Wireless Mesh Networks 12/1/2018 doc.: IEEE 802.11-04/0013r0 March 2004 Process Considerations Helpful for Maintaining Extensibility of ESS Mesh Kue Wong jkwong@nortelnetworks.com Wireless Mesh Networks Nortel Networks Kue Wong - Nortel Networks Realtek

Overview Nortel Networks supports the ESS Mesh Standards effort March 2004 Overview Nortel Networks supports the ESS Mesh Standards effort Mesh networks means many things I.e. it solves many different problems Concern that standard may freeze pre-maturely a still rapidly developing solution space Suggestions as to how TG process may be used to help maintain extensibility of resulting standard Kue Wong - Nortel Networks

Diverse Problem and Solution Space March 2004 Diverse Problem and Solution Space Two use-cases to illustrate : Dynamic: NRL Problem: continually mobile wireless distribution system Solution: Dynamic Backbone Subnet (DBS) 11-03-236r0-WNG-Tutorial_Dynamic_Backbone_Subnet.ppt Static: Problem: setup and autoconfigure a fixed wireless distribution system 11-03-0712-01-0wng-performance-802-11-home-network-mesh-testbed.ppt Solution: maybe a simple extension of 802.1D suffices here 11-03-0867-00-0wng-ess-mesh-network-interconnection-considerations.ppt Many other dimensions in situations and goals encountered E.g. Goals: optimize for path redundancy, single path thruput, overall subnet thruput, etc. Single solution premature or unlikely 11-04-0045-00-0mes-scope-and-interconnectivity-consideration-ess-mesh.ppt Kue Wong - Nortel Networks

Suggestion Consider the space of mesh network applications March 2004 Suggestion Consider the space of mesh network applications Explore thoroughly Make a considered call on the high runner representative cases Consider proposals for these Make sure that the final ESS Mesh Standard allows for extension/optimization to these cases and proposals Kue Wong - Nortel Networks

March 2004 Final Comment Quote from PAR (11-04-0054-02-0mes-par-ieee-802-11-ess-mesh.doc): “…. shall enable interoperable formation and operation of an ESS Mesh, but shall be extensible to allow for alternative path selection metrics and/or protocols based on application requirements. …..” May be difficult to achieve without suitable process in place Kue Wong - Nortel Networks
