Hi Shilpa,

I think we should stick to the 22:00 UTC time for tonight's meeting (just under three hours from now), as it is the one that the majority of us have agreed on. It's a shame that you cannot attend. Perhaps you could reply to the summary email after the meeting to share any thoughts you might have?

Please find my comments below.

Subject: Re: [Mira-development] GPB and n/w transfer protocol

Hi Shilpa,

Option 3 looks like a good choice to me. It replicates the structure of the mainstream network protocols.

In IPv4, the header includes a 'total length' field which defines the total size of both the header and the message. With regard to Mira's network protocol, do you think it would be better for the length stated in the header to be the total size, rather than just the size of the message? This would allow us to extend the scope of the header (by, for example, including checksums of the header and the message in a new 'checksum' field in the header) without difficulty at a later date. Just a thought.

I belive IP4 header has two length fields. 4-bit header length and 16-bit total length. IP4 has variable-length header, so it need both header and total length of IP datagram to calculate where actually the data protion starts. In mira we have 16-bit fixed-length header and only information header has is the length of the data/message. To keep it simple I am first, just sending header and then I am sending the message.That way receiver know how may bytes to read from the stream. It is little inefficient but can be a good start to encarporate GPB.

Thank you for the clarification. That makes sense to me.

Also, I'd be very interested to see the messages using GPB that you've already implemented. Are you going to set up a new branch for this on Launchpad?

I am on vacation for whole month of July. I will try to upload the code to separate branch before I leave.

Thank you. I look forward to testing it.

Best regards,

Max
