“…The high-priority and latency-sensitive classes require a 6ms end-to-end latency guarantee. Note that here, as explained above, we only deal with bandwidth and latency as the service requirements, but the framework can readily accommodate availability and protection [39].…”

In an SDN-based network, service requests can be accommodated according to network application requirements. We devise a framework where such requirements drive IP and optical network resource allocation, dynamic optimization, and instantiation through an SDN orchestrator. The framework aims to balance the often-conflicting goals such as energy savings and resource allocation speed, while ensuring that the orchestrator can accommodate incoming service requests without interrupting the running services. We show the functionality of the framework with a simulation on a real network topology and realistic input traffic. Index Terms-(060.4256) Networks, network optimization, (060.4251) Networks, assignment and routing algorithms I. INTRODUCTION pplications running over the Internet today, such as autonomous driving, remote surgery, 5G backhauling, and data migration, demand more than just a bandwidth pipe over a connected network. The new service requirements are specific and complex, so merely providing a sufficiently capacitated optical channel will not suffice. Moreover, bundling the traffic from diverse applications does have advantages of cost, but the resulting service may be inadequate, the usage of network resources may be inefficient, or the network operator may miss an opportunity to generate revenue from higher-class services. Recently, Software-Defined Networking (SDN) enables service providers to use the existing IP and optical network resources more intelligently and efficiently. This advance allows for assigning bandwidth where and when needed, and Manuscript received July 12 th , 2018.

“…A few works in the research literature addressed the problem of embedding in multi-layer networks [168,169,2]. In [168], the authors consider the problem of application-aware tra c embedding on IP/Multi-layer Protocol Switching(MPLS)-over-Optical Network. Tra c requests are given between pairs of routers in the network, where each request has di erentiated service requirements in terms of bandwidth, tolerable end-to-end delay, and tolerable end-to-end path availability.…”

“…Here, the possibility of establishing new IP links is also considered when the IP/MPLS layer does not have su cient capacity to meet the demand of a given request. However, in [168], the end points of the requests are xed and it only addresses the link routing problem. Moreover, [168] neither does propose an optimal solution to the problem, nor presents complexity analysis of the proposed heuristic.…”

“…The success of IP/MPLS in the access layer of multiservice broadband networks opened new horizons for building a unified network architecture using commonly used technologies. This allowed service providers to use the same technology throughout their network including at the access, aggregation and core levels, which results in [29,30]:…”

Broadband Communications Networks - Recent Advances and Lessons From Practice

With the rapid increase in users' demand for flexibility and scalability of communication services, broadband communication networks are facing an ongoing challenge of providing various broadband services using a single communication architecture. This leads to the evolution of a challenging field of multiservice broadband network architectures. This chapter discusses the basic concepts associated with broadband communication network architectures with emphasis on provision of multiservice, and it also focuses on the evolution of broadband communication networks from the traditional architecture to the incorporation of virtualization services, that is, cloud computing. Another important aspect, which relates to the multiservice broadband network, is the "applications" which, as this chapter highlights, are a key-driving factor for the evolution of broadband communication networks. Moreover, this chapter also includes a discussion on New Zealand's government initiatives to provide improved network coverage within the country.
