[Sis-csi] comments on cislunar doc

[Marc Blanchet]

Keith,
  as discussed this morning, here are some comments on the doc:

1.4 References
add IPv6:
[RFC2460] Internet Protocol, Version 6 (IPv6) Specification. S.  
Deering, R. Hinden. December 1998.

At the end of 4.4.2, something along the lines of:
Using IPv4, the path between any two nodes, ground or space, might  
cross networks using the same private address space (10.x.x.x), which  
means a possible number of Network Address Translation (NAT) in the  
path. NAT translates the addresses in the header and for some  
protocols inside the payload. NAT breaks the end-to-end reachability,  
breaks some protocols which carry IP addresses in their payload and  
makes security more difficult to apply on the IP header. Careful  
deployment should be designed if IPv4 is used as the network IP  
protocol.

pretty minor:
- (in my version of word), header in the first pages (such as TOC) is  
"CCSDS REPORT - SOIF TRANSPORT LAYER".
- (in my version of word), 4th paragraph of 3.6 does not finish.
- section 4.5, last sentence: 1-2 bytes out of 1500 is 0.1%. So I  
would suggest: "For full-sized ..., overhead of around 0.1%".
- section 4.6.3.4: s/tunnel ,/tunnel, /
- section 4.8.2: s/bytstream/bytestream/
- section 4.8.2: s/implemeneted/implemented/
- section 5.1.1.2: line 2: should the Figure be 7-2?
- section 6: s/Secion 2/Section 2/
- section 7: s/destination will very/destination will be very/
