A Review of Link Aggregation Control Protocol (LACP) as a Link Redundancy in SDN Based Network Using Ryu-Controller

A reliable network is an absolute requirement for telecommunication networks at this time. This is in line with the growing number of users who need a reliable and uninterrupted connection to the server. Link Aggregation is one of the techniques that can be used to provide a reliable network. Link Aggregation System combines two or more links into one logical link, which is characterized by the use of a single IP address. During the communication between host and server, whenever the used link is broken or terminated the other active link can act as redundancy to resume that communication. This mechanism is called link redundancy. This mechanism will not run without the existence of another mechanism that monitors the condition of the links, which is either connected or disconnected. That mechanism is called link monitoring. Link monitoring used in this simulation is the Media Independent Interface (MII). In this simulation, we used Ryu-Controller and mininet Simulator to test the reliability of Link Aggregation-based SDN (Software Defined Network). During the simulation, we analyzed failover performance and how the Link Aggregation distributes the connection across the links for every which comes from a different source. From the simulations, we confirmed that link redundancy, the same data rate for every connection, to some degree, worked as intended.
