– On some Marketplace locations we added the MPLS router to handle the backbone connections

backbone connections

• Brocade FastIron SX, SuperX, Fesx and ICX as Edge switches

– SX and ICX are the current used switches

The NDIX network cont.

• MRV for active WDM and signal regeneration

– Media conversion: Converting normal optical signal to WDM optical signal

Latest developments

Migrating to a new network topology

Latest develoments cont.

Western ring

Almost 60 locations make the NDIX network. Creation of multiple network rings

CORE ring Three southern rings Middle ring Eastern ring

Latest develoments cont.

Upscaling locations to Semi-CORE locations

• growing number of NDIX Marketplaces

• growing number of backbone connections

• growing demand of bandwidth (multiple 10Gbps connections)

Brocade NetIron MLX serie routers just like our CORE routers

• Chassis based router

International carriers

More and more international carriers

connected with NDIX

• euNetworks • VTL WaveNet • Cogent

• Negotiations with level3 are in progress

Connecting customers to the NDIX network

Certified to MEF standards

Facts

• Over 70% of our network locations are connected to our backbone with a minimum of 10Gbps.

• Round a bout 45% of our locations have 20Gbps or more available

available

• The actual used bandwidth of our backbone connections is below the 25%

– This guarantees a NON-blocking network

• At the beginning of this year we upgraded our network to support a MTU of 9100 octets (jumbo frame support)

– Standard Ethernet supports only 1500 octets of data in a frame

– Possibility to transport more data at once this gives a higher throughput

• We are investigating the possibilities to support Q-in-Q tunnels (IEEE 802.1ad)

Increasing the availability of

our network

A couple of principles

• Effectively use the available networkrings in our network

• Standard Layer 2 VLANs (Virtual networks) to create • Standard Layer 2 VLANs (Virtual networks) to create

customer connections

• Automated restore of customer connections in case of a network problem (.. Fiber breakage)

– In the old Layer2 network VLANs had a predefined route through the network

– Reconfiguring/Restoring hundreds of VLAN connections manually takes to must time

Increasing the availability of

our network cont.

NDIX has an open network and maintains a strict separation of infrastructure and services. Therefor NDIX only operates in the first two of seven layers of the OSI-model

Physical Link Network Transport Session Presentation Application 2 1 3 4 5 6 7 NDIX VLANs / Mac-adress IP TCP Infrastructure Services

Increasing the availability of

our network cont.

• We needed a network protocol that automatically and instantly reroutes customer connections over the

remaining and available network connections

• And we cannot use traditional routing protocols to reroute customer connections because they operate at layer 3 of the OSI-model

Increasing the availability of

our network cont.

Application 7

We found a protocol suited to transport VLANs through a routed network and that is MPLS (Multi Protocol Label Switching) Physical Link Network Transport Session Presentation Application 2 1 3 4 5 6 7 NDIX VLANs / Mac-adress IP TCP Infrastructure Services MPLS 2,5

Increasing the availability of

our network cont.

A MPLS network: how does it work?

• With MPLS a tunnel is created to transport customer connections (VLANs) through the MPLS network

(VLANs) through the MPLS network

• Every MPLS router has an unique Router-ID that is used as destination for the tunnel

• Every MPLS router keeps track how to get to the destination in the most efficient way

• So how the tunnel runs through the MPLS network is decided by the MPLS network itself (no NOC interference)

How does MPLS

work for NDIX

our network cont.

MPLS NETWORK Customer Service Provider Router-ID 10.10.10.4

Increasing the availability of

our network cont.

Advantages of a MPLS network

• The network is less affected by fiber maintenance and network defects

• Uptime guarantee of connections through our MPLS network increases to five nines (99.999%)

– This does not include the local tail to the customer. If the customer wants to have higher availability we can make that possible

NDIX and WDM techniques

What is WDM?

• Wavelength-division multiplexing

• Multiplexing a number of optics signals to a

• Multiplexing a number of optics signals to a

single optical fiber using different

wavelengths

WDM optics

↓ Multiplexer

Fiber pair one for A to B And one for B to A

Multiplexer ↓

WDM optics

NDIX and WDM techniques cont.

• There are two kinds of WDM

– CWDM (Coarse WDM) – DWDM (Dense WDM)

• CWDM has limitation of 16 channels short

range and 8 channels long range

• DWDM has up to 160 channels short and

long range (160 only if fiber conditions are

perfect)

NDIX and WDM techniques cont.

WDM advantages

• Easy to upgrade bandwidth of a network connection (Upgrade to 20Gbps link by adding an extra 10Gpbs) • Less expensive fibers needed

• In combination with MPLS extreme flexibility building temporarily connections for maintenance purposes • Possibility to build dedicated customer connections

NDIX and WDM techniques cont.

• At the end of 2014 we are aiming to have

80% of the NDIX network connections

converted to WDM

converted to WDM

• All existing CWDM will in time be converted to

DWDM

NDIX and WIFI

NDIX is expanding its network wireless.

• First project in the center of Enschede (Still in progress)

NDIX and WIFI cont.

NDIX is expanding its network wireless.

• Maintaining separation of infrastructure and services • Maintaining separation of infrastructure and services

by using wireless networks (SSID’s) as VLAN’s • One SSID used for offering internet

• Open network… Multiple SSID’s available for other services

• Professional 24*7 support

• The success of this project will determine if we continue with WIFI

Customer-premises

equipment

• More and more NDIX customers using NDIX CPE’s

– Moving demarcation point from the customerport at the NDIX POP to the customer location

– In case of connection problems. One contact (out NOC) for the total connection between customer and other

customers/Service Providers – 24*7 NOC support

– Rate limiting on VLAN level

– Ability to connect a primary and a secondary NDIX

connection. Automatic failover in case of link-loss. (special type of CPE needed)

– Easier to use NDIX connection with multiple Service Providers

Customer-premises

equipment cont.

Four types of CPE’s available

• Genexis DRG711

– 4 10/100/1000 Copper ports

Customer-premises

equipment cont.

• MRV OptiSwitch 606

– 100Mbps version and a 1Gbps version available

– 4 10/100/(1000) Copper ports – Rack mountable

– Rack mountable

Customer-premises

equipment cont.

• Approximately 95% of all failures on the NDIX network is a result of Fiber breakage

• We can offer redundant NDIX connection and automated failover in case of link failure using port reflection (LIN - Link integrity)

integrity)

Service Provider

Customer-premises

equipment cont.

• Connections are increasingly becoming a

part of real estate

– Property developers and building owners can become a NDIX Business-Complex-CPE (NDIX become a NDIX Business-Complex-CPE (NDIX mini POP)

– Up to 10 customer ports (Fiber or Copper)

Professionalization internal

NDIX processes and support

• Due to rapid growth and priority of a large number of network technical improvements the improvement of internal processes were slightly left behind

• We’re rapidly improving our internal processes and • We’re rapidly improving our internal processes and

service management

– Improved change management

– Tighter protocols regarding the delivery of customer connections

– More process-based approach for network management – Uniform communication with the customer (working

according to a fixed-mail templates)

Continuity Improvements

• Increase uptime NDIX locations in case of a power failure by purchasing mobile emergency power

generator

– For NDIX locations without a no break system – For NDIX locations without a no break system

• Together with TReNT we are investigating the possibilities of an EMERGENCY POP

– Mobile container

– Multiple Telco Fiber patchracks

– More then 300 meter Fiber backbone cable – Fully equipped NDIX POP

– Emergency power generator

– First network connection restore within 8 hours. Full functionality restore within 24 hours

We think availability, continuity and quality

Is there any functionality missing?
