Update on Interconnect Numbers and Locations

The NGNuk paper on Interconnects identified 7 areas of concerns. These and their status prior to the meeting are as follows:

  • Metro Parenting - CPs are still having difficulty obtaining the relevant data due to issues associated with the NDA. C21 believe this is close to resolution.
  • Additional and Substitutional Nodes - NGNuk were seeking feedback to allow iteration prior to any activity via Consult 21. An update was provided by BTW and is covered below
  • Foreclosure - The NGNuk working group do not believe that this has been addressed.
  • Product information on what products or services are interconnected where is outstanding but is covered in part below.
  • Impact on wBC  is outstanding
  • Equivalence - the working group had asked that BTW review on equivalence widen its scope to consider the impact of multi media
  • Cost information - this action now sits with NGNuk

BTW (John Morden) provided the following responses:

Non-Core Interconnect Nodes

The additional nodes suggested by NGNuk would all need additional equipment at each site as the existing design assumes tromboning via the core and also to increase availability levels. Physical security improvements ( such as building hardening) would not be undertaken)

Of the sites suggested by NGNuk 10 were suitable as interconnect nodes. One sites was suggested as an alternative by BTW and one has no accommodation available until 2010.

Overall if all sites were adopted it would increase BTW capex costs by £30m. Of this amount a disproportionate amount is driven by two sites.

There was some debate regarding who should pick up the costs of an additional node where this was only required by one CP or few. The consensus was generally under such circumstances that these costs should be borne by the connecting CP.

Action 1 - 26/04/2007 - NGNuk requested any outline information that might be available on the impact on opex costs rather than just capex.  BTW.

BTW requested that NGNuk consider the information provided ASAP as they wished to initiate any review via Consult 21 to finalise any design changes as soon as possible.

Action 2 - 26/04/2007 - Work group to respond to BTW by mid May regarding the additional information provided.

Proposed Substitute Core Sites

Three alternative core sites had been suggested by NGNuk.

BTW reviewed the physical requirements of the core nodes and demonstrated that there were issues with all three NGNuk suggestions.

BTW suggested that providing a "virtual" interconnect might be an option where they cover the conveyance to the core site. In addition they raised the question of whether  interconnect nodes  needed the same level of resilience or hardening as Core Nodes. The Exec felt that this was not the case but deferred the matter to the commercial work group to consider further.

Openreach Ethernet Products

An overview of the Openreach Ethernet Products was provided by BTW however it was felt that it would be more appropriately discussed/presented by someone from Openreach. A concern over equivalence issues between BT and CPs was raised by Neil McArthur (CPW/Opal) though it was agreed as being outside the scope of NGNuk

Action 3 - 26/04/2007 - Secretariat to arrange that Openreach attend to provide detail of where the Openreach products will interconnect.

Foreclosure

The issue of foreclosure is a concern to CPs. The issue of concern is who bears the cost where it would have been more efficient in retrospect to have a design which had incorporated the new requirements upfront. This is especially important with respect to the "undertakings".  BTW maintained that additional nodes can be added later and that doing so at this time added cost to meet a requirement that was as yet unknown

Requirements Activity

End-to-End Requirements Definition

The latest draft of the E2E requirements had been put on the web site and public comments been invited.

Interconnect Requirements

Requests for feedback on the draft interconnect requirements were requested by 13th April. By 18th April only 6 responses had been received (BTW, Colt, Thus, CW,  SKY/Easynet and T-Mobile).

It was stressed that there was an expectation that all members should comment even if this was only to confirm that Interconnect Requirements that no comments would be submitted.

Action 4 - 26/04/2007 - all members should comment on the Interconnect Requirements even if only to confirm that no comments would be submitted by 11th May

The current status can be summarised as follows:

  • Meetings to clarify responses from NGNuk Members would be held to the end of May
  • Meetings to clarify requirements with other interested parties to be held to the end of May
  • Need for workshops/clarification activity required on Security and VPNs (MPLS)

Anticipated revised draft mid May with availability to public early June

Programme Scope

A number of potential work programmes were presented to the Exec. The Exec was asked to consider whether the programme was:

  • In or out of scope?
  • Who should take the lead, NGNuk or NICC?
  • The prioritisation of the work programme

The Secretariat raised the concern that CPs had provided limited input in assisting to developing the scope document or in commenting on the contents when circulated.

The debate was preceded by a discussion of the general status of the activity surrounding NGN roll out. A view was expressed that some of the difficulties being experienced by NGNuk in engaging the CPs reflected the fact that network roll out was delayed. The focus was therefore on the network issues rather than how to engage commercially. In addition it was felt that the focus would be less on the "new" services rather on how to transfer the existing products and services to the new networks. These views tended to suggest focusing in a few key areas rather than a wide spread of activity.

The projects were agreed as follows :

 HIGH

  • End-to-End Requirements Specification (Secretariat sponsor)

  • Interconnect Services Specification (Secretariat sponsor)
  • Voice Charging model and Framework (Secretariat sponsor)
  • Interconnect Numbers and Locations (Secretariat)
  • Authentication (Phil Male, Thus)
  • Service Specification for Real Time Voice ( no owner agreed)

Due to the wide variance between the resources identified for Voice vs. Data it was agreed that as a matter of urgency a review and comparison of the two approaches should be undertaken to identify the underlying causes.

Action 5 - 26/04/2007 - Secretariat to arrange a review of the two approaches to data and voice service spec scope with the authors

  • Service Specification for Data (Alireza Mahmoodshahi, COLT)
  • Definition of Terms ( Secretariat) - Secretariat to outsource to standards expert
  • MPLS/VPN Scope ( Phil Male, Thus)

To top

MEDIUM

  • Cost Modeling ( Andy May, C&W)

Action 6 - 26/04/2007 - Andy May to review existing action to reflect skepticism that CPs would provide adequate data and adjust as appropriate. To review with Phil Kirby prior to wider circulation.

  • Numbering and Addressing ( Justin Fielder, Sky/Easynet )
  • Presence and Location (Angus Flett, BT)
  • Service Specification for Real Time (Other) ( Angus Flett, BT)
  • Service Specification Near Real Time and Streaming (Angus Flett, BT)

LOW   

These actions would be deferred and no action will be taken at this time.

  • OA&M
  • Billing
  • Provisioning
  • Other Service Charge Model and Framework

Note: Evidence to date indicates that progress on new services is problematic. Whilst it is accepted that this work package is important it is not seen as practical to commence activity at this time.

NICC  

 The following work package items will be requested of NICC:

  • Layer 1 Transport Definition
  • QoS
  • Session Control
  • PSTN to VoIP inter working

Next Steps                

The Exec sponsors will identify a project lead and produce a more detailed work stream plan by 11th May. A template in line with PRINCE2 methodology will be issued by the Secretariat.

These will be reviewed by the Programme Board and then consolidated into an overall plan. It is hoped to review this with NICC prior to the next Exec.

AOB

Membership Application

The application from Exponential-e to join NGNuk as a participating member was accepted.

Charging Paper

A draft of the external paper by Richard Cadman (SPC Network) to present the NGNuk view on charge models had been circulated to the Exec. Comments were being sought with a view to presenting a final version for agreement during the week commencing 8th May.
