The current electronic data centers need high power requirements, so as to offer this one a large bandwidth, low latency and low power consumption. In this context, a dynamic Flat Ball topology-based gigabit ethernet passive optical network (GE-PON) architecture with five transceivers having low latency and bandwidth reconfiguration potential to minimise energy consumption using passive devices at data centers, is presented in this paper. This architecture offers 26dB and 40dB loss in uplink and downlink respectively with 200 nodes, compared to Sandwich tree and Sirius architectures. Compared to the conventional GE-PON, it allows 9dBm in downlink and 10dBm in uplink energy saving with 1ms traffic delay. Also, it offers energy ratio up to 39% in downlink and 37% in uplink having 50 Erlang network loads at 25×100Gbps traffic rate. It provides faithful data transmission over 100km bidirectional channel considering fiber impairments and noise. The proposed design can be extended to 1:64 split ratio providing maximum 35ms in downlink and 31ms in uplink transmission delay. Comparing the Flat ball topology with other existing ones indicate the superiority of the former architecture in terms of less cost, power consumption, traffic delay and high scalability as well as flexibility.

Existing electronic data sources desire high‐power requisites, in order to obtain a large bandwidth, minimum power dissipation and low latency in networks. In this instance, a gigabit ethernet passive optical network (GEPON) architecture based on a dynamic Flat Ball topology incorporating multi‐transceivers to minimize network energy consumption via passive devices along with bandwidth reconfiguration potential and low latency is reported in this paper. The proposed architecture connected with 200 nodes exhibits 26 as well as 40 dB total loss in uplink as well as downlink considerably, compared to Sirius and Sandwich tree. Also, Flat ball GEPON architecture permits 9 and 10 dBm energy saving in downlink as well as uplink, respectively, than conventional GEPON architecture at 1 ms delay. The proposed architecture with 50 Erlang load allows energy ratio of 39% in downlink and 37% in uplink, at 25 × 100 Gbps traffic rate for 55 nodes. Besides this, the faithful fiber range of 100 km considering fiber no‐linearities and impairments can be obtained successfully. The architecture can be bordered with 1:64 splitting ratio with 35 ms in downlink as well as 31 ms in uplink transmission delay at bit error rate of 10−3. Additionally, on comparing the proposed topology with existing architectures depict its superiority with minimal implementation cost, low‐power dissipation, less traffic delay as well as high scalability and high flexibility.

Human computer interaction (HCI) aims to enhance product effectiveness and efficiency by empowering users. This research examines corrosion resistance in alloys, a concern due to technological advancements. Metals and alloys are susceptible to degradation, leading to functionality loss, structural collapse, and environmental contamination. Improving corrosion resistance is crucial for product efficiency. In this paper, HCI identifies requirements that emphasize taking an existing hexagonal closely packed (HCP) network, investigating the network for requirements in the form of vertices and edges, mapping different vertices and edges of the network graph with topological invariants, solving the network graph by invariants, and providing results for modeling and design of advanced networks and architectures. The HCI also ensures and investigates the optimization of results produced under the specifications. The study examines network graph results for irregularities, providing guidelines for engineers and manufacturers to create advanced alloy architectures with characteristics through mathematical and graphical methods.
