The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] [mpls] Operator survey on LDP deployments
Operators,
We need to produce a "description of operational experience"
report to accompany the LDP spec to the IESG.
Rajiv Papneja suggested to formalize this in a questionnaire. Rajiv and
I put together a set of questions, with input from Halit Ustundag,
Bob Thomas and Loa Andersson.
Please take a few minutes to fill out the survey (at the end of
this email and also attached). Partial responses are also useful, if
you can't/don't_want_to answer any of the questions, just skip to the
next one.
If you would like to respond anonymously, please state so in the
questionnaire. Confidential responses may be sent to Scott Bradner at
sob@harvard.edu. Scott will strip away the info that would make it
possible to trace the respondee before forwarding us the responses.
Scott has acted in this role for other similar efforts.
In addition, all confidential responses will be summarized in the
final report, to further obscure the source. Many thanks to Scott for
his help.
Please send your responses by Oct 31st.
Thank you for your cooperation,
Ina & Rajiv
Feedback on LDP deployments
============================
1) Contact for the information provided
Name:
Title:
E-mail:
Organization/department:
Postal address:
Phone:
2) Confidentiality
-- I would like the information to be confidential (confidential
responses will be summarized)
-- This information can be made publicly available
3) Reason for running LDP in the network (check all that apply)
-- L3VPN
-- L3VPN inter-AS scenario
-- L2VPN
-- VPLS
-- pseudowires
-- label-based forwarding
-- other (please specify)
4) Sections of the deployed network where LDP is enabled
-- edge
-- core
-- edge and core
5) How long have you run LDP in the network for (how long ago did you
start using LDP).
6) Reason why LDP was selected
-- ease of configuration
-- no need for traffic engineering
-- scalability concerns with other protocols
-- use of a particular offline computation tool
-- equipment vendor only supports LDP
-- ease of management
-- interoperability concerns
-- better understanding by staff
-- other
7) Are there targeted LDP sessions? If yes, for what purpose?
-- traversing a traffic engineered core
-- pseudo-wires
-- other (please specify)
-- don't use targeted sessions
8) Number of LSR running LDP in the network
9) Maximum number of sessions per LSR
10) Average number of sessions per LSR
11) Average number of targeted sessions per LSR
12) Number of LDP adjacencies per session (how many parallel interfaces
connect two peers - one or more than one)
13) Number of incoming/outgoing bindings (average)
14) Number of LDP routes installed
15) Number of PEs in the network
16) Do you use LDP graceful restart?
17) LSP setup is accomplished with
-- independent control
-- ordered control
-- both (if some routers support one and some support the other)
-- don't know
18) Label distribution is
-- downstream unsolicited mode
-- downstream on demand mode
-- don't know
19) If downstream on demand mode is used, is loop detection configured?
20) Label retention mode
-- conservative
-- liberal
-- both
-- don't know
21) Number of implementations in the network
-- one
-- more than one (please specify how many)
-- optional - please specify the implementations used
Operations
============
22) What challenges did you encounter in deploying an LDP network?
23) What issues did you encounter in running an LDP network?
24) Did you encounter any security issues with LDP?
Other
======
25) Did you face any common interoperability issues if multiple vendors
are used? If yes, please list.
26) Please comment on your experience with the protocol (e.g. resilience
to failures, convergence times, silent failures, etc.)
