  text: The size of modern data centers is constantly increasing. As it is not economic
    to interconnect all machines in the data center using a full-bisection-bandwidth
    network, techniques have to be developed to increase the efficiency of data-center
    networks. The Software-Defined Network paradigm opened the door for centralized
    traffic engineering (TE) in such environments. Up to now, there were already a
    number of TE proposals for SDN-controlled data centers that all work very well.
    However, these techniques either use a high amount of flow table entries or a
    high flow installation rate that overwhelms available switching hardware, or they
    require custom or very expensive end-of-line equipment to be usable in practice.
    We present HybridTE, a TE technique that uses (uncertain) information about large
    flows. Using this extra information, our technique has very low hardware requirements
    while maintaining better performance than existing TE techniques. This enables
    us to build very low-cost, high performance data-center networks.

  text: 'Multi-rooted trees are becoming the norm for modern data-center networks.
    In these networks, scalable flow routing is challenging owing to vast number of
    flows. Current approaches either employ a central controller that can have scalability
    issues or a scalable decentralized algorithm only considering local information.
    In this paper we present a new decentralized approach to least-congested path
    routing in software-defined data center networks that has neither of these issues:
    By duplicating the initial (or SYN) packet of a flow and estimating the data rate
    of multiple flows in parallel, we exploit TCP’s habit to fill buffers to find
    the least congested path. We show that our algorithm significantly improves flow
    completion time without the need for a central controller or specialized hardware.'

abstract:
- lang: eng
  text: "The increasing amount of mobile traffic leads to a significantly higher energy
    consumption of mobile networks that is mainly caused by the high number of required
    base stations. One recent solution for this is based on a two-layered network
    that uses long-range macro cells to provide a full coverage signaling overlay
    and short-range small cells for fast data transmissions. These small cells can
    be switched off when they are not needed and allow network-wide energy optimizations.\r\n\r\nThis
    paper presents an architecture that extends existing mobile networks to integrate
    a small cell layer that supports on-demand cell activation. We discuss how additional
    small cells can be interconnected with existing core components and how they can
    be controlled by a resource management component. \r\nFinally, a Wi-Fi based proof
    of concept testbed implementation is presented that demonstrates the feasibility
    of the approach."

  text: Network emulations are widely used for testing novel network protocols and
    routing algorithms in realistic scenarios. Up to now, there is no emulation tool
    that is able to emulate large software-deﬁned data center networks that consist
    of several thousand nodes. Mininet is the most common tool to emulate Software-Deﬁned
    Networks of several hundred nodes. We extend Mininet to span an emulated network
    over several physical machines, making it possible to emulate networks of several
    thousand nodes on just a handful of physical machines. This enables us to emulate,
    e.g., large data center networks. To test this approach, we additionally introduce
    a trafﬁc generator for data center trafﬁc. Since there are no data center trafﬁc
    traces publicly available we use the results of two recent trafﬁc studies to create
    synthetic trafﬁc. We show the design and discuss some challenges we had in building
    our trafﬁc generator. As a showcase for our work we emulated a data center consisting
    of 3200 hosts on a cluster of only 12 physical machines. We show the resulting
    workloads and the trade-offs involved.

  text: 'Preemptive Routing and Wavelength Assignment (RWA) algorithms preempt established
    lightpaths in case notenough resources are available to set up a new lightpath
    in aWavelength Division Multiplexing (WDM) network. The selectionof lightpaths
    to be preempted relies on internal decisions of theRWA algorithm. Thus, if dedicated
    properties of the networktopology are required by the applications running on
    the network,these requirements have to be known to the RWA algorithm.We present
    a family of preemptive RWA algorithms for WDMnetworks. These algorithms have two
    distinguishing features: a)they can handle dynamic traffic by on-the-fly reconfiguration,and
    b) users can give feedback for reconfiguration decisions andthus influence the
    preemption decision of the RWA algorithm,leading to networks which adapt directly
    to application needs.This is different from traffic engineering where the network
    is(slowly) adapted to observed traffic patterns.Our algorithms handle various
    WDM network configurationsincluding networks consisting of heterogeneous WDM hardware.To
    this end, we are using the layered graph approach togetherwith a newly developed
    graph model that is used to determineconflicting lightpaths.'

  text: 'In distributed cloud computing, application deployment across multiple sites
    can improve quality of service. Recent research developed algorithms to find optimal
    locations for virtual machines. However, those algorithms assume to have either
    single-tier applications or a fixed number of virtual machines – a strong simplification
    of reality. This paper investigates the placement and scaling of complex application
    architectures. An application is dynamically scaled to fit both the current demand
    situation and the currently available infrastructure resources. We compare two
    approaches: The first one is based on virtual network embedding. The second approach
    is a novel method called Template Embedding. It is based on a hierarchical 1-allocation
    hub flow problem and combines applica- tion scaling and embedding in one step.
    Extensive experiments on 43200 network configurations showed that Template Embedding
    outperforms virtual network embedding in all cases in three metrics: success rate,
    solution quality, and runtime. This positive result shows that template embedding
    is a promising approach for distributed cloud resource allocation.'

  text: 'Network appliances perform different functions on network flows and constitute
    an important part of an operator’s network. Normally, a set of chained network
    functions process network flows. Following the trend of virtualization of networks,
    virtualization of the network functions has also become a topic of interest. We
    define a model for formalizing the chaining of network functions using a context-free
    language. We process deployment requests and construct virtual network function
    graphs that can be mapped to the network. We describe the mapping as a Mixed Integer
    Quadratically Constrained Program (MIQCP) for finding the placement of the network
    functions and chaining them together considering the limited network resources
    and requirements of the functions. We have performed a Pareto set analysis to
    investigate the possible trade-offs between different optimization objectives. '
