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.

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.

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.

Figure 1: Different network protocols for OS identification based on the OSI model Starting from the bottom of the stack, at the data link layer, exists the medium access control (MAC) protocol. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device.

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.

Internet protocol specifications are instructions designed for engineers to build things. The Internet is central to everyone's lives, and we depend on these implementations. Cloudflare has supported QUIC on our global network in some shape or form since 2018. Any deviations from the specification can put us at risk.

Flow logs are a valuable source of network traffic information in AWS. They capture detailed metadata about the traffic flowing through various components of your network, such as VPCs, subnets, and network interfaces. AWS Transit Gateways act as a centralized hub for connecting multiple VPCs and on-premises networks.
