Network Services: Ethernet

CIR is Committed Information Rate. This is the data rate which is guaranteed under the Service Level Agreement i.e., has defined performance criteria. In the case of Tata's dedicated Ethernet product, Tata will reserve this amount of bandwidth on the fibre network for this specific customer. For MPLS-based products, the CIR is shared bandwidth but is capacity managed, with more fibre capacity added to avoid congestion in normal operational conditions.
