DS Architecture Concepts in March 2015 IEEE Document

Delve into advanced DS architecture concepts discussed in the March 2015 IEEE document by Mark Hamilton from Spectralink. The document elaborates on the basic DS model, terminology like Portal DSAF, MAC service tuples, and distributed brains, offering insights into network structures and protocols. Discover how the DS framework operates and distributes MAC services, providing a comprehensive understanding for networking enthusiasts.

1. March 2015 doc.: IEEE 11-15/0454r0 Some more DS architecture concepts Date: 2015-03-12 Authors: Name Mark Hamilton Affiliations Address Spectralink Phone +1-303-441-7553 email mark.hamilton@spectralin k.com 2560 55th St, Boulder, CO, 80301 Sli de 1 Submission Slide 1 , Mark Hamilton, Spectralink

2. March 2015 doc.: IEEE 11-15/0454r0 Abstract Building upon the concepts in 11-14/0562, this discusses more DS concepts. Sli de 2 Submission Slide 2 , Mark Hamilton, Spectralink

3. March 2015 doc.: IEEE 11-15/0454r0 Recall our basic model of the DS. Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY DS The DS has three users, two APs and a portal, so is shown passing behind a MAC. The DS can be implement with anything in any wayyou d like. The only requirement is to meet the behaviors and constraints externally visible (and even that is only a logical) view. Submission Slide 3 , Mark Hamilton, Spectralink

4. March 2015 doc.: IEEE 11-15/0454r0 Terminology: Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY DS The DS has brains, and distributes MAC service tuples - Brains: Knowing what non-AP STAs are associated to which AP - MAC service tuple : the collection of an MSDU and the goop (source address, destination addresses, priority and service class) associated with it. Submission Slide 4 , Mark Hamilton, Spectralink

5. March 2015 doc.: IEEE 11-15/0454r0 For example, a fat yellow cable Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.3 802.3 802.3 802.3 10BASE5 DSAF s and the Portal each have need for a piece of a distributed brain (shown here as a little green box) Distributed brains require green box to green box protocol updating a distributed database (in effect) Submission Slide 5 , Mark Hamilton, Spectralink

6. March 2015 doc.: IEEE 11-15/0454r0 For example, a fat yellow cable (cont.) Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.3 802.3 802.3 802.3 10BASE5 Little green boxes have to distribute MAC service tuples around, also. Probably done by encapsulating each MAC service tuple in a green box to green box frame So, the 10BASE5 network just sees a network of little green boxes Submission Slide 6 , Mark Hamilton, Spectralink

7. March 2015 doc.: IEEE 11-15/0454r0 Of course, can be a modern 802.3 network Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.3 802.3 802.3 802.3 802.3 network still just sees a network of little green boxes Submission Slide 7 , Mark Hamilton, Spectralink

8. March 2015 doc.: IEEE 11-15/0454r0 Of course, can be a modern 802.3 network Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.3 802.3 802.3 802.3 802.3 network still just sees a network of little green boxes Submission Slide 8 , Mark Hamilton, Spectralink

9. March 2015 doc.: IEEE 11-15/0454r0 Or, it can be a full network, IP, routers, Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.3 802.3 802.3 802.3 It s still just a network of little green boxes (that find each other Submission somehow) Slide 9 , Mark Hamilton, Spectralink

10. March 2015 doc.: IEEE 11-15/0454r0 Or (of course), an 802.1Q Bridged LAN Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.x 802.x 802.x 802.x Bridge Bridge But still just a network of little green boxes (that find each other somehow) Submission Slide 10 , Mark Hamilton, Spectralink

11. March 2015 Now, let the Bridged LAN help with the brains! doc.: IEEE 11-15/0454r0 Portal DSAF DSAF DSAF MAC PHY MAC PHY MAC PHY 802.x 802.x 802.x 802.x Bridge Bridge Bridges already have some understanding of what is attached to network via which bridge port . Let s reuse it! Submission Slide 11 , Mark Hamilton, Spectralink
