Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci
Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci
Journal of International Technology and Information Management
The Internet industry is vertically integrated with Internet Backbone Providers (IBPs) and Internet Service Providers (ISPs.) Although there are many ISPs and IBPs in each stream, both markets are considered independent oligopolies in that there are a few dominant competitors in each market. It is generally accepted that the Internet industry structure has evolved into a four-tier hierarchical structure. The synergistic and codependent nature of the Internet industry is the key element in understanding the competitive environment in which both IBP’s and ISP’s cooperate. Peering is an efficient way to exchange traffic freely within the access tier, nevertheless competitive constraints …

Application Of Uml For Modeling Urban Traffic System Using Producer Consumer Theory To Generate Process Algebra Model, Manuj Darbari, Sanjay Medhavi, Abhay Kumar Srivastava
Journal of International Technology and Information Management
UML is widely used as an industry standard for modeling any system. In this paper will be dealing with simple UML diagrams and show that low it can be transformed into process algebra models specially designated to model urban traffic systems. The model capture functionality at the level of mesoscopic as well as microscopic level and it is merged with process algebra’s producer consumer theory. The model is also formalized using Process algebra equations. This paper focuses on complex situational activity diagrams enhancing the expressivity by refining at the abstraction levels. Performance requirement is annotated by the UML profile for …
