ECMP and path pinning We initially considered the widely adopted ECMP, which places flows randomly based on the hashes on the five-tuple: source and destination IPs, source and destination UDP ports, and protocol. However, and as expected, ECMP rendered poor performance for the training workload due to the low flow entropy.

NGFW also supports the creation of custom application definitions to enable identification of specific apps based on TCP/UDP port, IP address, or domain. Additionally, a Deep Packet Inspection (DPI) engine enables contextualization of traffic. SWG focuses on layer 7 traffic exclusively and inspects inbound and outbound flows.

Port Numbers and Services. Now let’s take a look at TCP/UDP port numbers, so we can get an idea of what kind of services are in use. To be honest, I had to go look up what some of these other protocols are as I have not seen those protocol numbers in years.
