GENERAL DESCRIPTION
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). The RTL8309N supports several advanced QoS functions with four-level priority queues to improve multimedia or real-time networking applications, including:● Multi-priority assignment
● Differential queue weight with WRR and SP packet scheduling
● Port-based and queue-based rate limitation Energy-Efficient Ethernet (EEE) supports Low Power Idle Mode. When Low Power Idle Mode is enabled, systems on both sides of the link can disable portions of the functionality and save power during periods of low link utilization.
