IP SLA

IP SLA IS A CISCO IOS FEATURE THAT ALLOWS YOU TO MONITOR THE PERFORMANCE OF YOUR NETWORK. IT CAN BE USED TO MEASURE THINGS LIKE LATENCY, JITTER, AND PACKET LOSS. IP SLA WORKS BY SENDING A PROBE FROM ONE DEVICE TO ANOTHER AND MEASURING THE TIME IT TAKES FOR THE PROBE TO TRAVEL FROM THE SENDER TO THE RECEIVER AND BACK.

IP SLA IS A VALUABLE TOOL FOR NETWORK ADMINISTRATORS TO MONITOR THE PERFORMANCE OF THEIR NETWORK. IT IS A RELATIVELY SIMPLE TOOL TO CONFIGURE AND USE, BUT IT IS IMPORTANT TO BE AWARE OF ITS LIMITATIONS BEFORE DEPLOYING IT IN A NETWORK.

HERE ARE SOME OF THE BENEFITS OF USING IP SLA:

IT CAN BE USED TO MONITOR A VARIETY OF NETWORK PATHS AND APPLICATIONS.

IT CAN BE USED TO IDENTIFY PERFORMANCE PROBLEMS AND TROUBLESHOOT NETWORK ISSUES.

IT CAN BE USED TO ENSURE THAT YOUR NETWORK IS MEETING YOUR SERVICE LEVEL AGREEMENTS.

HERE ARE SOME OF THE LIMITATIONS OF IP SLA:

IT CAN BE USED TO MEASURE ONLY A LIMITED NUMBER OF PERFORMANCE METRICS.

IT CAN BE RESOURCE-INTENSIVE, ESPECIALLY IF IT IS USED TO MONITOR A LARGE NUMBER OF NETWORK PATHS.

IT CAN BE DIFFICULT TO TROUBLESHOOT PROBLEMS WITH IP SLA.

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...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...

OSI Refrance Model

OSI MODEL 1. THE OSI MODEL WAS DEVELOPED BY THE INTERNATIONAL ORGANIZATION FOR STANDARDIZATION (ISO) IN THE LATE 1970S. THE MAIN ARCHITECT OF THE OSI MODEL WAS HUBERT ZIMMERMANN, A FRENCH SOFTWARE ENGINEER. 2. ISO REPRESENT A 1947 MORE THAN WORK AND AGAIN REPRESENTS A ISO IN 1977 AND MORE THAN WORK AN REPRESENT IN 1983 A OSI REDFRENCE MODEL. 2. HIS MODEL REPRESENT A 7 LAYER 3. OSI MEANS (OPEN SYSTEMS INTERCOMMUNICATIO). 1. APPLICATION LAYER 1. THE APPLICATION LAYER IS USED BY END-USER SOFTWARE SUCH AS WEB BROWSERS AND EMAIL CLIENTS. IT PROVIDES PROTOCOLS THAT ALLOW SOFTWARE TO SEND AND RECEIVE INFORMATION AND PRESENT MEANINGFUL DATA TO USERS. 2. IT SENDS ITS DATA TO THE FORM OF THE PDU. PROTOCLS AND DEVICES USED IN LAYER THERE ARE SOME PROTOCOLS THAT WORK AT THE BACKEND OF THE APPLICATION LAYER. WHICH IN TURN WORKS AT THE APPLICATION LAYER. MANY DEVICES USE IT AT THE APPLICATION LAYER. PROTOCOLS FTP (FILE TRANSOFER PROTOCOL) DNS (DOMA...
