Multiple remote office or user connected to data center network and server for resource or information sharing. Multiple remote office connected to data center server via VPN. Multiple ISP connected each branch and give failover service and using routing protocol OSPF.

- 6. Components of Data Center Networks 6 ✔ Servers Servers are crucial in data center networks as the primary computing resources. They handle data processing, storage, and application execution in a data center environment. ✔ Storage Devices Storage devices are essential components in data center networks for storing and retrieving data. Common types of storage devices include hard disk drives (HDDs), solid-state drives (SSDs), and network-attached storage (NAS) devices. ✔ Storage Devices Storage devices are essential components in data center networks for storing and retrieving data. Common types of storage devices include hard disk drives (HDDs), solid-state drives (SSDs), and network-attached storage (NAS) devices. ✔ Switches Ethernet switches are commonly used in data centers to handle communication within the local area network (LAN). In contrast, Fibre Channel switches are utilized for storage area networks (SANs) to enable high-speed and reliable storage connectivity. ✔ Firewalls Firewalls monitor and control incoming and outgoing network traffic. ✔ Routers They use routing protocols such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF) to exchange information and make intelligent routing decisions. ✔ Load Balancer Load balancers play a crucial role in data center networks by distributing network traffic across multiple servers.
- 7. Data Center Equipment Cabinets 7 ✔ Structured Cabling ✔ Unstructured Cabling ✔ Minimize patching between cabinets and racks ✔ Intelligent patch panel apply in IoT Devices Figure-01: Data Center Network Caballing
- 8. Data Center Network Architecture 8 The ANSI/TIA-942 Data Center Infrastructure standard is an international standard developed through the Telecommunications Industry Association (TIA) to identify the requirements and guidelines for the design of data centers. ✔ Computer Room: Main servers ✔ Entrance Room: Data Center to external cabling ✔ Cross-Connect: Enables termination of cables ✔ Main Distribution Area (MDA): Main cross connect. Central Point of Structured Cabling. Core network devices ✔ Horizontal Distribution Area (HDA): Connections to active equipment. ✔ Equipment Distribution Area (EDA): Active Servers, Switches. Alternate hot and cold aisle. ✔ Zone Distribution Area (ZDA): Optionally between HDA and EDA. ZDA allows easy ✔ Backbone Cabling: Connections between MDA, HDA, and Entrance room ✔ High-fiber count cables connect ZDA to MDA or HDA. Low-fiber count cables connect ZDA to EDA as needed.

- 9. 3 Layer architecture network diagram 9 In the 3-layer architecture, there are three layers. There is now a core layer. The core layer is defined as the high-speed backbone of the network. These core layer switches are used to forward traffic as quickly as possible between networks, which are geographically separated. To put this simply, the core layer switches are used to interconnect each campus LAN to the others in a more efficient way. Data Center Network Figure-03: 3 Layer architecture network diagram
- 10. Data Center Network Architecture 10 Data center architecture, as an architectural design that establishes connections between switches and servers, is typically created during the data center design and construction phases. Besides, it designates the way that the server, storage networking, racks, and other data center resources will be placed and also addresses the interconnection of these devices. Figure-04: Standard Network Diagram of Data Center
- 11. Spine-Leaf Architecture of DCN 11 The spine-leaf architecture is a contemporary network design that improves data center performance and scalability and facilitates low-latency communication. ✔ Spine Switches Spine switches provide high- bandwidth connectivity and ensure efficient data flow between leaf switches. Spine switches act as the network’s backbone, as intermediate switches connect to all the leaf switches in the data center ✔ Leaf Switches Leaf switches are integral components of the spine-leaf architecture in data center networks. Their primary function is to connect servers and other network devices directly to the spine switches. Leaf switches handle data centers’ horizontal scalability and high-density server connectivity. Figure-05: Spine-Leaf Architecture of DCN
- 12. Active-Active Clustering Architecture 12 This is where the concept of Active-Active Clustering comes into the picture. Active-Active Clustering architecture is a perfect approach to eliminate zero downtime. ✔ The architecture of this clustering model is usually made up of more than two nodes that operate simultaneously to achieve redundancy and load balancing. ✔ Dense Wavelength-Division Multiplexing (DWDM) Dense wavelength-division multiplexing (DWDM) is an optical fiber multiplexing technology that is used to increase the bandwidth of existing fiber networks. It combines data signals from different sources over a single pair of optical fiber, while maintaining complete separation of the data streams. Figure-06: DWDM

GRE is used in DDoS attacks 19 Figure-09: GRE Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets in order to route various protocols over Internet Protocol (IP) networks. GRE can be used to carry out DDoS attacks, just like any networking protocol. One of the largest DDoS attacks on record occurred in September 2016. It was directed against a security researcher's website and was carried out using the Mirai botnet. The website was overwhelmed with packets that used the GRE protocol.
