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).

Some technologies are chosen for consideration like SDH(Huawei), PVRST+(Cisco), RSTP(Zyxel), EAPS (extreme network) and MPLS(VPLS). The purpose is to provide L2 Ethernet connectivities from POPs to central point (DC) and ring protection.
