DSI Development Package for Linux - Release Notes Release 6.5.1

2.15 RSI - IPv6 Support

This release adds support for connections between RSI clients and servers

over IPv6 networks and for the destination address to be specified as a

hostname.

Configuration of an IPv6 link is achieved via the updated rsicmd utility which

now accepts an IPv6 address (or hostname) on the command line.

For a server connection, the IP address parameter is currently ignored and a

socket is opened to allow a connection on the specified port via the hosts

IPv4 or IPv6 address.

For a client connection, the IP address parameter should either be an IPv4

address (in a.b.c.d format), an IPv6 address (in abcd:1234::5678 format as

per RFC5952) or a hostname (eg rsihost.example).

In the case of a hostname which resolves to multiple IP addresses (both IPv4

and IPv6), RSI will resolve the name once and will then attempt to connect to

the server (over an IPv4 or IPv6 connection as appropriate) to each resolved

address in turn until a connection is made.

3 Other Changes

3.1 Software Installation

Two changes have been made relating to software installation to remove

inconsistencies in directory naming conventions:

The rpm UPD install path is now /opt/DSIUPD (previously /opt/dpkupd).

The shared library installation directories are now /opt/DSI/32 and

/opt/DSI/64 (previously /opt/DSI/lib32 and /opt/DSI/lib64 respectively).

3.2 SS7LD Device Driver

The SS7LD signaling board device driver has been updated to remove a

potential start up issue due to invalid host PCI bus access.

3.3 ssdm – HSL Link Congestion (IPY00100380)

This release corrects an issue which limited (to 2,000) the maximum number

of outstanding (unacknowledged) octets on an HSL link. As a result, links with

high latency may have experienced link congestion and reduced throughput.

3.4 ssdm – Low Speed Link Resource Exhaustion

This release corrects a problem that on the SS7MD board could lead to links

entering a failed unrecoverable state as a result of receiving high traffic load

in conjunction with a high number of configured links (eg 124).
