here is an article regarding some differences between them:
Nicolas Droux' Blog
so fugitive is basically right. link aggregration is the act of basically taking multiple ethernet cables and trunking them together to increase the link speed beyond the limits of any one single cable or port, and to increase the redundancy for higher availability. at my shop, we do this to the same switch to increase our copper backup network speed (1 cat6 line to 2 cat6 lines, thus allowing for 2 gig limit). we use a juniper ex4200 that already comes more or less out of the box to do LA (although these switches i feel are a pain to deal with).
here is an article on how to work with dladm:
Solaris tip of the week: Link Aggregation and Logical Interfaces - greetings from network.com
as for ipmp, you are looking to run 2 ethernet cables to two seperate switches which gives you the HA situation but not just at the host, but the switch and essentially the router levels (if you have cross-connects between switches and routers).
for ipmp, check out this article:

Hi,
I need to setup a hacmp cluster (my first one, we usually use VCS on AIX), but I require more network bandwith than a normal gigabit etherchannel setup can provide, so I am thinking about using linkaggregation - 2 active adapters to one switch and a single backup adapter to another switch...

uri::url
URI::URL(3) User Contributed Perl Documentation URI::URL(3)
NAME
URI::URL - Uniform Resource Locators
SYNOPSIS
$u1 = URI::URL->new($str, $base);
$u2 = $u1->abs;
DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to
be distributed with the libwww-perl library.
The following differences exist compared to the "URI" class interface:
o The URI::URL module exports the url() function as an alternate constructor interface.
o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase".
o The URI::URL->newlocal class method is the same as URI::file->new_abs.
o URI::URL::strict(1)
o $url->print_on method
o $url->crack method
o $url->full_path: same as ($uri->abs_path || "/")
o $url->netloc: same as $uri->authority
o $url->epath, $url->equery: same as $uri->path, $uri->query
o $url->path and $url->query pass unescaped strings.
o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters)
o $url->params and $url->eparams methods
o $url->base method. See URI::WithBase.
o $url->abs and $url->rel have an optional $base argument. See URI::WithBase.
o $url->frag: same as $uri->fragment
o $url->keywords: same as $uri->query_keywords
o $url->localpath and friends map to $uri->file.
o $url->address and $url->encoded822addr: same as $uri->to for mailto URI
o $url->groupart method for news URI
o $url->article: same as $uri->message
