    Challenges on the performance prediction of softwarized network functions on shared resources become disruptive to reaping the benefits of network function virtualization (NFV). This paper addresses this problem and reveals a key technique to achieve its high accuracy. Our 2 prediction algorithms (ie, DCC-u and sDCC) based on dilated CPU consumption model can precisely predict the maximum throughput of the packet forwarding function corresponding to its assigned resources on NFV infrastructure.

  2. CATENAE: A scalable service function chaining system for legacy mobile networks

    This article presents CATENAE, an efficient Service Function Chaining system for mobile networks. CATENAE builds chains of unmodified network functions without using any tunneling protocol and without requiring network modifications. It is ready to be deployed in mobile networks, integrates seamlessly with legacy network management systems and introduces no overhead in the (virtual) network functions.

  3. A novel blind traffic analysis technique for detection of WhatsApp VoIP calls

    In this work we have characterized WhatsApp voice calls through blind traffic detection, which allows to differentiate calls from other applications, such as sharing video, photo or messaging. Traditional techniques for detection of VoIP calls cannot be applied to the WhatsApp case because the traffic is obfuscated. Actually, our proposal only takes into account the WhatsApp traffic stream statistical features, and not the packet content.

  4. A hash-based distributed mapping control scheme in mobile locator-identifier separation protocol networks

    In the locator-identifier separation protocol (LISP), the existing mapping control scheme is based on a centralized approach, in which a map server is used as a mobility anchor for mobile hosts. However, such a centralized scheme has some limitations that include traffic overhead at the central map server, service degradation by a single point of failure, and large data transmission delay. In this article, we propose a new hash-based distributed mapping control scheme of end point identifier (EID) and local locator in the LISP-based mobile networks. In the proposed scheme, each access router in the mobile network has a distributed local map server. For a mobile host, a distributed local map server is designated to manage the associated EID local locator mapping by using a hash function. For roaming support, each gateway has a distributed global map server, which maintains visiting EID locator register.

  5. Specification, composition, and placement of network services with flexible structures

    We define the structure of network services in a flexible way that enables changing the order of network functions in case the functionality of the service is not influenced by this. Flexible structures allow the network orchestration system to choose the optimal composition of network functions. We present a heuristic algorithm for selecting among possible compositions of different services and a placement algorithm for such compositions. Using these solutions, we show that allowing flexibility in the service structure is feasible.
