Flexible Modular Design

The DGS-8000 series is available in two models: the DGS-8006 6-slot chassis with 6 open slots, and the DGS-8010 10-slot chassis with 10 open slots. Two open slots are reserved for redundant backup control modules and the other open slots can be fitted with user-selectable port modules. In addition to the open slots, there are 2 slots for redundant backup power supplies, and one slot for a replaceable fan module. This modular architecture allows modules to be gradually added to meet network growth, and modules to be easily swapped anytime to fit network requirement changes.

There are two different Control Module (CM) and I/O module series available for DGS-8000 chassis. Work with 8000-CM1, the Enterprise (E-series) line cards providing wired speed forwarding for enterprise / campus backbone. Work with 8000-CM2, the Data Center (D-series) line card provide up to 2.56TB switching capacity and high density 10G switching for data centers. 

Deployable as Core or Distribution Switch

Using a common set of modules for 10/100/1000BASE-T ports, PoE support, SFP, and 10-Gigabit uplinks, IT personnel can fit a DGS-8000 series switch with different port types and deploy it either as a core switch or an aggregation (i.e. distribution) switch. As a core switch, the DGS-8000 series provides numerous high-speed fiber backbones for a campus and central office network, while as an aggregation switch can provide high port density connections to workstations in an office environment, or to a subscriber’s CPE in a densely populated Ethernet metro area network. 

Distributed Architecture

To make use of this high-performance hardware, the DGS-8000 series utilise a distribution switching method which has each line card (the port module that directly connects to the network nodes) intelligently determine the switch path for each data packet. The switches synchronise the switching and routing information between the control cards and the line cards to map out the fastest data transfer path. With each line card capable of performing L2/3/4 on-board packet switching without reliance on the control cards, the DGS-8000 series switches can deliver very fast packet forwarding at almost zero-wait speed. 

High Port Densities

Port densities can reach 192 Gigabit / 10-Gigabit or 16 40-Gigabit ports per 6-slot chassis, or 384 Gigabit / 10-Gigabit or 32 40-Gigabit ports per 10-slot chassis. All port modules are hot swappable, and can be used in either chassis type without the need to change hardware or software settings.  

Application Convergence

The DGS-8000 series combines high-speed hardware with software functions like prioritised traffic QoS and multicast routing to deliver performance suitable for real-time applications such as Internet telephony, streaming multimedia, and TV. In addition, these switches offer Power over Ethernet (PoE) solutions to provide both power and network connectivity to PoE- capable devices such as IP phones and wireless AP, and are ideal for large-scale enterprise edge deployment. An example of this application convergence would be VoIP for mobile users via wireless access points connected through DGS-8000 series switches. 

Comprehensive IPv6 Support

The DGS-8000 series provides complete support for IPv6 to accommodate the potential huge increase in number of users and geographical needs of the expanding Internet. It addresses the requirements of emerging applications such as Internet-enabled wireless devices, home and industrial appliances, Internet-connected transportation, integrated telephony services, sensor networks, distributed computing, and gaming. The use of globally unique IPv6 addresses simplifies the mechanisms used for reachability and end-to-end security for network devices that are crucial to the applications and services that are driving the demand for IP addresses. 

Enterprise-Wide Security

The DGS-8000 series provides not only network access security but also protection against virus and worm attacks. Access security is provided through comprehensive policy-based ACL, port security, address binding features, and Defeat IP Scan, while attacks hidden behind control protocols are thwarted to prevent the switch’s CPU from being overwhelmed with unnecessary tasks which can cause degradation to a network’s performance. The DGS-8000 series extends security to network management via such functions as SSH v2 and SNMP v3 with authentication and encryption of management traffic. 

MPLS Functions

The DGS-8000 series supports many advanced Multiprotocol Label Switching (MPLS) functions, including MPLS label management, LDP, MPLS L2/L3 VPN, and VPLS. Enabling enterprises and service providers to build next-generation intelligent networks that deliver a wide variety of advanced, value-added services over a single infrastructure. This solution can be integrated seamlessly over any existing infrastructure, such as IP, Frame Relay, ATM, or Ethernet. Subscribers with differing access links can be aggregated on an MPLS edge without changing their current environments, as MPLS is independent of access technologies.

QoS & Bandwidth Management

The DGS-8000 series supports numerous advanced traffic management options including flow-based bandwidth control and broadcast/multicast storm control. It provides egress traffic bandwidth control with minimum granularity of 64 Kbits. Combining Rate Limiting applicable to categories of subscriber CPE and access control-based accounting, the DGS-8000 series provides functions that are useful for carriers offering services to home users in a metropolitan Ethernet network. 

Comprehensive Management

To maximise management uptime, the DGS-8000 series provides optional dual redundant backup management agents in the same chassis. It offers a comprehensive set of management features to provide enterprise-wide visibility and control to network administrators for configuration, access and traffic monitoring and troubleshooting. These features are accessible through a CLI, Telnet, or SNMP console. RMON monitoring is supported, and complete debug, system, and alert information is provided.
