BGP is also vulnerable to attacks based on misinformation. Malicious actors can flood a router with bad packets in a denial-of-service attack, for example. They can also claim to be the source of routing information for an AS and temporarily control where traffic headed from that AS goes, a...
Learn what Border Gateway Protocol (BGP) is, how it works, and its characteristics. BGP takes into consideration all the different peering options a router has and chooses the one closest to where the router is.
It encapsulates its data directly in IP packets with protocol number 89. This is in contrast to other routing protocols, such as the Routing Information Protocol (RIP) and the Border Gateway Protocol (BGP). OSPF implements its own transport error detection and correction functions. Protocol Layer...
The foundation of the Internet is built on a protocol calledInternet Protocol(IP). IP provides a set of rules that govern how data is transmitted across networks. Every device connected to the Internet is assigned a uniqueIP addresswhich serves as its virtual identifier. IP addresses play a cr...
To comprehend how to use traceroute it is crucial to have a basic understanding of the Internet Protocol (IP). IP is the underlying protocol that enables communication between devices over the Internet. It defines how data packets are formatted, addressed, and transmitted across networks. IP addr...
Generally, BFD is not used independently. Instead, it is used together with the interface status or routing protocols (such as static routing, OSPF, IS-IS, and BGP). This section describes two typical application scenarios of BFD. For other application scenarios, seeApplication Scenarios for BFD...
Firewall security policies are also called firewall rules and firewall policies. This document describes the definition, composition, configuration, and matching principles of security policies. Firewall Security Policy: What It Is and How It Works Firewall Security Policy: What It Is and How It ...
In this issue, we take a closer look at the Secure Sockets Layer (SSL), which is used for Web transactions. William Stallings explains how SSL works and how it is becoming the standard for Web security. If you want to learn about computer networks, many options are available, including ...
How it worksA user (Alice) requests a file (also called an asset) by using a URL with a special domain name, such as <endpoint name>.azureedge.net. This name can be an endpoint hostname or a custom domain. The DNS routes the request to the best performing POP location, which is ...
It is therefore hardly surprising that not only providers but also an increasing number of experts see these Software Defined Data Centers (SDDCs) as the data center model of the future. The following sections explain why this is the case and how a software-controlled network works at all. ...
