CPU under attack. The router can’t be

managed.

Financial and operational service can't be protected.

The online video can’t be smoothly displayed.

Internet access is too slow. Traffic can not be monitored

With the access mode becoming more and more, the speed is faster and faster (MSTP 、 fiber 、 PON), the bandwidth requirement is growing rapidly.

With multi -services running , DRO router can achieve 100M wire-speed forwarding.

Nearly no interruption when using ACL 、 QOS 、 PBR 、 NAT.

Under 100M line， DRO router won’t be the bottleneck of network.

High performance ---In services

DEF－D-link Express Forwarding DEF achieve multi-service integration, Increase performance of ACL, PBR，NAT， FW，QOS

etc.

High performance --- D-link DEF fast forwarding

When ACL, PBR，NAT， FW，QOS is deployed, DEF achieves exact matching with the 1st packet, and the matching of following packets according to the flow table. No impact on performance between deploying 1 piece of ACL and 500 pieces of ACL!

Flow-based speeding mechanism

High performance --- D-link DEF fast forwarding

X-FLOW is the data processing mechanism of DEF.

Traffics with the same SIP, DIP, TCP/UDP port number, protocol number, are defined as a flow. DRO applied the flow table technology.

DROs can achieve different functions of switch and router by deploying the switching module.

Multi-service --- routing, switching all-in-one

Why All-in-one design: Greatly save the cost of TCO 。 Decrease the maintenance cost, Save installation space Save one machine’s power for “green world” 。

Multi-service --- distributed architecture

Advantage:• Modular design, based on the customer’s real need, easy to

be extended and flexible to use.• Distributed architecture switching module with own CPU and

OS, decrease the burden of CPU, promote the stability. • Switching module with separate OS, and D-link has nearly

million deployment of switches with high maturity OS.• All the switch functions are included.

• Flexible for remote areas to access.

• Serve as backup link for enterprise network.

Layer 7 applications can be deeply integrated into DRO router.

• How many applications? Network attack? Which is the key application? Where does the flow come from?

With IPFIX, network is transparent to you.

High availability4

The V-CPU technology of DRO router, can separate the CPU into two part, the management and data-forwarding.

No matter how large the attack and data flow is, the management will be always available.

High availability --- equipments can be managed in any time

Why V-CPU:The equipment can be managed at any time!!!

CPU

VCPU ： Virtual CPU technology ， CPU resources can be virtualized into two part: data forwarding and system management, the resources can be adjusted dynamically.

Data forwarding CPU ： specialized for data forwarding System management CPU ： control plane and management plane No matter how large the attack and data flow is, the management won’t be

interrupted
