Hi Sudhin,



At the last BMWG meeting, Warren sent your draft [0] back to the working group for proof reading.



There are a couple of ways we can proceed.



I suggest that generous WG participants spend a little time with individual sections, so that we can share the load. I have tackled Sections 1 and 2 below.



Also, there are some on-line tools that can help you, while you are waiting for other reviewers.



Scribens:  https://www.scribens.com/mobile.html

This works better if your text does not have line breaks before a sentence ends (like the text version of our Internet Drafts). Red and yellow suggestions are more important.



Paperrater: https://www.paperrater.com/proofreader/proof_results?ticket=459bfb354122245ccaff79c5f

This one provided more general help than actual suggestions, and it failed to highlight some suggestions on my screen after pasting the file in a window for analysis.



https://virtualwritingtutor.com/

I didn't find this output complete or very helpful.



That's it, Try to extend what I've suggested to other parts of your draft, and hope for more BMWG'ers to help-out with a section or two.

(as a participant)

Intro: As several of have pointed-out, there are no spaces after the end of many sentences. It seems that your editing tool is hiding these from you - you need to look at the text output on the IETF site and you will find them easily.

Single-Active Redundancy Mode: When only a single PE, among all the
PEs attached to an Ethernet segment, is allowed to forward traffic
to/from that Ethernet segment for a given VLAN, then the Ethernet
segment is defined to be operating in Single-Active redundancy mode.

2. Test Topology


OLD
There are five routers in the Test setup.SHPE3, RR/P, MHPE1 and
MHPE2 emulating a service provider network.CE is a customer device
connected to MHPE1 and MHPE2, it is configured with bridge domains in
multiple vlans. The traffic generator is connected to CE and
SHPE3.The MHPE1 acts as DUT.The traffic generator will be used as
sender and receiver of traffic.The DUT will be the reference point
for all the test cases. MHPE1 and MHPE2 are mulihome routers
connected to CE running single active mode.The traffic generator
will be generating traffic at 10% of the line rate.
