OpenNF: enabling innovation in network function control
Aaron Gember-Jacobson,Raajay Viswanathan,Chaithan Prakash,Robert Grandl,Junaid Khalid,Sourav Das,Aditya Akella +6 more
TL;DR: This work designs a control plane called OpenNF that uses carefully designed APIs and a clever combination of events and forwarding updates to address race conditions, bound overhead, and accommodate a variety of NFs.
Proceedings ArticleDOI
PGA: Using Graphs to Express and Automatically Reconcile Network Policies
Chaithan Prakash,Jeongkeun Lee,Yoshio Turner,Joon-Myung Kang,Aditya Akella,Sujata Banerjee,Charles F. Clark,Yadi Ma,Puneet Sharma,Ying Zhang +9 more
TL;DR: This work first develops a high-level Policy Graph Abstraction (PGA) that allows network policies to be expressed simply and independently, and leverage the graph structure to detect and resolve policy conflicts efficiently, and also models and composes service chaining policies.
Proceedings ArticleDOI
Measuring control plane latency in SDN-enabled switches
Keqiang He,Junaid Khalid,Aaron Gember-Jacobson,Sourav Das,Chaithan Prakash,Aditya Akella,Li Erran Li,Marina Thottan +7 more
TL;DR: The authors' measurements show that control actions, such as rule installation, have surprisingly high latency, due to both software implementation inefficiencies and fundamental traits of switch hardware.

Network policy graphs
Junggun Lee,Chaithan Prakash,Charles F. Clark,David Lenrow,Yoshio Turner,Sujata Banerjee,Puneet Sharma,Yadi Ma,Joon-Myung Kang +8 more
TL;DR: In this article, the authors proposed a method to generate composite network policy graphs based on multiple network policy graph input by network users that may have different goals for the network, which can be used to program a network so that it meets the requirements necessary to achieve the goals of at least some of the network users.
Proceedings ArticleDOI
Latency in Software Defined Networks: Measurements and Mitigation Techniques
Keqiang He,Junaid Khalid,Sourav Das,Aaron Gember-Jacobson,Chaithan Prakash,Aditya Akella,Li Erran Li,Marina Thottan +7 more
TL;DR: This work conducts a comprehensive measurement study of switch control plane latencies using four types of production SDN switches and proposes three measurement-driven latency mitigation techniques to effectively tame the flow setup latencies in SDN.
