During discussions of a document to provide a standard representation and encoding of Domain-Sequence within the Path Computation Element (PCE) communication Protocol (PCEP) for communications between a Path Computation Client (PCC) and a PCE, or between two PCEs. It was determined that there was a need for clarification with respect to the ordered nature of the Include Route Object (IRO). Since there was a proposal to have a new IRO type with ordering, as well as handling of Loose bit (L-Bit), it felt necessary to conduct a survey of the existing and planned implementations. This document summarizes the survey questions and captures the results. Some conclusions are also presented. This survey was informal and conducted via email. Responses were collected and anonymized by the PCE working group chairs.
