I2C Bus

Read carefully the subject before answering. The document given in here describes the I2C bus. Question1 (1point) Is this standard issued from an official standardization agency (ISO,ITU,…) or from the scientific/industrial community (IEEE,IETF,…)? Question2 (1point) How many wires are necessary to transport data? What is the purpose of the clock signal? Question3 (1point) With a … Read moreI2C Bus

6PE

The goal of this exercise is to study 6PE (IPv6 Provider Edge) transition mechanism described in draft-ooms-v6ops-bgp-tunnel-00.txt (now published as RFC 4798, since the draft is very old, the solution proposed here are not exactly what have been standardized). This principle is implemented by many major router manufacturers. This proposal combines one IGP, MPLS and BGP to allow an ISP to carry efficiently IPv6 traffic without modifying core routers. Only edge routers have to be modified to understand IPv6 protocol. In the rest of this exercise we will study progressively the Internet Draft and the different elements of this proposal.

RES1 Data Link Layer (9/12)

Data Link Layer The exercises shown that Send and Wait protocol does not offer good performances when propagation delay is long compared to transmission time. In that case it is better to send several unacknowledged frames instead of waiting for acknowledgments before sending another frame. We study HDLC protocol which can be view as the ancestor of … Read moreRES1 Data Link Layer (9/12)
