XR7, Not Just Another Release

When IOS XR was first designed, mass-scale networking and its related challenges were not around.  However, we already had a clear vision of building a highly scalable, reliable, available, upgradeable, high-performance NOS for the service provider space that caters all the way from low-end single chassis systems to massive high-end multi-chassis routers. To meet the rigorous SP requirements, a slew of ground-breaking infrastructure and distributed-systems architecture patterns were brought into the system—decoupled plane abstractions, state management, process distribution, high-performance messaging infrastructure, data distribution/access patterns, high availability and upgradeability. These solid foundations and continuous evolutions made IOS XR the industry-leading NOS.I’m thrilled to announce today the availability of IOS XR, Release 7, that brings some noteworthy evolutions. Four key tenets make Release 7 stand out.It is simple, modern, trustworthy, and cloud-enhanced.
