Control and Forwarding Plane Interaction in Distributed Routers

چکیده
The requirements on IP routers continue to increase, both from the control plane and the forwarding plane perspectives. To improve scalability, flexibility, and availability new ways to build future routers need to be investigated. This paper suggests a decentralized, modular system design for routers, based on control elements for functionalities like routing, and forwarding elements for packet processing. Further, we present measurements on the distribution of large routing tables in an experimental platform consisting of one control element and up to 16 forwarding elements.

On the Design of Next-Generation Routers and IP Networks
This thesis investigates distributed router architectures and IP networks with centralized control. While the current trend in IP-router architectures is towards decentralized design, there have also been research proposals for centralizing the control functions in IP networks. With continuous evolution of routers and IP networks, we believe that eventually IP networks in an autonomous system (...
متن کاملService Characterization for Virtual Routers
In the past decade the virtualization paradigm has been remarkably successful in the server domain, and significant benefits are expected from the virtualization of network resources. However, to date the virtualization capabilities of proprietary systems remain limited while the impact of executing open software routers within system virtualization platforms has not been fully investigated. In...
متن کاملRefactoring Network Control and Management: A Case for the 4D Architecture
We argue for the refactoring of the IP control plane to support network-wide objectives and control. We put forward a design that refactors functionality into a novel 4D architecture composed of four separate planes: decision, dissemination, discovery and data. All decision-making logic is moved out of routers along with current management plane functions to create a logically centralized decis...
متن کاملAn Integrated Network Resource and QoS Management Framework
We present an integrated network resource and QoS management framework based on the idea of decoupling the network control plane from the data plane. Our framework is capable of providing perflow QoS guarantees using scalable core-stateless packet forwarding mechanism at the network core. Virtual Time Reference System provides the abstraction of the data plane. Bandwidth broker performs all con...
متن کاملNeural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks
Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...
