Hi,
I am in embedded R&D, and am looking for a Fast Ethernet switch with
really good trunking (link aggregation, LAG, etc.) support. If I have
a trunk group with 3 ports, than this is what I am looking for:
1) Auto-failover to other ports in the trunk group if one port fails.
2) A trunking algorithm that can handle if one port of the trunk group
maxes out its bandwidth and should not be assigned new connections.
Let the other ports catch up a little bit and don't throw away any
data.
3) Support for interfacing to Cisco's EtherChannel trunking.
4) Something else besides a MAC based trunking algorithm, to be able
to more randomly distribute 2-way connections between ports in the
trunk groups.
I have used a Broadcom part in a previous design that handles number
1, but not the others. Now I am looking at Zarlink devices (ZL504xx
family), but they don't handle 1 internally (I have to reconfigure the
trunk group after I get an interrupt, but I'll lose data).
This is for a VoIP application.
ANy suggestions appreciated!
