DPX19000 Cloud Business Core

The DPX19000 Series is designed with a cutting-edge CLOS switching architecture, separated control plane and forwarding plane, and relatively independent master control engine and switch boards. In this way, it helps greatly improve device reliability while laying a foundation for future bandwidth upgrades.

Combing switching routing and network security, the DPX19000 Series becomes the first to realize the deep integration of layers 2 ~ 7. All service modules in a single device can be managed based on a single IP, making it simple to establish complex networking.

DPX19000 Series is highly scalable. It supports deep service functions such as application firewall and IPS, providing powerful security protection for network core. The hot elastic service expansion technology can made dynamic adjustments to service modules without restarting the device, enabling plug-and-play on-demand deployment of services.

It can provide single routing boards of million class; the connection boards support up to 24GB cache at a large caching rate of 200ms; when used with distributed ingress cache mechanism, it can meet the needs of large data centers with high burst traffic.

The DPX19000 Series adopts the industry's leading non-blocking hardware cluster system. Through cluster switching boards and VSM cluster matrix, it enables non-blocking switching in strict sense without occupying any business ports. Networking through 1 + 1 back-to-back interconnection or N + M interconnection is allowed.

Combing Combing switching, network security and application delivery, the DPX19000 Series becomes the first to realize the deep integration of layers 2 ~ 7. All service modules in a single device can be managed based on a single IP, making it simple to establish complex networking.

DPX19000 Series is highly scalable by supporting application firewall, IPS and other service slots.

The hot elastic service expansion technology can made dynamic adjustments to service modules without restarting the device, enabling plug-and-play on-demand deployment of services.

With strong network adaptability, it offers full support of QoS, IPv4/IPv6 routing, MPLS VPN and other network services.

Relying on VSM and OVC technologies independently developed by DPtech, the DPX19000 Series converts multiple similar service modules in a Cloud data center into a flexible scheduling resource pool, thus enabling a granular management of business platform resources and improving the utilization of resources. Automatic network management and operation solutions are enabled by UMC platform, and SDAN (Software Defined Application Network) by APP Flow or third-party interfaces.

Based on the innovative “service chain” concept, the DPX19000 Series is able to provide refined definition to data streams according to portfolio policies, customize data flow directions among various service modules, remove limitations of traffic scheduling between different service modules, and realize flexible scheduling at the business layer.

The DPX19000 Series supports mainstream Overlay standards such as VXLAN to address the issue of multi-tenancy. It offers a flexible virtual machine migration solution so as to meet users’ needs for large-scale server deployment and cross-domain connectivity in cloud computing environments. It is compatible with Openflow1.3 protocol, and offers multiple controllers and multi-level flow tables. It can serve as Openflow-hybrid to allow Openflow operations and standard Ethernet switching simultaneously.

Fully redundant hardware architecture DPX19000 Series supports 1+1 redundancy of master control board.N+1 redundancy of switching board,1+1 redundancy of fan module, N+M redundancy of power supply module. It supports uninterrupted restart, hot fixes, separated data/control/monitoring planes and other technologies, ensuring 99.999% carrier-grade reliability. It supports BFD, OAM and other fast fault detection technologies, and provides a series of device-level and network-level fault detection methods.

In response to an orthogonal architecture of service boards and switching boards, the DPX19000 Series is equipped with multiple innovative cooling technologies such as a dual air duct design, increasing heat radiation efficiency by 30%.
It is capable of performing temperature detection on key components such as service boards and switching boards. Based on the temperature and configuration of each component, it can realize intelligent fan speed regulation, and reduce power consumption and environmental noise. It improves energy efficiency with a power consumption of less than 6,000W, promoting the construction of a green network.
