Mobile Core Networks
Imtech Telecom Global and Juniper Networks have been working with service providers to evolve a secure, converged IP infrastructure. A converged backbone provides a lower cost structure for legacy services, whilst establishing a scalable core for new high speed offerings. As mobile carriers migrate to shared infrastructure, an IP/MPLS mobile packet backbone network ensures delivery of a diverse mix of services. Imtech’s solutions integrate industry-leading routing and security equipment into end-to-end solutions.
Imtech’s mobile core network solutions have been designed to address all of the key challenges faced by mobile operators in their migration from circuit-switched technologies; from the introduction of mobile soft switching through to the deployment of IP transport and the evolution to IMS-FMC networks based on 3GPP and ETSI/TISPAN architectures.
Imtech’s 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, whilst maintaining the quality associated with ATM and Frame Relay connectivity.
Imtech utilise Juniper’s leading next generation core routing products to form high capacity multi-service IP/MPLS backbones for converged provider networks around the world.
Juniper’s T-series routers deliver the unique combination of advanced routing features, best-in-class IP/MPLS capabilities and unmatched reliability and scale. The T-series run Junipers trusted JUNOS o/s, combining proven reliability with a development cycle that ensures continuous, non-disruptive feature and functionality enhancements.
Juniper Networks Multi-service Core routers
Juniper’s 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.
T-series routers enable the entire gamut of services in the mobile core, including voice, video, data, gaming and the support of SLA-guaranteed services for enterprises. For example, in a multiplay network support of the Point-to-MultiPoint Label Switched Paths (P2MP LSPs) provides an ideal solution for delivering video. P2MP LSPs supply 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. Imtech’s core IP solutions provide robust, scalable routing protocol implementations designed to converge quickly. MPLS provides failover mechanisms to redirect traffic within 50 milliseconds for applications such as broadcast video. Key reliability features of the Juniper’s platforms include:
- Non-stop Forwarding (NSF)
- Graceful Restart (GR)
- In-Service Software Upgrade (ISSU)
- Bidirectional Forward Detection (BFD)
- Traffic Engineering (TE) With Fast Reroute (FRR)
Scalability
Juniper’s all encompassing JUNOS operating system is proven to scale - across core, edge and access. With rising traffic demands, the TX matrix provides an evolutionary upgrade path to multi-terabit speeds. The T640 and the TX Matrix protect customer investments with minimal or no disruption to core services during backbone upgrades, ultimately reducing CAPEX costs.
