“…The proposed method is a simulation using SS-BGP (Self-Stable BGP) and ESS-BGP (Enhanced Self-Stable BGP) loop routing methods through a realistic internet topology by performing 100 different simulations to generate delay across links. According to [16] discuss about WMN (Wireless Mesh Networks) built by the US with hop-by-hop communication performance. The proposed method is a simulation of the hybrid loop-free routing approach and hybrid metric methods under lossy/not lossy area topology conditions.…”

This research began when observations were made on any-to-any-connection services that require QoS (Quality of Service) and tunnel measurements. Tunnel is a technique to interconnect between local networks that are separated through a public network. Research questions found looping caused by traffic issues when sending data in the MPLS service layer-2 tunneling service. Furthermore, this research hypothesis proposes optimizing QoS performance in the application of the SR-TE (Segment Routing-Traffic Engineering) method in the MPLS (Multi-Protocol Label Switching) network and analyzing traffic based on MAC addresses using the looping-protection method. This research contributes to optimizing the MPLS network and is a recommended solution for simplifying control-plane operation, especially the SR-TE method and looping-protection in the L2-VPN MPLS service. The purpose of this study is to analyze the performance of MPLS networks, as well as analyze the application of L2-VPN (Layer 2 Virtual Private Network) MPLS networks. The targeted TKT (Technology Readiness Level) is 3rd-Level, which is an analytical and experimental proof of the MPLS tunnel network model on Layer-2 VPN services. The results of the research concluded that testing the SR-TE method is a solution to simplify the process of labeling data traffic that is global labelling, then the looping-protection method is a solution to eliminate looping indications. The QoS obtained has also shown an "excellent" category based on TIPHON standards.

“…En [108], Takimoto et al identifican que la propuesta presentada en [97], denominada como PiggyCode, tiene beneficios para el desempeño de TCP al codificar paquetes de datos y paquetes de acuse que viajan en flujos bidireccionales; sin embargo, advierten que dichos beneficios dependen de la tasa de transmisión. Afirman que PiggyCode ofrece mayores beneficios cuando la red está cerca del punto de saturación; pero, si la tasa de transmisión es baja, la probabilidad de encontrar oportunidades de codificación en los nodos intermedios se reduce significativamente y de este modo se reducen también los beneficios de la codificación de red.…”

“…En [91,98,10,108] se demuestra que las oportunidades de codificación en un nodo se pueden incrementar si se incorpora un temporizador para los paquetes nativos en espera de una oportunidad de ser codificados. Si bien esta propuesta puede teóricamente mejorar los beneficios obtenidos por la técnica de codificación de red, ninguno de los autores señala las dificultades que se enfrentan para adaptar este temporizador a las condiciones de la red.…”

“…El objetivo principal de este análisis es identificar los efectos que tienen el mecanismo de acceso aleatorio al medio y la densidad de flujos TCP en la generación de oportunidades de codificación en los MAPs. Además, se propone configurar un esquema de codificación adaptativa que incorpore tiempos de espera para los paquetes nativos con el objetivo de formar una oportunidad de codificación -esquema inspirado en las propuestas [108,107,10]. A diferencia de las soluciones existentes en la literatura, en esta propuesta se plantea que el tiempo de espera de los paquetes nativos se ajuste de manera dinámica.…”

IEEE 802.11S INFRASTRUCTURE WIRELESS MESH NETWORKS (commonly known as iWMNs) are integrated by static wireless nodes capable of working in coordination to route data packets. In this way, the nodes collaborate to exchange information with each other. In addition, iWMNs can be interconnected with other network technologies and, in this way, help to wirelessly extend the coverage of these networks; for example, iWMNs are used today to extend the coverage of cellular or wired networks. Thanks to this feature, and also to their low infrastructure cost, iWMNs networks are considered today as an excellent option to offer wireless Internet connectivity services in geographical areas where the use of other network technologies is unfeasible. Despite the promising features of iWMNs, there are studies and results that cast doubt on their performance, since it has been documented that the performance of these networks can be affected by numerous factors; such as the use of TCP to transport information in wireless environments, the transmission errors in the wireless medium, as well as the access contention between network users. All these factors can degrade the performance of iWMNs and, consequently, affect the quality of the experience for the users. In this doctoral thesis, some of these performance problems are addressed through the technique called adaptive network coding. With this technique, the nodes of an iWMN are allowed to combine various data packets and thus build an encoded packet; this packet contains the information from the original packets, requiring only one wireless transmission to transport the original information, reducing the use of the wireless medium and, thereby, increasing the capacity of the network. The proposed technique also seeks to adapt the coding process to the traffic conditions in the network through the dynamic adjustment of the waiting time of the packets in a node before they can be combined. This proposal aims to substantially improve the performance of iWMNs, solving some problems that affect them. The evaluation of the proposal is carried out through simulations and numerical evaluations. After a detailed analysis of the results, we find that iWMNs can improve their performance by using the adaptive network coding technique, since the number of wireless transmissions in the network is considerably reduced, and, consequently, i) the medium access contention decreases, ii) the probability of errors in the medium is reduced, and iii) the capacity of the network increases.
