Modeling TCP Performance With Proxies | 2007-01-01 | University of Michigan |
| This paper investigates the TCP dynamics and performance over proxies that shorten the TCP feedback loop by segmenting the end-to-end connection. Such proxies are often used to improve TCP performance, e.g., a splitting/spoofing proxy in the satellite communication, and more commonly, a web cache. By analysis, the author's attempts to develop a basic understanding of the properties of TCP dynamics when such proxies are used, and further obtain certain design principles of systems involving such proxies. Simple models are presented capturing some features of the proxy performance in both the lossless and lossy scenarios.

Performance of Different Proxy Concepts in UMTS Networks | 2007-01-01 | University of Stuttgart |
| It is well known that the large round trip time and the highly variable delay in a cellular network may degrade the performance of TCP. Many concepts have been proposed to improve this situation, including Performance Enhancing Proxies (PEPs). One important class of PEPs are split connection proxies, which terminate a connection from a server in the Internet in a host close to the Radio Access Network (RAN) and establish a second connection towards the mobile User Equipment (UE). This connection splitting can be done either purely on the transport layer (TCP proxy) or on the application layer (HTTP proxy in the case of web traffic).

BPO Company Implements Solution for Improved Security and Increased Productivity | 0000-00-00 | Microsoft |
| Zenta Group (Zenta), rated one of the top 10 Business Process Outsourcing (BPO) companies by India's National Association of Software and Service Companies, has carefully selected its technology infrastructure to uphold its commitment to expected service levels, underscoring its emphasis on quality. Zenta must maintain 99.9 percent uptime, serving customers with virtually no circuit breakdown. To increase network security, provide faster Internet access, and improve IT administration, Zenta replaced its Linux-based proxy server with Microsoft Internet Security and Acceleration (ISA) Server 2004. This implementation has led to a reduction in workload by as much as 80 percent. Internet access has also improved by 30 percent.

Secure Remote and Outbound Internet Access Using ISA Server 2006 Web Proxy | 2006-06-01 | Microsoft |
| Almost all companies today have a connection to the Internet that provides access to information on Web servers at partner and customer sites, as well as access to Web content at main offices from branch locations. A popular and powerful solution to the problems of secure Web access is a Web proxy. Web proxy devices help enable a company to control the flow of information moving over Web channels using the HyperText Transfer Protocol (HTTP), Secure HTTP (HTTPS), and File Transfer Protocol (FTP) application protocols. Web proxy servers act as intermediaries between client and server. This white paper explores how ISA Server 2006 provides enhanced security and application acceleration by acting as both forward and reverse Web proxy for the corporate network.

How to Gain Visibility and Control of Encrypted SSL Web Sessions | 2006-04-23 | Blue Coat Systems |
| SSL traffic is growing into a significant amount of enterprise network traffic. IT is unable to secure, control, or accelerate this traffic. Blue Coat's new SSL proxy removes IT's blinders, enabling organizations to establish a critical control point for policy, performance, and protection of users and applications using SSL. While enterprises should update acceptable use policies, Blue Coat's solution affords the appropriate flexibility and controls to mitigate any potential privacy concerns within the enterprise.

A Simple Guide to Creating a Firewall and Squid Proxy Server | 2005-12-01 | Red Hat |
| A firewall is extremely important in any environment where systems will be connecting to an insecure network like the Internet. It can also be used to prevent certain types of traffic from leaving a company network. Red Hat Enterprise Linux utilizes the iptables system, which is a kernel-level packet-filtering tool. This paper will show how to set up simple forwarding and filtering rules for a firewall appliance. This paper will cover the configuration and setup of a firewall and squid proxy server. By no means is this meant to be a complete solution; it is a straight forward example of how to get started.

Implementing Reverse Proxy in Squid - A White Paper | 2002-02-02 | BMC Software |
| This paper describes reverse proxies, and how they are used to improve Web server performance. The paper gives an introduction to reverse proxies, describing what they are and what they are used for. It compares reverse proxy caches with standard and transparent proxy caches, explaining the different functionality each provides. The paper illustrates how the reverse proxy actually caches the content and delivers it to the client. It also describes how to configure Squid as a reverse proxy cache.
