Scalability Analysis of a Media Aware Network Element
An architecture based on new concepts of Content Aware Networking (CAN) and Network Aware Applications (NAA) is proposed in FP7 ALICANTE research project as a better support for multimedia flows across the internet. A virtual CAN is a multi-domain overlay network based on light virtualization, provisioned to enable customized treatment of data flows and especially media streams. While it uses legacy QoS technologies, such as core IP/MPLS/Diffserv in the core routers, it proposes a new edge router, called MANE (Media Aware Network Element), CAN capable. This paper presents a modular MANE implementation solution using off-the-shelf hardware and open source software like Click modular router to implement flow classification, MPLS encapsulation and de-capsulation, separation between VCANs, and QoS enforcement with Linux TC (Traffic Control) mechanism.
