“…If the flow exists, the allocated bandwidth is assigned according to the adjusted rate of available resources for the slice flow. However, if the flow is new or flow entry expires, then a packet in message is send to the controller [19,20,21]. Controller defined rules according to our policy framework for fair allocation.…”

In cellular networks, physical resources are always limited, especially when shared among different contributors such as mobile network operator (MNO) or mobile virtual network operators (MVNO) etc. Software Defined Network (SDN) and Network Function Virtualization (NFV) is a Current research area. SDN-based cellular networks provide high Quality of Services (QoS) to the end-user and NFV provides isolation. The sharing of resources is often provided by leveraging virtualization. SDN can generate new forwarding rules and policies for dynamic routing decision based on the traffic classification. However, virtualization in cellular networks is still in infancy and many issues and challenges remain unaddressed. The queue-length problem for providing QoS is cellular network requires attention. The queue management requires separate management protocols for fair allocation of resources. In this research paper, we propose a novel framework for resource allocation and bandwidth management in the 5G cellular network. We are using two level of virtualization, i.e., implementing dynamic resource optimization at network slice manager and executing optimized policies at the wireless virtual manager.

“…In , the firm executes the sell option if and only if the additional revenues (discounted cashinflows) from selling the use of the web service are higher than the additional costs (discounted cash- 2 The internal use of a web service usually causes a similar amount of revenues regardless of whether a firm develops or obtains it (due to equal functionalities). Consequently, revenues have no (decision-relevant) effect on the make-or-buy decision, which is why revenues from the internal use remain unconsidered in traditional make-or-buy approaches (cf., [20,87]).…”

“…Service-oriented architectures have become the dominant design principle for application systems and enterprise architectures (e.g., [2,22,41,81,89]). This is due to the fact that web services (cf., [84] for their characteristics) promise to enable a flexible and cost-efficient execution of business processes because of their structure, communication, and interfaces that follow well-defined, general standards [82].…”

Abstract:The emergence of the web service market has enabled firms to choose between developing web services internally and purchasing them externally from web service providers. In general, these socalled make-or-buy decisions have been the object of intense debate in the IT outsourcing literature.However, characteristics of web services such as loose coupling and the current trend of digitalizing application interfaces enable new opportunities especially to non-software firms: when a firm decides to develop a web service internally (make-decision) it has the option of exposing and selling the use of this web service after its internal development (sell option). In this paper, we propose a normative approach for the valuation of such a sell option based on real option theory, taking into account the characteristics of web services. This approach enhances traditional make-or-buy approaches by additionally considering this sell option in decision-making. Our results are twofold: (I) the sell option has considerable impact on traditional make-or-buy decisions and makes the internal development of web services more attractive; (II) it is preferable to execute the sell option as soon as possible after completion of the internal development of the web service.

Task management is of a paramount importance because of the daily execution of more or less urgent and important tasks. In this paper, we propose a policy to indicate the necessary tasks and calculate their ranking, using a compromise between the available resources and the quality of service (QoS) granularity in the same task type. We applied a guaranteed technique in order to achieve an intelligent loss of tasks according to the importance of each task. A dynamicity of constraints was then used to attain an increase of availability, performance, reliability and system dependability. The results obtained from the proposed policy reveal that this type of policy can be extremely valuable for companies that wish to focus their efforts and resources to guarantee a satisfactory QoS for their clients.
