Tier Architectures

 

TWO-TIER ARCHITECTURE

TWO-TIER ARCHITECTURE IS SIMILAR TO BASIC CLIENT SERVER MODEL. THE APPLICATION AT THE CLIENT END DIRECTLY COMMUNICATION WITH THE DATABASE AT THE SERVER SIDE. THE APPLICATION ON THE CLIENT SIDE ESTABLISHED A CONNECTION WITH THE SERVER SIDE IN ORDER TO COMMUNICATE WITH DBMS.

AN ADVANTAGES OF THE TYPE IS THAT MAINTENANCE AND UNDERSTANDING IS EASIER COMPATIBLE WITH EXISTING SYSTEM HOWEVER THE MODEL GIVES POOR PERFORMANCE WITH THREE ARE A LARGE NUMBER OF USERS.





THREE-TIER ARCHITECTURE

IN THIS TYPE THERE IS ANOTHER LAYER BETWEEN THE CLIENT AND THE SERVER THE CLIENT DOES NOT DIRECTLY COMMUNICATE WITH THE SERVER INSTEAD IN INTERACTS WITH AN APPLICATION SERVER WHICH FURTHER COMMUNICATION WITH THE DATABASE SYSTEM AND THE QUERY PROCESSING AND TRANSACTION MANAGEMENT TAKE PLACE THE INTERMEDIATOR LAYER ACT AS A MEDIUM FOR EXCHANGE FOR PARTIALLY PROCESS DATA BETWEEN SERVER AND CLIENT THIS TYPE OF ARCHITECTURE IS USED IN CASE OF LARGE WEB APPLICATION.





SPIN-LEAF ARCHITECTURE

LEAF SWITCH

A LEAF SWITCH IS A TYPE OF SWITCH THAT IS USED IN A SPINE-LEAF NETWORK ARCHITECTURE. LEAF SWITCHES ARE RESPONSIBLE FOR CONNECTING SERVERS AND OTHER NETWORK DEVICES TO THE NETWORK. THEY ALSO PROVIDE LAYER 2 SWITCHING AND LAYER 3 ROUTING SERVICES.

IN A SPINE-LEAF NETWORK ARCHITECTURE, LEAF SWITCHES ARE CONNECTED TO SPINE SWITCHES IN A FULL-MESH TOPOLOGY. THIS MEANS THAT EACH LEAF SWITCH IS CONNECTED TO EVERY SPINE SWITCH. THIS DESIGN PROVIDES HIGH BANDWIDTH AND REDUNDANCY FOR TRAFFIC BETWEEN LEAF SWITCHES.

LEAF SWITCHES ARE TYPICALLY HIGH-PERFORMANCE SWITCHES WITH A LARGE NUMBER OF PORTS. THEY ALSO HAVE A WIDE RANGE OF FEATURES, SUCH AS SUPPORT FOR VIRTUALIZATION, SECURITY, AND QOS.

LEAF SWITCHES ARE A KEY COMPONENT OF SPINE-LEAF NETWORK ARCHITECTURES. THEY PROVIDE THE HIGH BANDWIDTH AND REDUNDANCY NEEDED TO SUPPORT MODERN DATA CENTERS. THEY ALSO OFFER A WIDE RANGE OF FEATURES THAT MAKE THEM IDEAL FOR ENTERPRISE NETWORKS.

SPIN SWITCH

A SPINE SWITCH IS A TYPE OF SWITCH THAT IS USED IN A SPINE-LEAF NETWORK ARCHITECTURE. SPINE SWITCHES ARE RESPONSIBLE FOR CONNECTING LEAF SWITCHES TOGETHER AND PROVIDING LAYER 3 ROUTING SERVICES.

IN A SPINE-LEAF NETWORK ARCHITECTURE, SPINE SWITCHES ARE CONNECTED TO EACH OTHER IN A FULL-MESH TOPOLOGY. THIS MEANS THAT EACH SPINE SWITCH IS CONNECTED TO EVERY OTHER SPINE SWITCH. THIS DESIGN PROVIDES HIGH BANDWIDTH AND REDUNDANCY FOR TRAFFIC BETWEEN SPINE SWITCHES.

SPINE SWITCHES ARE TYPICALLY HIGH-PERFORMANCE SWITCHES WITH A LARGE NUMBER OF PORTS. THEY ALSO HAVE A WIDE RANGE OF FEATURES, SUCH AS SUPPORT FOR VIRTUALIZATION, SECURITY, AND QOS.

CSST COURSE 1.0

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...
