This chapter proposes an architecture for implementing e-laboratory environment by taking into account several aspects concerning not only the educational process, but also the network infrastructure, the collaboration and quality of service (QoS) requirements, the types of content, etc. This is a flexible, parametrical, and component-oriented architecture designed to support collaboration among different actors or entities of the e-learning environment. According to the diverse aspects of QoS that an e-learning service comprises, this architecture was tested with different network loads. Experimental results show that improvements caused by traffic differentiation, even without special network loads, become even more significant as the number of users increases.
