Data networks have become increasingly complex nowadays. Even though technologies like Ethernet, IP protocol and packet forwarding is rather simple, control mechanisms like middleboxes, Access Control Lists (ACLs), firewalls, traffic engineering, VLANs, etc. have largely contributed to increasing their complexity. Primarily this is due to the lack of basic principles in networking. Networking s...

Wu), michel The Resource Reservation Protocol for Traffic Engineering (RSVP-TE) must recover its state after a control plane failure so that the established connections in the data plane continue to be provided full services, ...

Over the last years, Distributed Denial-of-Service (DDoS) attacks have become an increasing threat on the Internet, with recent attacks reaching traffic volumes of up to 500 Gbps. To make matters worse, web-based facilities that offer “DDoS-as-a-service” (i.e., Booters) allow for the layman to launch attacks in the order of tens of Gbps in exchange for only a few euros. A recent development in ...

Software Defined Networking (SDN) is an important approach to network design which uses software to enable networked systems to expand data flow control. Data centre is a facility used to house computer systems and associated components, such as telecommunication equipments, storage systems and backup systems. Networks are a critical component of data centres for getting efficient outputs / res...

This document specifies a method to split the control plane (CP) and user plane (UP) for a network infrastructure based on Proxy Mobile IPv6 (PMIPv6). Existing specifications allow a mobile access gateway (MAG) to separate its control and user plane using the Alternate Care-of Address mobility option for IPv6 or Alternate IPv4 Care-of Address option for IPv4. However, the current specification ...

Although software-defined networking (SDN) brings numerous benefits by decoupling the control plane from the data plane, there is a contradictory relationship between SDN and distributed denial-of-service (DDoS) attacks. On one hand, the capabilities of SDN make it easy to detect and to react to DDoS attacks. On the other hand, the separation of the control plane from the data plane of SDN intr...

Home base stations (HBSs), which are considered to be useful extensions to mobile operators’ networks, are a promising solution for many issues in mobile communication networks, such as coverage, capacity, and cost. They deliver a great user experience for services in the home or in office buildings using customers’ broadband access for backhaul. However, connecting to the mobile operators’ net...

This paper compared the auto-discovery functionality between GMPLS and ASON, and found the current LMP in GMPLS needs to be modified to meet with the requirements of the ITU-T standard. To efficiently communicate the auto-discovered information between the control plane and the management plane, we proposed the interface between the two planes should be standardized.

Object stores are becoming pervasive due to their scalability and simplicity. Their broad adoption, however, contrasts with their rigidity for handling heterogeneous workloads and applications with evolving requirements, which prevents the adaptation of the system to such varied needs. In this work, we present Crystal, the first Software-Defined Storage (SDS) architecture whose core objective i...

This paper presents PADS, a policy architecture for building distributed storage systems. A policy architecture has two aspects. First, a common set of mechanisms that allow new systems to be implemented simply by defining new policies. Second, a structure for how policies, themselves, should be specified. In the case of distributed storage systems, PADS defines a data plane that provides a fix...
