Voice over internet protocols (VoIP)'s quality communication relies significantly on the network; however guarantee the best quality of the traffic is difficult. This paper analyzes the performance of VoIP traffic in Border Gateway Protocol (BGP) -Multiprotocol Label Switching (MPLS) IP Virtual Private Network (VPN) between two interior routing protocols namely Enhanced Interior Gateway Protocol (EIGRP) and Open Shortest Path First (OSPF). The combination of MPLS and conventional routing improve the forwarding mechanism, scalability and overall network performance. OPNET Modeler 14.5 is used to simulate both scenarios and metrics such as delay, jitter and mean opinion score (MOS) value are measured. The simulation result shows OSPF and BGP-MPLS VPN provides better infrastructure for VoIP VPN application.
Augmented Reality (AR) is a visual technology that able to provide users with a semi-real time experience. The advancement of mobile phone and camera technology have make the potential of AR emerged. Companies wants high product sales and look more advanced than their competitors. One of the effort is to provide customers with correct experience of their products. Catalog is a tool to market a product. However, paper printing catalog is two dimensional, and has limitation in fully presenting the product. This work, presents the adoption of AR in T-shirt catalog. The application utilized Android mobile phone to view the 3D model of the t-shirt. The user scan the catalog using the android handphone on the paper printing catalog, and they able to view in 3D the different angle of the T-shirt. This application has successfully developed and testing has been made on compatibility and functionality test.
