Juniper M320 DC Base Unit – includes Control Board, 4 Switch Interconnect Boards, 1 Routing engine, and 4 DC Power Entry Modules *SEE NOTES Juniper Networks M-series Multiservice Edge platforms are deployed in the world's largest networks delivering advanced IP/MPLS services at scale, enabling service providers to reduce costs through network consolidation while simultaneously generating new revenues. Constructed with a clean separation between control plane, forwarding plane, and services plane, M-series routers support multiple services over any type of access connection without compromise on a single platform - maximizing revenue and minimizing operational and capital costs. These services include a broad array of VPNs, network-based security, real-time voice and video, bandwidth on demand, rich multicast of premium content, IPv6 services, granular accounting and much more. This service portfolio continues to grow with every release of JUNOS software, leveraging the tremendous flexibility and performance headroom of the service-built architecture.
