Yesterday I attended the QoS Design session and blogged on the subject. After posting the blog on the internet I received an e-mail about a statement in the blog. I placed the following statement on the blog:
“Remember e-mail is NOT mission-critical.”
In the e-mail I received the following comment on this statement.
“What he forgot to mention, and which is the most important aspect, and the most disruptive part of QoS, is the politics around prioritization of applications. Everyone’s application is Priority 1, even if it is only e-mail.”
This is indeed correct. Everybody will try to convince you that their applications are the most critical for the application. The process of marking and classification involves a lot of politics.
Purely speaking as a network engineer and in the most circumstances, applications like voice and video conferencing are mission-critical and need more priority in comparison with e-mail and normal web browsing.
Thanks for bringing this up. Hope it is more clear now….
