I don't have much knowledge on MPLS, but I have a scenario and need some help.
We are going to use an existing Microwave Network that consists of 20 hub sites configured in a ring topology and one of the DS3 channels to transport Ethernet traffic (with the help of media converters). My question is if we wanted QOS (Quality of Service) and wanted to prioritize voice traffic over data, do we really need MPLS? Will MPLS improve the performance of the already existing DiffServ Architecture defined by RFC2475, or does MPLS mearly just support DiffServ Architecture as defined in RFC3270?
Please help me out in answering my questions so we don't venture into technology we don't really need to support our customer.
let me clearify things to u
MPLS is a technology that used to make forwarding faster instead of forwarding packets based on routing table with MPLS the packet will be forwarded based on label switching which is faster easpecially for service provider networks
QoS is a mechnizem for bandwidth managment
so they both completely diffrent
and about DSCP it is the bits on the TOS ip header that used to mark traffic
while with mpls network the marking will be based on mpls exp which is not DSCP
so they are not related at all but work and coexist together in other words u can impliment MPLS with QOS but not MPLS implimented to imporve QOS or VOIP !!
so if u look only for QoS and voice priority then u dont need MPLS
