1.In distance vector algorithm, give me two conditions
that may cause the router to re-compute
the distance vector estimates?
2. What is called “hot potato routing”?
1. The router has to recalculate the distance vector in the
below situations:
a. When the information about the distance vector it has received from the neighbor is different than before. It has to recalculate the distance vector in this situation.
b. When it finds the link to its neighbor has gone
down/unresponsive. In this situation, it has to recalculate.
Hot Potato Routing is one of the types of routing mechanism in which the nodes of a network does not have any capacity or a buffer to store the packets before they reach its final predetermined destination. In this routing mechanism, each packet routed constantly until it reaches a final destination. It allows many packets to reach its final destination without dropping anywhere else.
Please do comment for any doubts or modifications!

Distance vector routing
In the illustrated network, routes are determined using the
distance vector algorithm . The marked router
v has been newly added, it only knows the direct
costs to its neighbor routers u ,
y and z .
(a) Specify the distance vectors in all routers
except v before adding v . We
assume that the distance vector algorithm for all routers existing
at this time is already terminated.
(b) Give the initial distance vector in the
router...
Q1 Error detection/correction Can these schemes correct bit errors: Internet checksums, two-dimendional parity, cyclic redundancy check (CRC) A. Yes, No, No B. No, Yes, Yes c. No, Yes, No D. No, No, Yes E. Ho, hum, ha Q2 CRC vs Internet checksums Which of these is not true? A. CRC's are commonly used at the link layer B. CRC's can detect any bit error of up to r bits with an r-bit EDC. c. CRC's are more resilient to bursty...
1.0. Suppose the network is as follows, where distance-vector
routing update is used. Each link has cost 1, and each router has
entries in its forwarding table only for its immediate neighbors
(so A’s table contains 〈B,B,1〉, 〈D,D,1〉 and B’s table contains
〈A,A,1〉, 〈C,C,1〉).
(a). Suppose each node creates a report from its initial
configuration and sends that to each of its neighbors. What will
each node’s forwarding table be after this set of exchanges? The
exchanges, in other words,...
(a) Suppose we want to solve the linear vector-matrix equation Ax b for the vector x. Show that the Gauss elimination algorithm may be written bAbm,B where m 1, This process produces a matrix equation of the form Ux = g , in which matrix U is an upper-triangular matrix. Show that the solution vector x may be obtained by a back-substitution algorithm, in the form Jekel (b) Iterative methods for solving Ax-b work by splitting matrix A into two...

Write a program in Python implement the RSA algorithm for cryptography. Set up: 1.Choose two large primes, p and q. (There are a number of sites on-line where you can find large primes.) 2.Compute n = p * q, and Φ = (p-1)(q-1). 3.Select an integer e, with 1 < e < Φ , gcd(e, Φ) = 1. 4.Compute the integer d, 1 < d < Φ such that ed ≡ 1 (mod Φ). The numbers e and d are...
Differential Geometry:
1) Give an example of two vector fields X,Y E X(R3) such that for almost all p ER3 the three tangent vectors Xp, Yp, [X,Y] are a basis, but for some p they are not. However, at those special points p the three tangent vectors Xp, Yp, [X, [X,Y]]p form a basis. (Hint: The fields X and Y may span the Martinet distribution.) 2) Prove that any pair of vector fields X,Y with property 1) cannot be tangent...
