My vote goes to proprietary ring protection from the vendor you choose: - EAPS (Extreme) - REP (Cisco) - MRP (Foundry/Brocade) - EPSR (Allied Telesis)
Although EAPS is implemented in all Extreme switches, select models from the other vendors implement ring protection, but these models also do other things you might want your network to have (QinQ, per-VLAN controls).
