Overview

Advanced routing consists of sophisticated

capabilities in MPLS network virtualization, low

latency Multicast, carrier-class reliability, quality of

service (QoS), and security. This brochure discusses

Junipers advanced routing features and solutions in

detail; showing how they can help enterprises satisfy

business drivers and improve competitive advantages.

Many of todays high-performance businesses use

their network as a competitive tool:

New York Stock Exchange uses MPLS network

virtualization to reduce network latency and improve

trading execution.

ESnet (U.S. Department of Energy) provides 5 nines

of network reliability using traffic engineering and QoS

to support critical scientific applications.

Laboratory of Neuro Imaging at UCLA uses its

network to support high bandwidth research

applications.

Junipers high-performance networking solutions

are deployed at 99 of the Fortune 100 companies,

including the worlds largest government, defense,

intelligence, and civilian agencies, and higher

education institutions.

As the high-performance network has become

mission critical, managing and securing the enterprise

network has presented increasing challenges.

Challenges

CIOs and network managers need to ensure that their networks must:

Protect against increased security risks such as malware and can safely transport data

Support transport of delay sensitive traffic that is critical to sustaining competitive

advantage

Be flexible to support network expansion

Support the prioriti zation of application bandwidth

Protect against both hardware and software failures to ensure business continuity

TrendsMany enterprises are attempting to address these challenges using complex legacy practices:

Proliferating security devices:To protect the network from security risks, many

enterprises deploy ad hoc security solutions that result in the proliferation of security

devices. This has complicated network management, increased latency, and adversely

affected performance of delay sensitive applications.

Increasing expense of redundant hardware:In addition to safeguarding the network

from security risks, some enterprises protect access to mission critical data by

deploying expensive redundant links and hardware. In many cases these redundant links

and hardware are underutilized, resulting in suboptimal resource allocation.

Expanding of legacy three-tiered network architecture:Enterprises are also expanding

the legacy multitiered data center network to support increased traffic. This expansion

not only increases management costs and wastes energy, but it also makes the network

inflexible in adapting to changing business needs.

For simplification, Juniper has created a foundation that starts with innovative advanced

silicon and hardware such as the Junos Trio chipset and offers scalability in three

dimensions (subscriber, bandwidth, and services). Junipers advanced hardware is

supported by a single OSJuniper Networks Junos operating systemand a single

release train across routing, switching, and security platforms. The powerful Junos OS

contains Junipers advanced routing solutions portfolio and enables a two-tier collapsed

architecture that supports greening of the network:

Reduces OpExby reducing power consumption, cooling, and the number of

software releases

Reduces CapExby requiring fewer devices and space

Business Drivers and Junipers Advanced

Routing Features

Junipers routers are designed to address many different business drivers. Figure 2

highlights typical IT business drivers in the enterprise and the advanced features that

address those drivers.

Figure 2: Business drivers and advanced features needed to address todays network challenges

The Need for Advanced Features

In order to address the challenges facing enterprises, high-end routers must evolve from

a device dedicated to connecting disparate networks to an intelligent and integrated

services device capable of multiple functions beyond fundamental routing.

Below are the advanced features that Juniper employs to meet this challenge.

1. Business AgilityMPLS Network VirtualizationMPLS provides a cost-effective solution for supporting several groups of users with

dissimilar requirements without building and maintaining redundant networks. MPLS

enables one physical network to be configured and operate as many separate virtual

networks with Layer 2 or Layer 3 VPN services, while maintaining security, QoS, and

latency requirements for critical applications. MPLS allows enterprises to quickly set up a

network to adapt to changing business needs.

MPLS brings the benefits of circuits to IP as shown in the figure to the right:

Supporting network segmentation and privacy

Enhanci ng the end user application experience with traffic engineering that enables

fine-tuning of the network to deliver appropriate levels of QoS

Improving network resiliency with features like MPLS fast reroute, enabling sub 50millisecond reroute to maintain real-time traffic during a node or link failure

2. Carrier-Class Reliability for the EnterpriseFully Redundant Hardware and

Comprehensive Soware Resiliency

Carrier-class reliability means that data, services, applications, and resources are

available 24x7. Network hardware and software need to work together to address every

potential cause of downtime in sub-seconds. Juniper Networks provides the following

software and hardware features to ensure carrier-class reliability:

Software features provide the ability to:

- Upgrade Junos OS releases with no disruption of the control plane and with minimal

traffic loss

- Forward traffic even when router experiences a failure condition

- Recover from failures quickly

- Detect failures in connectivity rapidly and redirect traffic on other links

Fully redundant hardware (cooling, power supplies, switch fabric, and Routing Engines),

achieved by implementing separate data and control planes

3. Improved User Experience and Application PerformanceHighly Customizable,

Comprehensive, Hardware-Based QoS Features

Todays networks must provide predictable and measurable services due to increased

media rich traffic and delay sensitive content. QoS requires managing several metrics such

as delay, delay variation (jitter), bandwidth, and packet loss parameters on a network

reliably (Over 75% of those surveyed reported service interruption and business impact).

To easily control these metrics, Junipers high-performance routers offer a rich set of QoS

featuresclassification, rewrite/marking, policing, and scheduling that can be easily and

consistently configured across routing devices.

needs

Table 1 summarizes key enterprise QoS requirements and the Juniper features that

address them. We examine these in greater detail below.

Enterprises frequently change QoS policies, which must be propagated to designated

routers and validated to accommodate rollout of new applications. This can be quickly

accomplished using sophisticated Junos OS commit scripts. For instance, some

enterprises roll out business applications or configure them every week, and these

require a corresponding change in QoS policies.

To guarantee application performance for delay sensitive and business critical

applications such as Oracle Financials, enterprises seek application-level classification

and control. Juniper facilitates this optimal application performance by providing

powerful granular firewall filters that are easier to configure and more flexible than

access control lists (ACLs).

Enterprises must monitor application data continuously to understand performance

of business critical applications, and to make proactive policy changes. To facilitate

this application-level monitoring, Juniper provides enterprises with metrics such as

firewall counters and J-Flow statistics, enabling enterprise IT to monitor application

performance history and easily make QoS policy changes for other applications.

Juniper offers line-rate performance for all QoS features, and can scale to match

any business need because all QoS features are implemented natively in the ASICs.

Junipers routing products offer a standard eight hardware queues per port, with an

option to increase to thousands of queues, if desired.

Ultra Low Latency Multicast and Unicast for Application Performance

Increased level of media rich traffic has raised the importance of optimized content

delivery. In addition, financial services, news services, and stock exchanges have high

touch content that requires low latency, a high level of resiliency, segmentation, and

privacy. Although native IP multicast can achieve these broadcast requirements, it lacks

the segmentation and privacy offered by combining multicast virtual private network

(MVPN) services and a point to multipoint (P2MP) delivery mechanism.

Juniper Networks is a leader in P2MP MPLS for optimal traffic replication. Junipers

hardware-based multicast allows for the highest network performance without

compromising application performance.

4. Reduced Network ComplexitySingle Operating System with a Single ArchitectureJunos OS gives organizations the ability to create a simple, predictable, and reliable

network design using one operating system, one architecture and one release train.

Junos OS integrates routing, switching, and security, and provides significant operational

savings by providing a flexible platform that can adapt to changing needs, as well as one

release train that enables a stable delivery of functionality. In a recent study, 52% indicate

multiple OS versions adversely impact their operational efficiency .

The figure to the right presents an independent study, conducted by Lake Partners, that

quantifies the time savings Junipers customers experience using Junos OS across a

number of common network operational tasks.

According to this study, an infrastructure of any size running Junos OS can save up to 25%

on operational costs. Since the IT department of a typical enterprise spends a significant

percentage of its budget to maintain and enhance basic IT services, any savings in

operational costs can be considerable.

The study also cites a 29% reduction in adding infrastructure with Junos OS, and

attributes this reduction to flexibility in the operating system. Flexibility is measured as

interoperability with existing infrastructure, modularity that allows network expansion,

support for multiple IP protocols that enables less complicated network growth, and

operating system consistency that facilitates planning.

Further, the study indicates that Junos OS reduces complexity by minimizing the number

and size of upgrades, and providing advanced monitoring tools that simplify and allow for

granular monitoring of network hardware.

The 54% reduction in troubleshooting time is a result of a modular architecture that

localizes failures through separation of control and forwarding planes guarantees

resiliency through graceful restart, and validates configurations.

Collapsed Architecture for the Data Center

The typical data center architecture has three tiers: access, aggregation, and core. The three-

tier architecture requires a large number of devices to deploy and manage, requiring large

capital investment, more rack space, increased power requirements, and increased latency.

Figure 3 shows a legacy design to the left marked by three tiers (core, aggregation, and

access), while the right shows a data center network that has only two tiers (core and

access). The figure to the right also shows that the collapsed network design has replaced

devices in the core and aggregation tier with larger capacity routers.

Figure 3: Comparison between three-tier and two-tier data center designs

Gartner Research estimates that the two-tier design provides approximate savings of

28% of the capital cost of the network. Their research predicts similar savings in power

and maintenance costs .

Juniper enables you to build a highly virtualized and secure data center network that

effectively collapses the aggregation and core into two simplified tiers. This collapse

is achieved by a high level of scalability of Juniper routers that aggregate several high

capacity uplinks from the access tier. The Juniper routers complement this scalability with

high performance and reliability that are critical for low latency and a fail-safe data center

core. In short, the collapsed core:

Simplifies network architecture by reducing the number of devices

Reduces latency

Reduces space, power, and cooling requirements

Simplifies management and support

5. Increased Operational Efficiency and SustainabilityOptimized Power, Cooling,

and Space

Energy has become a nontrivial OpEx item, as electricity costs have risen 88% in the

U.S. (U.S. EIA official Government statistics). For the past decade, IT has rapidly added

hardware to accommodate business growth, and many data centers are now stretched

to capacity in terms of power, cooling, and floor space. By refreshing the data center

infrastructure with higher performing, smaller footprint, and more power-conscious

routers, you can deliver additional capability and scalability within the same energy and

space footprint. Juniper Networks solutions significantly reduce network complexity and

lower the total cost of ownership by eliminating network tiers and devices, thus reducingspace, power, and cooling requirements.

A data center configuration that has 1,640 servers that are connected to the access

switches with dual GbE line-rate links. The access switches are connected to the core

through a 10GbE uplink. The core routers support several 10GbE links. The list price for

a fully deployed configuration of switches and routers is 18% lower for Juniper devices.

This CapEx reduction is the result of a collapsed core, which stems from a highly scalable

platform that can support many 10GbE uplinks and hence reduce the number of devices

needed in the core. The smaller number of devices also results in 67% reduction in rack

space and a 43% reduction in power relative to competition.

Solution Planning, Implementation, andDeployment (Sample Scenarios)

The high-performance network design calls for innovative solutions. Figure 4 depicts some

sample deployment scenarios that apply advanced routing.

Data center transport network

The private MPLS cloud connecting two or more enterprise data centers gives the

enterprise greater control over the network. The enterprise gains flexibility to manage

its competitive advantage efficiently with low latency and reliability, while running

applications on a cost-effective shared infrastructure.

The Data Center Transport Network figure shows the logical connectivity of the twodata centers. The different colored lines show that each application is allowed to

operate as if it had a private network, while maintaining QoS and latency requirements.

In case of a primary path failure (either of the blue or green lines), the critical

application is protected with a secondary/standby link (red line), with the same QoS

guarantees and predictable latency as SONET.

Data replication between data centers for increased resiliency

Many enterprises maintain colocation data centers and must migrate critical data

between them. These enterprises are looking for ways to avoid huge CapEx associated

with dedicated links, and OpEx to support migration requirements.

The data replication between data centers, shown in Figure 4, depicts virtual machine

migration from Data Center 1 to Data Center 2. This migration requires the two data

centers to be on the same Layer 2 network. By using a virtual private LAN service (VPLS)

for live migration, the enterprise no longer needs to deploy dedicated links between the

two data centers, thereby reducing capital and operating expense.

Network-wide virtualization with MPLS reducing the number of firewalls and filters in

the network

One physical network with several virtual networks allows privacy and control across

lines of business and applications. This optimal utilization of network resources

eliminates the need to have many firewalls and filters in routers throughout the network

to maintain privacy and security, reducing CapEx and OpEx.

The Network-wide Virtualization figure depicts multiple security silos maintained

between different physical locations (indicated by red, orange, and blue colored rings).

The L3VPNs provide virtual connections between silos of the same type (represented

by the same color). This design provides a simple alternative to distributed firewall and

dedicated connections between silos, significantly reducing cost and increasing the

flexibility of the network.

Regulatory compliance

Enterprises are exposed to many regulations, and they need a simple and cost-effective

solution that can provide an increased level of compliance. Junipers advanced routing

solutions provide technology for separation of not only transport but also routing

resources for increased compliance.

Figure 4 shows regulatory compliance in a power utility. The SCADA control system

traffic is separated from other traffic using MPLS without deploying physically separate

network links.
