INTRODUCTION

This chapter describes the features of the DGS-1224T and some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets.

Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and

DGS-1224T specifications

The D-Link DGS-1224T is a robust and versatile Ethernet switch designed for small to medium-sized businesses that require reliable network performance. With 24 10/100/1000 Mbps Ethernet ports, it provides high-speed connectivity and efficient data transfer rates across the network. This Layer 2 managed switch supports a range of advanced features and technologies that enhance its operational effectiveness and usability.

One of the standout features of the DGS-1224T is its web-based management interface, which allows for easy configuration and monitoring of the switch. This interface provides access to various settings, enabling network administrators to optimize performance according to their specific needs. The switch supports Virtual LANs (VLANs), which help to segregate network traffic for improved security and performance. By creating multiple VLANs, businesses can prioritize traffic and reduce congestion, ensuring that critical applications receive the bandwidth they need.

Additionally, the DGS-1224T includes Quality of Service (QoS) functionalities, which guarantee that voice and video applications maintain high quality through traffic prioritization. This is particularly important for businesses that rely on VoIP and video conferencing solutions, as it ensures minimal latency and jitter.

Power over Ethernet (PoE) support is another significant characteristic of the DGS-1224T. This feature enables the switch to deliver power to compatible devices, such as IP cameras and wireless access points, eliminating the need for separate power supplies and simplifying installation.

The switch also incorporates robust security features, including Access Control Lists (ACLs), which allow administrators to control which devices can access the network. Other security measures include storm control and DHCP snooping to prevent unauthorized access and potential attacks.

In terms of performance, the DGS-1224T supports up to 48 Gbps non-blocking switching capacity, which ensures that the switch can handle heavy traffic without bottlenecks. Its fanless design contributes to quieter operation and makes it suitable for noise-sensitive environments.

Overall, the D-Link DGS-1224T is an excellent choice for businesses looking for a reliable, feature-rich switching solution that can scale with their growing networking needs while ensuring high performance and security.
