Connecting to the distribution layer
A national network service connection via the distribution layer helps medium-sized organisations get the best network experience. The distribution layer also provides connectivity options at locations that are not core network PoPs.
About the distribution layer
The distribution layer allows many medium-sized organisations to connect to the network more simply. The distribution layer is made up of 12 routers located at network PoPs around the country. Members connect to a router, rather than a core network switch.
Being one step removed from the core backbone of the network, this layer provides REANNZ with control of the routing decisions and of who can access the network, and provides the member with a good network experience. While the member does not need the high level of resources and expertise required for a core connection, they will need to manage the edge device at their site and secure access circuits from their site to the PoP.
Connections to the distribution layer can be made at 100 Mb/s or 1 Gb/s, and can be made at Layer 1 (optical service) or Layer 2 (Ethernet service).
Connections to the distribution layer are available to Members (Other), Associate Members, Partners, and Content and Service Providers.
NB: You must submit your signed membership agreement before embarking on connecting to the network.
The following is a general guide on costs for connecting and maintaining your connection to the distribution layer. Connection costs include the REANNZ connection fee, connection design and edge device, as well as any ongoing last mile circuit ongoing support costs. The membership fee is additional to these technical costs.
|Network designer||$100 - $200 / hr for 10 - 30 hrs|
|REANNZ connection fee||$4,200*|
|Edge router||$2,000 - $16,000|
|Edge router support||$55 - $350 / mth|
|Layer 2 fibre (100Mb/s - 1Gb/s)||$300 - $1,000 / mth|
* May increase if short range optics are not suitable. See the connection cost FAQ for more information.
To make and manage a distribution layer connection to the network, you will need to arrange physical access and logical access. There are a variety of standards that should be used when connecting. The following standards have been set to ensure the performance and integrity of the network is maintained. These standards apply to connections to the distribution layer only.
We suggest you read through the relevant Connection Form for your member type to familiarise yourself with full details of the information we ask you to provide and work that needs to be completed.
NB: You will only be connected to the network once REANNZ has received and approved your completed connection form.
Physical access to the POP
You will need an access circuit from a supplier to a PoP where there is a distribution router. Your physical access is the way in which your edge device will connect to the network PoP. This can be done at Layer 1 or Layer 2.
Connections to the PoPs should consider the following:
- Fibre optic “last mile” is preferred. The “last mile” may also be delivered as a copper based service on Cat5e or greater cabling
- LX or LHA optics depending on the measured optical loss of your access. Connections to be made at distances greater than 10km from the POP should be discussed with REANNZ before commencement
Each provider of physical services is required to install a dedicated OFDF in the REANNZ rack within the PoP. This OFDF must support one of the approved connector types:
- Angled SC (SCA) - recommended
- Angled LC (LCA)
- Copper based termination should be made on a dedicated RJ-45 panel that is mounted at the rear of the passive rack.
Physical access within the POP
Connections within the network POPs should adhere to the following standards:
- All connections to the network should be made with single mode 9/125 micron fibre optic cable or Cat5e (or greater) cable
The optical connector at your providers OFDF within the correct rack at the KAREN PoP should be one of the following:
- Angled SC (SCA) - recommended
- Angled LC (LCA)
- All electrical connections will be made using RJ-45 connectors.
- The connector at the connecting organisations equipment will depend on the selection of vendor equipment
Connections can be made to the network at the following port speeds:
- 100 Mb/s
- 1 Gb/s
The network supports IPv4, IPv6 and IPv4 multicast services. Members will need expertise and an edge router at your site that can support these services.
The following standards must be supported in order to connect through a distribution router:
- 802.1Q VLAN tagging
- IPv4 (minimum 24 bit subnet mask) or IPv6 (minimum 48 bit subnet mask) *
- Path MTU Discovery (RFC 1191 Compliant)
- BGP v4 with the ability to hold at least 20,000 routes
- Autonomous System Number (ASN)
* REANNZ may be able to offer assistance by allocating IP address space. This is dependant on your membership class.
The following options can also be used when connecting to the network:
- Multicast, which requires:
- 802.1Q VLAN tagging for private VLAN option
- Protection of BGP sessions via the TCP MD5 signature option (RFC 2385 Compliant)
- 9000 byte (Jumbo) MTU support
The technical requirements are only one part of the puzzle. To make a compliant, well performing connection, you will need a project manager and networking expertise.
You will also need either in-house or contracted ongoing network expertise to manage your connection for the long term. Some larger organisations have the internal expertise to manage their connection themselves. If you are a smaller organisation we suggest you hire someone to provide technical help. They will need to be able to:
- design your connection
- manage routing, configs and local firewall rules and performance
- diagnose and resolve performance related issues
REANNZ's network is not an ISP, and therefore, members need to have their own:
These connection forms are specific to your membership category and the type of connection you intend to make.
NB: You must submit your signed membership agreement before finally connecting to the network. You will only be connected to the network once REANNZ has received and approved your completed connection form.
