IEEE Transactions on Network and Service Management

Maximal automation of routine IT maintenance procedures is an ultimate goal of IT service management. System monitoring, an effective and reliable means for IT problem detection, generates monitoring ticket. In light of the ticket description, the ...

Network virtualization has evolved as a key enabling technology for offering the next generation network services. Recently, it is being rolled out in data center networks as a means to provide bandwidth guarantees to cloud applications. With increasing ...

In a virtual network environment, a substrate network provider allocates computing and networking resources for service providers who request virtual networks to be created for particular services, and it also has the capability to provide resilient ...

Many critical e-commerce and financial services are deployed on geo-distributed data centers for scalability and availability. Recent market surveys show that failure of a data center is inevitable resulting in a huge financial loss. Fault-tolerance in ...

Software-defined networking (SDN) is a softwarization technology of networks that can optimize processes and operation costs and bring new values to infrastructures. The issue of reliability, however, becomes more complex in SDN due to new and multi-...

Network function virtualization (NFV) and software defined networking (SDN) have been proposed to increase the cost-efficiency, flexibility, and innovation in network service provisioning. This is achieved by leveraging IT virtualization techniques and ...

Quality of service (QoS) has been playing an increasingly important role in today’s Web service environment. Many techniques have been proposed to recommend personalized Web services to customers. However, existing methods only utilize the QoS ...

With the introduction of network function virtualization technology, migrating entire enterprise data centers into the cloud has become a possibility. However, for a cloud service provider (CSP) to offer such services, several research problems still need ...

In cloud data centers (DCs), where hosted applications share the underlying network resources, network bandwidth guarantees have shown to improve predictability of application performance and cost. However, recent empirical studies have also shown that ...

This paper studies the feasibility of minimizing convergence delay and forwarding disruption without carrying any additional bits in the IP header, to provide high availability despite link failures in traditional IP networks. Previously proposed ...

Cloud storage systems are emerging as the primary solution for online storage and information sharing. As the demand for such a service is increasing at a phenomenal rate, the cost for maintaining and delivering content concerns the cloud providers and ...

With over 300 billion vehicle trips made in the United States and 64 billion in France per year, network operators have the opportunity to utilize the existing road and highway network as an alternative data network to offload large amounts of delay-...

Article synchronization is one of the most fundamental issues in online social networking services (SNSs). In particular, when deploying multiple access networks with different transmission costs, an efficient synchronization scheme should be devised for ...

As the demand for higher data rates is growing exponentially, homogeneous cellular networks have been facing limitations when handling data traffic. These limitations are related to the available spectrum and the capacity of the network. Heterogeneous ...

This paper addresses the problem of access point (AP) selection in large Wi-Fi networks. Unlike current solutions that rely on received signal strength to determine the best AP that could serve a wireless user’s request, we propose a novel ...

Interest in underwater acoustic sensor networks (UW-ASNs) has rapidly increased with the desire to control the large portion of the world covered by oceans. Fundamental differences between underwater acoustic propagation and terrestrial radio propagation ...

The Internet of Things is characterized by the large-scale deployment of low power and lossy networks (LLN), interconnecting pervasive objects. The routing protocol for LLN (RPL) protocol has been standardized by IETF to enable a lightweight and robust ...

Software defined networking (SDN) is a novel networking paradigm which decouples control plane from data plane. This separation facilitates a high level of programmability and manageability. On the other hand, it makes the SDN controller a bottleneck and ...
