nd and southbound APIs It gives an abstracted view of the complete networking environment. The power of NSO gives the ability to manage multivendor devices through a consistent southbound APIs which is not bound to any vendor product. It also helps to push the network configuration to the end devices vendor agnostically. Cisco network services orchestrator (NSO) core engine is responsible for all management including upgradation /downgradation, synchronization when maintaining high availability etc. It enables policy oriented capacity management to setup the use of policies and use of resources as per the organizational requirements and best practices and provides standard northbound and southbound Interfaces to the environment. NSO Core engines functionalities are summarized below: It handles upgrades and downgrades of software components. Maintain audit of the status changes and logs the changes in its database. It stores the configurations rollbacks. RBAC control can be enabled and used for more granular access to the infrastructure. AAA centralized engines for authentication management. NORTHBOUND APPLICATION PROGRAMMING INTERFACES Northbound APIs - CLI - NSO Specific, Graphical User Interface Downloaded: 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 NFV Practical Implementation Integration through Automation - REST(Representational state transfer), NETCONF etc. Monitor - NETCONF & SNMP Protocol (Monitoring of Cisco NSO). Primary Components of Cisco Network Service Orchestrator NETCONF: Device management Protocol. YANG: Service and device modeling Traditional network doesn't have a well defined management protocol to manage the underlying resources and meets the demands of the most demanding IT Organizations. Protocols like SNMP can be used as south bound APIs to manage the Infrastructure. However they lack features from scalability standpoint and is not a defined solution to manage the order of the configuration which is again relevant from the configuration & management perspect
