  • Interconnection network is to provide communication among functional modules. The interconnections considered are Generalized Cube networks. Two situations are examined: a memory module is equally likely to be addressed by a processor and a processor has a favorite memory. This paper proposes the effective condition of operation in interconnection network through performance evaluation by simulation.

  • The key objective of this paper is to suggest a pilot model for mobile network interconnection charge calculation by bottom-up long-run incremental costing methodology. Interconnection issues have lately attracted considerable attention by network operators and regulators. However there is no standard by all the network operators' agreement. The costing method is an acute problem because the interconnection charge is directly related to the network operators' revenue. Thus Korea has planned to launch the new interconnection policy based on the current traffic distribution and then we simulate the model in a sample area with virtual data. The results propose objective and reasonable guideline for the mobile network element cost calculation. It can be helpful for calculating price floor or bottom-up long run incremental interconnection charge by regulator.

  • In this paper, an intelligent home network middleware interconnection adapter between devices was designed. Home network middleware interconnection adaptor is present in UPnP, LonWorks, LnCP, HAVi, etc. Various types of middleware and for use of a number of middleware is required to modify an existing system. But this study designed by middleware interconnection adaptor a number of existing middleware systems without modification was designed to allow interlocking. The Performance evaluation of designed interconnection middleware adaptor produced by various companies was used devices, experimental device was implemented. And mobile application was developed by using developed interconnection middleware adaptor. Also the performance was evaluated in a mobile application.

  • When DG interconnection into network is examined, details of the review are overvoltage, protective device malfunction, etc. In the case of protective device malfunction, replacing protective device into bi-directional protective device and installation NGR are the solution. Overvoltage at interconnection point occurs because the load is relatively less than DG output. When overvoltage at interconnection point occurs, DG interconnection is not permitted because this overvoltage affect other customers. Interconnection by installation new distribution line is one solution but it costs much money. Without installation new investment, change of NOP(Normal Open Point) position is a possible solution about DG interconnection into network.

  • In this paper we consider the performance Analysis of multistage interconnection network, which is major parts of multi-processor system. We review the Hardware configuration of STAR network system using base-line interconnection network and obtain the probability of clustering basing on analytical model. In addition, Instead of Baseline interconnection system, mentioned above, STAR network system using delta network is considered and TWO probability mentioned above is obtained, finally the comparative result is shown in the figure.

  • The number of wind generation installations are growing substantially in Jeju, Korea. Many of these installations are significant in size and directly connected to the distribution system. Utility grid interconnection standards for interconnecting non-utility distributed generation systems are essential to both power system company and generation company. These interconnection standards are important to utilities, customers, wind generation manufactures and nation. In this paper, it is investigated the voltage quality and the suitability of Jeju-Hangwon wind power generation farm by network interconnection technology standard.

  • This paper describes an interconnection network structure which transports information among processors through a high speed ATM switch. To efficiently use the high speed ATM switch for the message-based multiprocessor, we implemented the cell router that performs multiplexing and demultiplexing of cells from/to processors. In this system, we use the expanded internal cell format including 3bytes for switch routing information. This interconnection network has 3 stage routing strategies: ATM switch routing using switch routing information, cell router routing using a virtual path identifier (VPI) and cell reassembly routing using a virtual channel indentifier (VCI). The interconnection network consists of the NxN folded switch and N cell routers with the M processor interface. Therefore, the maximum number of NxM processors can be interconnected for message communication. This interconnection network using the ATM switch makes a significant improvement in terms of message passing latency and scalability. Additionally, we evaluated the transmission overhead in this interconnection network using ATM switch.

  • The present paper investigates the technological and conceptional characteristics of peering and transit in internet interconnection. Especially, the market with two ISP competing for customers is modeled and the outcome with peering is compared with transit. This paper also analyze the congestion effects on retail price and network capacity. When there is congestion effects occurring from network sharing, the retail price is increased and the fixed fee is decreased with the degree of congestion. Finally, the optimal access charge assuring the socially optimal retail price and network capacity is derived.

We investigate various topological properties of HON($C_d,C_d$), including connectivity, routing algorithm, diameter and broadcasting. We show that HON($C_d,C_d$) outperforms the three networks, i.e. the odd network, HCN(m,m), and HFN(m,m).
