4. Optionally, type a TTL value for IP multicasting in the Multicast TTL box.
By default, SMART Sync multicast packets are sent with a TTL value of 1, which
prevents them from being forwarded beyond a single subnetwork. Multicast
datagrams with a TTL of greater than 1 can deliver to more than one subnetwork (if
there are one or more multicast routers attached to the first-hop subnetwork).
Typical TTL thresholds are:
TTL Threshold Scope
1 Restricted to the same subnetwork
15 Restricted to the same site
63 Restricted to the same region
127 Worldwide
191 Worldwide; limited bandwidth
255 Unrestricted scope
5. Optionally, type the millisecond-per-chunk for TCP traffic in the TCP delay box.
