Payload [variable size]

• In the payload ?eld the parameters are carried.
  Parameter被攜帶于Payload字段中 。
• The size of the SOME/IP payload ?eld depends on the transport protocol used. With UDP the SOME/IP payload shall be between 0 and 1400 Bytes. The limitation to 1400 Bytes is needed in order to allow for future changes to protocol stack (e.g. changing to IPv6 or adding security means). Since TCP supports segmentation of payloads, larger sizes are automatically supported.
  SOME / IP payload字段的大小取決于使用的傳輸協議。 對于UDP，SOME / IP有效載荷應該在0到1400字節之間。限制為1400字節是為了允許將來對協議棧進行更改（例如更改為IPv6或添加安全機制）。 由于TCP支持有效載荷的分段，所以自動支持更大的尺寸。
