I am in process of planning ring network to cover 15 POPs in City. 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.

Of the above, VPLS. But it really depends what you need to do. If you're selling customers cross-town L2 services then yeah VPLS is the best option in my opinion. If this is for use between your own equipment, other technologies might make more sense. I echo Roland's comment, but I'll make it more specific - stay away from anything with spanning tree in it. -- Nathan Ward
