Question regarding null padding session name in RSVP-TE Att obj

    I have a simple question regarding null padding to the session name to make it to be a multiple of 4 and at least 8 in RSVP-TE attribute object. It is really appreciated if someone can help to clarify it. Thanks in advance.

If the string length is exactly a multiple of 4 and greater than 8 without counting null padding or null terminate character, --
1) is it required to add at least null terminated char to indicate the string termination?
2) is it required to check at the receiver whether the session name is null terminated or not?

The contents of the Session Name field are a string, typically of display-able characters.  The Length MUST always be a multiple of 4 and MUST be at least 8.  For an object length that is not a multiple of 4, the object is padded with trailing NULL characters.  The Name Length field contains the actual string length.
