ADDRESS RESOLUTION WITH TABLE LOOKUP:
Resolution needs data structure that has information about address binding. A distinct address-binding table is used for every physical network. The major advantage of the table lookup function is generality; a table can save the address bindings for an arbitrary set of devices.
For less than a dozen receivers, a continuous search can suffice. For bigger networks the sequential method uses too much CPU time. In the figure below the hardware addresses for their corresponding IP addresses are shown.
Problem (a) Below is a capture of an Ethernet II frame which contains an IPv4 packet and a TCP segment. The second screen capture is from the data portion of the frame.
ADDRESS RESOLUTION WITH CLOSED-FORM COMPUTATION For networks use reliable addressing, it is possible to select an address that creates closed-form address resolution possible.
(a) Briefly explain the following security goals provided by cryptography: confidentiality, authentication, integrity and non-repudiation. (b) State Kerckhoff's Princip

IPv6 ADDRESSING IPv6 has 128-bit addresses. A 128-bit address adds network prefix and host suffix. An benefit of IPv6 addressing is that there is address classes i.e. prefix/s
Cryptographic algorithms Cryptographic algorithms are broadly classified into two broad categories. They are stated below 1. Symmetric Encryption and 2. Asymmetric Encryptio
