3	KEY SOLUTION

Key Solution

D-Link Business Solution provides end-to-end network solution to achieve secure, reliable, easy to manage and high performance network for small, medium to large enterprises.

Over the past few years, enterprise access network has seen one of the fastest areas of growth. As technology evolves and user demand increases, enterprise access network is fast turning from a 'traditional’ data network to a more complex network with integrated data, voice and multimedia services. D-Link, in meeting the needs of enterprises to have more productive business processes, is therefore providing the following solutions for their access network:

•Wired/Wireless Connectivity Solution

D-Link provides wired and wireless solutions for access network infrastructure as the foundation for data communication and other IP-based services in the enterprise network. Core functionalities of these solutions include consistent wireless connectivity, comprehensive network control and secure user authentication. With these solutions, businesses and organizations will be able to have greater flexibility and investment protection through scalable network expansion for future technologies through Gigabit connectivity, such as the 10-Gigabit fibre link connection.

D-Link offers a Unified Wired/Wireless Switching solution which consists of D-Link access point and unified switch. This solution offers premium wireless connectivity options with flexible and easy-to-deploy central management system.

D-Link's unified switch is the managing device for thin access point. It provides centralized AP management and features L2/L3 roaming, automatic wireless channel assignment,and automatic power output adjustment. It offers Wireless Intrusion Detection System (WIDS) which empowers network administrators to detect rogue access points and rogue client. On the wired side, D-Link's unified switch utilized Dynamic ARP Inspection (DAI) and DHCP Snooping to ensure maximum security.

D-Link's unified access points provide features such as Power-over-Ethernet (PoE), choices of operating modes, user authentication, and wireless security. Its high speed dual band wireless IEEE802.11n standard offers Multiple In Multiple Out (MIMO) and wider bandwidth channels that increases the physical transfer rates.

•Unified IP Surveillance Solution

D-Link provides a complete IP Surveillance solution which consists of network cameras, video management

software (VMS), storage and Power-over-Ethernet (PoE) switches for network connectivity.

D-Link has a wide range of network cameras and network video recorders (NVR) for this solution. D-Link network cameras consist of fixed, pan-tilt-zoom (PTZ), fixed dome, and PTZ dome cameras with capability for indoor/outdoor, day/night usage. D-Link network cameras support megapixel resolution, 2-way audio, wired or wireless connection, PoE, choices of video format, digital and optical zoom. D-Link network cameras and NVR, together with D-ViewCam software, offers functionalities such as video recording, live viewing, playback, and event management.

D-Link IP Storage Area Network (SAN) arrays provide a reliable network data storage solution using powerful System-on-a-Chip (SoC) design to handle over 80,000 I/ Os per second and support terabytes of raw capacity using multiple 1TB hard drives. It can also be used as a backup and recovery device in the network. Large amount of videos and images captured from the network cameras can be stored in such storage devices securely.

D-Link Power-over-Ethernet (PoE) switches are equipped to inject up to 15.4 watts of power per port to network cameras. This eliminates the need to place the cameras within close proximity to a power outlet and minimizes cable clutter.

•Data/Video/Audio Triple Play Application Solution D-Link Web Smart III switches are ideal for deployment in a Voice over IP (VoIP) environment. They support Auto Voice VLAN and Differentiated Services Code Point (DSCP) Quality of Service (QoS) for VoIP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and enhance the VoIP service. This feature can guarantee the quality and security of VoIP traffic.

Aggregation Network

Aggregation network is where each connection from the access network is gathered and terminated. Enterprise network needs reliable redundant, and high performance devices to perform the necessary traffic policing and intermediate routing.D-Link therefore offers a robust solution for the aggregation network with its Layer-3 managed switch and Layer-3 chassis switch. With these devices, D-Link provides fundamental functions for enterprise aggregation network, which include:

DES-7200 specifications

The D-Link DES-7200 is a versatile, high-performance Ethernet switch designed for enterprise networks that require efficient data management and enhanced connectivity. This switch is manufactured to meet the demands of modern networking environments, offering a combination of scalability, reliability, and advanced features.

One of the key features of the DES-7200 is its support for 10/100/1000 Mbps Ethernet speeds, allowing it to easily handle high-bandwidth applications and large-scale data traffic. Its switching capacity, which can support a substantial number of simultaneous connections, ensures that the switch can keep up with the increasing demands of users and devices within a network.

The DES-7200 incorporates advanced Layer 2 and Layer 3 switching capabilities, making it suitable for a wide range of networking scenarios. This includes support for Virtual LANs (VLANs) which allow network administrators to segment networks for improved performance and security. The switch supports up to 4,096 VLANs, enabling efficient traffic management and isolation of sensitive data.

Another notable feature of the DES-7200 is its robust security protocols. It includes IEEE 802.1X port-based authentication, ensuring that only authorized users can access the network. Additionally, it supports Access Control Lists (ACLs) and Denial of Service (DoS) attack prevention measures, further enhancing network security.

D-Link has also integrated quality of service (QoS) functionality into the DES-7200, allowing for better handling of voice, video, and mission-critical data applications. With the ability to prioritize traffic, administrators can ensure a seamless and uninterrupted user experience, minimizing latency and congestion in busy network environments.

The DES-7200 features a user-friendly web-based interface for easy management and monitoring of the switch. This interface allows network administrators to configure settings, monitor performance, and troubleshoot issues quickly and efficiently.

Scalability is another significant characteristic of the D-Link DES-7200. It offers stacking capabilities, which means multiple switches can be managed as a single unit, simplifying network management and expanding network capacity without requiring excessive configuration.

Overall, the D-Link DES-7200 is a reliable choice for organizations looking to enhance their network infrastructure. With its combination of speed, security, and management capabilities, it stands as a robust solution for both small and large-scale enterprise networks.
