In this paper we introduce a new approach to support QoS on wireless networks. It uses a new solution for QoS support on IPv6 networks named IntServ6 and introduce some extensions to bring resource reservations mobility. Our solution works over hierarchical mobile IPv6 networks. IntServ6 takes advantage of the IPv6 header flow label field to improve the router performance. It also improves the current standard solution for the resource reservation within tunnels for integrated services networks. Evaluation results show that this approach has a better router performance respect to the traditional integrated services solutions for mobile networks

One of the most critical situations in all world in 2020 year is the Covid-19 pandemic. All areas of society have colapsed due to the quarantine declared in several countries. One of the most important infrastructure resources in this situation is the Internet service because people have to work and study from home and such people connections have performed by Internet. Thus, Internet Service Providers had to endure increased traffic. In this paper, an analysis of Internet traffic over ISPs at Colombia was performed to understand what happened over such networks. Also, an estimate was made of the increase in network resources by means of a Closed Queued Network model. Results shows that Internet traffic increased for almost all operators with a percentage mean of 29.76 in March and 51.54 in April, and besides, network resources increased in a percentage near to 28.3 in March and 32.71 in April.

This paper proposes an approach to supportEnd-to-End Quality of Service over IPv6 networks. In our solution, IPv6 flow labels are used to give better performance into the process of packet classification on network routers. In order to evaluate our proposal, a router model is obtained and it is compared with other technologies as IntServ and MPLS. As result, we obtain a solution with benefits of QoS support and label switching in IPv6 routers.

One of the radical changes that have occurred in current IP networks has been the migration from IPv4 to IPv6. One of the most important aspects of the IPv6 protocol is the fact that allows the labeling of packets belonging to a particular flow in order to give proper treatment by routers, for such purpose, the "Flow Label" field was originally created. However, this field has not been exploited yet and it has even been shelved due to the rise of other technologies such as MPLS. With the rise of IPv6 world implementation, it is essential to know the requirements of the use of this field to exploit the functions for which it was created. This article describes the IPv6 flow label field evolution, specifications and recommendations published by the IETF to use it; also here, some approaches are described, which have been proposed so far using the Label Flow for different purposes.
