LCN - SDN shim: Controlling Legacy devices
2015 IEEE 40th Conference on Local Computer Networks (LCN), 2015Co-Authors: Daniel J. Casey, Barry E. MullinsAbstract:We propose a design to aid experimentation with SDN architectures using Legacy Network equipment. We implement a portion of the design on an FPGA and evaluate throughput and latency. Results indicate viability for testbed and research environments, especially with proposed additions to further reduce latency in broadcast- and multicast-heavy traffic.

integrating Legacy forwarding environment to openflow sdn control plane
Asia-Pacific Network Operations and Management Symposium, 2013Co-Authors: Fernando Farias, João J. Salvatti, Pedro Victor, Antônio J. G. AbelémAbstract:Currently, there is a philosophical problem that arises between the real need for current support to OpenFlow and Legacy Network infrastructure. Among them, the Legacy Networking has not been compatible with OpenFlow Network, and for that, it needs to be replaced or a few cases upgraded, as a consequence there are additional spending with new equipment OpenFlow-based. This paper introduces a proposal of hybrid SDN solution based on OpenFlow protocol and called of LegacyFlow, which is able to control Legacy equipment (non-OpenFlow) through OpenFlow protocol 1.0. Results show that it is possible used the LegacyFlow together with OpenFlow switches keeping a good performance time with OpenFlow application.

A proposal management of the Legacy Network environment using OpenFlow control plane
2012 IEEE Network Operations and Management Symposium, 2012Co-Authors: Fernando N. N. Farias, João J. Salvatti, Eduardo C. Cerqueira, Antônio J. G. AbelémAbstract:The Future Internet will arise from the convergence of new Network concepts and combine technologies, services, media and content. It will offer flexibility and diversity with scalable content and services that are accessible through a wide range of interfaces and devices. However, the biggest challenge now is how to enable and test the proposed approaches so that they can be validated without sacrificing the current production infrastructure. The OpenFlow protocol allows production Networking environments such as campus Networks, metropolitan Networks or R&D Networks, to be used as experimental infrastructure hosting, future Internet architectures, software and protocols, in parallel with the production traffic. During rollout, there is a practical problem that arises with Legacy Networks that do not support OpenFlow and need to be replaced/upgraded or refined by means of costly Network re-engineering. This paper proposes a new OpenFlow architecture with new components, capable of managing Legacy-non-OpenFlow elements by offering a new solution that facilitates the management of Legacy technologies and allows them to be employed in FI experimentation environment and increase the number of experiment with the Legacy Network Environment using OpenFlow control.

Introducing TMN into a Legacy Network is generally an uphill battle. This article provides a critical review of the two key approaches used in the industry for introducing TMN interfaces into Legacy Networks. Approaches for Introducing TMN in Legacy
1996Co-Authors: R.h. Glitho, Ericsson Canada, S. HayesAbstract:he lelecommunications management Network (TMN) / principles [l] aim at the operation, administration, maintenance, and provisioning (OAMP howevcr, vcry fcw installed elements support these interfaces. For introducing TMN in Networks where the elements do not support the interfaces specified in standards, two chief approaches are used in the industry. The approach called bottom-up in this article is rooted in the TMN principles as defined today. It consists of replacing the Legacy OAM&P interfaces of the Network with TMN interfaces. These new interfaces usually provide all the functionality one could possibly ever need in an OAM&P process. Although this rich functionality is to be used in the OAMBrP process, the specific use made of it remains an implementation matter and is of no concern to the standards. Once the interfaces are in place, the operation systems (0%) are supposed to exploit the new functionality as much as needed. The approach called top-down in this article has its roots in the process reengineering that is occurring throughout the telecommunications industry. In this approach specific objectives are targeted. Examples of Objectives are quality of service (QoS) assessment and traffic analysis. Using process reengineering methods, the functionality needed at the interfaces to support the objectives is determined. TMN interfaces which provide this functionality are then introduced in the Network. In this case, thc TMN interfaces introduced may coexist with the existing Legacy OAM&P interfaces and provide the additional functionality needed. This article provides a critical analysis of the two approaches used in the industry for introducing TMN in Legacy Networks. Before the analysis, it is of prime importance to establish some ground rules. There is currently no common understanding of what introducing TMN into a Legacy nctwork means, as there is no common understanding of what introducing TMN into a Network means. We start this article by analyzing what introducing TMN into a Legacy Network means, and then study, successively, the bottom-up and topdown approaches. Finally, a cost trade-off analysis is made.

SDN/Legacy Hybrid Network Control System
2019 Eleventh International Conference on Ubiquitous and Future Networks (ICUFN), 2019Co-Authors: Feliksas Kuliesius, Mindaugas GiedraitisAbstract:The widespread replacement of traditional Network to SDN is still restricted in the enterprise environment, and hybrid Network where SDN and Legacy Network appliances coexist by necessity complementing each other is deployed usually. To answer the Network parts integration issues, the hybrid Network control system is developed and discussed in the present work. Thorough Network topology assessment (BDDP complemented with LLDP/SNMP based Legacy Network discovery) and the possibility of converting SDN flow rules into the configurations of Legacy appliances enables to orchestrate hybrid Network as well as to enforce the Network security.
