Packet Optical Transport Network is the solution for the fast growing packet traffic being carried on the traditional TDM-based SONET/SDH network. It merges packet routing/switching, wavelength switching, and connection-oriented Ethernet functionalities onto a single device. It allows the convergence of the Layer 1, 2 and 3 networks in order to reduce network costs, and provide more flexible services across the carrier networks. This panel will discuss the driver and benefits of the P-OTP as well as the challenges of the technology from router equipment vendor, transport equipment vendor, and service provider’s perspective.

Tutorials
The path towards profitable operation of networks today is paved with emerging premium services with strict requirements to bandwidth, delay, packet loss and resilience. Examples are IPTV, Video on Demand (VoD), Videoconferencing and telemedicine. They all use IP on the packet layer, but they demand reliable underlying transport networks for proper Quality of Experience (QoE). In a telemedicine video streaming application, where a doctor with special expertise remotely acts as second opinion, multi layer resilience is obviously required. In addition, such a service has strict delay bounds, which demands fast recovery or protection switching. Other services like IPTV require multicast transport, and the ability to quickly identify and isolate a faulty situation in a complex multicast architecture can make the difference between profitable or non-profitable operation. The demand for high quality reliable services further increases the complexity when the range of the services extends the local network and multi-domain issues arise. Hence, standardized connection monitoring is required to proactively avoid most errors and to react swiftly to the remaining. Therefore Telecom carriers have spent more than 10 years developing a Next Generation Network concept that will allow them to replace the classical transport network to provide high quality packet transfer. Carrier Ethernet technologies address these challenges by adding transport functionalities including resilience to an MPLS like network architecture.

This tutorial provides a thorough introduction to the Carrier Ethernet technology. In particular, we focus on MPLS-TP and PBB-TE and related Operation, Administration and Maintenance (OAM) functions. Furthermore, we address how Carrier Ethernet technologies can be used in the transport network to provide resilience to the packet layer. Explicit focus is on the multicast situation, where the signalling to identify faults is described. The standards covering the field are presented, and ongoing efforts in different standardization bodies are detailed. Finally, we present illustrative examples and best practises of how Carrier Ethernet can be applied for resilient IPTV transport.

Accompanied with rapidly growing real-time traffic in the Internet, the policy-based routing which can provide variable levels of quality of services becomes more important. For Internet routers to provide different service qualities for each flow, packet classification is an essential prerequisite. Packet classification classifies an incoming packet based on predefined rules so that the packet can be provided with the service defined for the class to which it belongs. In this tutorial, efficient algorithmic approaches for packet classification are comparatively studied. Packet classification algorithms can be classified into different categories depending on their principles: algorithms based on hierarchical approach, algorithms based on range cutting, and algorithms based on individual field search. Using a consistent set of example data, a set of different algorithms is explained in each category with respects to their data structures, characteristics, and performances. Performance of each algorithm is evaluated using pre-defined metrics such as search speed, memory requirement, and table update. Simulation results will be shown for the well known rule database with the sizes of 1000 and 5000 rules created from Classbench. Suggestions are made for the choice of algorithms depending on the number of rules, rule statistics, or implementation flexibility, etc.
