The Hybrid TCP/IP-Os Standards architecture
4. The Hybrid TCP/IP-OSI Standards Architecture
Standards Architecture a Standards architecture is a broad plan for Creating standards Break the problem of effective communication into smaller pieces for ease of development Develop standards for the individual pieces Just as a building architect creating a general plan for a house before designing the individual rooms in detail The dominant architecture today is the hybrid TCP/IP- osi standards architecture shown in the next slide 2-27
2-27 Standards Architecture • A Standards Architecture is a Broad Plan for Creating Standards – Break the problem of effective communication into smaller pieces for ease of development – Develop standards for the individual pieces – Just as a building architect creating a general plan for a house before designing the individual rooms in detail – The dominant architecture today is the hybrid TCP/IPOSI standards architecture shown in the next slide
