Understanding IEEE 802.1P and IP DiffServ
With the introduction of technologies such as Voice over IP and digital video, network managers and administrators have had a tough time keeping up with ever-increasing bandwidth requirements. Traditionally “best effort” Local Area Network protocols, like Ethernet, face a difficult time handling the high priority requirements that these technologies bring with them. However Quality of Service (QoS) promises a better way of handling these new challenges, while increasing reliability and quality. In QoS the bandwidth, error rates and latency can be monitored, sampled and potentially improved. QoS also delivers the set of tools to help deliver data efficiently by reducing the impact of delay during peak times when networks are approaching full capacity. The following webinar goes into greater detail on defining what QoS is and why you would employ it in your network.
