Non-Stop Routing (NSR), Non-Stop Bridging (NSB), Graceful Routing Engine Switchover (GRES), Graceful Restart (GR), and In-Service Software Upgrade (ISSU) Routing Here’s just a sample of what is available on the MX: High availability

In addition to the “oldies, but goodies,” is an entire feature set focused on Service Provider switching and broadband network gateway (BNG). The MX Series has a strong pedigree: although mechanically different, it leverages technology from both the M and T Series for chassis management, switching fabric, and the Routing Engine.įeatures that you have come to know and love on the M and T Series are certainly present on the MX Series, as it runs on the same image of Junos. It’s no easy task to create a platform that’s able to solve these new challenges. The “M” still refers to the multiple services heritage, while the “X” refers to the new switching capability and focus on 10G interfaces and beyond it’s also interesting to note that the Roman numeral for the number 10 is “X.” It is optimized for delivering high-density and high-speed Layer 2 and Layer 3 Ethernet services. The MX Series was introduced in 2007 to solve these new challenges. Ethernet enables the simplification in network operations, administration, and maintenance. Companies have challenging requirements to reduce operating costs and at the same time provide more services. It’s one of the most well understood and deployed networking technologies used today. Nearly all networking equipment connects via Ethernet. Large Enterprise companies are becoming more Service Provider-like and are offering IP services to departments and subsidiaries. Frame relay and ATM have been decimated, as customers are demanding high-speed Layer 2 and Layer 3 Ethernet-based services. The primary use case for the M Series was to allow Service Providers to deliver services based on IP while at the same time supporting legacy frame relay and ATM networks.įast-forward 10 years and the number of customers that Service Providers have to support has increased exponentially. As the product portfolio expanded, the “M” now refers to the multiple services available on the router, such as MPLS with a wide variety of VPNs. Originally, the model name M40 referred to its ability to process 40 million packets per second (Mpps). The M40 was also the first router to have a true separation of the control and data planes, and the M Series was born. Leveraging Application-Specific Integrated Circuits (ASICs), the M40 was able to outperform any other router architecture.

Back in 1998, Juniper Networks released its first router, the M40.
