• ### Cutting Long-Tail Latency of Routing Response in Software Defined Networks

Publication Year: 2018, Page(s):384 - 396
| | PDF (2041 KB) | HTML

To enable the network softwarization, network function virtualization (NFV) and software defined networking (SDN) are integrated to jointly manage and utilize the network resource and virtualized network functions (VNFs). For a network flow resulting from any NFV application, an associated switch would send a routing request to the controller in SDN. The controller then generates and configures a ...

• ### Joint Virtual Switch Deployment and Routing for Load Balancing in SDNs

Publication Year: 2018, Page(s):397 - 410
| | PDF (2743 KB) | HTML

To better serve a diversity of flows, load balancing is crucial to ensure operational efficiency. However, previous works for load balancing have several disadvantages: 1) limited applicability with sub-flow scheduling (e.g., LetFlow); 2) hash collision (e.g., ECMP); or 3) transient network congestion due to reactive scheduling for traffic dynamics (e.g., Hedera and DevoFlow). An important reason ... View full abstract»

Publication Year: 2018, Page(s):411 - 421
| | PDF (3723 KB) | HTML

Software defined network (SDN) provides flexible and scalable routing by separating control plane and data plane. With centralized control, SDN has been widely used in traffic engineering, link failure recovery, and load balancing. This work considers the flow update problem, where a set of flows need to be migrated or rearranged due to change of network status. During flow update, efficiency and ... View full abstract»

| | PDF (3546 KB) | HTML

Characterizing a virtual network function performance is one of the most challenging issues in softwarized network function deployment due to different configurations leading to a different performance. Since there has been no clear solution on how to configure a software router that provides the minimum average packet latency, we address this problem by proposing a configuration framework for a s...

• ### Virtual Network Survivability Through Joint Spare Capacity Allocation and Embedding

Publication Year: 2018, Page(s):502 - 518
| | PDF (2049 KB) | HTML

A key challenge in network virtualization is to efficiently map a virtual network (VN) on a substrate network (SN), while accounting for possible substrate failures. This is known as the survivable VN embedding (SVNE) problem. The state-of-the-art literature has studied the SVNE problem from infrastructure providers' (InPs') perspective, i.e., provisioning backup resources in the SN. A rather unex... View full abstract»

| | PDF (1048 KB) | HTML

The evolution towards 5G consists of managing highly dynamic networks and making decisions related to the provisioning of networks in an as-a-service and cost-aware fashion. This is translated by 5G verticals that are dedicated to specific services, applications, or use cases fulfilling the constant demand of vertical industries. In this vein, to achieve the high-level goals defined by operators a... View full abstract»

• ### A Scalable Approach for Service Chain Mapping With Multiple SC Instances in a Wide-Area Network

Publication Year: 2018, Page(s):529 - 541
| | PDF (2703 KB) | HTML

Network function virtualization (NFV) aims to simplify service deployment using virtual network functions (VNFs). Service deployment involves the placement of VNFs and in-sequence routing of traffic flows through VNFs comprising a service chain (SC). The joint VNF placement and traffic routing is called SC mapping. In a wide-area network (WAN), where several traffic flows, generated by many distri... View full abstract»

Existing distributed denial-of-service attack detection in software defined networks (SDNs) typically perform detection in a single domain. In reality, abnormal traffic usually affects multiple network domains. Thus, a cross-domain attack detection has been proposed to improve detection performance. However, when participating in detection, the domain of each SDN needs to provide a large amount of... View full abstract»
