It doesn't seem as if ICMPv6 Neighbor Solicitations are transmitted as a broadcast.

please please answer asap

Weirdly, ICMPv6 Neighbor Solicitations seem to be sent out as a multicast rather than a broadcast.

Needham and Schroeder suggest the following variant of their protocol: 1. Alice → Bob : Alice 2. Bob→ Alice: {Alice rand3}kBob 3. Alice → Cathy : {Alice Bob rand₁|{Alice rand3}kBob} 4. Cathy → Alice: {Alice Bob rand₁|ksession|{Alice rand3|ksession}KBob}KAlice 5. Alice → Bob: {Alice rand3|ksession}kBob 6. Bob→ Alice: {rand2}ksession 7. Alice → Bob: {rand2-1}ksession Show that this protocol solves the problem of replay as a result of stolen session keys. Hint: Consider two cases, one in which the attacker does not send an initial message to Bob and one in which the attacker does.

1. If the values of user tool frame UT[2] is (0, 0, 0, 0, 0, 0) in the robot system, then UT[2] (a) is not activated in the robot system (b) cannot be used in recording robot point P[n] (c) coincides with default TCP frame (Def-TCP) of the robot in the robot system (d) coincides with robot world frame R in the robot system 2. A frame transformation is given as 4T; = (X,Y,Z,W,P, R) = (0,0,0, –90, 0, 90). The corresponding graphical representation of the given frame transformation is (a) (b) y y

Write Algorithm for Auxiliary methods for the lockstep protocol.

The token bucket algorithm is a popular method for traffic shaping. A computer uses a token bucket with acapacity of 400 megabytes (MB) and a rate of 10 MB/sec. The computer continuously generates20 MB/sec for transmission from time 0. Assume the bucket’s water level is 200 MB at time 0.1a. How long will it take to send 1000 MB? Show the steps.1b. Draw a figure showing how the bucket’s water level evolves

ICMPv6 Neighbor Solicitations seem to be transmitted as a multicast rather than a broadcast, although this behavior makes no sense.
