ASN.1 SOAP messages encoded using the ASN.1 Packed Encoding Rules generally
provides for the operation of Web services that require less processing power
(and hence provide a higher transaction processing rate) and that require less
network bandwidth than use of the character encoding of XML data in conventional
Web services. This can be advantageous in a number of domains:
1. Constrained devices, such as mobile phones, smart cards or even RFIDs
(Radio-Frequency IDentification), that have limited processing power, memory and
There is no equivalent Moore's law for battery technology (battery life is
not doubling every 18 months).
2. Bandwidth restricted systems, such as wireless networks.
Radio frequencies for wireless networks, such as the mobile phone GSM network
(Global System for Mobile Communications), can be fixed for 10 years. There is
no equivalent Moore's law for radio frequencies (bandwidth is not doubling every
3. High throughput transaction systems, such as systems required to
process a required number SOAP messages per second from many clients.
Research has shown that doubling the number of network nodes can result in an
increase in the interconnections between nodes to a power of 7 or 8, which is
much larger than an increase in processing power obtained from a doubling of
transistor density. This implies many more messages that need to be processed by
systems that are increasingly being outpaced by the network.
ASN1 (Packed Encoding Rules) ni mfumo wa programu ya mtandao unaotumia data ya XML kwa njia ya encoding ya herufi. Hii inaweza kuwa na faida katika maeneo kadhaa: 1. Vifaa vya kifaa, kama vile simu za mkononi, kadi za smart au hata RFID (Radio-Frequency Identification), ambazo zina uwezo mdogo wa usindikaji, kumbukumbu, na hakuna sheria ya Moore ya teknolojia ya betri (maisha ya betri haiongezeki mara mbili kila miezi 18). 2. Uwezekano wa kupata Bandwidth mfumo mdogo, kama vile mitandao ya wireless. Vipimo vya redio kwa ajili ya mitandao ya wireless, kama vile GSM (Global System for Mobile Communications) mtandao wa simu za mkononi, inaweza kuwa fasta kwa miaka 10. Sheria ya Moore ya Frequency ya redio ni ya kawaida, lakini kwa sababu ya hali ya hewa, bandwidth ya redio inaweza kuongezeka mara mbili kila baada ya miaka mitatu. High throughput shughuli mifumo, kama vile mifumo zinahitajika kwa usindikaji wa idadi inayohitajika SOAP ujumbe kwa sekunde kutoka wateja wengi. Utafiti umeonyesha kuwa mara mbili ya idadi ya nodes mtandao inaweza kusababisha ongezeko la interconnections kati ya nodes kwa nguvu ya 7 au 8, ambayo ni kubwa zaidi kuliko ongezeko la nguvu ya usindikaji inayopatikana kutoka mara mbili ya wiani wa transistor. Hii ina maana ujumbe wengi zaidi ambayo wanahitaji kuwa kusindika na mifumo ambayo ni zaidi na zaidi kuwa outpaced na mtandao.
