MobyDick FlowVis - using NeTraMet for distributed protocol analysis in a 4G network environment

Abstract

Abstrocl-The commercial operation of future "4G" mobile wireless nehvork comprising uniformly both IP-based voice and data is widely considered as the next challenge for service providers. Within such an IP-environment with its implicit integration ofthe control and data plane, passive measuring and metering will be one of the key elements for AAA and QoS provision, for performance and fault management purposes. Within the IETF, a real-time flow measurement framework has been developed for measurement and accounting for the fixed Internet infrastructure. This article, aner introducing briefly the IETF "Real-Time Flow Measurement" architecture, a pure IP 4C-architecture together with its key signalling scenarios. and JavslJZEE and Web middleware technology, describes "FlowVis" B high scalable and distributed IP based protocol visualization and verification framework for both signalling and data traffic. Combining the near-real-time capabilities of the existing IETF RTFM with current middleware technology, this framework, "FlowVis" can serve as a starling point for distributed protocol analysis in future 4G nehvorks.

Testbed for mobile network operator scenarios

“…The IST project Mobility and Differentiated Services in a Future IP Network (Moby Dick) [6] implemented an isolated testbed which integrated access technologies IEEE 802.11b and an UMTS-like access network are integrated. Vertical handovers are based on Mobile IPv6 and focus has been on Quality of Service (QoS) support in heterogeneous environments [7]. The isolated testbed does not integrate a real 3G operator environment.…”
