Network Functions Virtualization can enable each user (tenant) to define his desired set of network services, called (network) service graph. For instance, a User1may want his traffic to traverse a firewall before reaching his terminal, while a User2 may be interested in a different type of firewall and in a network monitor as well. This paper presents a prototype of an SDN-enabled node that, given anew user connected to one of its physical ports, it is able to dynamically instantiate the user's network service graph and force all his traffic to traverse the proper set of network functions.

In software defined networking (SDN), a controller acts as the "brain," providing a centralized view of the whole network. Through the controller, the network can be quickly and easily programmed and managed. Consequently, the importance of an SDN controller's performance is significant. In SDN controllers, high performance has two aspects: fast response time, and high flow-setup rate. In this paper, we present a high-performance IO engine that gives at least a 26% higher flow-setup rate than current state-of-the-art controllers while maintaining the fastest response time. The IRIS IO engine adopts a multi-queue design, which is fundamentally different from the other controllers' approaches. Further, our evaluation results show that the IRIS IO engine has the best processing-core scalability among the fastest open-source controllers.

The rise of cloud services poses considerable challenges on the control of both cloud and carrier network infrastructures. While traditional telecom network services rely on rather static processes (often involving manual steps), the wide adoption of mobile devices including tablets, smartphones and wearables introduce previously unseen dynamics in the creation, scaling and withdrawal of new services. These phenomena require optimal flexibility in the characterization of services, as well as on the control and orchestration of both carrier and cloud infrastructure. This paper proposes a unified programmability framework addressing: the unification of network and cloud resources, the integrated control and management of cloud and network, the description for programming networked/cloud services, and the provisioning processes of these services. In addition proofs-of-concept are provided based on existing open source control software components.

Network Functions Virtualization (NFV) aims to transform network functions into software images, executed on standard, high-volume hardware. This paper focuses on the case in which a massive number of (tiny) network function instances are executed simultaneously on the same server and presents our experience in the design of the components that move the traffic across those functions, based on the primitives offered by the Intel DPDK framework. This paper proposes different possible architectures, it characterizes the resulting implementations, and it evaluates their applicability under different constraints.

In this paper we consider carrier networks using only OpenFlow switches instead of IP routers. Accommodating the full forwarding information base (FIB) of IP routers in the switches is difficult because the BGP routing tables in the default-free zone currently contain about 500,000 entries and switches have only little capacity in their fast and expensive TCAM memory. The objective of this paper is the compression of the FIB in acceptable time to minimize the TCAM requirements of switches. The benchmark is simple prefix aggregation as it is common in IP networks where longest-prefix matching is applied. In contrast, OpenFlow-based switches can match general wildcard expressions with priorities. Starting from a minimum-size prefix-based FIB, we further compress that FIB by allowing general wildcard expressions utilizing the Espresso heuristic that is commonly used for logic minimization. As the computation time of Espresso is challenging for large inputs, we provide means to trade computation time against compression efficiency. Our results show that today's FIB sizes can be reduced by 17% saving up to 40,000 entries and the compression time can be limited to 1 - 2s sacrificing only 1% -- 2% compression ratio.
在本文中，我们考虑仅使用OpenFlow交换机而不是IP路由器的运营商网络。由于目前缺省区域内的BGP路由表大约有50万项，而交换机的TCAM内存又快又贵，因此在交换机中容纳IP路由器的全部FIB (forwarding information base)是很困难的。本文的目标是在可接受的时间内压缩FIB，以最小化交换机的TCAM要求。该基准是简单的前缀聚合，因为它在应用最长前缀匹配的IP网络中很常见。相反，基于openflow的开关可以用优先级匹配通用通配符表达式。从最小大小的基于前缀的FIB开始，我们进一步压缩FIB，允许使用通常用于逻辑最小化的Espresso启发式的通用通配符表达式。由于Espresso的计算时间对大输入具有挑战性，我们提供了以计算时间和压缩效率为代价的方法。我们的结果表明，今天的FIB大小可以减少17%，节省多达40,000个条目，压缩时间可以限制在1 - 2s，仅牺牲1% - 2%的压缩比。

The possibility to deploy telecommunication services based on the availability of a fully flow-aware network is an appealing possibility. Concepts like Network Service Chaining and Network Function Virtualization expect the information to be manageable at the flow level. But, for this concept to be available for the development of user-centric applications, the access network should also be made flow-aware. In this paper we present the integration of a legacy DOCSIS based access network under an OpenFlow Control Framework by using the Hardware Abstraction Layer designed in the FP7 ALIEN project. The result is a dynamic wide area OpenFlow switch that spawns from the aggregation switch to the home equipment and hides all the complexity (including the provisioning) of the access technology to an unmodified and standard OpenFlow controller. As a result, the access network can react not only to any kind of user traffic but also to the connection of CPE to the network. The approach used is technology independent, and the results have been successfully demonstrated over a Cisco based DOCSIS access network.

Network service chaining allows composing services out of multiple service functions. Traditional network service functions include, e.g., firewalls, TCP optimizers, web proxies, or higher layer applications. Network service chaining requires flexible service function deployment models. Related work facilitating service chaining include, e.g., the network service header proposal discussed at the IETF or the complementary work on network function virtualization (NFV) at ETSI. This position paper presents a high-level concept and architecture to enable service chaining using Software Defined Networking (SDN), specifically OpenFlow in a telecommunication environment. The paper discusses required functionalities, challenges, and testbed aspects to implement and test such an approach. Finally, the set of implemented service functions and management interfaces are highlighted to demonstrate the approach as a proof of concept for a selection of relevant use cases.
