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.

Abstract-Recently both academic and industry world has started to define the successor of Long Term Evolution (LTE), so-called 5G networks, which will most likely appear by the end of the decade. It is widely accepted that those 5G networks will have to deal with significantly more challenging requirements in terms of provided bandwidth, latency and supported services. This will lead to not only modifications in access and parts of core networks, but will trigger changes throughout the whole network, including the Back-haul segment. In this work we present our vision of a 5G Back-haul network and identify the associated challenges. We then describe our Wireless Back-haul (WiBACK) architecture, which implements Software Defined Network (SDN) concepts and further extends them into the wireless domain. Finally we present a brief overview of our pilot installations before we conclude.

“…If such a path exists, a corresponding pipe is set up by pushing LSP state into the involved WNs via the RSVP-TE-inspired Pipe Management Function (PMF), which also determines the end-to-end MTU and performs resource allocation on the transmitting interfaces along the path. This information may be used to program MAC schedulers, traffic shapers or may serve as thresholds for passive receiver-side link or LSP monitoring, as, for example, described in RFC 6374 [20], or in [21] for the WiBACK architecture.…”

Today's wireless operators must support the tripleplay service offerings demanded by the market or by regulatory bodies through so-called Universal Service Obligations (USOs). Typically, those services are offered within the scarce and precious wireless spectrum resources owned by the providers. In parallel, broadcasters provide live TV and radio programming via their own radio spectrum. The paradigm shift from live TV to time-shifted consumption blurs the previously clear separation between broadcasting services and multi-media content received via regular, wired or wireless, data networks. The expected reduction of live content through decomposition and clever rescheduling may result in temporarily vacated resources in the TV spectrum which could then be used for regular wireless data services. In this paper we argue that such a 'Dynamic Broadcast' scheme can be supported -at layer 2.5 -by our Wireless BackHaul (WiBACK) architecture, focusing on the architecture and protocol requirements to integrate Unidirectional Technologies (UDTs) such as DVB-T2 or ATSC. Initial validation results show that our WiBACK architecture can support a 'Dynamic Broadcast' system and provides the mechanisms to orchestrate such coordinated white space usage while providing a common MPLS-based transport.
