Traffic Squeezer is a Linux kernel based WAN network traffic accelerator from Doublefish Solutions. It uses methods such as traffic compression, traffic PDU coalescing, protocol specific acceleration (such as TCP acceleration mechanisms), and quality of service. Traffic Squeezer also contains custom L7filters (application protocol filters), DPI (Deep Packet Engines) and so on to control and administrate your traffic. With Traffic Squeezer, you can optimize MPLS,ISDN, leased links, Satellite Networks, and Marine Internet, and even build your own custom WAN Appliance with Traffic Squeezer. A GUI is now supported via Doublefish Solution Aquarium. Aquarium is a Web-GUI that also supports Traffic Squeezer, Squid, and other open source solutions.
StructObject is a PHP class which can be used to create objects from a list of strict type variables. It takes a string with the names of types of variables that the current object should have. It only allows setting such variables to values of the specified types. The variables may not be unset.
Data Validator is a class to validate a set of values based on a list of rules. It supports the following validation orders: sequence (fields validated sequentially), all-at-once, and both (using a dependencies model). It can embed different user-defined validation rules libraries (a default built-in library is provided).
PHP common data gateway sets and gets values of common data structures. It provides static functions which can be called from anywhere to set up a common data structure with a name and values for named properties. A data structure is created if one does not exist with the given name. Properties may be changed to a given value specifying a string with the name of the data structure followed by the name of the property, separated by a dot. If no value is passed, the current value of the property is returned.
