L2 Seven Port 10/100Mbit/s Ethernet
Switch Controller
Infineon XWAY™ TANTOS
®
XWAY™ TANTOS is the next generation of high performance, high integration
seven-port Ethernet Switch Controller especially designed for digital home ap-
plications such as ADSL/VDSL router, wireless router, EPON/GPON router, IAD,
IP set-top-box, HomePNA/HomePlug, VoIP and video applications.
The XWAY™ TANTOS provides most advanced Ethernet Swich Controller func-
tions including priority features by Port-Base, VLAN, UDP/ TCP destination port
number, ranged UDP/TCP port and IP TOS field checking. With its 802.1p (QoS),
Layer4 QoS, 802.1q (VLAN), security, bandwidth control/ guarantee, port mirror,
IGMP and management functions, the XWAY™ TANTOS meets perfectly custo-
mer requirements on multimedia applications. Each output port comprises
of four queues in the way of programmable rate fairness queuing, strictly and
assign bandwidth to fit the bandwidth demand on various packet types such as
voice, video and data. In addition, F 802.1Q, Tag/ Untag and up to 16 groups of
VLAN are also part of the XWAY™ TANTOS feature set.
To build internet access and to prevent un-authorize or multiple users sharing
one port traffic, the XWAY™ TANTOS performs security and port locking functions.
