Multus CNI 3.9.3

• Allows for the use of multiple network interfaces on a pod, including multiple network plugins.
• Enables multi-homed pod scenarios, where a pod can have multiple IP addresses and network routes.
• Provides a flexible and extensible way to implement advanced networking capabilities, such as network function virtualization (NFV) use cases.
• Integrates with Kubernetes' existing CNI architecture, allowing for easy deployment and management.
• Supports a wide range of network plugins, including CNI plugins for popular cloud providers such as AWS and GCP.
• Provides advanced network policy support, enabling fine-grained control over traffic flows between pods.

• Multi-homed pods: Multus CNI is commonly used to enable multi-homed pod scenarios, where a pod can have multiple IP addresses and network routes. This allows for more advanced networking topologies, such as pods with one interface on a public network and another interface on a private network.
• Network function virtualization (NFV): Multus CNI can be used to implement NFV use cases, where pods can be assigned to different network functions (e.g., load balancers, firewalls) depending on the traffic they receive.

To use Multus CNI, you need to deploy it on your Kubernetes cluster and configure it to use the network plugins you require. Once deployed, you can specify multiple network interfaces for a pod using Kubernetes' annotations, and Multus CNI will handle the routing and configuration of these interfaces.

• Multus CNI is implemented as a Kubernetes CNI plugin and is deployed as a daemonset on each node in the cluster.
• Multus CNI uses Kubernetes' existing CNI architecture, allowing for easy integration with other CNI plugins and tools.
• Multus CNI supports a wide range of network plugins, including popular CNI plugins for cloud providers such as AWS and GCP.
• Multus CNI provides advanced network policy support, enabling fine-grained control over traffic flows between pods.
• Multus CNI is open source software and is available under the Apache 2.0 license.
