This collection spotlights the authentic voices of plurilingual learners, bringing together autoethnographies of over twenty graduate students to deepen current understandings of lived experiences of plurilingualism. The volume begins with outlining foundational work on plurilingualism in language education up to this point, with the body of work on plurilingual subjectivities historically focusing on researchers’ and practitioners’ gazes, rather than students. The book moves into short autoethnographies of graduate students at the University of Toronto enrolled in a graduate education course over three years. Employing autoethnography as the primary methodology allows the space for privileging authentic voices of plurilingual learners in their own words, learners whose individual lived experiences are uniquely contextualized within the lens of plurilingual theory. The volume and diversity of perspectives showcased offer a unique window into the diversity and commonalities among plurilingual learners, offering opportunities for reflection on directions for future research. This book will be of interest to students and scholars in applied linguistics, language teaching and learning, and language education.

Cloud Data Center Network Architectures and Technologies has been written with the support of Huawei's vast technical knowledge and experience in the data center network (DCN) field, as well as its understanding of customer service requirements. This book describes in detail the architecture design, technical implementation, planning and design, and deployment suggestions for cloud DCNs based on the service challenges DCNs encounter. It starts by describing the overall architecture and technical evolution of DCNs, with the aim of helping readers understand the development of DCNs. It then proceeds to explain the design and implementation of cloud DCNs, including the service model of a single data center (DC), construction of physical and logical networks of DCs, construction of multiple DCNs, and security solutions of DCs. Next, this book dives deep into practices of cloud DCN deployment based on real-world cases to help readers better understand how to build cloud DCNs. Finally, this book introduces DCN openness and some of the hottest forward-looking technologies. In summary, you can use this book as a reference to help you to build secure, reliable, efficient, and open cloud DCNs. It is intended for technical professionals of enterprises, research institutes, information departments, and DCs, as well as teachers and students of computer network-related majors in colleges and universities.
