Network Integrity 7.4.0 now supports the discovery of the following physical and logical entities, and manage them (create, add, modify, and delete):

• STM Link Connectivities
• Trails
• Tunnels
• Topological Links
• Services, such as MOT, VPLS
• OTS – Topology
• OMS
• Och
• OTU/Cn
• ODU/Cn
• ODUFlex
• IDU resources
• Client service
• DWDM network entities: Physical device, Chassis, Shelf, Card, Port, Interface/sub-interface
• IMS Domain network entities: NE, Frame, Module, Shelf, Port, Interface

NI uses multi-threading to reduce scan duration and use resources more efficiently. This allows for the discovery of both logical and physical entities from the network while also importing data from the inventory.

Network Integrity 7.4.0 allows you to initiate groom and rehome operations to move services between devices and interfaces in SDH and DWDM networks in Unified Inventory Management (UIM). Once the groom and rehome operations are completed, NI updates the discrepancies in end points of physical and logical connectivity found between discovery and imported scan data.

See FTP SDH Logical Resource Discovery and Assimilation Cartridge Guide and CORBA Based DWDM Layers and Service Discovery and Assimilation Cartridge Guide for more information.

NI 7.4.0 now supports a Network Management System (NMS) Listener for SDH and DWDM networks that captures all notifications from physical and logical devices and saves them to the database. You can start or stop the NMS Listener or check its status.

See Optical TMF814 CORBA Cartridge Guide for more information.

You can now use Security Assertion Markup Language 2.0 (SAML 2.0) protocol to implement Single Sign-On (SSO) and Single Log-Out (SLO) in NI. You must use an Identity Provider (IDP) to configure SAML 2.0.

See Configuring Network Integrity to Enable Authentication using SSO/SLO and IDP using SAML in Network Integrity Installation Guide for more information.

The TMF814 discovery cartridge now discovers nodes using NMS notifications from devices, instead of performing a full discovery scan.

See Network Integrity Optical TMF814 CORBA Cartridge Guide for more information.

NI 7.4.0 supports discovery of devices from multiple network domains. The Generic SNMP Cartridge can be used to discover and model logical and physical devices in IP networks. You can also perform import scans and reconcile data in UIM using this cartridge.

See Network Integrity SNMP Discovery and UIM Integration Cartridge Guide for more information.

You can now apply a filter on the device and equipment specifications to choose the type of device to be discovered or imported. You can set the filters based on the vendor and device types and NI will discover or import the devices from the network, as well as device notifications, according to the filters applied.

See Network Integrity UIM Integration Cartridge Guide for more information.

NI 7.4.0 supports the discovery of Radio Access Network (RAN) and Microwave (MW) devices on the network. It supports the modeling of these devices to produce physical and logical device hierarchies and create associations between them. It also detects discrepancies and reconciles data to synchronize inventory.

See Network Integrity RAN and MW FTP Cartridge Guide for more information.

NI 7.4.0 enables you to identify if a card takes up contiguous dual or triple slots in NMS when it performs discovery or import scan. You can achieve this by manually configuring your cartridge by using Service Catalog and Design - Design Studio. Once configured, the scan results reflect the correct slot usage details.

See Associating Contiguous Slots to a Card in Network Integrity Developer's Guide for more information.

You can now encrypt the values of SNMP V3 credentials stored in the database by using the EncryptDecryptUtil.jar utility. You can also decrypt values using the same utility by running it from the directory where Network Integrity is installed.

See Encrypt Decrypt Utility in Network Integrity System Administrator's Guide for more information.

NI 7.4.0 supports the discovery of physical and logical SDH entities from the network by using the SDH Discovery cartridge. This cartridge supports modeling of SDH connectivities such as topological links, trails, and tunnels. It can perform incremental discovery of SDH connectivities through notifications stored in the database.

See SDH Discovery Cartridge in Network Integrity FTP SDH Logical Resource Discovery and Assimilation Cartridge Guide for more information.

NI 7.4 supports importing of SDH connectivities from UIM, compares the imported UIM data with the discovered SDH connectivities and services, and reports any differences. It also resolves any discrepancies by correcting entities, associations, and attributes in UIM.

See SDH UIM Integration Cartridge in Network Integrity FTP SDH Logical Resource Discovery and Assimilation Cartridge Guide for more information.

NI 7.4 now supports the discovery and modeling of ODU, OTU, Och, OMS and OTS subnetworks within the DWDM network using the DWDM Logical Discovery Cartridge. It supports import of logical subnetworks from UIM, comparing this data with discovered subnetworks, and reconciling any discrepancies in the inventory.

See Network Integrity CORBA Based DWDM Layers and Service Discovery and Assimilation Cartridge Guide for more information.

NI 7.4.0 recognizes impacted physical or logical resources in SDH and DWDM networks based on device notifications. NI distinguishes the incremental changes in the data and updates device information, reducing extra effort when discrepancies are very small.

See Network Integrity FTP SDH Logical Resource Discovery and Assimilation Cartridge Guide and Network Integrity CORBA Based DWDM Layers and Service Discovery and Assimilation Cartridge Guide for more information.

You can now choose to run scans in an NMS and respective EMS of your choice. In NI 7.4.0, the scan parameter field on the user interface displays the list of available NMS values. Based on the NMS chosen, another field will appear from which you can choose the respective EMS to be scanned. Once the scan for the chosen EMS is complete, you can reset the scan parameters for other EMS to be scanned as well. This is a customization which can be manually added.

See Design Studio Modeling Network Integrity for more information.

The NI-UIM Integration web service now includes an ID that links reconciled entities with their corresponding PD, LD, Shelf, Card, Port or Interface. This improves discrepancy reconciliation by identifying the relationship between the reconciled entities and their sub-components.

See Network Integrity Optical UIM Integration Cartridge Guide for more information.

NI 7.4 supports the discovery and reconciliation of entities in IMS networks by using the IMS Discovery cartridge. It supports the modeling of devices in IMS networks, detects discrepancies between discovery scan results and data imported from UIM, and resolves the discrepancies.

See Network Integrity IMS FTP Discovery and UIM Integration Cartridge Guide for more information.

NI 7.4 supports the discovery and reconciliation of entities in DWDM networks by using the Optical FTP Discovery Cartridge. It supports the modeling of optical network devices in the DWDM networks, detects discrepancies between discovery scan results and data imported from UIM, and resolves the discrepancies.

See Network Integrity Optical FTP Discovery and UIM Integration Cartridge Guide for more information.
