Generally disclosed herein is an approach for modifying use of segment routing multiprotocol label switching (SR-MPLS) allowing an arbitrary MPLS control plane and traditional MPLS data plane to utilize a single MPLS label to represent two or more edges in a path.

In one example, a single MPLS label may be divided into two sub-labels, the first sub-label representing a first edge, and the second sub-label representing a second edge. In this regard, longer source routes may be supported in a packet header in network designs that implement strict source routing.

A computer-implemented method, system and computer program product for applying hypervisor-based containers to a cluster of a container orchestration system. A container runtime of a worker node in the cluster of the container orchestration system issues a request to create a sandbox environment to store a pod containing one or more containers. Upon creating the sandbox environment for each pod to improve isolation, a network tunnel is created between the worker node and the sandbox environment without packet encapsulation in which the sandbox environment shares the same Internet Protocol (IP) address as the other end of the network tunnel in the worker node. Packets may then be routed (forwarded) from the worker node to the sandbox environment via the network tunnel using source routing. By utilizing such source routing, packet looping is prevented. In this manner, hypervisor-based containers may be applied to a cluster of a container orchestration system.
