As a result, Internet devices usually use a single path and let the routers handle the path selection. Enter Multi-Path TCP (MPTCP), which exploits the presence of multiple interfaces on a device, such as a mobile phone that has both Wi-Fi and cellular antennas, to achieve multi-path connectivity. There is another way.

Vendor’s data centers have private links to their own routers which are set up in AWS Direct Connect Locations. Direct Connect Location: a high-speed AWS network traffic exchange center that contains both AWS Direct Connect routers and vendor’s routers. The VGW is a VPC edge router for exposing internal traffic.

Flow logs are generated only from VPCs, subnets, and network interfaces. Instead, Transit Gateways act as cloud routers by maintaining their own routing tables and attachments. One way to quickly instrument this change is to configure flow logs on an interface basis. Analyze Your VPC Flow Logs!

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.

Maintaining network connectivity with BGP Border Gateway Protocol (BGP) is a routing protocol that connects different networks over the internet. It is used to maintain network connectivity by helping routers find the best path for traffic to travel through.

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.

Some of these devices an enterprise network engineer owns and manages, and a lot of it they don’t. Rather than collecting only flow data from routers, or only eBPF information from containers, the fact that application traffic traverses so many devices means we need much more data to get an accurate view of what’s happening.
