Thus Carrier Ethernet technology also should be able to provide the same service as IP/MPLS. 1. Slow Network Recovery: STP 2. VPN ID (=VLAN ID 4K) Limitation 3. MAC Learning Issue 4.

The existing IP routing networks or MPLS networks have already these restoration functions. Hence, when multiple failures occur, the networks are restored and do not have to suffer service interruption only if there is at least one path available. However, in PBT networks, restoration functions are based on 1:1 protection. So, if multiple failures occur, the network cannot be restored properly, which apparently can be a serious issue. For this, KT has designed its network double-failure tolerant (KT: annual average of 50 fiber cuts including planned ones). • IP, MPLS network: provide restoration functions. • PBT, SONET: does not provide restoration functions
