As we all know, the computer networks rely on cache to improve its performance. For example, the DNS caches resource records, the CDN caches content, and the SDN caches flow rules. However, on one hand, we know that caches are vulnerable to attacks such as cache overflow and cache pollution attack. The Existing defenses to protect the cache can be mainly divided into two parts, which are attack traffic detection, or using system-specific countermeasures. More importantly, all these mechanisms are external. Therefore, it remains to find out: how well can a cache to protect itself from attack. On the other hand, in-network caching and flexible routing are two of the most celebrated advantages of next generation network infrastructures. Yet few solutions are available for jointly optimizing caching and routing that provide performance guarantees for an arbitrary topology. In this thesis, we are going to explore different perspectives of cache network management, trying to make it resilient to mansion attacks, security threads, or naturally occurring faults. In our first piece of work, we zoom into a single cache node, improving its resilience by designing/picking the suitable replacement policy. We study this problem by charac terizing the attack resilience of cache replacement policies under cache pollution attack, which is also a form of Denial of Service attack. To understand the cache performance under such attacks, we analyze a suite of representative replacement policies under the framework of TTL approximation in how well they preserve the hit ratios for legitimate users, while incorporating the delay for the cache to obtain a missing content. We further develop a scheme to adapt the cache replacement policy based on the perceived level of attack. Our analysis and validation on real traces show that although no single policy is resilient to all the attack strategies, suitably adapting the replacement policy can notably improve the attack resilience of the cache. Motivated by these results, we implement selected policies as well as policy adaptation in an open-source SDN switch to manage flow rule replacement, which is shown to notably improve its resilience to pollution attacks. As our second piece of work, we zoom out to the multi-hop cache network, for which the control plane is centralized. Suppose there is a centralized optimizer, as in a Software Defined Network (SDN) that oversees the storage of all the content, routing of all the requests(flows), our focus is how to jointly optimize caching and routing. We take a holistic approach towards this fundamental problem by analyzing its complexity in all the cases and developing polynomial-time algorithms with approximation guarantees in important special cases. We also reveal the fundamental challenge in achieving guaranteed approximation in the general case and propose an alternating optimization algorithmwith good performance and fast convergence. Our algorithms have demonstrated superior performance in both routing cost and congestion compared to the state-of-the-art solutions in evaluations based on real topology and request traces. Shifting focus to cache vulnerabilities (in SDN), our third piece of work tackle the exposed nature of internal switch flow table sizes. Though previous work exposed edge switch manipulation, existing methods falter when navigating deeper within the network. Our work bridges this gap by unveiling the first solution to infer internal switch flow table sizes. Leveraging crafted probing sequences and robust statistical analysis, our Multi-Switch Size Inference (MSSI) algorithm estimates sizes along probing paths. This information feeds the Multi-Switch Size Matching (MSSM) algorithm, which pinpoints specific switches based on size intersections from multiple paths. Importantly, our solution relies solely on readily available Round Trip Time (RTT) measurements, making it broadly applicable without specialized network access. Rigorous theoretical analysis establishes accuracy bounds and correctness guarantees for MSSI and MSSM. Extensive Mininet experiments further validate our approach, showcasing its superior accuracy compared to state-of-the-art techniques. Our future research journey tackles diverse network challenges, from enhancing cache resilience and securing SDN to optimizing data transmission in dynamic environments. This future thrust focuses on the latter, specifically within the realm of overlay networks. These versatile networks play a critical role in modern data transmission, but their dynamic nature requires adaptable routing strategies for optimal performance. To address this dynamic challenge, we delve into the world of multi-arm bandits algorithms. These algorithms offer a promising framework for online shortest path routing in overlay networks. By leveraging the principles of exploration and exploitation, our proposed approach continuously evaluates and learns from real-time data, adjusting routing decisions based on the most up-to-date network conditions. This adaptive approach promises to improve efficiency and performance in overlay networks, ensuring the swift and seamless delivery of data even in the face of constant change.

The increasing demand for sophisticated network applications, allied to the growth of the Internet traffic, has lead to great efforts in the search of improvements in data transmission technologies with the intention of satisfying the increasing demand for bandwidth. So far as optical networking is concerned, WDM (Wavelength Division Multiplexing) appears as the main advance in the transmission area, because it allows transmission rates near to the theoretical limit of optical fibers, of the order of dozens of terabits a second [1]. An essential issue in optical network design is defining how the network will be controlled, that is, what type of signalling will be responsible for resource reservation, route determination and fault handling, among other functions that constitute the control plane. Label switching, which in IP networks is exemplified by MPLS (Multiprotocol Label Switching) [2], was extended through GMPLS (Generalized Multiprotocol Label Switching) [3] to operate with several different network technologies, where the label can be represented in other ways, for example, as time-slots in TDM networks, as physical switch ports and as wavelengths (lambdas) in WDM networks.
