HaHa, funny man. :) From: Jakob Heitz (jheitz) [mailto:jheitz@cisco.com] Sent: Thursday, May 29, 2014 1:43 PM To: Eric Gray; Joel Halpern; Paul Quinn (paulq) Cc: sfc@ietf.org Subject: RE: Figures in draft-quinn-sfc-arch-05 Importance: High You could turn the whole picture right by 90 degrees. If you don't like top to bottom instead of left to right, make a note that it's in landscape. --Jakob From: sfc [mailto:sfc-bounces@ietf.org] On Behalf Of Eric Gray Sent: Thursday, May 29, 2014 8:31 AM To: Joel Halpern; Paul Quinn (paulq) Cc: sfc@ietf.org<mailto:sfc@ietf.org> Subject: [sfc] Figures in draft-quinn-sfc-arch-05 Paul/Joel, Pretty sure that Figures 5 and 6 don't actually fit the width expected for an Internet Draft (Figure 5 is more than 80 characters wide and Figure 6 is wider still). Depending on how a reader tries to read the draft, this can turn complicated illustrations into a _real_ fun time. :) Also, I am unsure what the figures are trying to convey with some of "dotted lines" crossing the service functions. If the intent is to show that a service function is a virtual instance hosted by some network device, perhaps this will be better shown in a separate figure and this aspect of Figures 5 and 6 can be eliminated? I would suggest replacing Figure 5 with a figure along the lines of: source +-----+ +-----+ | +-->| sf2 +--+ +-->| sf4 +--+ | | | | | | | | | | +------+--+ +-----+ +-->+-----+--+ +-----+ +->+-----+ | | sf1 | +-----+ | sf3 | +-----+ | sf5 | +->| +----->| sf2 +----->| |----->| sf4 +---->| |-+ | | | | | | | | | | | +------+--+ +-----+ +-->+-----+--+ +-----+ +->+-----+ | | +-----+ | | +-----+ | | +-->| sf2 +--+ +-->| sf4 +--+ +----+ | | | | | +-----+ +-----+ V destination Figure 5: Load Balancing (67 characters?) Similarly, I would suggest replacing Figure 6 with a figure along the lines of: source | +-----+-+ +-----+-+ +---+ +-->| sf2 |-|+ +-->| sf4 |-|+ | +---|-->| | || +------>| | || | +------+|---+ +-----+ |+-->+-----+|---+ +-----+ |+-->+-----+ | | sf1 || +-----+ +--->| sf3 || +-----+ +--->| sf5 | +-->| +|------>| sf2 |+---->| ||------>| sf4 |+---->| |--+ | | || +---->| |-+ | || +---->| |-+ | | | | +------+|-|-+ +-----+ |+-->+-----+|-|-+ +-----+ |+-->+-----+ | | | | | +-----+ || | | | +-----+ || | | +------++ | +-->| sf2 |-|+ +-----++ | +-->| sf4 |-|+ +-----+ | | | sf1' | | +-->| | +--->| sf3'| | +-->| | +--->| sf5'| | +-->| +--+ | +-----+----->| |--+ | +-----+----->| |--+ | | | | | | | | | +------+----+ +-----+----+ +-----+ | | +--------+ | V destination Figure 6: Load Balancing and HA (72 characters?) In both cases, the figure has all the same connection complexity (fixed up in a few places), but seems to be less busy. -- Eric
