At socket layer, the user can set the socket priority used by the networking stack to prioritise the packets. The kernel sends a high priority packet before a low priority packet but the exact behaviour depends on the traffic control layer. A priority based queueing discipline uses that value of priority to enqueue the packets while a multiqueue aware queueing discipline uses a priority mapping defined by the device to enqueue the packets in its queues. The enqueue event triggers a number of consecutive dequeues based on the implemented device flow control mechanism. In case of a WiFi device, an additional layer, named the Soft MAC layer, sits in between the networking API and the hard device MAC. This layer defines the priority mapping and the device driver uses the API provided by that layer to notify the kernel about the status of their queues. In this paper, we present the introduction of the socket priority and of the multiqueue networking infrastructure in ns-3 and the design of the new flow control infrastructure. Finally, we report a preliminary evaluation of our work, consisting of a number of tests that highlight the new behaviour introduced by our models.","PeriodicalId":309072,"journal":{"name":"Proceedings of the 2017 Workshop on ns-3","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130711580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the operators recognized it as the most important technology in LTE-A since it allows to quickly turn investment in additional LTE carriers into higher data rates. This is because CA allows a quick adoption and an efficient usage of fragmented and non-contiguous spectrum. Additionally, CA is a key technology for enabling some of LTE-A Pro technologies which are proposed in Release 13 and 14, such as, aggregation with unlicensed frequencies in the downlink, known as licensed assisted access (LAA), and LAA with aggregation in the uplink, known as enhanced LAA (eLAA). In this paper we describe the CA extension of the LTE module of ns-3 network simulator that we have implemented and contributed to ns-3 community. Firstly, we describe the motivation and technology background. Then, we describe the extension from a technical perspective, highlighting the new application interface being introduced, and the modifications of prior ns-3 LTE model involving the control and data planes of both the user equipment (UE) and evolved node B (eNB) protocol stack. Finally, we provide description of example scenarios and the validation of the carrier aggregation feature providing a performance comparison of the LTE system with and without CA capability.","PeriodicalId":309072,"journal":{"name":"Proceedings of the 2017 Workshop on ns-3","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132589932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wolisz","doi":"10.1145/3067665.3067675","DOIUrl":"https://doi.org/10.1145/3067665.3067675","url":null,"abstract":"The popularity of Internet-based video services has significantly increased over the past years. The de facto standard technology for Internet-based Video on Demand is HTTP-Based Adaptive Streaming (HAS), which is also increasingly used for live services. A core component of a HAS client is the adaptation algorithm, which dynamically adjusts the video representation to the network conditions. Meanwhile, there exists a large body of work on adaptation algorithms. Unfortunately, many experimental studies lack a thorough performance evaluation. Often, the reason is the use of an unrealistic network environment, or incomparability of results with other studies, or a too narrow subset of evaluated parameter configurations. We argue that a simulative approach can help resolving these issues by requiring less efforts to set up a realistic network environment, by assisting to reproduce an experiment, and by allowing to parallelize simulations, and potentially run them faster than in real time. The contribution of the present work is a design and implementation of a simulation model for a HAS-based application, including both the client and a server side. It has a clean modularized structure allowing for an easy integration of different adaptation algorithms. The client behavior is defined by a Finite-State Machine that can easily be extended to include additional functionality. Moreover, the model provides extensive logging functionality for monitoring the Quality of Experience (QoE). We integrate three state-of-the-art algorithms into the model: FESTIVE, PANDA, and TOBASCO2. We demonstrate the usefulness of the model by running a set of experiments using a simulated indoor Wi-Fi environment.","PeriodicalId":309072,"journal":{"name":"Proceedings of the 2017 Workshop on ns-3","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129507100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
