摘要： Information is added to an encapsulated payload in a data field of a frame subsequently to placing a checksum into a checksum field of a header encapsulating the payload, wherein the checksum has been determined from byte values of the header and the payload, yet having the checksum remaining detectable as valid upon interpretation of the header and the payload. A signature field that contains the information is inserted into the data field. The signature field has a checksum cheater subfield. A one's complement of a checksum determined from byte values of the information is then placed into the checksum cheater subfield. Accordingly, the checksum in the checksum field of the header remains valid.

摘要： Embodiments of the invention are directed to evaluating the sequence of packets in a received packet stream. In some embodiments, when a packet in the packet stream is received, its sequence number may be determined and compared to an expected sequence number indicative of the highest received sequence number in the packet stream. If the sequence number of the packet is greater than or equal to the expected sequence number, the packet may be considered an in-order packet and a counter that counts the number of received in-order packets in the packet stream may be incremented.
