WebSignificant fields in the IPv4 header include: Version - Contains a 4-bit binary value set to 0100 that identifies this as an IP version 4 packet. Differentiated Services (DS) - Formerly called the Type of Service (ToS) field, the DS field is an 8- bit field used to determine the priority of each packet. WebInternet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January 1983. It is still used to route most Internet traffic …

WebDifferentiated services (DiffServ) is an IPv4 header field that is used to define the priority of each packet. The first 6 bits identify the value that is used by the QoS mechanism, and the last 2 bits identify the value that can be used to avoid packet dropping during network congestion. Traffic class is an IPv6 header field that is equivalent ... WebJul 29, 2024 · You can create QoS policies that define network traffic priority with a Differentiated Services Code Point (DSCP) value that you assign to different types of network traffic. The DSCP allows you to apply a value (0–63) within the Type of Service (TOS) field in an IPv4 packet's header, and within the Traffic Class field in IPv6.
