“…BoD services are not widely deployed for several reasons, such as the lack of automation capabilities and the lack of a standard interface [1]. NG-SDH features such as VCAT(Virtual Concatenation) and LCAS (Link Capacity Adjustment Scheme) allows an operatorto provide BoD service across several multi-vendor transport networks [9] [10].…”

SDN is wildly studied as it enables new services and enhances existing services for telecom operators. Operators with large-scale optical transport networks might tend to operate newly-built SDN networks and legacy transport networks in parallel and gradually retire legacy devices. This study proposes a mediator approach to fulfill bandwidth adjustment demand with both SDN-ready and legacy devices. We applied the proposed approach to large-scale networks. The experiment result shows that this approach is feasible and brings higher hit ratio.

“…It has to meet the desired reliability for the M2M application, while supporting the high throughput demand of a wide variety of H2H multimedia services such as multimedia web browsing, video, online gaming. Various methods [2][3][4][5][6] for optimising bandwidth have been worked out for mobile and 802.1X networks like dynamic bandwidth allocation according to location/QoS. Some methods [7] adhere to the principle of fixed slot allocation for all cells which is not optimal in terms of bandwidth utilisation given the fact that different device types coexist in the network with different nature of bandwidth requirement.…”

A key factor for the evolution of the mobile networks towards 4G is to bring to fruition high bandwidth per mobile node. Eventually, due to the advent of a new class of applications, namely, Machine-to-Machine, we foresee new challenges where bandwidth per user is no more the primal driver. As an immediate impact of the high penetration of M2M devices, we envisage a surge in the signaling messages for mobility and location management. The cell size will shrivel due to high tele-density resulting in even more signaling messages related to handoff and location updates. The mobile network should be evolved to address various nuances of the mobile devices used by man and machines. The bigger question is as follows. Is the state-of-the-art mobile network designed optimally to cater both the Human-to-Human and Machine-to-Machine applications? This paper presents the primary challenges for the coexistence of M2M and H2H devices in a mobile network and draws emphasis for revisiting the mobility management aspects and congestion control in the-state-of-the-art network. Further, we set out a mobile network architecture with smart mobility management which aims to reduce the signaling interaction between the device and the network to optimise the power and bandwidth.
