Timos-sr-13.0.r4-vm.qcow2 Updated

"Timos-sr-13.0.r4-vm.qcow2"

The file is a virtual disk image for the Nokia (formerly Alcatel-Lucent) 7750 Service Router (SR) operating system, known as TiMOS (Terabit Interactive Machine Operating System).

Basic QEMU Launch Command:

If you are running a Linux host with KVM enabled, you can spin this up directly. Here is a conceptual example of the command structure you might use: Timos-sr-13.0.r4-vm.qcow2

  • TiMOS: The acronym for Timra Operating System. Nokia’s inherited operating system from the former TiMetra (later Alcatel-Lucent). It powers the 7750 SR, 7950 XRS, and virtualized routing platforms.
  • sr: Stands for Service Router. This indicates the image is intended for the 7750 SR series of routing platforms (virtualized). There are alternate branches like sim (simulator, lower performance) or vprn (virtual private routed network), but sr is the full-feature routing stack.
  • 13.0: The major release version. Nokia’s TiMOS 13.0 introduced significant enhancements in Segment Routing (SR-MPLS and SRv6), EVPN, and automation (YANG models, gRPC).
  • r4: The revision or maintenance release. r4 is the fourth cumulative patch/hotfix bundle for the 13.0 major branch. It implies stability and bug fixes over prior revisions like r1 or r2.
  • vm: Explicitly identifies this as a Virtual Machine image (as opposed to a bare-metal installer for Nokia chassis).
  • qcow2: The QEMU Copy-On-Write version 2 format – the de facto standard for KVM (Kernel-based Virtual Machine) and OpenStack environments.
