Advanced Technologies & Protocols

• Dynamic Device Personalization (DDP): Programmable pipeline that enables the parsing and routing of specific protocols (e.g., GTP, PPPoE, VXLAN, NVGRE) directly on the controller chip, freeing up host CPU cycles.

• Application Device Queues (ADQ): Filters application traffic to dedicated queues, reducing latency and dramatically improving application throughput predictability.

• RDMA (Remote Direct Memory Access): Concurrent support for both iWARP and RoCE v2 (RDMA over Converged Ethernet) protocols. Ideal for ultra-low latency storage networking (NVMe-oF, Storage Spaces Direct).

• Single Root I/O Virtualization (SR-IOV): Supports up to 256 Virtual Functions (VFs) and up to 8 Physical Functions (PFs) for hyper-scale cloud deployments.

• Time Synchronization: Supports Precision Time Protocol (PTP) IEEE 1588 v1/v2 for accurate clock sync in telecom and financial tasks.

• Virtualization Offloads: VXLAN, NVGRE, GENEVE overlay network offloads.
