XRN4991 - Enabling large scale utilisation of Class 3 – MOD0700 SPC Volume Management

SPC Volume Management Xoserve is continuing to utilise the existing maximum daily volume as started in the UK Link Manual e.g. 26k, to allocate Class Change capacity Additional volume may be available dependant on the time of day shippers submit files The current estimated demand, to migrate to Class 3, received from the industry, is within the above limits when smeared across a given month Business as Usual (BaU) use of the SPC file is minimal and Xoserve are confident this can be managed alongside the Class Change activity (based on supplied information) It has been requested from DSG members to advise Xoserve of any planned activity above normal BaU e.g. data cleanse such as MRF updates, so this volume can be accounted for The Shipper advice on the next slide should also be taken into account DSG members have been advised that only those performing Class 3 migration will be subject to limitations on the number of files being submitted Based on current data, no limits will be set on any party Xoserve are actively monitoring the volume of class changes being processed and where this either exceeds a shippers forecast volume or is from a shipper who has not submitted a forecast, the Customer Advocate will contact them, discuss requirements and, potentially, set a limit to enforce the allowed volume and thus protect UK Link Where a shipper under utilises their allowed volume by an amount that, when smeared, will breach the industry available capacity, the customer advocate will discuss how to re-plan their activity Impact assessments are ongoing to evaluate system impacts on processing SPC files across a weekend and also the resultant required actions from shippers to use this option

SPC Advice For Shippers Keep Xoserve updated with any changes to your expected SPC usage Especially important for bulk Class 3 migration but also for any other activity that would be consider above normal BaU usage Contact your Customer Advocate to discuss Submit files as early in the day as you can, this will give Xoserve the best opportunity to process the required volume First job runs at 7am If possible, complete BaU activity first i.e. non Class 3 migration This will mean IF files have to be rejected, the likelihood will be that requests such as Capacity changes, will be processed Smear Class Change effective dates Processing the SPC records is just the first step of the process, if large volumes of class changes are set to become effective on the same date this WILL adversely impact on UK Link
