6. 20401 Common Network Infrastructure • Current Status • Develop transport architecture • Overlay supporting network services • Rick’s recommend next step: • Identify new owner or place on hold

7. 30000 Transport Framework & Overview • Current Status • Draft PAR language reviewed with GC (see next 2 slides) • Submit to IEEE • Develop Specification • Rick’s recommend next step: • Identify new owner or place on hold

8. Proposed 30000 PAR language 2.1 Title of Standard: Standard for Health informatics - Healthcare device communication - Transport profile - Framework and overview 5.2 Scope of Proposed Standard: This document focuses on the identification and characterization of the transport services required by the upper layers of the ISO/IEEE 11073 family of standards that are to be provided by the lower layers of the ISO/IEEE 11073 family of standards. The transport services and characteristics may cover such areas as, but are not limited to, reliability, latency, bandwidth, flow control, security, media type/category, forward and reverse channel set-up/tear-down times, power consumption, device/service discovery and virtual channel usage. 5.4 Purpose of Proposed Standard: The purpose of this document is to define the overall framework for communication between the upper and lower layers of the ISO/IEEE 11073 family of standards. This document identifies logical transport services and characteristics, and as such, no particular implementation is implied by this document. To provide consistency and continuity across the different ISO/IEEE 11073-3xxyy family of standards and to assist in the understanding of these logical transport services and characteristics, representative examples of upper and lower layers from the ISO/IEEE 11073 family of standards are included. The document also summarizes the underlying transport profile specifications.

9. Proposed 30000 PAR language 5.5 Need for the Project: Healthcare devices use communications technologies in a wide range of environments including: enterprises, departments, care units, embedded point of care topologies, home and personal situations. However, efficient integration is limited by insufficient standardization at the transport layer in time-critical medical data communication contexts. 5.6 Stakeholders for the Standard: Key stakeholders include healthcare device and system developers who are incorporating communications technologies, those who sell, deploy and/or manage these systems and those organizations that regulate this environment.

12. Transport Philosophy • The following slides are from the draft ISO / IEEE 11073-30000 Framework & Overview document and provide an approach or philosophy for Transports. • The intent is to establish a consistent approach for items such as establishing requirements and referencing outside specifications. The general approach is to define requirements and then utilize application-driven profiling to accomplish, leveraging commercial technologies as much as possible.

13. Transport Philosophy 1.5.1.3 Tailoring a Standard In some cases an existing standard must be tailored in order to meet ISO/IEEE 11073 requirements. For example, there may be a unique QoS requirement that is necessary in an acute care setting. In this case, the required additive deltas should be documented in a new ISO/IEEE specification that references the specification that is being leveraged. In addition, profiling should be used to tighten optional items that may exist in the referenced specification and to provide clarification of ambiguous specification language. 1.5.2 Separate Transport from Data It is a goal to separate out Transport issues and associated specifications from Data issues and associated specifications. As much as possible, these should be independent and Transport series specifications should not create requirements that have implications for the payload data. 1.5.3 Spectrum of Implementations There is a spectrum of target environments for products that are implemented in accordance with the ISO/IEEE 11073 specifications. As such, a range of requirements should be accommodated. For example, some of the stringent error reporting requirements that are necessary in the clinical acute-care environment may not be germane to all environments.

14. Transport Philosophy 1.5.1 Leveraging Existing Commercial Standards It is a goal to avoid having redundant and possibly contradictory specifications that exist in conjunction with the ISO/IEEE 11073 series of Transport specifications. There are many commercial Transport standards available that are widely implemented and that should be leveraged to the fullest extent. To facilitate this, actions below should be considered. 1.5.1.1 Selection of Standards The standards selection process should include canvassing the industry for existing standards. Evaluation criteria should consider commonality with other medical consortiums where there may be overlap. When considering a standard to reference, preference should be given to an open industry standard that is released and sponsored by an international SDO. 1.5.1.2 Establish a Liaison For active standards, a liaison or point-of-contact should be established between ISO/IEEE 11073 and the host SDO that controls the standard to be leveraged. The liaison will be responsible for providing periodic updates to the ISO/IEEE 11073 team on the state of the specification and the plans to evolve it. The liaison will also be responsible for providing the host SDO with collective inputs from the ISO/IEEE 11073 team.
