Descriptions: Version Manager (VM) is a new component in the Nova Operating System used as a baseline for all future version of the The Definition Language (TDL) compiler to track changes in behaviour, error messaging, etc. Nova Operating System is based on the open source Linux Operating System. Cisco IOS XE (Nova) represents the next evolution of Cisco IOS Software and extends IOS XE (BinOS) for other switching and routing products.

Job Duties and Responsibilities:

• Test Software Versioning triggering In-Service Software Upgrade (ISSU), Version Manager process, Service Point Infrastructure (SPI) based communication, checkpoint versioning and their messages and the TDL tooling, API testing, logging, events, traces, cpu and buffer and memory utilizations, stress, performance, scale, positive, negative cases and other scenarios.
• Test software in different hardware environments such as single Route Processors (RP), dual RPs and stacking platforms.

Descriptions: Redundancy Group Infrastructure provides extensible software redundancy infrastructure support to applications such as Cloud, IoT, Firewalls, IPSec VPN, and NAT. It works along with hardware box-to-box redundancy and integrates well with other infrastructure system components. It provides application high availability through many techniques such as redundancy, check pointing, synchronization, etc and guarantees investment protection of key infrastructure elements for customers for their continued business operations.
