Kubernetes networking : is there a cheetah within your Calico?

February 6, 2022 4:30pm - 5:00pm CET

YouTube PDF

Even faster kubernetes clusters with Calico, VPP and memif Kubernetes is great, containers are lightweight & disposable, networking is simple yet powerful. But when it comes to network oriented applications, oh that can be slow ! That’s how the Calico/VPP integration first came up, as a way to address performance bottlenecks, making VPP’s performance the motor of Calico’s functionalities in Kubernetes. It speeds up container networking, but also allows us to expose even faster functionalities directly to the applications.

Keep appetite for the stats, it costs nothing

February 6, 2022 2:20pm - 2:40pm CET

YouTube PPT

Presentation of the statistics consumption model in VPP from the costless low-level design to their exploitation in userspace VPP (aka Vector Packet Processing) is a fast network stack running in Linux userspace. It is designed to handle packets with high performance, which makes gathering statistics efficiently a must have. The model that has been chosen in VPP to provide up to date statistics is built upon shared memory and optimistic locking.

Calico/VPP: Using Calico’s Pluggable Dataplanes for Fun and Fast Networking

October 15, 2021 11:55am - 12:30am PST

YouTube PDF PPT

The Calico VPP dataplane, introduced during last year’s KubeCon, adds a new networking option for Calico on Linux alongside iptables and eBPF. This takes advantage of Calico’s pluggable dataplane support, which offers futureproofing and agility for the user in dataplane choices. As it turns out, having VPP’s flexible and modular userspace networking stack in a Kubernetes environment enables all sorts of interesting things – such as allowing network-intensive pods to send and receive data at ludicrous speeds while conserving the CNI features we love, thanks to kernel bypass.

Low Trust Edge Network? No Problem - Get Great Performance and Security Using Calico, VPP, and WireGuard

October 12, 2021 11:20am - 11:50am PST

YouTube PDF PPT

As we’re learning from the other sessions at this summit, Kubernetes has many applications in the Enterprise Edge. However, Edge networks are more difficult to physically protect against malicious parties or other interference, so it becomes critical that security is implemented, not only between pods, but also to protect traffic on the wire. To add to the challenges, in an edge Kubernetes deployment, making the best possible use of the available CPU resources is even more critical than normal due to limited available resource - you can’t just buy a bigger instance, here!

Calico/VPP : Kubernetes networking with boosters

July 22, 2021 09:00am - 08:00am PST

YouTube PDF PPT

Kubernetes has become the de facto solution when it comes to container networking, providing rich functionalities and abstractions. But some classes of workloads put a huge performance burden on these implementations. Think big data, storage, analytics, 5G, virtual network functions, requiring encryption at a 40Gbps line rate, or multiple million of packets per second. Typically applications that are used to having dedicated NICs and physical hardware. In order to address this, we took the best of both worlds, combining Calico, the popular cloud native Kubernetes network plugin, with VPP, a very fast and scalable userspace packet processing software.
