Experiences With Class of Service (CoS) Translations in IP/MPLS Networks

Tags:
switching

Overview This paper presents some experiences with Class of Service (CoS) translation in IP and MPLS based networks. IP provides CoS in the form of eight priority classes that can be used to distinguish between a variety of traffic types. Since most of the layer-2 technologies provide support for strict QoS, an appropriate translation from the coarse grained IP CoS to the fine-grained layer-2 QoS is fundamental to obtaining desired end-to-end throughput. Multiprotocol Label Switching (MPLS), residing in between IP and layer-2 in the protocol stack, provides an interface to translate IP CoS to appropriate layer-2 QoS. This paper presents some of the results obtained by using MPLS CoS with relative and fixed bandwidth allocation to MPLS classes.

Ipv6: An acronym to shake the networked world

This can be done using MPLS (Multiprotocol Label Switching) or tunnelling. The priority allocated to a data package on the net can be coded here too. It supports Quality of Service (QoS) and thus increasingly important real time communication for...

Has Gigabit Ethernet come of age?

Rufner said although ATM is moving towards new carrier requirements, Ethernet "is starting to make inroads in the MAN as a cost-effective switching layer because of multi protocol label switching [MPLS]".

ITU 03: C&W looks to allowing global QoS

IP VPNs often now take advantage of a technology called MPLS (multiprotocol label switching) for greater flexibility and quality of service (QoS), however QoS can become difficult for carriers to maintain as traffic jumps from one network to...

Indian telecoms explosion tempts Cisco

Bharti Infotel, a subsidiary of Bharti Tele-Ventures, one of four major telecom providers in India, announced on Wednesday that it has chosen Cisco to be the main equipment supplier to build its IP-based multiprotocol label switching (MPLS) network.

VoIP primer: How it works - and what the jargon means

With MPLS in particular, applications can be graded into a number of classes. Voice is typically given the highest priority, in MPLS terms this is likely to be Platinum, while email may be Bronze. With DiffServ, information about priority is places...

Peter Cochrane's Blog: Fat cat telcos are killing the net

The net as it stands is a wonderfully chaotic place, fundamentally incapable of providing any form of real-time service - voice, video, any form of instant messaging or human interaction - with any guaranteed quality of service (QoS).

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
