    This paper proposes the design of recursive Anycast DNS service system using as a replacement for the original unicast DNS service system that the UniNet Network is active and having problems supporting the volume of client traffic that has a large number of educational institutions. In order to increase the efficiency of providing services to clients of educational institutions. The designing from setting up the server host in various node and the designing the server connected to a suitable network for routing protocol has been proposed, including designing an emergency backup system that regards to compatibility with current network systems and the use of the original unicast DNS system to be useful. As a result of testing the designed system, it was found that the Query time of the new system was 2 times less than that of the original system for query IPv4, and 5 times less than that of the original system for query IPv6. Anycast DNS system that was installed can support the amount of DNS Query more 15 times than the original unicast DNS system.

    A new optical data transmission technique through a highly secure tunnel using a crypto carrier was investigated. High speed, high-security communication was achieved with an add/drop filter system and PANDA ring resonator optical equipment. The technique employed coding-decoding generated by public and private optical keys in frequency and time domains using a high-security tunnel. This novel technique provided high speed optical communication using light processing without electric control circuits. Restrictions on the operation of various equipment parameters affected the optical data communication signal intensity. The suitable signal ray data intensity was less than 200% of the signal ray intensity used for generating the optical public and private keys. This new technique ran and transmitted encrypted data efficiently to the receiver.

    The multi-wavelength optical network security system generated by using an optical nonlinear material within the modified add-drop optical filter for network security is proposed. By using the dark-bright nonlinear pulse control, the optical multi-wavelength can be constructed and applied to securely transport within the network. The advantage is that the dark and bright nonlinear pair (components) can securely propagate for long distance without electromagnetic interference. In operation, the optical intensity from modified add-drop optical filter is established.

    A novel design of Terahertz (THz) switching generation for high speed computer used is proposed. The dense wavelength division multiplexing (DWDM) can be obtained by using a Gaussian or Soliton pluses propagating within a modified add-drop filter know as a PANDA ring resonator. The THz devices can made contributions to promising applications in high-speed switching, demultiplexing, and wavelength conversion of optical signals. Effective THz control is also essential for the potential application to ultrahigh-speed wireless digital interconnects for computer chips of the ultrahigh clock rates (> 10 GHz). In principle, the high density frequency (wavelength) can be generated and used to form the radio frequency identification (RFID), Ad-Hoc network and ubiquitous applications, moreover, the tiny device system is the another advantage, which can be constructed incorporating the available currently used system. In this paper is organized as follow: introduction, theory and the use of such a system in all proposed applications.

    In this paper, we present a new concept of all-optical gates using Dark-Bright soliton conversion behaviors within a modified add/drop filter. The soliton can be used to generate logic data "1" and "0" using for optical gates. We have designed a photonic circuit for all-optical logic NAND Gate using dark-bright soliton conversion control within an optical add-drop multiplexer. The input and control logic ̀0', ̀1' are represented by dark (D) and bright (B) soliton pulses, respectively. We found that the simultaneous optical logic NAND Gate at the through port can be performed.
