A typical CSP network includes network equipment spanning multiple technologies such as SDH, DWDM, MPLS, and a wide range of access and aggregation equipment. A unique feature of the CygNet suite of solutions is the ability to automatically stitch and correlate interdomain information, in such a multi-vendor, multi-technology, cross domain environment across Layer1 / Layer 2 /Layer 3. This provides users with end-to-end visibility of services across domains at an individual circuit level, as well as at an aggregated level via the GUI and reports. This feature is a key enabler for rapid and accurate Service Provisioning and Activation, and minimizes fall-through of Service orders since CSPs are in possession of data that is critical to the creation of services in an optimal manner. The System provides mechanism to access CygNet inter domain system for all inter domain users.
