Isode's Icon PEP 1.1 release is a Fully Supported Isode release of Icon PEP (see the Supported Releases page for more details).

Listed below are the major changes that Icon PEP 1.1 introduced.


Metrics Transmission

All Icon-PEP metrics can now be sent over protocol to the Icon-5066 management process in addition to being saved on disk and displayed by the built in monitoring UI. This capability enables a planned Web monitoring UI for Icon-PEP, which will be integrated with the Icon-5066 management UI.

Parsing DNS Protocol and HTTP 1.0 Headers to Generate Metrics

This will facilitate monitoring web traffic.

SLEP Compression

Support for SIS Layer Extension Protocol (SLEP) (S5066-APP3) compression capability is added. This can be used with the HFFTP file transfer product (shipped with Icon-5066) and by the HF PEP capability offered by Icon-PEP. This compression is recommended and is expected to deliver performance benefits for Web browsing which is a key application target of Icon-PEP.

TCP Connection Limit

The number of PEP TCP connections can be limited. This is important to prevent overload.

IPv6 Support Added

IPv6 support has been added for both the IP Client following the specification of STANAG 5066 Ed4 Annex U as well as TCP traffic supported by Icon-PEP.

NAT (Network Address Translation) Support

This enables a shore-based Icon-PEP to handle traffic from any mobile unit that is able to connect to it, without needing the IP routing to be configured in advance. This gives mobile units the flexibility to switch shore stations quickly in response to changing conditions or location. This works as a proxy and IP traffic (UDP, TCP, ICMP Ping) is sent from Icon-PEP directly. This simplified shore-based configuration and enables operation without a GRE tunnel to an associated IP router, which is not needed when there is no requirement for traffic initiated from shore.

Icon-Topo Support

This allows a mobile unit deployment to switch the STANAG 5066 address of the shore station to support mobility of TCP connections and Web browsing initiated on a mobile unit.
