The second octet of the TLV is the length field,
interpreted as an unsigned integer, indicating the number of
octets of the value that follows the length. A length of
zero indicates that there is no value
(i.e., the gate operation has no parameters).
The third through (3 + length -1)th octets encode the
parameters of the gate operation, in the order that they
appear in the definition of the operation
in Table 8-4. Three parameter types are defined:
- StreamGateState:
A GateState parameter is encoded in a single octet, and
is interpreted as an integer value.
The value 1 indicates open; the value 2 indicates closed.
- IPV:
An IPV is encoded in four octets as a 32-bit
signed integer. A negative denotes the null value;
zero or positive values denote internal priority values.
- TimeInterval:
A TimeInterval is encoded in 4 octets as a 32-bit
unsigned integer, representing a number of nanoseconds.
The first octet encodes the most significant 8 bits of the
integer, and the fourth octet encodes the least
significant 8 bits.
- IntervalOctetMax:
An integer representing the maximum number of MSDU octets
that are permitted to pas the gate during the specified
TimeInterval. If this parameter is omitted, there is
no maximum.
