[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Draft minutes of the FCIP teleconference, 8/22/01
1) Administrative work
All minutes will now be posted on the ips reflector.
The PDF supporting documents will be posted on the web-site
www.t11.org referenced to the FC-BB-2 project.
2) Discussion of security
The Aboba document is apparently the principal choice for
iSCSI security. Larry will post the document to the authors.
The iSCSI approach is to actually include ULP level
security. Our approach has been to use traditional
IPSec level security underneath TCP/IP.
3) FCIP_DE to FC Entity communication requirements
Murali has provided a document that lists all the
possible communications that may need to take place
between the FCIP entity and the FC entity. This would
logically be in Annex D. These are reminders about
the communications that need to be performed, but they
are not specifications of the communications. These
are not interoperability points.
a) 6.6.2.2 Notification by FCIP_DE that packets are discarded.
(accepted) It was noted that these are not
APIs. There may be one indication for
the discard of multiple frames in a vendor
specific manner.
b) 6.6.2.3 IP network transmit time cannot be determined.
(this line will be removed, and rewriting may
be needed)
c) 6.6.2.3 FC frame encapsulation does not contain a valid
time stamp.
(accepted)
d) 6.6.2.3 Synchronized time value is not well synchronized.
(accepted)
e) 7 Maintaining synchronized time value
(tells FCIP Entity not to stuff time value)
(accepted)
f) 7 Unreliable time value is corrected
(tells FCIP Entity to stuff time value)
(accepted)
g) 8.1.2 Request creation of TCP connection
(accepted)
h) 8.1.2 Creation is rejected
(accepted)
i) 8.1.2 Creation of second connection is accepted
(accepted)
j) 8.1.3 Dynamic creation of new connection
(accepted (4 items))
k) 8.1.4 Processing of TCP Connect requests
(accepted) This one is already contained and
needs to be modified in the table.
l) 8.4 FC entity uses FC Flow control (accepted)
m) 8.4 FCIP entity uses TCP Flow control (accepted)
Note that these may need some internal flow
control mechanisms. These are not specifically
defined, but these are not interoperability
points.
n) 10.1 Multiple TCP Connections within an FCIP_LEP
(accepted)
Murali noted that none of these are related to Fibre Channel.
The distinction is not useful for implementation purposes.
I don't think it will be a constructive exercise to try
to move the boundaries. One of the two documents will know
more about the other. At present, FC-BB-2 must be cognizant
of the FCIP entity's behavior. There was some work on
this in Hawaii at the FC-BB-2 meeting. Murali will study
this possibility. Routing is part of the issue.
4) Discussion of security
Don Fraser has started a discussion about some nits on the
security stuff.
5) Discussion of time server
The FC fabric time server is an SNTP type time server.
It was asked whether we should be using the IP or FC
time server. It was noted that the SNTP IP time server
may or may not exist.
6) 8.1.4 problem
The acceptance of a connection. The FCIP entity creates
an FCIP_DE when a new connection is made. This text is
already included, and Murali accepted the resolution.
Ralph indicated that an additional sentence was required to
take care of this.
7) B_Port definitions
Can B_Ports get time services? B_Ports really only work
in constrained configurations where generic management is
not required.
8) SAN island interconnections
Two SAN islands joined by a link may not be notified
if the link fails. The notification process needs to
be included from the FCIP to the FC Entity. FC procedures
should be successful in recovering. A LSR needs to be
generated. Note that loss of signal is not necessarily
a symptom of a loss of TCP/IP continuity. HELLO timers
may be the ultimate catcher for this. The longest latency
between connections is on the order of 300 msec with satellites.
9) Next week's meeting
Power will be provided
Computer projectors will be provided
Vi will provide an overhead projector
The MIB meeting will be arranged for Monday evening.
The next teleconference will be scheduled at the interim
meeting next week.
ACTION ITEMS:
1) Murali will study the possibility of modifying the
boundary between FC and FCIP entities with a view toward
simplifying the structure. There is some skepticism that
this will turn out helpful.
2) Ralph will add the correction required to 8.1.4.
