Flexibilis Ethernet Switch (FES) is engineered as a triple-speed Ethernet Layer 2 switch IP, capable of gigabit forwarding on each port. Its design ensures compatibility with IEEEv2's end-to-end transparent clock, enhancing clock information reliability across expansive networks. FES provides flexible connectivity options, supporting various Media Independent Interfaces and optional adapters for different interfaces, enabling seamless integration with host systems and external PHY devices. The switch's core is a multi-gigabit forwarding engine supporting up to twelve full-duplex gigabit Ethernet ports, employing Weighted Random Early Detection to prioritize critical data streams during congestion. Additional features like VLAN tagging, packet filtering, and PTP synchronization further solidify FES's credentials for robust, high-availability Ethernet communications.
