[c-nsp] qos plan - advice please

[Aaron]

Is there an elegant, scalable, manageable way to roll-out/implement
network-wide/end to end qos over my ip/mpls network ?

 

I mean do I really need to go to each and every interface and apply
policy-map (service-policy) to all the interfaces of all my mpls lsr's ?!

 

Is it possible to enable something like rsvp and mpls te to allow for end to
end qos ?

 

What is the nicest way to do this ?

Identify the QoS capabilities of all the kit in the hops, identify any pinch
points, identify the traffic you would like to prioritise, by how much and
in which direction, identify which points will be using  L2, L3 and mpls exp
as the classification, if you get it all on paper it might start making more
sense.  Also I believe mpls has different QoS operating modes.

I work for an ISP/Telco/CATV company.  We recently (within the last year or
more) rolled out an MPLS network.  The mpls network is comprised of asr9k's,
asr901's, me3600's and uBR7246vxr's.... all those run in an ospf area in the
core igp.  ...then I add on top of all that , all the nice MPLS vpn's
(l2vpn's, l3vpn's).



How would you go about setting priority treatment to say for instance, all
of your cell backhaul traffic and also all of your telco voice traffic?
(the difference in the two is that cell backhaul is simply transported via
mpls from my perspective... BUT the internal telco voice traffic is what we
as a telephone company handle all the sip/mgcp signaling end to end, then
all the traditional backend voice call routing , etc ,etc (I'm not the phone
guy, but anyway))



1 - cell backhaul - my cell backhaul traffic is all edged-in on asr901's..
and edge'd out on asr9k's at the MTSO/MSC hand-off locations.. It's mpls
l2vpn vpws port-based is how I do it.. X2 .I other words, dual pw's per cell
tower site.  Two end to end xconnect's

2 - internal voip - my voice traffic is contained within a separate vrf
(mpls l3vpn).edge'd into the network on me3600's and core is 9k's.



Where would you start with an objective like that ?  ....getting priority
treatment to cell backhaul traffic and also internal voip ?

start?
