![]() Cisco Systems has two boxes selling into this space: the 10000 series, considered Cisco's primary B-RAS entry, and the 7600 line of edge routers (of which the 7613 is the largest), which include some B-RAS capabilities. The E320 was designed with video in mind, adding the Quality of service (QOS) and high availability that carriers want for IPTV, as well as a huge increase in density. The box supports a 100 Gbit/s or a 320 Gbit/s switch fabric and hosts up to 12 line modules that support OC3/STM1 through OC48c/STM16 and 10 Gigabit Ethernet interfaces with the ability to support 96,000 subscribers. The Juniper E320 router is a high-performance router used primarily for large points of presence (PoPs). The E120 has a 120 Gbit/s switch fabric and hosts up to six line modules that support OC3/STM1 through OC48c/STM16 and 10 Gigabit Ethernet rates. The Juniper E120 router is a high-performance router used primarily for small to medium-sized points of presence (PoPs) and central offices. All E-series platforms use a single version of the JUNOSe operating system, and support a full suite of Internet routing protocols, including BGP-4, IS-IS, OSPF, and RIP. The specific models include the high-capacity E320 BSR and ERX-1440 platforms, the mid-range ERX-1410 platform, compact ERX-710 and ERX-705 platforms, and the highly compact ERX-310. The Juniper E-series includes six different models that are designed to address the variety of Service Provider requirements. ![]()
