[c-nsp] VegasPM process on WS-C3550-24

[William]

Hi,

I have a WS-C3550-24 running IOS 12.1(12c)EA1
(c3550-i5q3l2-mz.121-12c.ea1.bin), I've noticed this process is always
running when I run a "show proc cpu":

-SNIP-
  32   187547816  23444097       7999  9.33%  9.28%  9.31%   0 VegasPM
-SNIP-

Can anyone explain to me what this process does and should I be
concerned about it? I had a root around Google but was unable to find
any information so far.

The switch does L2/3 for a medium network (4 switches in total), one
EIGRP process does routing on a Routed port to an MPLS cloud.

Thank you for your time.

Regards,

Will
