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.

We can see that most of the traffic is UDP port 53 DNS traffic but there is a little bit that is TCP port 53. To get an even better idea of the distribution of the traffic across the various hijacked prefixes, let’s take a look at a Sankey diagram.

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.

NGFWs can drill down beyond IP addresses, TCP/UDP ports, and network protocols to enforce policies based on packet content. Secure Web Gateway (SWG) Web-borne malware is one of the biggest threats facing enterprise networks today.

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.
