 Stream ID generation follows general guidelines for [HTTP/2](https://tools.ietf.org/html/rfc7540) with respect
 to odd/even values. In other words, a client MUST generate odd Stream IDs and a server MUST generate even Stream IDs.
 
+Stream IDs on the client MUST start at 1 and increment by 2 sequentially, such as 1, 3, 5, 7, etc.

+Stream IDs on the server MUST start at 2 and increment by 2 sequentially, such as 2, 4, 6, 8, etc.

 #### Lifetime
 
 Stream IDs MUST be used for only one stream per connection without re-use. Once the max Stream ID has been used (2^31-1), no new streams can be created, thus a new connection MUST be established to create new streams once the max has been met.
