Layer about how the trade offs should be made for the particular packet This facility is the Type of Service or ToS facility ToS settings allow the service provider to prioritize time sensitive traffic such as voice plus video to ensure minimized packet loss and delay through their network When providing end to end QOS it is important that the voice plus video traffic be placed in the correct queues to deliver a higher QOS than regular traffic Regular traffic that is not time sensitive can be delayed with little or no indication to the user while the slightest delay in voice plus video can cause auditable differences The ToS byte setting helps prioritize traffic going to the WAN so a provider can prioritize the traffic correctly in its network Although the ToS facility has been a part of the IP specification since the beginning it has been little used in the past However the Internet host specification now mandates that hosts use the ToS facility Additionally routing protocols including OSPF and Integrated IS IS have been developed which can compute routes separately for each type of service These new routing protocols make it practical for routers to consider the requested type of service when making routing decisions How the ToS Byte Setting Works For all RTP traffic voice and video the Polycom V7IU 4300T marks the ToS byte in the IP header as High Priority and strips set to 0 the ToS byte for all other tr
