The communication network context in actual systems like 5G, cloud and IoT (Internet of Things), presents an ever-increasing number users, applications services that are highly distributed with distinct heterogeneous communications requirements. Resource allocation this requires dynamic, efficient customized solutions Bandwidth Allocation Models (BAMs) alternative to support new trend. This paper proposes the BAMSDN (Bandwidth Model through Software-Defined Networking) framework dynamically...
At the turn of 21st century, urban development has experienced a paradigm shift so that quest for smarter cities become priority agenda, with direct participation industry, policymakers, practitioners, and scientific community alike. The 2008 financial crisis, exodus from rural areas, densification centers coupled environmental sustainability concerns have posed enormous challenges to municipalities all over globe. United Nations predicts world population will reach 9.8 billion by 2050,...
DiffServ-aware MPLS-TE (DS-TE) allows bandwidth reservation for Traffic Classes (TCs) in MPLS-based engineered networks and, as such, improves the basic model. In DS-TE networks, per-Class quality of service guarantees are provided while being possible to achieve improved network utilization. requires use a Bandwidth Allocation Model (BAM) that establishes amount and any eventual sharing among them. This paper proposes new allocation model (AllocTC-Sharing) which higher priority traffic...
Bandwidth Allocation Models (BAMs) are used in order to define Constraints (BCs) a perclass basis for MPLS/DS-TE networks and effectively how network resources like bandwidth obtained shared by applications.The BAMs proposed (MAM -Maximum Model, RDM -Russian Dolls G-RDM -Generic AllocTC-Sharing) attempt optimize the use of on per-link with different allocation resource sharing characteristics.As such, adoption distinct and/or changes demands (network traffic profile) may result operational...
Bandwidth Allocation Models (BAMs) configure and handle resource allocation (bandwidth, LSPs, fiber, slots) in networks general (IP/MPLS/DS-TE, optical domain, other). In this paper, BAMs are considered for elastic slot targeting an improvement utilization. The paper focuses initially on proposing a BAM basic configuration parameter mapping suitable circuits. Following that, MAM, RDM ATCS applied the overall network utilization is evaluated. A set of simulation results behaviors presented as...
Bandwidth Allocation Models (BAMs) configure and handle resource allocation (bandwidth, LSPs, fiber) in networks general (IP/MPLS/DS-TE, optical domain, other). BAMs currently available for IP/MPLS/DS-TE (MAM, RDM, G-RDM AllocTC-Sharing) basically define restrictions (bandwidth) by class (traffic class, application user or other grouping criteria) allocate on demand this resource. There is a BAM policy inherent each existing model which behaves differently under distinct network state, such...
The Software Defined Networks (SDN) paradigm decouples control and data routing, offering high programmability a global view of the network. adoption this approach is growing in enterprise networks, centers critical infrastructure such as smart grids.
