Innovation Projects DPUDirect DPU SIG DPUDirect creates a collaborative operating environment for services, enabling them to be easily offloaded and ported between hosts and DPUs. The feature includes of service code on the management plane is needed to ensure software compatibility and evolving services, as well as reducing component maintenance costs. Features The figure illustrates the architecture requirements of the management-plane processes, eliminating the need to split and reconstruct too many services. PCIe communication channel/network Cross-host insensible collaboration framework – qtfs Common

is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation built on top of Cilium and BPF to enable deep visibility into the communication and behavior of services as well as the networking infrastructure in a completely transparent manner. By building on top BPF powers. Hubble can answer questions such as: Service dependencies & communication map What services are communicating with each other? How frequently? What does the service dependency graph look like
