Packet Forwarding Ability
The ES8108/ES8108F features a packet filtering function for broadcast packet control
protection and Quality of Service (QoS). Both features can provide higher performance in a
crowded network through traffic filtering and prioritization
Broadcast Control
The ES8108/ES8108F begins to drop broadcast packets with DA (destination address) equal
to FF:FF:FF:FF:FF:FF if the received broadcast packets are more than the threshold, 198
packets/per second at 100Mbps or 19 packets/per second at 10Mbps link speed.
All ports are enabled with this function by default to provide better network performance and
prevent congestion caused by the flooding of broadcast packets.
Quality of Service
The ES8108/ES8108F supports the frame type priority function, where high priority packets will
be queued to a high priority queue to share more bandwidth. The ratio of bandwidth of the high
priority to the low priority queue is 8:1. After 8 high priority packets are processed, then 1 low
priority packet is processed. Both the ES8108 and ES8108F can examine the specific bits of
VLAN Tag and TCP/IP TOS of IPv4 and IPv6.
