Summary:
|
This Supplement presents a proposal to enable the deployment of Inter-provider Quality of Service (QoS). The Supplement begins from the observation that QoS based on the Differentiated Services architecture defined in RFC 2475 is now widely deployed within the networks of single providers. This is especially the case for providers of network-based VPNs (see, for example RFC 2547, RFC 4364). Some providers are now beginning to interconnect with each other via "QoS-enabled peering" in an attempt to offer QoS that spans the networks of multiple providers. However, in the absence of appropriate standards and established procedures for management, trouble-shooting, monitoring, etc., such interconnections are likely to be challenging and labour-intensive. This Supplement seeks to identify the key issues that service providers need to agree upon if inter-provider QoS is to be readily deployable.
