  4. 3. Performance, Isolation and Service Guarantees in Virtualized Network Functions

    Författare :Muhammad Siraj Rathore; Peter Sjödin; Markus Hidell; Andrea Bianco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; virtual router; service guarantee; scheduling; rate control; Computer Science; Datalogi;

    Sammanfattning : A network is generally a collection of different hardware-based network devices carrying out various network functions, (NF). These NF implementations are special purpose and expensive. Network function virtualization (NFV) is an alternative which uses software-based implementation of NFs in inexpensive commodity servers.
