Next-generation Core Networking
Many service providers are planning for 80 percent or more year-over-year backbone growth. This growth is primarily driven by video traffic demands, but converged voice, business, and legacy data services also contribute to the increase. To maximize their revenue potential, service providers must deliver new services to market quickly while providing an excellent user experience.
The Juniper next-generation network (NGN) core routing portfolio provides market-leading, terabit-scale, end-to-end control to enable a high-quality user experience with unique investment protection and low total cost of ownership. Juniper Networks JUNOS® Software, the industry's most trusted networking operating system, powers all M Series Multiservice Edge Routers and T Series Core Routers found in the NGN core. In addition, the Juniper Networks JCS1200 Control System independently scales control plane resources enabling unprecedented levels of scale without impacting the forwarding plane capacity of T Series routers. This unique networking solution provides increased control of services, rapid deployment of service, and high operational efficiency.
The Juniper NGN core solution for service providers builds scalability and flexibility into the core network. Juniper routing platforms in the NGN core network—the Juniper M-series for small to mid-sized core networks and T-series for mid to large core networks—interwork with the Session and Resource Controllers (SRCs) at the policy layer. Together they deliver the scale, service-awareness, and a simplified upgrade path to an NGN with the agility required to enable multiplay services at scale across the core.
Unique Application: Content Optimized Core for Video
The above diagram illustrates how NGN core services can be dynamically established and/or changed based on service layer requirements. For example, video service demands can change bandwidth with 'Liquid LSPs'.

This next generation networking solution brochure describes how Juniper Networks builds service-aware networks that help service providers meet the demands of scalability the need to deliver an assured user experience.
Advanced Feature Support with JUNOS Software
JUNOS® software, the industry's most trusted networking operating system, powers all M-series and T-series routers to provide a rich set of features to support differentiated service classes for IPv4, IPv6, and MPLS traffic. This next generation networking system suits the real-time requirements for multiplay services-including voice and video content delivery-from a packet forwarding and reliability standpoint. A Juniper NGN core supports advanced features such as point-to-multipoint label switched paths (P2MP LSPs), providing the ideal solution for delivering video across the network core and distribution layers. P2MP LSPs provide video traffic with a bandwidth reservation, traffic engineering capabilities, and fast failover mechanisms that are not found in multicast protocols such as PIM or IGMP. With the Juniper Session and Resource Control (SRC) portfolio, Diffserv-aware traffic-engineered paths and advanced Quality of Service (QoS) with intelligent admission control are open to policy-based control.
Policy and Control Using Session Resource Controllers
Juniper's Session and Resource Control (SRC) portfolio provides the industry's only real-time, end-to-end policy management capabilities. The Juniper partner ecosystem brings together the richest set of application and Operations Support Systems (OSS) partners to interwork with the SRC policy manager to drive the NGN core network.
Tight Optical Integration
The Juniper NGN core includes key features to allow tight interworking with optical networks to reduce total capital expenditure and manage operational costs. JUNOS supports industry leading and open Generalized MPLS (GMPLS) capabilities for control of similarly capable optical platforms.
The T-series also includes a range of interfaces which simplify interconnection with optical networks. For example, the ability to use any XFP, 40Gbps OC-768 inverse multiplexer over installed 10 Gbps infrastructure and tunable wavelengths on 10 GE interfaces.

Service-aware Core Simplifies Network Architecture
Today, many networks have limited service control that is applied only at the network edge for control of basic Internet services and as defined in architectural models such as the IP Multimedia Subsystem (IMS). Traffic is then forwarded into a core 'cloud' with lower levels of control over the traffic and the user experience. This traditional networking core, unaware of the applications and services it is supporting, forces video services to be inserted closer to the edge to ensure high quality. However, this can limit access to long tail content (accessed with lower frequency) and service velocity.
With the Juniper service-aware NGN core, QoS and bandwidth is dynamically adjusted to accommodate video streams and other service demands. Features such as P2MP LSPs allow scalable replication of traffic across the network core. Combining these features can simplify the overall network architecture. For example, servers hosting long tail content can remain in fewer centralized datacenters serving content with end-to-end control across the core network to the user. Service velocity is improved, and rather than distributing a new unproven application to many sites, the new application can be centralized and core resources made dynamically available to deliver the service with guarantees.
"As we accelerate the build-out of our 21st Century Next Generation Network and transition to an IP-based world where services are applications, we're empowering end-users with control, choice and flexibility like never before. The new Juniper T1600 multi-terabit core router will allow us to increase network capacity in line with escalating service demands without adding incremental systems to the network so that we can speed new service deployment, deliver a superior end-user experience and maximize our existing T-series investments to meet our cost transformation objectives."
Matt Bross, BT Group Chief Technology Officer
"...it is important for core router vendors to extend the product lifecycle, reach new scalability thresholds and provide low-cost, non-disruptive upgrades for deployed systems. Juniper meets these requirements with the introduction of the T1600."
Mark Bieberich, Vice President, Enabling Technologies, Service Provider Infrastructure Solutions at Yankee Group
"It's been taken as classical wisdom that you have to do all the service-aware handling of traffic at the network's edge, but that's really just an excuse for lack of policy control that can scale to high traffic levels... The best network solution is one that knows your traffic from end to end, at every point where it's touched by resources. That's the solution Juniper's providing."
Tom Nolle, President of CIMI Corporation, a Voorhees NJ consultancy
"...the T-1600 has some real core differentiators with the increased capacity capabilities. The 100 gigabits per slot is clearly a leading feature out in the marketplace...no one has been able to get this type of density all in that small of a form factor with the incredible reduction in power."
