This decision process (strategy) is external to the architecture itself; for example, a company (such as a system integrator) may want to deploy VoIP internally to gain experience with that technology to then sell that to prospective customers; again note that decision process (strategy) is external to the architecture itself. Then we would have the following: I(1,2,n + 1) = 1 I(1,3, n + 1) = 1 I(1,4, n + 1) = 1 I(2,3, n + 1) = 0 I(2,4, n + 1) = 1 I(3,4, n + 1) = 0 Then: D(1,2, n + 1) = encrypted files D(1,3, n + 1) = encrypted files D(1,4, n + 1) = compressed voice files D(2,4, n + 1) = compressed voice files Then: PI(1,2, n + 1) = TCP/IP with IPSec PI(1,3, n + 1) = TCP/IP with SSL PI(1,4, n + 1) = RTP/UDP PI(2,4, n + 1) = RTP/UDP So: FB(1,n) = {F(1,n) = corporate LAN at month n, I(1,2,n) = 1, I(1,3,n) = 1, I(1,4,n) = 1, D(1,2,n) = Encrypted files, D(1,3,n) = Encrypted files, D(1,4, n + 1) = compressed voice files, PI(1,2,n) = TCP/IP with IPSec, PI(1,3,n) = TCP/IP with SSL, PI(1,4, n + 1) = RTP/UDP} FB(2,n) = {F(2,n) = corporate WAN at month n, I(2,3,n) = 0, I(2,4,n) = 1, D(2,4, n + 1) = compressed voice files, PI(2,4, n + 1) = RTP/UDP} Introduction ◾ 27 FB(3,n) = {F(3,n) = corporate extranet at month n, I(3,4,n) = 0} FB(4,n) = {F(4,n) = VoIP at month n} Finally, assume that P*(1,n) = {FB(1,n), FB(2,n), FB(3,n), FB(4,n)} (these are the data networks).
Before getting the business involved) because the business wanted proof that IT could deliver before giving up business people’s time to the effort. … Enterprise architecture has to offer more products and benefits to be accepted by the business. Architecture alone is not a viable sell. Service Oriented Architecture (SOA) is a great way to build enthusiasm for architecture among business people because it reduces IT to a vocabulary they can understand. ” Reuse becomes real and starts to impact midlevel business people directly because they can see how much faster they get new functionality from IT since “get customer” became a service in a repository that any developer can access when the need arises.
It covers detection of faults and outages, configuration, administrative accounting, performance, and security. As mentioned earlier, there are many models that can be used. 5 is loosely based on the Reference Model of Open Distributed Processing (ISO-RM-ODP) (ITU-T Rec. 901-(aka) ISO/IEC 10746-1 through ITU-T Rec. 904 (aka) ISO/IEC 10746-4), which provides a framework to support the development of standards to support distributed processing in heterogeneous environments. RM-ODP uses an object-modeling approach to describe distributed systems.
