The low-end of the new MX line is the MX5, a 20Gbps router that features 20 Gigabit Ethernet SFP interfaces and a variety of WAN interfaces: four to eight OC-3s, two to eight OC-12s, one to four OC-48s and eight DS-3s.
Next up is the MX10, a 40Gbps router with two slots for LAN interface modules undefined the same 20 Gigabit Ethernet card as the MX5, and a dual 10G Ethernet CFO card. It also supports the same WAN interfaces as the MX5.
The MX40 is a 60Gbps router that carries the 20 Gigabit Ethernet and dual-port 10G cards, to go along with the two 10G Ethernet ports already integrated into the device. It, too, supports the same WAN interfaces as the MX5 and MX10.
The new routers are based on the 80Gbps MX80, which Juniper began shipping last year. The MX80 forwards 55 million packets/sec, and houses modules with 20 ports of 10/100/1000Mbps Ethernet SFP, two 10G XFP Ethernets and 40 ports of 10/100/1000Mbps Ethernet with TX interfaces.
Juniper's new MX routers will go up against Cisco's ASR 1000 line, which was launched almost three years ago. Cisco's ASR routers scale from 2.5Gbps for the ASR 1002 to 360Gbps for the ASR 1013. WAN and LAN interface options include two and four-port channelised and clear channel T-3/E-3, four-port serial interface, eight-port channelised T-1/E-1, four- and eight-port 10/100 Ethernet, two, five, eight and 10-port Gigabit Ethernet, one-port 10 Gigabit Ethernet, two and four-port OC-3 packet over SONET (PoS) and one-port OC-12 PoS.
