Docker containers need to be built alongside traditional packages. Configuration management options like Ansible and Puppet need to be provided.
Learn about changing CD requirements and modern CD pipelines. The delivery pipelines OpenDaylight built in response to OPNFV’s new CD requirements will be used as examples.

Fujitsu applies OpenStack for providing hybrid cloud service.
In this presentation, Miyashita will introduce learning from real practice of providing highly
available hybrid cloud service with OpenStack Neutron.
He will talk issues and solutions which Fujitsu faced through providing
hybrid(public/private) cloud service.
- How to build multiple OpenStack-based datacenters for public cloud with high availability
- How to build hybrid cloud environment(Connecting public cloud and on-premise datacenters)
- High available functionality spanning multiple datacenters(ex.loadbalancing service, security group)
