14 Software Architecture

15 IOS-XR 6.X: A New Software Infrastructure 64-bit OpenEmbedded Linux support. Processes containerization. Standard Linux toolchain. Third-Party applications. NCS5500, NCS5000 and NCS1002 support 64-bit Linux. Classic XR XR 6.X System Control NPU System Admin 32 bit QNX Control 64 bit Linux Admin X86 Hardware ASR 9000 supports 64-bit Linux starting with Will still have 32-bit QNX support Cisco and/or its affiliates.

16 Introduction to Virtualization With exr, the Admin plane and the Control Plane run in isolated environment. ASR9K uses Virtual Machines (VMs) NCS5000 and NCS5500 use containers (LXCs) Provide the same functionalities Use same tools (libvirsh) to Provide the virtualization services LXCs are lightweight no ISSU support VMs are heavier but provide ISSU support NCS App App Lib Lib Operating System X86 Hardware ASR9K App App Lib Lib OS OS Hypervisor Operating System X86 Hardware 2018 Cisco and/or its affiliates. All rights reserved. Cisco Public 16

17 Why Virtualization? LXCs and VMs Provide HW abstraction Each instance has its own network interfaces - Can be bridged, routed... own filesystem - e.g.: RedHat host can run Debian container or Ubuntu VM. LXCs and VMs provide Isolation between instances Security - Two containers or VMs can't harm (or even see) each other. Resource usage - Soft & Hard quotas for RAM, CPU, I/O can be assigned on Containers or Vms 2018 Cisco and/or its affiliates. All rights reserved. Cisco Public 17

18 IOS-XR Entities Roles: The Host Runs Yocto based 64-bit Open Embedded Linux kernel. Built using Windriver 7 The main functions of the host are: Interact directly with the underlying hardware. Provide kernel services for the LXcs/VMs Provide libraries, tools, and utilities to help launch, monitor, and maintain containers. Provide the network infrastructure to allow containers to communicate. Control Plane Admin Plane Third Party 64-bit Host OS Routing Processor 2018 Cisco and/or its affiliates. All rights reserved.
