Chapter 4: Mini-Cases IV Alpha Corp 1. Without considering transmission efficiency, I would recommend installing an internet source capable of transmitting 270,000 bits per second or higher for the Alpha Corp. The Alpha Corp is transmitting 1,000 emails per hour at 1,500 bytes in size, which equals 16.6 emails per minute. This then breaks down to 0.277 emails per second sending 415.5 bytes per second or 3,324 bits per second . Alpha also sends 3,000 Web pages per hour at 40,000 bytes in size, equaling 50 emails per minute or 0.833 per second. This equates to 33,333.33 bytes per second or 266,666.64 bits per second. In total, the Alpha Corp is sending 269,990.64 bits per second between their emails and web pages. Today, 1,000 emails (75KB each) and 3,000 web pages (1,246KB each) per hour would equate to 8.16Mbps needed for the Alpha Corp.'s internet connection. 2. If the Alpha Corp is using a synchronous data link layer protocol with an efficiency of about 90%, Alpha Corp. would need a minimum internet connection speed capable of transmitting 297,000 bits per second because synchronous data link layer protocol adds additional bits for error correction. The additional speed would provide enough bandwidth and throughput allowing the company to continue the business needs without heavily straining their internet connection. Today, if 1,000 emails and 3,000 web pages per hour equates to 8.16Mbps, and the Alpha Corp. began using a synchronous data link layer protocol with an efficiency of about 90%, the internet capability would need to be at a minimum of 8.98Mbps. 3. If the Alpha Corp. wants to be sure that its internet connection will provide sufficient capacity for the next two years, I would recommend installing fast Ethernet or greater technology such as fiber optics for greater bandwidth and throughput . As technology and the organization grow, so
