ZX279131

             The ZX279131 chip features excellent xPON interoperability enabled by its support for GPON, EPON, XGPON, XEPON, NGPON2, XGSPON, and P2P1G/10G modes and its compliance with ITU-T G.984.3, G.987.3, G.989, IEEE 802.3, and G.988 standards. It can process packets of various protocols, and its 2-port PCIe card support allows for operations in the double-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).
