Mobile Core Networks
Introduction
A converged backbone provides a lower cost structure for legacy services while establishing a scalable core for new high speed offerings. As mobile carriers migrate to shared infrastructure, an IP/MPLS mobile packet backbone network enables assured service delivery for a diverse mix of offerings.
For years, Juniper Networks has been helping service providers evolve to a secure, converged IP infrastructure by providing industry-leading routing and security equipment, and by working closely with strategic partners to integrate our products into end-to-end solutions. These solutions are designed to address all of the key challenges faced by mobile operators in their migration from circuit-switched technologies--from the introduction of mobile softswitching through the deployment of IP transport and the evolution to IMS-FMC networks based on 3GPP and ETSI/TISPAN architectures.
Juniper Networks' packet core network solutions for mobile carriers use MPLS as a method of controlling traffic flows and integrating the transport of ATM and Frame Relay traffic into a multi-service mobile packet backbone while maintaining the quality associated with ATM and Frame Relay connectivity.
Description
Juniper Networks core router solutions form high capacity multiservice IP/MPLS backbones for converged provider networks around the world. With over 100 T-series customers worldwide and over 1,000 units deployed, Juniper Networks is a leader in next generation core routing deployments.
Our T-series routers deliver the unique combination of advanced routing features, best-in-class IP/MPLS capabilities, as well as unmatched reliability and scale. The T-series leverages JUNOS, the industry's only operating system that combines proven reliability with a development cycle that ensures continuous, non-disruptive feature and functionality enhancements.
Multi-service Core
Juniper Networks T-series routers provide a rich set of features supporting differentiated service classes for IPv4, IPv6, and MPLS traffic. Keeping flows separate enables support of diverse applications with different performance requirements and simplifies QoS to enable traffic prioritization.
Juniper Networks is active in IETF, the IPsphere Forum, and other standards groups. Our Provider Infranets offer a blueprint for helping service providers execute on the IPsphere Forum framework for integrating intelligence into service offerings and extending it across boundaries.
T-series routers enable the entire gamut of services in the mobile core, including voice, video, data, gaming, and the support of SLA-guaranteed service offerings for enterprises. The variety of MPLS core solutions available on Juniper routers is second to none. For instance, in a triple play network our support of Point-to-MultiPoint Label Switched Paths (P2MP LSPs) presents an ideal solution for delivering video. P2MP LSPs provide video traffic with bandwidth reservation, traffic engineering, and fast failover mechanisms not found in multicast protocols such as PIM or IGMP.
High Availability Architecture
The rigorous uptime requirements of converged carrier networks align with the diverse transport networks that precede them. Juniper Networks core IP solutions provide robust, scalable routing protocol implementations designed to converge quickly. MPLS provides failover mechanisms to redirect traffic within 50 ms for applications such as broadcast video. Key reliability features of the Juniper Networks platforms include:
- Nonstop Forwarding (NSF)
- Graceful Restart (GR)
- In-Service Software Upgrade (ISSU)
- Bidirectional Forward Detection (BFD)
- Traffic Engineering (TE) With Fast Reroute (FRR)
Scalability
JUNOS service deployments are proven to scale - across core, edge and access - with one operating system. To meet rising traffic demands, the TX matrix provides an evolutionary upgrade path to multi-terabit speeds. The Juniper Networks T640 and the TX Matrix protect customer investments with minimal or no disruption to core services during backbone upgrades. Other core routing vendors continue to offer upgrade paths with far higher CAPEX and production facility upgrades, while Juniper Networks provides clear investment protection that avoids the pain of forklift economics.
