Wanted: Systems Abstractions for SDN
نویسندگان
چکیده
This paper presents a case for applying the principles of Software-Defined Networking (SDN) to middleboxes and end hosts. The challenges of configuring networking on network hosts resemble those addressed by SDN – numerous multi-vendor components, each with its own syntax and idiosyncratic corner cases, must be orchestrated smoothly. We have developed a prototype called NativeClick, a novel use of the Click Modular Router language, to orchestrate Linux networking tools. NativeClick demonstrates that, while existing SDN efforts have produced insufficient Abstractions to cover a wide range of networking behavior, SDN-like abstractions can make host configurations modular.

Enabling Dynamic Reconfigurability of SDRs Using SDN Principles
Dynamic reconfiguration and network programmability are active research areas. State of the art solutions use the Software Defined Networking (SDN) paradigm to provide basic data plane abstractions and programming interfaces for control and management of these abstractions; however, SDN technologies are currently limited to wiredions; however, SDN technologies are currently limited to wired net...
متن کاملModular SDN Programming with Pyretic
Managing today’s computer networks is a complex and error-prone task. These networks consist of a wide variety of devices, from routers and switches, to firewalls, network-address translators, load balancers, and intrusion-detection systems. Network administrators must express policies through tedious box-by-box configuration, while grappling with a multitude of protocols and baroque, vendor-sp...
متن کاملSDN Security: A Survey
The pull of Software-Defined Network- ing (SDN) is magnetic. There are few in the networking community who have escaped its impact. As the benefits of network visibility and network device programmability are discussed, the question could be asked as to who exactly will benefit? Will it be the network operator or will it, in fact, be the network intruder? As SDN devices and systems hit the mark...

متن کاملFast failure detection and recovery in SDN with stateful data plane
When dealing with node or link failures in SoftwareDefined Networking (SDN), the network capability to establish an alternative path depends on controller reachability and on the round-trip times (RTTs) between controller and involved switches. Moreover, current SDN data plane abstractions for failure detection, such as OpenFlow “Fast-failover”, do not allow programmers to tweak switches’ detec...
