Executive Summary

• DTS uses Internet technologies to facilitate real time data exchange and transaction processing

• DTS builds on stable technologies, not specific products

• DTS, once implemented, reduces programming and per-transaction costs through standardization

DTS Defined• Data Transport Standard• Established by PESC for exchanging data:

– Inquiry– Reports– Transactions

• An adjunct to or replacement for existing data transport mechanisms (PGP, Secret Agent, e-mail and FTP)

Specification for DTS

• Specification Covers– Technical interchange rules and processes– Recommended best practices

• Specification Does Not Cover– Business rules for transaction processing– Operational oversight, monitoring or escalation

• Implementation Examples– Code samples are available

DTS Benefits

• A Web Services implementation – Delivery confirmation included - no guessing– All requests get a response– All submissions get an answer of some kind

• Facilitates real time data exchange• Includes automatic data encryption• Uses digital signature standards• Platform independent• Strong authentication with non-repudiation

Next Steps

• Identify business partners or internal applications seeking real time data exchange

• Support the standard by funding and scheduling implementation of DTS

• Implement DTS

• Monitor improvements in throughput and reductions in transaction cost

Share Information

• Notify the PESC DTS Workgroup with– Implementation and testing schedules– Trading partners– Issues with the defined standard

• Share Implementation Experiences with Community– Successes– Difficulties

Data Transport – Issues• E-mail data exchange is not reliable or flexible enough

– No guarantee of delivery– No guarantee of order of delivery for sequence dependent data– No automatic confirmation of receipt or facility for retransmit– No synchronous response available– Email size limitations

• FTP data exchange has own challenges– Possible to overwrite earlier files– No confirmation of receipt– No synchronous response

• Encryption is always separate and subject to its own issues, maintenance and failures

DTS Addresses Transport Issues

• DTS addresses – the confirmation issue with a send-receive protocol –

confirmation is built in– the order of delivery problem by actively delivering and

receiving the data – no unconfirmed hand-offs– the size problem through data compression– the FTP overwrite problem by not using filenames– the lack of a synchronous response by building in a

required synchronous response, even if only for handling status

– the encryption issue by using standard HTTPS for encryption – the same technology as for online banking

DTS Technologies

• Standards– HTTP1.1, SSL2.0, SOAP1.1, XML, WSDL2.0, zLib (RFC

1950), Base64 (RFC 3548), UUID, X.509– This suite is generally accepted as the base set of

standards for building a Web Services solution

• SSL encryption of HTTP Streams• WS-Security / XML-DSIG – digital signature

standards– Strong authentication with non-repudiation– X.509 encryption keys and certificate authorities
