Spanning Tree Protocol (STP)

Spanning tree protocol is a network protocol that is used to ensure a loop-free topology. The basic function of the STP is to select which port will be use if there are occurs in redundant link which act as backup if the active link fails.The inventor of the STP is called Radia Perman, which is a software designer and network engineer, How the STP works? Root Bridge(bridge and switch is same thing) --> switch with the lowest mac address become root bridge,if and only if the priority is same Elect Root Port (RP) --> root port is port on the non root bridge pointing back to root bridge depend on speed (higher speed == lower cost) and port id (lowest port id win) Elect Designated Port (DP) --> port at root bridge pointing toward non root bridge Elect Non-designated Port (NDP) --> port on non-root bridge pointing towards root bridge that is block automatic become standard port The switch will sent Bridge Protocol Data Units (BPDU) to nearby switch (default sent every

Agent Architectures

An agent is a computer system that capable of flexible autonomous action. While Agent architecture is the model for software agents and intelligent control system. Basically there are 3 type of architecture which are: Symbolic/logical (Proactive) Reactive Hybrid Symbolic Architecuture Symbolic Reasoning Agent At the beginning, all the agents is designed were symbolic reasoning agents. It is the expressions that can propose to the agents to use the expression logical reasoning to decide what to do.  To build an agent, there are exist a classical approach which is to view the system as a particular type of knowledge-based system. This paradigm we called as symbolic AI, it contain the intelligent behavior can be generated in a system by giving that system a Symbolic representation of its : Environment Desired behavior Syntactically manipulating this representation Symbolic is an architecture that : contains explicitly represented, symbolic model of world mak
