SA[15:0] address identifying the VC Table Record for the
candidate connection. If "Left Leaf" is a logic zero, "Left
Branch" contains the SA[15:0] value pointing to another
Secondary Search Table entry.
If the Search Table entry is part of a multicast linked list, the
Left Branch is the VC Table address of one VC in the
multicast.
Right Leaf
This flag indicates if this node is a leaf. If "Right Leaf" is a
logic one, the Right branch is a leaf and the binary search
terminates if the decision bit is a logic zero. If "Right Leaf" is
a logic zero, "Right Branch" value points to another node in
the binary tree.
If the VC pointed to by the Left Branch belongs to a multicast
set, the Right_Leaf value is arbitrary, but it is recommended
to be set to a logic 0 for future compatibility.
Right Branch
The pointer to the node accessed if the decision bit is a logic
zero. If "Right Leaf" is a logic one, "Right Branch" contains
the SA[15:0] address identifying the VC Table Record for the
candidate connection. If "Right Leaf" is a logic zero, "Right
Branch" contains the SA[15:0] value pointing to another
Secondary Search Table entry.
If the Search Table entry is part of a multicast linked list
(except the last element of the list), the Right Branch is the
Search Table address of the next element in the list. If the
Search Table entry is the last element in the linked list, this
field is arbitrary.
The above encoding defines the binary search tree recursively.
The following special cases must be respected:
1. A binary tree with only one connection must have both the Left and Right
Branches pointing to the solitary VC Table Record. Both Leaf flags must be a
logic one.
