[Openv6] ***SPAM*** 7.888 (5) Fw: 转发: APONF (Application-based Policy for Network Functions): new BOF for IETF 90 (requesting comments)

[Ying Cheng <[e-mail]>]

Hi all,

These two drafts are valuable. However, it is important to analyze the related scenarios as the first step. As representative of telecom operator, we have accumulated some experience in this area and would like contribute the following texts as use case for further study.


A tier 1 IDC operator, providing server hosting, bandwidth, and value-added services to enterprises and ISPs, has more than 10 data centers and more than 1Tb bandwidth in a capital city. In current IDC network, traffic is routed via configuring policy routes and adjusting routes prioritization to choose an outcoming link. This kind of static provisioning brings high costs and poor operability. Link bandwidth resource in data centers is not made good use of. 
Services usually do not have a consistent bandwidth requirement at different times of a day, e.g. video ISP usually require more bandwidth at non-working hours but require less bandwidth at working hours. Some customers have relative high QoS requirement for their services, e.g. IM. Static bandwidth and QoS provisioning for all the customers and services is not reasonable and not cost-effective. 
The operator wants to be able to optimize traffic routes dynamically so as to have load balance between data centers and links, and direct customer traffic via policies based on customer grade and QoS requirement. It will also be useful to monitor the real-time traffic flow and have a visualized report. 

Traffic engineering application can work out dynamic traffic adjustment demand to the network based on link stats reported by the network. APONF will define a policy model mapping application's demands to policies (e.g. traffic redirection based on customer's grade and link stats), which can be directly enforced by network devices, to meet the operator’s needs.


We expect that this use case is helpful for these drafts and would like to take part in the discussion of this topic.

Thanks and best regards,

主题: [Openv6] APONF (Application-based Policy for Network Functions): new BOF for IETF 90 (requesting comments)
 
Hi all,
 
Please note that a request for a BOF associated with Openv6 has been requested for IETF 90.
 
The name of this BOF is:
 
APONF (Application-based Policy for Network Functions).
 
The main goal of APONF is to specify the application-based policy protocol(s), mechanisms and models required by transport applications to easily, accurately, and efficiently select and use the available communication network capabilities, i.e., network management and/or traffic policies. 
 
For more details on APONF, please see:
http://trac.tools.ietf.org/bof/trac/#
 
Please note that in association with this BOF two Internet drafts have been (up to now) submitted . 
These drafts are:
 
APONF problem statement:
http://tools.ietf.org/id/draft-karagiannis-aponf-problem-statement-00.txt
 
APONF architecture:
http://tools.ietf.org/id/draft-zhou-aponf-architecture-00.txt
 
Your comments on the APONF BOF, and on the Internet drafts listed above are very much appreciated!
 
Best regards,
Georgios Karagiannis
