  1. 1. Realizing High Performance NFV Service Chains

    Författare :Georgios P. Katsikas; Dejan Kostic; Gerald Maguire Jr.; Fabian Schneider; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; service chains; profiler; scheduling; multiplexing; synthesis; line-rate; 40 Gbps; NFV; service kedjor; profilering; planläggningsstrategier; syntetiserade; 40 Gbps; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

    Sammanfattning : Network functions (NFs) hold a key role in networks, offering in-network services, such as enhanced performance, policy enforcement, and security. Traditionally, NFs have been implemented in specialized, thus expensive hardware. LÄS MER

  2. 2. Towards SDN/NFV-based Mobile Packet Core : Benefits, Challenges, and Potential Solutions

    Författare :Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Kurt Tutschku; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mobile packet core; evolved packet core; SDN; NFV; 5G; scalability; load balancing; control plane; open5Gcore; Computer Science; Datavetenskap;

    Sammanfattning : In mobile networks, the mobile core plays a crucial role in providing connectivity between mobile user devices and external packet data networks such as the Internet. Through the years, along with the dramatical changes in radio access networks, the mobile core has also been evolved from being a circuit-based analog telephony system in its first generation (1G) to become a purely packet-based network called the Evolved Packet Core (EPC) in the current generation (4G).

  3. 3. NFV Service Chains at the Speed of the Underlying Commodity Hardware

    Författare :Georgios P. Katsikas; Dejan Kostic; Gerald Q. Maguire Jr.; Rebecca Steinert; Fabian Schneider; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; service chains; synthesis; offloading; tagging; zero inter-core communication; line-rate; 100GbE; NFV; tjänstekedjor; syntetisering; processavlastning; paketmärkning; ingen inter-CPU-kommunikation; länkkapacitet; 100GbE; Datalogi; Computer Science; Informations- och kommunikationsteknik; Information and Communication Technology; Telecommunication; Telekommunikation;

    Sammanfattning : Link speeds in networks will in the near-future reach and exceed 100 Gbps. While available specialized hardware can accommodate these speeds, modern networks have adopted a new networking paradigm, also known as Network Functions Virtualization (NFV), that replaces expensive specialized hardware with open-source software running on commodity hardware.
