There are several ring technologies that are interesting but again it depends on what services you are planning to run and what kind of SLA guarantees you need: - RPR (802.17) : This has quieted down but it is a fairly robust technology giving you packet rings with 50ms, CoS, fairness and upto 255 nodes in a ring - EAPS: This technology is more vendor specific (eventhough an informational RFC exists) - ERPS (G.8032 - ITU) : This standard from ITU folks supports ethernet based packet rings and is comparable to EAPS - SONET/SDH : This is tried and tested but do you want to deploy a TDM based technology if most of your traffic is packet based - MPLS/VPLS : This is a layer 3 based and may not work for pure layer 2 service providers. It is tried and tested but does have some operational complexity built-in compared to layer 2 based technologies I agree with an earlier suggestion made, do not mix vendors if you want service level interoperability.

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.I know you all are in those network for years. can you give me some advises?Best regards, chanty
