Multipath communication is an attractive solution to the increasing need for improving web performance, by allowing devices aggregate capacity of different network paths, which can thus lead lower latencies. However, path asymmetry known incur performance issues multipath transport protocols, such as head-of-line blocking (HoLB), well other issues. We propose a proof-of-concept algorithm stream-aware packet scheduler QUIC, called Stream-Aware Earliest Completion First (SA-ECF). SA-ECF...
Bundling of multiple access technologies is currently being standardized by 3GPP in the 5G traffic steering, switching and splitting (ATSSS) framework, with goal to increase robustness, resiliency capacity wireless access. A key part an ATSSS framework packet scheduler, which decides network over each be transmitted. As channels are highly dynamic, a challenge for any scheduler correctly estimate path, thereby avoid congesting paths. In this paper, we further develop recent that exploits...
Cooperative intelligent transport systems (C-ITS) enable information to be shared wirelessly between vehicles and infrastructure in order improve safety efficiency. Delivering C-ITS services using existing cellular networks offers both financial technological advantages, not least since these already offer many of the features needed by C-ITS, on our roads are connected networks. Still, pose stringent requirements terms availability latency underlying communication system; that will hard...
Bundling multiple access technologies increases capacity, resiliency and robustness of network connections. Multi-access is currently being standardized in the ATSSS framework 3GPP, supporting different bundling strategies. Within ATSSS, a multipath scheduler needs to decide which path use for each user packet based on characteristics. The Cheapest Path First (CPF) aims utilize cheapest (e.g. WiFi) before sending packets over other paths cellular). In this paper, we demonstrate that using...
5G mobile networks introduce the concept of network slicing, functionality creating virtual on top shared physical infrastructure. Such slices can be tailored to various vertical services. A single User Equipment (UE) may served by multiple slice instances simultaneously, which opens up possibility dynamically steering traffic in response specific needs individual applications – and as a reaction events inside network, e.g., failures.This paper presents PoLicy-based Architecture for Network...
The network slicing concept of 5G aims to provide the flexibility and scalability required support a wide array vertical services. To coordinate coexistence slices, guarantee that resources are available for each one them, core employs management entity, slice manager. In this paper, we propose an architecture where is extended beyond access networks also include configuration UE's stack. We exploit manager's global view on feed fine-grained information configuration, health, status UE. This...
