If you use Builder.mergeFrom() and catch the exception, the builder will be left containing whatever data was parsed before the problem was detected.
However, a better solution would be to encode your data in multiple messages, such that each packet you send contains one message. That way, if one packet is lost, it doesn't prevent you from parsing previous or subsequent packets. You can also receive packets out-of-order.
