Abstract: Some embodiments provide a novel method for defining policies for a container cluster that is configured by a first software defined network (SDN) controller cluster. A second SDN controller cluster for defining service policies that are not defined by the first SDN controller cluster receives, from a set of one or more adapters deployed in the container cluster for the second SDN controller cluster, resource identifiers for several resources of the container cluster. The second SDN controller cluster uses the resource identifiers to define a set of service policies. Then, the second SDN controller cluster distributes the set of service policies to a set of network elements to enforce the set of service policies on data messages associated with machines deployed in the container cluster configured by the first SDN controller cluster.

Abstract: Example methods and systems for flow-based secure packet forwarding are described. In one example, a first computer system may assess validity of a security token associated with a flow of one or more packets. In response to determination that the security token is valid, a security association associated with the flow and the security token may be negotiated with a second computer system. The first computer system may process a packet associated with the flow and the security token to generate an encapsulated encrypted packet by performing encryption and encapsulation based on the security association. The encapsulated encrypted packet may be forwarded towards the second computer system to cause the second computer system to perform decapsulation and decryption, and to forward a decapsulated and decrypted packet towards the destination.

Abstract: Described herein are systems, methods, and software to manage the deployment and use of application identifier tokens in a distributed firewall environment. In one implementation, a computing environment generates tokens associated with application types executing on virtual nodes in the computing environment. After generating the tokens, the computing environment provides at least one token of the tokens to each of the virtual nodes based on at least one application type executing on the virtual node. When a communication is identified in the virtual node associated with an application, the virtual node may encapsulate the communication and a corresponding token in a packet and forward the packet via a virtual network interface associated with the virtual node.
