Re: [Forces-protocol] Presentation of the options for LFB-level multicast]

Hi Robert,

Just one tiny point. I still cannot see the vital difference between the Merged mcast and Split mcast. Do you mean the main difference is the Merged mcast is for LFB class mcast while the Split mcast is for LFB Instance ID mcast only?  If possible, I think adding some more to explain (or define) the m1 and i1 may help more or less, especially to indicate if m1 is for LFB class and LFB instance, while il is only for LFB instance IDs. 

Cheers,
Weiming

  Hi All,
  I haven't seen any message on ForCES in the last 2 days, so I smell sth fishy. I post again my presentation here.

All,

Attached is a short presentation for the next IETF that summarizes the 
three options for LFB-level multicast:
- merged (among the current proposal in the draft),
- split (among the current proposals in the draft, called VPN, and 
Zsolt's proposal),
-  xcat (Weiming's proposal).

Also, there is a slide with the issue Jamal raised about unnecessarily 
repeating the class ID for commands destined to LFBs of the same class. 
Personally, I think the overhead is minimal. Maybe your view is different ?

Please review the slides and let me know if you have comments/suggestions.

Depending on the chosen solution(s), we may have to define a TLV for the 
LFB Instance ID, as this can be a normal ID, a virtual ID (MIID), a 
list, or a range.
