Mac-Address And Aging

MAC ADDRESS

MAC LEARNING IS A PROCESS IN WHICH A SWITCH LEARNS THE MAC ADDRESSES OF DEVICES CONNECTED TO IT.

LEARNING THE MAC ADDRESS IS VERY IMPORTANT BECAUSE THE MAC ADDRES ENABLES THOUGHT TO FORWARD DATA PACKETS TO THE CORRECT DESTINATION.

IF THE SOURCE MAC ADDRESS IS IN THE TABLE, THE SWITCH KNOWS WHICH PORT THE DEVICE IS CONNECTED TO AND CAN FORWARD THE PACKET DIRECTLY TO THAT PORT. IF THE SOURCE MAC ADDRESS IS NOT IN THE TABLE, THE SWITCH WILL BROADCAST THE PACKET TO ALL OF ITS PORTS.

AGING

AGING IS A PROCESS IN WHICH THE SWITCH REMOVES FROM ITS MAC TABLE THOSE MAC ADDRESSES THAT HAVE NOT APPEARED IN THE MAC TABLE FOR A LONG TIME.

AGING IS IMPORTANT BECAUSE IT PREVENTS THE SWITCH FROM STORING MAC ADDRESSES THAT ARE NO LONGER VALID. IF A DEVICE IS DISCONNECTED FROM THE NETWORK, ITS MAC ADDRESS WILL NO LONGER BE VALID.

IF THE SWITCH DOES NOT AGE THE MAC ADDRESS, IT WILL CONTINUE TO FORWARD PACKETS TO THE PORT THAT THE DEVICE WAS PREVIOUSLY CONNECTED TO. THIS CAN CAUSE PROBLEMS, SUCH AS DATA LOSS OR SECURITY BREACHES.

THE DEFAULT AGING TIME FOR MAC ADDRESSES IS TYPICALLY 300 SECONDS, OR 5 MINUTES. THIS MEANS THAT IF A MAC ADDRESS IS NOT SEEN FOR 5 MINUTES, IT WILL BE REMOVED FROM THE SWITCH'S MAC TABLE. THE AGING TIME CAN BE CONFIGURED BY THE NETWORK ADMINISTRATOR.

TCP/IP MODEL

HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...
