“…QoSoriented routing, provided by the HRM system, leads to an improved packet processing of competing multimedia streams through networks, which is not possible with today's networks. In contrast to approaches from literature [13], HRM operates on packets instead of flows. This avoids additional out-of-band end-to-end QoS signaling and prevents state information per flow on intermediate routers.…”

In this paper, we propose a new approach to enhance today's hop-by-hop routing. The main goal of our work is to improve the efficiency of network usage and to support transmission requirements (TR) provided by applications. In the paper, we focus on non-functional requirements such as a desired upper bound for the end-to-end delay and a required data rate. Both are encoded as meta data in each data packet. Furthermore, we describe how these embedded (in-band) TRs can be used for QoS-oriented routing, implemented on each intermediate router. This directs packets along routes, providing only the network resources actually needed. In order to support these routing decisions based on TRs, we utilize data from an additional control plane, which provides QoS-related topology data from the network. For this purpose, we apply our idea of "Hierarchical Routing Management" (HRM). It implements a signaling of QoSrelated route capabilities. In order to provide a scalable system, we apply hierarchical addressing and topology aggregation, resulting in fewer details in higher hierarchy levels. In detail, we describe how SCTP can be used to encode and transport the TRs for a multipath video-streaming scenario. Moreover, we explain the HRM internal signaling processes, which are required to create and use the HRM system. Compared to current IP routing, this allows for a better network efficiency and QoE at receiver side. Nevertheless, the HRM approach remains backward compatible to current application and router implementations. The paper shows that these benefits can be achieved at an acceptable overhead for packet processing.

“…Therefore, two-tier approaches use an end-to-end mechanism to establish QoS, which is independent of the mechanisms used to provide QoS in each network and on each link. A survey is given in [16]. However, the interface between both layers is not discussed.…”

Quality of Service (QoS) for inter-networks requires a two-tier approach to separate the end-to-end communication from the QoS provisioning within each autonomous system. However, the interaction between both is not standardized. Furthermore, the solutions for both tiers lack either scalability, flexibility, or QoS guarantees. Our paper presents a combination of "Forwarding on Gates" (FoG) as inter-network and "Traffic Engineering Middleware for Ethernet" (TEME) as intra-network techniques. This combination incorporating a recursive layer model separates the layers based on their scope and not on their functionality. This paper proposes a single interface used by all layers. Furthermore, the same interface is used by applications in order to signal their QoS requirements. This design allows supporting QoS in a more consistent way as compared to the ISO/OSI layer model. The paper outlines the proposal theoretically and demonstrates the advantages with an example.

“…These approaches have some major drawbacks. As it is working flow-based and stateful, scalability can easily become an issue [80], regardless of the presence of satellite links in the network or not. Hence, neither IntServ nor QoS-OSPF are widely deployed in larger networks.…”

It has been widely acknowledged that future networks need to provide significantly more capacity than nowadays' ones in order to deal with the increasing traffic demands of the users. Particularly in regions where optical fiber are unlikely to be deployed due to economical constraints, this is a huge challenge. One option to address this issue is to complement existing narrow-band terrestrial networks with additional satellite connections. Satellites cover huge areas and recent developments have considerably increased the available capacity, while the cost are decreasing. However, geostationary satellite links have significantly different link characteristics than most terrestrial links, mainly due to the higher signal propagation time, which often renders them not suitable for delay intolerant traffic. This article surveys the current state-of-the-art of satellite and terrestrial network convergence. We mainly focus on scenarios in which satellite networks complement existing terrestrial infrastructures, i.e. parallel satellite and terrestrial links exist, in order to provide high bandwidth connections while ideally achieving a similar end user Quality-of-Experience as in high bandwidth terrestrial networks. Thus, we identify the technical challenges associated with the convergence of satellite and terrestrial networks and analyze the related work. Based on this, we identify four key functional building blocks, which are essential to distribute traffic optimally between the terrestrial and the satellite networks. These are the Traffic Requirement Identification function, the Link Characteristics Identification function as well as the Traffic Engineering function and the Execution function. Afterwards, we survey current network architectures with respect to these key functional building blocks and perform a gap analysis, which shows that all analyzed network architectures require adaptations to effectively support converged satellite and terrestrial networks. Hence, we conclude by formulating several open research questions with respect to satellite and terrestrial network convergence.
