2-1-3-3. Switch Cascading in Topology

￿

￿￿Takes the Delay Time into Account

Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.3 series specification of Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.

Table 2-2

Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this will not be applied. You may use the TP-Fiber module to extend the TP node distance over fiber optic and provide the long haul connection.

￿￿Typical Network Topology in Deployment

A hierarchical network with minimum levels of switch may reduce the timing delay between server and client station. Basically, with this approach, it will minimize the number of switches in any one path; will lower the possibility of network loop and will improve network efficiency. If more than two switches are connected in the same network, select one switch as Level 1 switch and connect all other switches to it at Level 2. Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN or other special requirements are applied.

KGS-2416 specifications

KTI Networks KGS-2416 is a sophisticated Ethernet switch designed to meet the demands of modern networking environments. This device is particularly ideal for enterprises requiring robust performance for an expanding network infrastructure. With 24 10/100/1000Base-T ports and 2 gigabit SFP (Small Form-factor Pluggable) uplink ports, the KGS-2416 provides ample connectivity options suitable for a variety of applications, including servers, workstations, and other network devices.

One of the standout features of the KGS-2416 is its support for Layer 2 switching, which enhances data traffic management by enabling the configuration of VLANs (Virtual Local Area Networks). This capability allows network administrators to segment traffic and improve overall network performance and security. The switch supports IEEE 802.1Q VLAN tagging, allowing for up to 4096 VLANs to be configured, thus ensuring flexible network design and management.

Additionally, the KGS-2416 supports advanced traffic management features such as Quality of Service (QoS). This technology prioritizes critical network traffic, ensuring smooth and uninterrupted service for voice, video, and data applications. With support for multiple QoS standards, administrators can tailor the performance of their networks based on their specific needs.

Power over Ethernet (PoE) capability is another significant feature of the KGS-2416, allowing users to deliver both data and power over a single Ethernet cable to powered devices. This capability simplifies wiring and reduces the need for additional power supplies, making it an ideal solution for deploying IP cameras, wireless access points, and VoIP phones.

The switch is designed with an intuitive user interface that makes configuration and management hassle-free. It can be managed through both web-based GUI and command-line interface (CLI), providing flexibility for various administrative preferences. Moreover, the device supports SNMP (Simple Network Management Protocol), allowing for seamless integration into existing network management systems.

In terms of reliability, the KGS-2416 boasts features like redundant power supply options and a fanless design for silent operation. This makes it a reliable choice for environments where noise and downtime must be minimized. Overall, the KTI Networks KGS-2416 is an excellent choice for organizations looking for a feature-rich, reliable, and efficient Ethernet switch to power their networking needs.
