Software-Defined Networking (SDN) is one of the possible solutions, to which telecommunication industry is moving. This work presents current state-of-the-art in Software-Defined Networking and focuses on some open-source solutions of SDN controllers, like ONOS and OpenDaylight. Main focus is to understand how SDN can help to solve increasing demand for broader automa- tion in Optical Transport Networks. The practical section is divided in two parts. Within the first part I focused on extending functionality of SDN controller to facilitate more efficient configuration and control of optical network devices. Main contribution was to implement additional features to SDN drivers for Nokia 1830 PSS (ROADM) and extend functionality of Nokia 1830 PSI-2T (Optical Transponder) driver. Second part is dedicated to the Alarm Correlation problematic in open optical networks. We designed, developed an Alarm Correlation function as a SDN application then we tested it on emulated optical devices to prove the concept. Keywords: Software-Defined Networking, SDN, NETCONF, OPENCONFIG, Open Network Operating Systems, ONOS 2.x, ODTN, Open and Disaggregated Transport Net- work, Open Optical Transport Networks, Optical Transponder, ROADM, Reconfigurable Add/Drop Multiplexer, Future Networks, Alarm Correlation, Alarm Localization.

En cons´equence,les solutions de contr^oleexistantes pour offrir des services de connectivit´edoivent ^etrereconsid´er´ees. Les approaches orient´eeslogicielles "Software- Defined Networking" dites (SDN) sont les solutions de contr^olepossibles pour les r´eseaux t´el´ecomque les op´erateursanalysent actuellement en d´etails.

Recently surpassing the 50-member milestone, the fast-growing ONOS community is also rapidly diversifying. In just one year, the project went from one to five service provider partners and six to eight vendor partners. Additionally, more than 250 registered users are making code software updates. ONOS has quickly established an active community of contributors, members and production use cases, emerging as a leading SDN OS among services providers. These developments, as well as the sixth ONOS platform release, will be showcased at The Linux Foundation-hosted Open Networking Summit and ONOS Mini Summit taking place in Santa Clara, Calif., March 14-17, 2016. "ONOS new member and community growth are pivotal in accelerating adoption of SDN and NFV," said Guru Parulkar, executive director and board member at ON.Lab's ONOS project. "ONOS has evolved so quickly, emerging as the SDN OS of choice by service providers and the foundation for numerous successful use cases such as CORD, packet-optical convergence, SDN-IP peering, and others.

  • ONOS: SDN Gets Real / Expert's Forum
    ONOS: SDN gets real / Expert's Forum ONOS: SDN gets real The future of telco is software-defined; it’s also open-source. Open Network Operating System (ONOS) is the first carrier-grade operating system that combines both. ONOS is the brainchild of ON.Lab, and its Executive Director, Guru Parulkar, recently sat down with Communicate to discuss the platform itself, the state of SDN in the industry, and the shifting role of telcos. Guru Parulkar Executive Director of ON. Lab It’s no longer academic ommunicate: Tell us a bit about the background of ON.Lab and ONOS. Guru Parulkar: SDN started Coriginally at Stanford University and UC Berkeley. We did a number of things with SDN, including building SDN controllers and OpenFlow-based switches. Three years ago, we started to see that SDN was taking off and the industry was becoming serious about SDN. So at that time, we realized that the industry would need open-source SDN platforms, the use of which can build real products and solutions. To accelerate SDN, we started Open Networking Lab (ON.Lab) as an independent, non-profit networks. What that means is that ONOS is organization to create open-source SDN designed to be scalable, high-performance, platforms and tools for the industry to use and highly available, and has the right kind of build on. abstractions, so network DevOps personnel can As for ONOS, it is, in some way, our write applications and services on top of ONOS first significant open-source SDN platform. It very easily. is an open-source network operating system When we started ON.Lab, SDN was already that is primarily designed for service provider starting to happen in data centers.
