RTL8309N Descrizione generale
General DescriptionThe RTL8309N is an 8-port Fast Ethernet switch controller that integrates eight MACs, and eight physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.The RTL8309N contains a 2K-entry address lookup table. Two 4-way associative hash algorithms avoid hash collisions and maintain forwarding performance.Maximum packet length can be 2K bytes. Three types of independent storm filters are provided to filter packet storms, and an intelligent switch engine prevents Head-of-Line blocking problems.The RTL8309N supports 16 VLAN groups. These can be configured as port-based VLANs and/or 802.1Q tag-based VLANs. The RTL8309N also supports four Independent VLAN Learnings (IVLs).Service Quality Supports high performance QoS function oneach port: Supports 4-level priority queues Weighted round robin service Supports strict priority Input/Output port bandwidth control Queue based bandwidth control 1Q-based, Port-based, DSCP-based, IPaddress-based, and other types of priorityassignments Supports IEEE 802.1p Traffic Re-markingSecurity and Management Supports reserved control frame filtering Supports advanced storm filtering Optional EEPROM interface forconfigurationVLAN Functions Supports up to 16 VLAN groups Flexible 802.1Q port/tag-based VLAN Supports four IVLs Leaky VLAN forunicast/multicast/broadcast/ARP packetsPower Saving Functions Supports Energy-Efficient Ethernet (EEE)function (IEEE 802.3az) Link down Power Saving Mode
