Experimenting w/ High Performance Computing and Multicasting?
jessemersonuy asks: "Multicasting plays an important role in the design, development, operation, and application of next generation networks that rely on the efficient delivery of packets to their destinations. Due to the advent of broadband, wireless and web-based system design technologies, it has become possible and feasible to design and construct large scale, heterogeneous and complex wireline and wireless communication networks that can support multimedia conferencing, streaming media distribution, distributed data sharing, distance learning, 'push'- oriented, and QoS for wired-cable and wired-wireless applications. Now, we have a small High Performance Computing system in our university campus and I would really like to use that system for testing multicasting applications. However, I do not know what would be the best way to use the cluster for multicasting purposes. Has anyone experimented with this before? What might be the best multicasting application to use to be able to fully utilize the power of the cluster?" -

Why Are SSL Certificates So Expensive?
hip2b2 asks: "SSL over HTTP is becoming a very popular way of securing websites for eCommerce and other forms of secure transactions. A vital ingredient of a SSL protected website is an SSL certificate. In the Philippines, most of the secure website here buy their certificates from Verisign. Why should we trust a certification authority that is located in a different country and charges and arm and a leg for a certificate instead of a local one? I can pay 349USD for a Verisign or 125USD for one from Thawte, which is not cheap here. With an exchange rate of around 48.50PHP per USD, this amount is beyond the reach of most local sites who just want to setup secure sites to try out the technology or use it for some charitable purpose. How do we expect to promote the use of SSL in our websites locally with these prohibitive costs? This problem is not limited to the Philippines, I presume that other countries could also relate to this issue." Right now, the cost of an SSL certificate is one of the prices for doing business on the internet (in addition to bandwitdh costs), but what would it take to start up another company that issues CAs, especially if you want to do it outside of the US?"Is it a question of trust? Do local ecommerce and secure sites trust verisign more that say a local company that provides secure certificates? What confuses me is why is there no proliferation of trusted local institutional CAs? In the future, Verisign might end up being another Network Solutions.
Oh wait! Network Solutions is a Verisign company!
What are the barriers for setting up local country CAs? Right now, I presume that browser makers are the ones listing the trusted root CAs on their browsers by default. If my university were to setup a root CA how would we get netscape and the other browser makers to recognize us? or is there some sort of governing body for assigning root CAs like ICANN is supposed to be for name resolution? or could this be one of ICANN's eventual functions?"
