Routers that Run Junos

By Walter J. Goralski, Cathy Gadecki, and Michael Bushong from JUNOS OS For Dummies, 2nd Edition

Juniper offers routing platforms running Junos for branch and regional offices, corporate sites and data centers, along with the metro, edge, and core sites of service provider networks. The decision of what platform to use depends on where you’re deploying it, and thereby, the required throughput and feature set.

Juniper Networks routing platforms meet a full range of networking needs from small branch offices to the largest TeraPop sites in the world. The routing platforms support IPv4 and IPv6 addressing, all standard routing protocols, routing policy, multicast (traffic from one point that must go to many points), and MPLS VPNs.

Additionally, the platforms offer stateful firewall, many types of tunneling and other security features, classification and accounting of traffic, and other services that require rich packet processing along with many High Availability features.

Routing Series	General Usage Tips
J Series	Branch and regional offices requiring routing, security, application optimization, voice capabilities, and a variety of WAN interfaces in a single remotely manageable platform
M Series	Network gateway points in large office, campus, and data center sites that require IP/MPLS capabilities with added security and networking services
MX Series	Ethernet LAN and data center aggregation, data center core, metro Ethernet aggregation and core, and Ethernet services edge networks requiring high capacity routing, high port density, and a rich set of security and networking services
T Series	Core backbones of high availability service provider networks, as well as the core routing of businesses, schools, and governments that require multi-Terabit throughput rates
