![]() The NSO transactional engine can drive the NEDs to do atomic changes and rollback on failure, even when a device has no native support for transactions. NSO NEDs also provide transactionality for nontransactional devices.Uniform data model across the network: Across the NSO interfaces and APIs, it appears as though all devices support YANG, although the underlying mechanism can be CLI or REST, for example.In this case there is no charge for the NED, so integration is free! If the device offers a NETCONF/YANG interface then no development is required, as the NED can be generated automatically from the device model.This may however vary with the size and complexity of the configuration. Typically adding new commands to an existing NED takes a couple of weeks, and creating a new NED takes six to eight weeks. ![]() In NSO, however, the NEDs are rendered from a YANG data model that can automatically generate the corresponding commands, such as CLI commands. Drastically shortened development and update cycles: In other systems, adaptors are normally handcrafted.They communicate over the native protocol supported by the device, such as Network Configuration Protocol (NETCONF), Representational State Transfer (REST), Extensible Markup Language (XML), CLI, and Simple Network Management Protocol (SNMP).ĭrivers are rendered based on a Yet Another Next Generation (YANG) data model, which provides several benefits: Network element drivers comprise the network-facing part of NSO. ![]() In addition, NSO services, like VPN, can configure a complex multivendor network. ![]() Using NEDs, NSO makes device configuration commands available over a network wide, multivendor Command Line Interface (CLI), APIs, and user interface. Cisco NSO NEDs, in contrast, are either generated automatically from the device YANG model, or can add new commands and devices in a matter of weeks. Traditionally, device adaptors are a major roadblock, since they cannot be upgraded at the same pace as device interfaces, and adding support for new devices can take months. To offer support for an exceptional range of multivendor devices, it uses Network Element Drivers (NEDs). Exceptional Multivendor Support through Network Elements DriversĬisco ® Network Services Orchestrator (NSO) provides a single pane of glass for orchestrating a multivendor network. ![]()
