Today, data center networks (DCNs) are built using multi-tier architecture. These large-scale networks face many challenges, such as security, delay, low throughput, loops, link oversubscription, TCP Incast and Outcast, etc. In this paper, a TCAM (Ternary Content Addressable Memory) based routing technique is proposed, augmenting the routing capabilities of multi-tier architectures in large scale networks. The routing complexities in these architectures are rectified and improved by implementing an additional TCAM based routing table in Leaf/ToR switches for a specific number of compute nodes in particular Pods, and it is scalable to whole datacenter nodes. To test the model, we implemented two prototype models: one depicting our proposed TCAM based switch and the other is a typical Top-of-the-Rack (ToR) switch and compared the performance of the proposed model and if any overhead introduced in it. The preliminary results show that our TCAM based routing table technique is fast and it forwards the network packets at line-rate, does not introduce considerable latency, on-chip resources power consumptions is less than 3%, and helps to solve or mitigate the above critical problems that are present in the current large DC's three-tier architecture, especially in Top of the Rack and aggregation layers switches. INDEX TERMS Data center networks, TCAM tables, top of the rack switches, link oversubscription, TCP incast and outcast, loops.

WiFi has become one of the major network access networks due to its simple technical implementation and high-bandwidth provisioning. In this paper, we studied software defined WiFi networks (SDWN) against traditional WiFi networks to understand the potential benefits, such as the ability of SDWN to effectively hide the handover delay between access points (AP) of the adoption of the SDWN architecture on WiFi networks and identify representative application scenarios where such SDWN approach could bring additional benefits. This study delineated the performance bottlenecks such as the throughput degradation by around 50% compared with the conventional WiFi networks. In addition, our study also shed some insights into performance optimization issues. All of the performance measurements were conducted on a network testbed consisting of a single basic service set (BSS) and an extended service set (ESS) managed by a single SDN controller deployed with various laboratory settings. Our evaluation included the throughput performance under different traffic loads with different number of nodes and packet sizes for both TCP and UDP traffic flows. Handover delays were measured during the roaming phase between different APs against the traditional WiFi networks. Our results have demonstrated the tradeoff between performance and programmability of software defined APs.

The emerging software defined networking (SDN) has great potential for enabling novel networking solutions to improve performance and management of distributed systems such as smart homes. In this paper, we studied the possible technical development trend of software defined wireless networking (SDWN) technologies toward the design and implementation of a smart home router based on the Intel Galileo Gen 2 programmable platform. We instrumented this platform by integrating various open-source software projects such as OpenWrt into a home router to support intelligent home wireless networking and provide lowcost connectivity solutions for the Internet-of-Things using WiFi and another cutting-edge wireless communication technology, "Bluetooth Low Energy. We conducted a series of experiments on our router and presented some preliminary results of our smart home network testbed. Our experiment study may provide empirical experiences into constructing evolvable and cost-effective software defined smart home routers with a good trade-off between performance, flexibility and cost.
