ZX279127S

       The ZX279127S chip features excellent xPON interoperability enabled by its support for GPON, EPON, and P2P modes and its compliance with ITU-T G.984 standard and the technical requirements of IEEE 802.3-2005 and CTC standards for EPON equipment. It can process packets of various protocols, and its 1-port PCIe card support allows for operations in the single-frequency Wi-Fi scenario. The chip has a built-in 4-port GE PHY interface module and an RGMII interface that connects with external PHY interfaces. It can serve a wide range of functions, including:

　　- L2/L3 multicast forwarding, L2 bridging, L3 routing, and NAPT;

　　- IPv4 and IPv6 dual stacks, DS-Lite, and 6RD;

　　- Flexible traffic classification;

　　- HQoS (Hierarchical Quality of Service).
