When companies started outsourcing the hosting of their websites to the likes of Akamai and AWS, network teams learned quickly that many work- and non-work related applications shared the same IP address. The Internet Engineering Task Force (IETF) is also working toward changes that will impact pervasive monitoring.

This blog will explore the key protocols within the transport layer, focusing on TCP ( Transmission Control Protocol ) and UDP (User Datagram Protocol) in detail. This layer operates on two primary protocols: TCP and UDP , each serving different purposes in data transmission. What is the Transport Layer?

Because of this convergence, automated security engines and customized policies benefit from shared context and visibility allowing true single-pass processing and more accurate security verdicts. This includes elements like IP address, subnet, username, group membership, hostname, remote user, site, and more.

For example, during an attack, service provider network engineers need to be skilled at finding attacks, choosing an appropriate mitigation strategy, and have proper access to the infrastructure to apply it. For destination-based RTBH, the victim’s destination IP address becomes completely unreachable. IP Protocol.

In a recent blog post by Kentik Solutions Engineer Eric Graham we explained how we “dog food” our own NPM solution to troubleshoot network performance issues within our own cloud-based application. Next we set Metric (still in the Query pane) to look at the percentage of TCP retransmits. How does it work?

Next, each Cato PoP acts as TCP proxy to maximize the transmission rate of clients, increasing total throughput dramatically. Cato uses a single DPI engine for both network routing and security decisions. Routing across a global private backbone end-to-end also reduces packet loss that often occurs at the handoff between carriers.

It isn’t so much that packet loss is a huge problem — TCP and QUIC were engineered in anticipation that lost packets would be inevitable. Latency : Missing packets in connection-oriented protocols such as TCP and QUIC result in lost packets getting resent. UDP vs. TCP. Packet Loss Causes Problems with Cloud Applications.
