call#1 minutes



Quick minutes and the slides I used attached. Note that I added one more slide to list all function combination without any network drawn into the picture.


Start:
	~8AM PST - ~8:46AM PST

Present (sorry if I missed someone or mistyped the name):
	Pedro Batista
	Jouni Korhonen
	Bomin Li
	Peter Turnbull
	Philippe Sherier
	Steinar Bjoernstad
	Zakaria Tayq
	Kevin Bross
	Peter Ashwood-Smith
	Satory Matsushima

Discussion:
	The call concentrated on agreeing the baseline and assumptions for
	the CPRI mapper and RoE encapsulation/decapsulation functions
	and their placement in the system.	

	The attached powerpoint concludes the combinations for functions.
	It should be noted that the mapper also contains the RoE encap/decap
	function. However, the RoE encap/decap can be deployed as standalone
	function (assume that RE and/or REC are the "native" RoE compliant
	devices).

	The mapper & encap/decap functions can be part of the switch,
	RE, REC or be standalone frontends or "sidecards".

	We aim to define 1:1 translation between CPRI frame format and
	native RoE encapsulation.

	CPRI rates 1 to 7 are of interest (because the use 8B/10B line
	coding).
	
Next steps:

	* Look into the RoE header itself.
	* Agree on the basics for the AxC to RoE flow mapping e.g. only
	   one AxC per Ethernet packet etc.
	* Agree RoE encapsulated packet properties e.g. whether the 
	   payload always has static size (after the flow/link has been
	   established) etc. 
	* Study how CPRI rates affect RoE encapsulated packet sizes..


	Contributions are welcome.. I'll send out the next agenda next week.
