“…of 10.16 Pbit/s per fiber [1]. However, although there are amount of services and enough spectrum resource, owing to sequential optical connections set-up without consideration of the delay tolerance of services, many optical connections of services cannot be set up timely, which will cause a service level agreement violation and penalty due to that service requests cannot be handled within the delay tolerance [2]. Meantime, the emergence of a variety of delay sensitive services such as remote medical, financial data and cloud computing results to that the technologies of optical transmission and networking are developing toward timely end-end response and flexible and efficient solutions [3].…”

The fast and diversified development of Internet services leads to numerous services with differentiated delay tolerance of optical connections set-up are converging in the optical network. Consequently, the average set-up delay of optical connection is increased, which will inevitably bring pressures to optical networks. To solve this problem, a delay aware routing spectrum assignment (RSA) algorithm based on services scheduling in priority queues with dynamic virtual topology construction (QVT-RSA) is proposed. First, the QVT-RSA algorithm reasonably identifies various different services and arranges them in order according to their priority, waiting time and delay tolerance requirements. Then, software defined networks (SDN) controller with multi-threads technology is adopted to innovatively parallel serve the ordered service requests to reduce the average set-up delay of optical connections, which also offset the induced delay caused by services scheduling. The network resource is accurately shared among multi-threads using the proposed mutual exclusive resource utilization model realized by dynamic virtual topology construction. The continuously coloring and usable virtual topology linkage reconfiguration can provide topology resources for service requests and adapt the dynamic transformation among serving, waiting and new arriving service requests. The shortest-path routing and first fit spectrum assignment (SPFF-RSA) algorithm is used as the baseline algorithm. Furthermore, by combining the SPFF-RSA algorithm and partial strategy of our strategy, the QSPFF-RSA and V-RSA algorithms are proposed as baseline algorithms as described in V-B. The simulation experiment results demonstrate that the average optical connections set-up delay of QVT-RSA algorithm is reduced compared with SPFF-RSA and QSPFF-RSA algorithms, and the blocking probability of QVT-RSA algorithm is reduced compared with SPFF-RSA, QSPFF-RSA and VRSA algorithms. The optical connections set-up success probability within delay tolerance about high, medium and low priority services of QVT-RSA algorithm is higher than that of the SPFF-RSA, QSPFF-RSA and VRSA algorithms.INDEX TERMS Low delay, QoS, reconfiguration of virtual topology, RSA, services scheduling.

“…The term SP refers to corporations that supply data and communication services to their customers. SPs may manage networks by themselves, or they may integrate the other SPs services to deliver an entire service to their clients/customers [8] [13] -in this work referred as EUs. The SP can operate in different business forms such as an Internet Service Provider (ISP), a carrier, Application Service Provider (ASP) or an operator.…”

The question of how to specify, provide and measure service quality for network end-users has been of utmost interest for service and network infrastructure providers and their clients as well. The Service Level Agreement (SLA) is a beneficial tool in formalizing the interrelationships resulting from a negotiation among all participating actors with the target of achieving a common comprehension concerning delivery of services, its priorities, quality, responsibilities, and other relevant parameters. A horizontal SLA is an agreement between two service-providers existing at the same architectural layer (as for example two Internet Protocol (IP) or two Optical Transport Network (OTN) domains). A vertical SLA is an agreement between two individual providers at two different architectural layers (for instance, between an optical network and the core MPLS network). A service has to be defined without ambiguity utilizing Service Level Specifications (SLS) and three information types must be described: i) The QoX metrics as well as their corresponding thresholds; ii) A method of service performance measurement; iii) Service schedule. In this work we present preliminary simulation results that enable the development of a generic methodology for SLA modeling and establishment that will lead to a win-win situation for all involved actors. As an example, we put special attention in the benefits obtained by Optical Networks operators.

The article reveals the main features of network Internet technologies as a significant management tool for information and network economy. The author depicts the most promising areas of network Internet technologies application, provides examples of successful implementation of projects based on network technologies, and underlines the most significant social effects of management practices in the area. Building of knowledge in expert networks, and transformation of the very actor of management are among these effects. Based on the author's empirical research conducted in 2016 among 100 leaders and administrators of big Russian Internet-communities, the main managerial advantages and possibilities of applying network technologies have been revealed.
