Internet protocol specifications are instructions designed for engineers to build things. Protocol designers take great care to ensure the documents they produce are clear. The Internet is central to everyone's lives, and we depend on these implementations. Any deviations from the specification can put us at risk.

CCNA: TCP/IP Stack TCP/IP Stack is the most widely used protocol stack. TCP/IP stack is a conceptual model consisting of network communication protocols. It specifies how data should be packetized, addressed, transmitted, and routed across the network. TCP/IP networks use TCP or UDP protocol at this layer.

The Internet is designed to provide multiple paths between two endpoints. Attempts to exploit multi-path opportunities are almost as old as the Internet, culminating in RFCs documenting some of the challenges. As a result, Internet devices usually use a single path and let the routers handle the path selection.

Although theres more than one way to control cross network communication, this blog will cover the method of using Network Security Groups (NSG) to achieve this goal. NSGs can be deployed through the Azure Marketplace and associated to either a subnet, VM network interface or both.

While redundancy is a significant contributor to network resilience, other mechanisms, protocols, and methods can also contribute to overall network resilience. Additional network resilience mechanisms Successfully routing a packet over the internet from its source to its destination is not trivial.

In most cases, these patterns are evaluated on a single network packet, rather than a sequence of flows between a client host and a server. There exist several protocols, from different network layers that can be used for OS fingerprinting. Figure 1 displays these protocols, based on the Open Systems Interconnection (OSI) model.

On a network, configurations are constantly changing. Unfortunately, configuration change accidents can happen that bring down parts of the network. Interface dropping packets. Interface issues caused by misconfigurations, errors, or queue limits lead to network traffic failing to reach its destination.
