This flexibility allows applications to use any available port without causing conflicts with other services. How does the TCP port work? TCP ports operate at the transport layer of the Internet Protocol Suite. What is Transmission Control Protocol (TCP)? What is User Datagram Protocol (UDP)?

This backend fabric utilizes the RoCEv2 protocol, which encapsulates the RDMA service in UDP packets for transport over the network. Initially, our GPU clusters used a simple star topology with a few AI racks connected to a central Ethernet switch running the non-routable RoCEv1 protocol.

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. 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. Let’s take a look at how this works. What is BGP Route Hijacking?

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.

First we’ll look at what protocol the traffic consists of. We can get an initial feel for this by looking a little deeper at the ports involved. What we see is that in addition to 0 and 53 there’s a fairly high level of packets per second being thrown at port 4444 (green line in graph). We can do this in multiple ways.

IP Versions and Internet Protocols. As for IP protocols, when we look at which ones our customers are most commonly seeing on their networks (above right), it’s not surprising that TCP (protocol 6, for those not familiar) comes out on top, with almost 71% of the traffic. Port Numbers and Services.
