Red Hat Enterprise Linux 7 上でのDockerのステータス、使い方の解説と、Project Atomicをはじめとして、CentOS Atomic Host, RHEL Atomic Hostの解説。CentOS Atomic HostでKubernetesを使うチュートリアル。
This document summarizes a CDP indicator device created with a Raspberry Pi. The device displays information about connected devices that it receives from CDP packets on its Ethernet interface. It also sends its own device information via CDP. The device uses SCAPY to receive and generate CDP packets. It can be connected to LittleBits Cloudbit devices and controlled via the Cloudbit web API or integrated with other web services using IFTTT.

- The document discusses Network Services Orchestrator (NSO) and provides an overview of NSO architecture and concepts.
- NSO uses a model-driven approach to automate network configuration and service orchestration across multiple network devices from different vendors. It provides northbound APIs to allow programmatic control and abstraction of network services.
- NSO's architecture includes components like the Configuration Database (CDB) for storing configuration models, Device Manager for network device configuration management, and Service Manager for abstracting and mapping services to device models.
The document discusses using Ixia's IxVM virtual machine for network testing in Cisco's Modeling Lab (CML) virtual environment. Specifically:
- IxVM is a virtual machine version of Ixia's network testing hardware that runs on Linux. Its OVA file can be added to CML.
- The OVA file contains disk files that are extracted and registered with CML's OpenStack environment to launch the IxVM VM.
- Example shows configuring a router and IxVM VMs in CML, and using IxNetwork software to generate OSPF traffic between the VMs and router ports for testing.
