“…Bandwidth and QoS offered by the current service are no longer sufficient. In [3], the challenges faced by service providers in moving from legacy SDHbased to MPLS-TP networks were reviewed, and the results indicated that the integration of optical and packet-based networks indeed offers simplicity, flexibility and scalability and improved results in backhaul networks. The use of MPLS-TP as the metro access network offered rapid end-to-end service provisioning.…”

“…Given the considerable benefits of MPLS networks, research is being conducted to ensure that high-bandwidth demand can be addressed. Several related reviews on MPLS networks [3][4][5][6][7], with their advantages, are summarised in Table 1. However, these studies have focused on only one MPLS technology, whereas our review paper addresses broad-ranging MPLS technologies, including traffic engineering (TE), differentiated services (DiffServ), protection and restoration, and MPLS-transport profile (MPLS-TP, an MPLS protocol), in addition to its applications and recent issues.…”

“…However, the ability to service these networks has not kept pace with the growth of Internet demand [ 11 ]. This hindered the recovery of investments made, especially as these networks approached their physical limitations [ 9 ] and were left without margin to generate new revenues and higher operating costs [ 10 ]. This was because the technologies of these networks were not fully flexible [ 8 ].…”

“…First, because Internet demand is growing driven by increasing customer numbers [2], by the emergence of new technologies [3][4][5], and by applications of the Internet of Things (IoT) and Smart Cities (SC) systems [6]. Second, because Internet networks are unable to serve new customers due to technological limitations [7,8], approach their physical limitations [9,10]. More than two distinct challenges, the opposite direction between declining network capacity and growing Internet demand [11] signals that the scenario ahead calls for an urgent solution: expanding (current or new) Internet networks.…”

Expand or Oversize? Planning Internet Access Network in a Demand Growth Scenario

Internet network design specialists are looking for technologies and strategies to deliver network service under increased demand conditions. The choice of strategies is based on applying optimization and decision-making methods to select the most appropriate cable network design considering criteria established by the problem definition. However, this definition is itself a decision problem that has not received analysis in the literature. In particular, one of the most important questions is the necessity to define an expansion strategy. The first alternative (expansion) is to design a network to serve consumers with Internet demand equal to or greater than the predefined one to expand the network annually to serve consumers that reach the predefined Internet speed. The second alternative (oversizing) is to design a network to serve consumers with future Internet demand (after 5 years) at or above that the predefined one. Considering this, the objective of this research is to define the most advantageous strategy of expansion planning to attend a 5 years forecasted Internet demand, considering: (1) the possibility of utilizing a Gigabit-capable Passive Optical Network technology; (2) the application of the minimal Steiner tree and Dijkstra algorithms in planning procedures; (3) the influence of economic and technological factors on the demand forecast; (4) the aggressive, moderate, and conservative scenarios in decision-making. The results show that the over-dimensioning strategy reduces network investment by between 30 and 41%, but that this reduction does not always lead to a market investment ratio higher than that observed in the expansion strategy.

“…The characteristics of MPLS-TP network can be illustrated in Figure 2. MPLS-TP can be implemented for the applications located at the edge or core network; metro or aggregation network; and also at the access network [7]. The environment of core network has high density of data traffic with limited number of sites, whereas; at the aggregation network, the traffic flow is much simpler but also critical at the same time, with high number of sites over medium size bandwidth.…”

In the perspective of Multiprotocol Label Switching – Transport Profile (MPLS-TP) network, a reliable framework architecture or mechanism needs to be ascertained by comparing the results obtained through implementation of previously proposed scheme towards the network. This is important in order to implement an efficient system for different types of applications or services. Various results are reviewed and analyzed from the related works followed by detail discussions based on their proposed objectives. The analyses shown that most applications of MPLS-TP have been utilized for protection, followed by Operations, Administration and Maintenance (OAM), fairness and congestion control. This is due to the mission-critical operational service of protection which require us to meet the standard protection switching time of 50 ms.
