[Einherjar]

We are pleased to invite you to our next Open Seminar organized by AIT on Monday, November the 29th, at 16:30. The Seminar that will take place in amphitheatre 3A (3rd Floor), is entitled “Flow-Based Networking'” and will be conducted by Dr. Christos Kolias, Assistant Professor at AIT.

You may register at cefs@ait.edu.gr until Monday noon, November the 29th.

Abstract

A new networking paradigm and trend has recently emerged where internet (IP-based) traffic is modeled and managed at a (micro) flow-level. Flow-aware communication has become increasingly important for the Internet as more applications demand specialized treatment and QoS guarantees. It can present key benefits both at the network and the node level and offer critical support for value-added premium IP services. Flow-based networks can immensely support and provide for applications such as IP telephony, P2P, VoIP, VoD, videoconferencing that require service differentiation. In addition, internet security can significantly benefit from the flow-based technology. Other attractions of flow-based networking include the improved provisioning and management of bandwidth, jitter and other critical network resources. Issues such as efficient load balancing, network utilization and scalability are better addressed. Flow-state routing can naturally resolve the QoS challenges in IP, avoiding however the signaling overhead and complexity introduced in ATM networks. Flow-based congestion control eliminates the intricacies inherent to IP-base schemes, hence improving the overall network goodput and end-user perception. The flexibility and capabilities of flow-based networking not only can facilitate the convergence of network technologies such as IP, ATM and Frame Relay but also lead to significant network consolidation thus presenting considerable cost savings and revenue generation for internet service providers and operators. This fresh traffic engineering approach and modality aspires to set a new standard in routing and processing internet packets. In building the next generation IP, perhaps IP QoS will not be an oxymoron any longer.
