Wireless technologies has become very popular in recent years because allows users to be connected all the time without the need of a physical medium to transport data. Many mobile devices are equipped with multiple network interfaces to be connected. However, there is no mechanism to allow the use of these multiple network interfaces simultaneously. The use of a single network interface at the time is not enough to for today's application requirements. Bandwidth aggregation is a solution to this problem. However, current solutions require the placement of additional infrastructure to the network or the creation of a new transport protocol, which incurs into additional modification of applications. In this paper a solution to this problem is presented by only modifying the Transmission Control Protocol to allow the use of multiple network interfaces to send traffic simultaneously increasing the throughput while being transparent to users and applications.

This paper aims to present patterns for collaborative learning directed by cases of uses and sequence diagrams for re- use of learning objects. A proposal is based taking the theory from the UML model and proposing an extension to model a collaborative learning with: cases of use (CLUC)and sequence diagrams for collaborative learning (CLSD). This paper is based on the MACOBA model which proposes by the construction levels of collaborative learning objects(CLO). The work is centered in the analysis level in one second part which responds to model what must make the object of learning. In this way the elements will appear to model the collaborative learning in promotion of re-use inthe analysis phase.
