1.6 Juniper Networks Internet Backbone Routers Advantages
Features Benefits
Architecture
Highly Integrated ASIC forwarding
§ Fully sized and designed to perform lookups at a rate of 160 Mpps.
§ Scales well with large, complex forwarding tables.
§ Full utilization of expensive circuits.
§ Packet size does not affect forwarding performance.
§ Rock solid system stability.
§ Lower part count for high reliability.
Routing and forwarding performance cleanly
separated
§ Routing fluctuations and network instability do not impede packet
forwarding at full wire rate.
§ Rapid convergence.
§ Reliable and predictable performance for latency sensitive traffic,
such as voice over IP and streaming video multicasting.
Single-stage buffering
§ Eliminates head-of-line blocking.
§ Efficiently uses available interface bandwidth.
§ Optimal support for multicast traffic.
§ Reduces latency by requiring only one write to and one read from
shared memory.
Features are implemented in ASICs
§ Industry-leading performance with value-added services enabled
Redundant Switching and Forwarding Module
(SFM)
§ Increases system availability.
§ Ensures automatic failover to redundant SFM in case of failure.
Redundant Routing Engine and Miscellaneous
Control Subsystem (MCS)
§ Increases system availability.
§ Decreases mean time to repair (MTTR).
All components are hot swappable
§ Increases system serviceability and availability.
§ Decreases MTTR
JUNOS Internet software already deployed in the
largest and fastest growing networks
§ Proven performance and reliability.
Interfaces
Market-leading port density
§ Efficient use of POP rack space.
§ Future growth not limited by space.
Fine granularity of interchangeable interfaces
§ Flexibly deployed in multiple environments including core, peering,
high-speed access, and hosting.
§ Lowers the cost of entry configurations.
Environmental
Maximum chassis power of 2,600 watts with
redundant, load sharing DC power supplies
§ Efficiently uses power for economical deployment and operation.
Protection Mechanisms
MPLS Fast Reroute
§ Recovers from MPLS path failures for SDH and WDM connections.
Dual-router Automatic Protection Switching (APS)
1:1
§ Ensures rapid recovery from router-to-ADM circuit failures by
switching to a back-up fiber.
Virtual Router Redundancy Protocol (VRRP)
§ Exploits the inherent redundancy of routers on a Gigabit Ethernet
LAN.
