As Home Networking techn

34、ology is rapidly evolving, network functions which are pre-installed in home electrical appliances can easily become obsolete and may be difficult to upgrade. Many appliances strictly limit resources such as the CPU, power capacity, and memory to achieve cost savings. If all network functions are em

35、bedded in Home Networked appliances, this could result in a higher cost for new appliances and an additional barrier to wide adoption of such systems. In addition, when consumers want to add a new appliance to the network, they are forced to choose equipment with the same interconnecting systems as

36、the existing network or add a router or gateway which can interconnect different systems. To solve these problems, the network functions are divided into two parts. Since functions from OSI layer 1 to 7 (refer to ISO/IEC 7498 in Bibliography) are necessary to network home electrical appliances (incl

37、uding both multimedia equipment and household appliances such as televisions, computers, refrigerators, washing machines, and sensors), network functions from OSI layer 1 to 6 and most of layer 7 reside in an external Network Adapter and only a small part of layer 7 resides in the home appliances. T

38、he advantages of applying this standard are: Users can upgrade a Home Network by simply changing the Network Adapters. NOTE For example, when an end-user wants to have higher QoS media. An electrical appliance without embedded network functions can be connected to an existing Home Network with a Net

39、work Adapter. NOTE For example, when an end-user wants to utilize some of the network application functions (i.e. energy conservation, etc) on an appliance which does not have all of the network function integrated. By selecting Network Adapters which use the same interconnecting system as the exist

40、ing Home Network, routers or the gateways can be avoided. NOTE 3 For example, when an end-users network is a powerline network, but the appliance the user wants to connect to has only an RF network connection. NOTE 4 For example, when an end-users network is based on home networking standard “A” (la

41、yer 1-7), but the appliance the user wants to connect utilizes a home networking standard “B” (layer 1-7). Home appliance manufacturers can produce products that can be connected to Home Networks with minimal cost increases since most of the network functions are not required to be embedded in the a

42、ppliance. NOTE This standard is helpful for standardizing the manufacturing process for including the network function in appliances- especially when the market has a low penetration of appliances that are network-ready. Device objects are based on the same object-oriented methodology used in almost

43、 all existing network protocols.
