Control and Forwarding Plane Interaction in Distributed Routers
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 packe...
متن کاملControl and forwarding-plane separation of an open-source router
In previous work[1-3] it has been shown how open-source routers on new PC hardware allows for forwarding speeds of 10Gb/s and above. In this work we extend the applicability of the results by showing how the new 10Gb/s interface classification techniques can be used to separate packet forwarding from control plane operation. It is important to isolate the control-plane from forwarding load, sin...
متن کاملCoherent SDN Forwarding Plane Programming
the actions associated with each flow entry as a piece of program. This allows us to decouple the match keys and actions. The actions can be downloaded to FEs separately in the form of instruction blocks. A flow entry only needs to include a block ID to infer the associated instruction block. By doing so, different flow entries can share the same instruction block, and there is theoretically no...
متن کاملNext Generation Routers
As the broadband access technologies, such as DSL, cable modem, and gigabit Ethernet, are providing affordable broadband solutions to the Internet from home and the enterprise, it is required to build next generation routers with high-speed interfaces (e.g., 10 or 40 Gb/s) and large switching capacity (e.g., multipetabit). This paper first points out the issues of building such routers, such as...
متن کاملData Plane Optimization in Open Virtual Routers
A major challenge in network virtualization is to virtualize the components constituting the network, in particular the routers. In the work presented here, we focus on how to use open source Linux software in combination with commodity hardware to build open virtual routers. A general approach in open router virtualization is to run multiple virtual instances in parallel on the same PC hardwar...
