3 NGNBN OpCo Network Requirement High Uplink, Downlink Access Speed Open Access, Reliable, Scalable, Secure and Upgradeable Network Support fair and equitable bandwidth allocation for multiple RSP and different types of applications Support 4 classes of service Network must be capable of efficiently handling increasing high bandwidth applications such as VOD and Peer to Peer traffic Network needs to be transparent to RSP IPv4/v6 addressing scheme for all services if a Layer 2 backhaul method is selected Network must provide flexibility to enable the growth of the end user bandwidth

4 Nucleus Connect Overview Nucleus Connect was selected to Build and Operate the Active Network in Singapore s Next Generation National Broadband Network (Next Gen NBN) Nucleus Connect will deploy advanced technologies to enable a comprehensive range of ultra-high speed wholesale broadband services to RSPs Nucleus Connect will launch commercial operations in Q1, 2010 Nucleus Connect will offer standard pricing to all Retail Service Providers (RSPs) through an Inter Connect Offering (ICO) that will be regulated by IDA. Nucleus Connect will deploy a Fiber-to-the-Home (FTTH) architecture using GPON and Active Ethernet network elements to deliver broadband services with speeds up to 1Gbps

16 IP Multi-Cast Connection Service This service allows RSPs to deliver IP multicast content over the NGNBN using Nucleus Connect s IP multicast technology The IP Multicast technology is used to efficiently deliver bandwidth-intensive video broadcasting services such as IPTV Web seminar E-learning, and a host of other business applications. Using Multicast technology, an RSP offering IPTV can multicast its broadcast channels to the Nucleus PE Routers. With all the Broadcast channels replicated across the MPLS PE Routers, the RSP does not need to scale its core capacity requirements as its actual subscriber numbers grow.

23 Resiliency and Redundancy The proposed network is designed with 99.95% monthly network availability to meet the stringent QoS targets offered in the ICO. All Core, Aggregation and Access Equipment are configured with redundant configuration, including Controller cards; Switching fabric cards; Power supply modules; and Fan modules. Failure on any active components will automatically trigger a switchover to the backup cards/modules without service disruption.

25 Quality of Service RSPs will be able to offer different QoS levels to their customers at both L2 & L3. They can control this by; Class of Service for each service Amount of CIR and PIR on the uplink and downlink Dimensioning of the core and upstream capacity Network Design plays a key role Network Dimensioning o o o Coping with bursty nature of IP flows IP classification and differentiation of different service types Video, VoIP, High Speed Internet (HSI) Service and Network Availability o o Network resiliency High Service Availability in the Network Equipment GE Per Sub VLAN Per Sub VLAN VoIP Vide HSI o VoIP Vide HSI o Nucleus Connect will provide RSPs QoS information on a segment basis (End user, core network, and Network access)

27 List of Service Ports Nucleus Connect will provide Service Ports to RSP at the following locations: 1)at the PE router facing RSP at Nucleus Connect s CO - for RSP to achieve nation-wide coverage easily; 1GE and 10GE ports, single-mode fiber; 2) at the Aggregation Edge router at OpenNet s CO for example: for RSPs providing IPTV and services requiring low-latency; 1GE and 10GE ports, singlemode fiber; and 3) at the NTE at End-User Premises for the RSP s End-User to consume services. Ports are 100/1000 Mbps, electrical RJ-45, cat 5/5e UTP cable, based on GPON or Active Ethernet. NTE for GPON NTE for Active Ethernet

28 Service Transparency The proposed Nucleus Connect network (GPON or Active Ethernet) will be transparent to the delivery of the following RSP services:- IPv4 and IPv6 Protocol; IPv4 and IPv6 Layer 3 VPN; IPv4/IPv6 Unicast, Multicast and Broadcast traffic co-existence on the similar platform; Traffic segregation and prioritization; Support various packet sizes varying from 64 to 9000 bytes; Transparently proxy/relay or transparently pass through the authentication protocol to RSPs; Support private circuit security tunneling protocol like IPSec and QinQ
