Zero touch inventory (zti) as part of operation support system (oss) in future networks
CA 2451947 A1
Operation Support System (OSS) is a set of programs that help a communications service provider monitor, control, analyze, and manage problems with a telephone or data network. Inventory Management Systems such as Granite's Xng or Cramer's Dimension helping service providers to keep track of their assets in their network, to improve their service delivery and last but not least to provision a new service for customers. Standard products in Inventory space require an implementation/modeling-phase of an existing network any where between 6 to 9 months. Also an accuracy of data is not always guaranteed, since there is always a discrepancy between the modeling and the planning organization.
In this invention the inventory module is not to be fed with data from existing network. It rather scans the network and poll the information out of the network. Once the information is gathered from the network, some smart algorithms needs to be run, in order to put the data together and get a meaningful inventory system. Since the data is always updated from network (network driven update vs. manually), the data stored is always accurate.
1. A process for Operation Support System (OSS) auto-reconciliation of network inventory system without manual interference of human being for IP and MPLS based networks. In this process not only the hardware data can be gathered and modeled, furthermore the logical services can be inventoried. The modeling phase does not require an implementation phase (Zero-Touch-Inventory)
2. A process as defined in claim 1, in which the inventory data can be gathered without manual interaction, supports for an on-demand-reconciliation of the modeled data and real data in the network (network driven vs. modeled).
3. The process as defined in claim 1 will be supported by the Rule Based Engine. It is an algorithm based on fuzzy-logic pattern recognition, which is able to automatically consolidate the network driven gathered data and build the inventory data.
Description  (OCR text may contain errors)

Right now the two biggest OSS inventory leaders of the market Granite and Cramer need more than 6 months to implement their projects in Tier-1 environment. Most of the time is being consumed by data validation and take over of existing data in the new environment. After the implementation the data needs to be kept accurate. For this purpose most of the companies have such a synchronization tool, which tries to keep the data up to date (ca. 70%). Other companies are able to feed the inventory system with accurate data out of network with regards to Chassis Cards Ports Power supplies Fans Hardware, software and firmware Logical service components .
Hereby the emphasis is still the physical asset management. The support for logical service is built rudimentary. In reality such an extended project for auto-reconciliation would take another 3 months to get implemented.
The described scenario would apply for old fashioned SDHISONET networks. As most companies are moving toward IP based network in a fully dynamic environment, the mentioned scenario is getting more complex. The modeling phase is not a one-time approach, rather than ongoing.
The auto-reconciliation is ideally being run once-a-day.
The Zerp-Touch Inventory is a fully automated, 1009 zero-error-prone approach, to model the inventory data based on the data fed directly by the network. There is no human interaction required in order to keep the data loaded out of the network(s). The data will be gathered and then compiled in order to generate new data e.g. to see who is running VoIP from node A to node Z. This approach is not only covering ISO/OSi model Layer1 to Layer 3, but furthermore the application layer. As situation changes rapidly in dynamic IP environment, a smart rule based engine needs to be developed to compile the data constantly and provide the user with up to date and accurate data. The rule based engine needs to be self configurable in order to minimize the maintenance cost.
Zero-Touch inventory ultimately will provide the user with an exact snapshot of the current configuration of the network(s).
The sources to load data out of networks) could be the following:
- Telnet module o Queries data from IOS-based Cisco equipments - Corba module o Queries data from Cisco VPN SC
o Receives notifications from Cisco VPN SC
- SNMP module o Queries data from SNMP-based equipments o Receives traps from equipments HP OpenVisw Once the data are loaded and compiled into useful inventory data, a complete path consisting of equipment, links in between can be displayed and visualized. The following example explains the goal of the invention. In the frgure 2 a simple network consisting of 4 Cisco 15414 network is displaced.
Furthermore we assume that Cisco 7502 Router is being used to transfer IP
networks directly this backbone. In this case the Zero-Touch-Inventory module v~rould capture the equipment with regards to chassis, cards, ports. The MPLS LSP (Label Switching Paths, the logical services) are then gathered in the next step. Once all the information is gathered, the Rule Based Engine can be run to sort the data and build the inventory output data. The data flow is being shown in the figure 3.
