The document discusses the seven layers of the OSI model:
1) The physical layer deals with physical connectivity including cables and connectors.
2) The data link layer handles MAC addressing and encapsulation of data into frames.
3) The network layer routes packets based on IP addressing and protocols like ICMP and ARP.
4) The transport layer handles reliable transmission of data through protocols like TCP and UDP.
5) The session, presentation, and application layers deal with establishing connections between applications and formatting data.
Mobility, traffic engineering and redundancy using RPLMaxime Denis
Master thesis presentation. Design and implementation of a solution to improve mobility between two physical WSNs using RPL. Based on the 6LBR implementation of the CETIC.
This video presents an educational overview of the RapidIO architecture and ecosystem. The RapidIO architecture is a high-performance packet-switched, interconnect technology for interconnecting chips on a circuit board, and circuit boards to each other using a backplane. This technology is designed specifically for embedded systems, primarily for the networking, communications, and signal processing markets.
Serial RapidIO solutions from IDT include switching and bridging products that are ideal for building peer-to-peer multi-processor systems with 100ns latency, low power consumption, reliable packet termination — all with industry-standard based support at up to 20 Gbps per port. IDT's Serial RapidIO solutions are ideal for wireless base station infrastructure, video, server, imaging, military and industrial control applications.

Shibata, N., Yasumoto, K., and Mori, M.: P2P Video Broadcast based on Per-Peer Transcoding and its Evaluation on PlanetLab, Proc. of 19th IASTED Int'l. Conf. on Parallel and Distributed Computing and Systems (PDCS2007), pp. 478-483, (November 2007).

We have previously proposed a P2P video broadcast method called MTcast for simultaneously delivering video to user peers with different quality requirements. In this paper, we design and implement a prototype system of MTcast and report the results of its performance evaluation in the real Internet environment. MTcast relies on each peer to transcode and forward video to other peers. We conducted experiments on 20 PlanetLab nodes, evaluated startup delay and recovery time from peer leaving/failure, and confirmed that MTcast achieves practical performance in a real environment.
