Cisco, Citrix, Crescendo Networks, F5 Networks, Foundry and Juniper 6家公司的
executives一起吃个饭，基本反应了未来一段时间的市场格局以及走向了。
Application acceleration, application security, application reliability应该就
是未来一段时间application networking的主要方向了。

XML acceleration not only means to accelerate time-consuming tasks like
XSL transformations(XSLT) and schema validation, but also
security-related features like encryption and filtering. Say we've got
XML acceleration appliance, we use it to shed portions of XML processing
from application, which helps back-end application server a lot.
For example, the appliance can respond to SOAP messages, probably through
HTTP (SOAP can operate on almost any transport, but XML accelerators
need to limit thei

不是需要压缩，解压缩，可对于网络设备来说，就不那么好办了

application performace mgmt is not an easy task, i don't think
HP is a good choice.
just read this part:
"For those of you keeping score, we at Cisco have increasingly been talking
about the role the network plays in the grand world of applications, and
blanketing our website, press releases, powerpoints, partners’ in-boxes, etc.
with a new set of Cisco acronyms."
"blanketing" isn't that grand? some tech writer they hire for this gig. lol

cisco's AON sucks, esp. their stupid written-in-java software pack. f**king
slow and lack of features...

why telephone services only?

what are the criteria for xml application classification? I think acceleration
is the goal, but the key point is how to classify the application. The
traditional layer 7 switch can classify the traffic based on the layer 3/4 and
the application(layer7) header, but not very deep packet inspection, if xml
routing/acceleration moves onto DPI and content basis, there would be huge
challenge, right?

consideration.

像OpenDocument format那样压缩不行吗？Openoffice的native格式就是简单的
压缩过的xml吧？

just kidding. :) it works like the telephone network -- putting
lots of "intelligence" into the network. I suppose this is not
for free? hehe. big depature from the original Internet's E2E
design.

xml has binary format. most appliance
vendors convert the traffic into binary format by using their software
stacks or hardware, and do other XSLT stuff, taht's called acceleration.
Some hardware processing units operate at 1g wire speed, which means
they can process xml traffic at giga-bit/sec.
