NMS

Network Management System. An interface that provides a method of managing a

system.

 

 

 

 

A network connection endpoint or a common junction for multiple network lines. Nodes

 

include:

Node

• Processors.

 

• Controllers.

 

• Workstations.

 

 

O

 

 

Object Identifier. Used by SNMP to identify managed objects. In the SNMP Manager/

OID

Agent network management paradigm, each managed object must have an OID to

 

identify it.

 

 

OSPF

Open Shortest Path First. A TCP/IP Interior Gateway protocol that calculates the lowest-

cost route, multipath routing, and load balancing.

 

 

 

P

 

Packet

Blocks of information for transmission in packet switched systems.

PDU

Protocol Data Unit. A data unit specified in a layer protocol consisting of protocol control

information and layer user data.

 

PING

Packet Internet Groper. Verifies if a specific IP address is available. A packet is sent to

another IP address and waits for a reply.

 

Policing

Determines if traffic levels are within a specified profile. Policing manages the maximum

traffic rate used to send or receive packets on an interface.

 

 

 

Port

Physical ports provide connecting components that allow microprocessors to

communicate with peripheral equipment.

 

 

 

Port Mirroring

Monitors and mirrors network traffic by forwarding copies of incoming and outgoing

packets from one port to a monitoring port.

 

 

Indicates port speed. Port speeds include:

Port Speed

• Ethernet 10 Mbps.

• Fast Ethernet 100Mbps.

 

 

• Gigabit Ethernet 1000 Mbps.

 

 

PPP

Point-to-Point Protocol. Enables connecting to the Internet over a serial link. PPP

establishes sessions between a PC and an ISP using the Link Control Protocol (LCP).

 

Privilege

An authorizations set that performs security-relevant functions, for example, user access

to a device.

 

Protocol

A set of rules that governs how devices exchange information across networks.

Protocol Stack

Layered set of protocols working together to provide networking functions.

Q

 

 

Quality of Service. QoS provides policies that contain sets of filters (rules). QoS allows

QoS

network managers to decide how and what network traffic is forwarded according to

 

priorities, application types, and source and destination addresses.

 

 

Query

Extracts information from a database and presents the information for use.

R

 

RADIUS

Remote Authentication Dial-In User Service. A method for authenticating system users,

and tracking connection time.

 

 

 

RDP

Remote Desktop Protocol. Allows a clients to communicate with the Terminal Server over

the network.

TL-SG3109, TL-SL3428, TL-SL3452 specifications

The TP-Link TL-SL3428 is a feature-rich Ethernet switch designed for small to medium-sized business environments. It is part of TP-Link’s JetStream series, which emphasizes reliability, performance, and robust management capabilities. Built with 28 10/100/1000 Mbps ports, the TL-SL3428 provides sufficient bandwidth to support a wide range of network applications.

One of the standout features of the TL-SL3428 is its support for Layer 2 management protocols. This allows for more granular control and optimized performance across network segments. The switch supports VLAN (Virtual Local Area Network) segmentation, which enhances network security and efficiency by isolating various types of traffic. This feature is particularly useful in larger organizations where different departments or teams may require separate network environments.

The TL-SL3428 also includes advanced QoS (Quality of Service) capabilities. This functionality prioritizes traffic based on predefined rules, which ensures that critical applications receive the necessary bandwidth to function optimally. With QoS implementation, users can experience minimized latency, leading to better performance in VoIP and video conferencing applications.

In terms of redundancy and reliability, the switch also supports Link Aggregation Control Protocol (LACP), enabling multiple connections to be combined for increased bandwidth and failover support. This feature significantly enhances network resilience, ensuring minimal downtime during failures.

Power over Ethernet (PoE) support is another important characteristic of the TL-SL3428. With PoE capabilities, this switch can deliver electrical power along with data over the same Ethernet cable, simplifying installation and reducing the need for additional wiring. This is especially advantageous for IP devices like cameras, access points, and VoIP phones.

Security features are abundant in the TL-SL3428 as well. It implements port security, storm control, and DHCP snooping, all of which contribute to a secure network infrastructure. The switch’s management capabilities can be accessed through a user-friendly web interface, making it easier for IT administrators to configure and monitor network activities.

Overall, the TP-Link TL-SL3428 is an exemplary choice for businesses looking to enhance their network performance with advanced management features, security protocols, and reliability. Its combination of speed, flexibility, and manageability make it a valuable tool for any growing organization.
