5. Summary of Changes: Mesh E2E Seq. No. & TTL
March 2007
doc.: IEEE /0389r0
March 2007
Summary of Changes: Mesh E2E Seq. No. & TTL
Mesh E2E Sequence Numbering
Specify the handling of Mesh E2E Seq. No. at source MPs.
Limit its usage for detecting duplicate frames only.
Removed texts for out-of-order delivery detection and reordering procedures.
TTL Field Initialization at Source MPs
Initialized to MIB value.
Added “dot11MeshTTL” to dot11MeshPointConfig TABLE in Annex D.

6. Summary of Changes: Broadcasting & Multicasting

doc.: IEEE /0389r0
March 2007
Summary of Changes: Broadcasting & Multicasting
Fix the behavior at destination MPs when the Address 3 field of incoming frames is set to a broadcast address.
Transmit the frames to all its peer MPs and, if any, proxied entities outside the boundary of the mesh after frame translation.
The reachability of broadcast frames are controlled by TTL values only (not by the existence or the lack of optional address fields).
Separate descriptions into those at source MPs and at intermediate/destination MPs (as in unicasting).
