4. ers As a result sizing message_size_max too close to the UDPv4 datagram size limit of 65535 bytes will result in messages too large for the DataWriter to send A new UDPv4 transport property protocol_overhead_max accounts for the pro tocol overhead as well as any other protocol related overhead it is set by default to account for UDPv4 and IPv4 headers Furthermore the middleware will automatically limit the effective message_size_max to be no larger than the UDPv4 limit 65535 minus this overhead More Flexibility in Allow Deny Interface Specification for UDPv 6 transport This release provides more flexibility in terms of filter specification for allowing or denying interfaces for the UDPv6 transport The new method is case insensitive and accepts addresses and patterns in IPv6 notation It also supports the wildcard character which can expand up to 4 digits in a block The wildcard must be either leading or trailing Multiple wildcards can be specified in a single filter but only one wildcard can be specified per block between colons Examples of valid filters Filter Same as Matches ea Any IPv6 interface fe80 FE80 Fe80 0 0 FE80 0000 0000 0000 0000 0000 xxxx xxxx Fe80 0 0 0 0 0 FE80 aBC 202 2 2 FE80 0ABC 0000 0000 0202 2xxx Xxxx xxx2 eth eth0 eth1 etc RTI Bug 14075 Ability to Configure EntityFactoryQosPolicy in DomainParticipantFactory u
