DCRS-9800 Series Cloud Stone Core Layer Routing Switch

Performance and Scalability
DCRS-9816 supports up to max 320*10G ports or 384 Gigabit ports, providing flexibility and high port density.
10G modules support max 20 ports for downlink to distribution layer switches or access switches directly, aggregating them to the core layer, and preventing port bottlenecks in Gigabit switches. Furthermore, the optional 10Gigabit Ethernet SFP+ transceivers can be chosen for different distance fiber uplinks.
Backup Master ensures the availability of a master controller for network control at any time.
Firmware & configuration are automatically upgraded from master to slave units for management simplicity.
Intensive protocol support is included for MPLS, L2/L3 MPLS-VPN supported by software upgrade to ensuring future investment protection.

OpenFlow
Supports OpenFlow1.2 standard protocol. OpenFlow network is increasingly becoming a trend as the core protocol of SDN network. It makes the network easier programming OpenFlow brings the high performance to datacenter users via self-defined network. With OpenFlow, this product is ideal to build SDN test-bed for research institutes and SDN Experimental Bureau for large ISP and operator.
support open controller Opendaylight, Floodlight, Ryu, Pox, etc.

Continuous Availability
IEEE 802.1w Rapid Spanning Tree Protocol provides a loop free network and redundant links to the core network with rapid convergence.
IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing Layer 2 load sharing on redundant links.
IEEE 3ad Link Aggregation Control Protocol (LACP) increases bandwidth by automatically aggregating several physical links together as a logical trunk and providing load balance and fault tolerance for uplink connections.
IGMP snooping prevents flooding of IP multicast traffic, and limits bandwidth intensive video traffic only to the subscribers.

L3 Features
The DCRS-9800 series delivers high-performance hardware based IP routing.
RIP, OSPF and BGP provide dynamic routing by exchanging routing information with other Layer 3 switches or routers within same domain and different domain.
DVMRP, PIM-SM/DM Multicast Routing Protocols send IP multicast traffic from one subnet to another.
VRRP prevents your system from failing by dynamically backing up multiple L3 switches for routing.
Support OSPF and BGP graceful restart to protect network stability.

Strong Multicast
The DCRS-9800 support abundant multicast features. The product support rich L2 multicast features such as IGMPv1/v2/v3 and snooping and L3 multicast protocols such as DVMRP, PIM-DM, PIM-SM and PIM-SSM. As the rich application experience, the product support Multicast VLAN Register and Multicast Receive Control and Illegal Multicast Source Detection

MRPP (Multi-layer Ring Protection Protocol), is a link layer protocol applied on Ethernet loop protection which reduces network convergence time to 50ms.

Comprehensive QoS
8 egress queues per port enable differentiated management of up to 8 traffic types.
Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as voice and video.
Bidirectional rate limiting, per port or traffic class, preserves network bandwidth and allows full control of network resources.

Enhanced Security
IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network.
MAC based authentication can provide client-free security access and help customer deployed security rapidly.
Access Control Lists (ACL) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers.
SSL, Web Management Encryption, RADIUS and TACACS+ authentication, authorization and accounting protect data communication and ensure data privacy.

Simple Management
Industry standard Command Line Interface (CLI) via console port or Telnet can be used for switch management.
Embedded user friendly web interface helps users quickly and simply configure switches.
Backup and restore Firmware and configuration files via TFTP.

Abundant IPv6 Support
The DCRS-9800 series switch supports IPv6 routing in hardware for maximum performance. As more network devices growing and the need for larger addressing and higher security become critical, the DCRS-9800 series switch will be a right product to meet the requirement. The DCRS-9800 passed IPv6 form Phase II certificate is the best proof of the application.

Environment protect
The currently network construct must consider energy sources and help end-customer save power. With many years hardware design experience, The DCRS-9800 series control power source in every detail such as power module, fan module and system power control.
