[cisco-voip] Jabber/CIPC and QoS

[Lelio Fulgenzi]

good question Ben. i look forward to reading this thread.


i've been meaning to read up on mediaNet, and it seems it's more required than not, especially for QoS.


are you suggesting (with option 3) that there is software you can install on desktops? what about mobile devices?


QoS, both wired and wireless, will definitely be an interesting challenge.

So, I know this is an age old question that's debated, but I've been wondering if anyone here has a perspective here in regards to QoS for softphones. Obviously, with hardphones, you usually partition a separate VLAN with AutoQoS/DSCP tags, but that isn't applicable with softphones.



I've heard of three different options in the past, neither of which seem to be very simple to deploy, but all seem to be Jabber-centric.

1.      Configuring windows to perform DSCP tagging, and do DSCP QoS on the switches they are connected to, as well as trusting the device. Problems: Requires users to be local admins, openings for abuse and network impact due to blind PC trust.

2.      Configuring your switches with an access list that recognizes the ports Jabber does outbound to attach DSCP tags to them. Problems: Other programs could theoretically use those ports

3.      Installing Medianet services on all jabber clients; Configure all switches for medianet tagging. Problem: (I think?) Requires newer switches to use, maybe needs an additional server (I vaguely remember possibly needing prime collab?)?



Maybe I'm missing some things, but what approach have you guys taken for softphone/Jabber QoS? And on top of that, what options are there for CIPC (I know there's the auto qos trust cisco-softphone for cisco switches, but I don't believe there's a solution other than #1 for non-cisco switches)?
