• feedback on Tsvart

[ahuangfeng]

Tsvart todo:

• How long should fragments be stored before they are discarded. That should be stated.
• I wonder how the sender side knows, what the receiver is able to process. It might make sense to exchange this information at the beginning of the communication.
• Section 4.1
  The length field in the UDP header is limited to 65535 bytes, therefore the
  UDP payload is limited to 65535 - 8 bytes, which is 65527 bytes. This is smaller
  than stated in the first sentence. In addition to that, when using IPv4, the size
  is even 20 bytes smaller, since the IPv6 header contains a 16-bit field holding
  the total length of the IPv4 packet.
• Section 4.2
  What should happen if the Private Encoding Option is present, but the S-bit is
  not set? What should happen if the S-bit is set, but the Private Encoding Option
  is not present?

• Check consistency between the YANG module imports (generic udp-client grouping) and the examples shown in the apendix (namespace wise)
