Previous research shows that adding SDN capabilities to switches at strategic places in a network and ensuring that each flow traverses at least one such switch is sufficient to achieve many SDN control paradigms, such as routing or access control. However, the control points are still limited to the SDN-enabled devices and operators cannot enforce fine-grained policies on the legacy paths between SDN switches. We present Telekinesis, a network controller that enables finer-grained routing control over legacy paths in hybrid networks using OpenFlow. To update routing entries in legacy switches, we introduce a new flow control primitive, LegacyFlowMod. LegacyFlowMod uses OpenFlow's PacketOut function to send a special packet on a specific interface of a legacy switch and remotely manipulate the forwarding entry associated with the source of the packet. Using simulations on random network topologies with varying degrees of OpenFlow deployment, we show that Telekinesis can provide more diverse path control than an OpenFlow-only controller: even when only 20% of switches are OpenFlow-enabled, we can update 70% of the paths.","PeriodicalId":316190,"journal":{"name":"Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121310697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In today's networks, it is challenging to get accurate and timely traffic matrix due to the hard resource constraints of network devices. Recently, Software-Defined Networking (SDN) technique enables customizable traffic measurement, which can provide flexible and fine-grain visibility into network traffic. However, the existing software-defined traffic measurement solutions often suffer from feasibility and scalability issues. In this paper, we seek accurate, feasible and scalable traffic matrix estimation approaches. We propose two strategies, called Maximum Load Rule First (MLRF) and Large Flow First (LFF), to design feasible traffic measurement rules that can be installed in TCAM entries of SDN switches. The statistics of the measurement rules are collected by the controller to estimate fine-grained traffic matrix. Both MLRF and LFF satisfy the flow aggregation constraints (determined by associated routing policies) and have low-complexity. Extensive simulation results on real network and traffic traces reveal that MLRF and LFF can achieve high accuracy of traffic matrix estimation and high probability of heavy hitter detection.","PeriodicalId":316190,"journal":{"name":"Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125855394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This requires performing route optimization, in real time and across a diverse choice of paths. A large variety of techniques have been proposed to provide path diversity for network fabrics. But, running up against the constraint of forwarding table size, these proposals are topology-dependent, complex, and still only provide limited path choice which (we show) can impact performance. We propose a simple approach to realize the vision of a flexible, high-performance fabric: the network should expose every possible path, allowing a controller or edge device maximum choice. To this end, we observe that source routing can be encoded and processed compactly into a single field, even in large networks, with OpenFlow 1.3. We show that, in addition to the expected decrease in required forwarding table size, source routing supports optimal throughput performance, in some cases significantly higher than some past proposals. We thus believe source routing offers a clean abstraction and efficient implementation for future network fabrics.","PeriodicalId":316190,"journal":{"name":"Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127228738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underlay network infrastructure has to scale to support tens of millions of physical endpoints at low cost; the virtualized overlay layer has to scale to millions of Virtual Networks connecting hundreds of millions of Virtual Machines (VMs) and Virtualized Network Functions (VNFs), and provide seamless VM and VNF mobility. In this paper, we present Hierarchical SDN (HSDN), an architectural solution that achieves hyper scale using surprisingly small forwarding tables in the network nodes. HSDN introduces a new paradigm for the forwarding and control planes, in that all paths in the network are pre-established in the forwarding tables and the labels identify entire paths rather than simply destinations. These properties of HSDN dramatically simplify establishing tunnels, and thus enable optimal handling of both ECMP and any-to-any end-to-end TE, which in turn yields extremely high network utilization with small buffers in the switches. The pre-established tunnels make HSDN the ideal underlay infrastructure to enable seamless and lossless VM and VNF overlay mobility, and achieve excellent elasticity. HSDN is suitable for a full SDN implementation, using a scalable SDN controller to configure all forwarding tables in the network nodes and in the endpoints, as well as a hybrid approach, using conventional routing protocols in conjunction with a SDN controller.","PeriodicalId":316190,"journal":{"name":"Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129970337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These approaches make it difficult to reuse functionality across different packet processing elements and also do not use available in-network processing resources efficiently. We present Slick, a framework for programming network functions that allows a programmer to write a single high-level control program that specifies custom packet processing on precise subsets of traffic. The Slick runtime coordinates the placement of fine-grained packet processing elements (e.g., firewalls, load balancers) and steers traffic through sequences of these element instances. A Slick program merely dictates what processing should be performed on specific traffic flows, without requiring the programmer to specify where in the network specific processing elements are instantiated or how traffic should be routed through them. In contrast to previous work, Slick handles both the placement of fine-grained elements and the steering of traffic through specific sequences of element instances, allowing for more efficient use of network resources than solutions that solve each problem in isolation.","PeriodicalId":316190,"journal":{"name":"Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116883591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
