cFosSpeed 4.21 Build 1403 cFosSpeed is a Traffic Shaping driver for DSL modems and routers. ===========================================What is NEW cFosSpeed 4.21 Build 1402/1403===========================================-Added a switch to log all TCP connections with their adresses, ports,statistics, etc. to a disk file. This may be good if you want to seewhat happened, when you didn\'t watch the status window. The data of thesessions is not saved, only statistics.-To activate set \"spd gset log_sessions 1\". Add a \"-save\" if you want tokeep it activated after a restart. The disk file is calledsession_log.txt; you can set it max size with gset variablemax_session_log_size, default is 1mb.-Added spd command \"tcb\" to show interactively some of the info that iswritten to session_log.txt.cFosSpeed is a network driver, which attaches itself to existing Internet connections. It then optimizes data transfer by means of Traffic Shaping.Traffic Shaping is a method for optimizing the Internet traffic. It allows maximum speed while ensuring minimal Ping.You can use cFosSpeed with a router and/or a DSL-modem or cable-modem. You can also use cFosSpeed with other types of Internet access, ie. whenever youalready have an existing Internet connection.cFosSpeed supports a wide variety of connections, like DSL, cable, ISDN, UMTS, etc.cFosSpeed has two goals: 1. Keep network delays (ping times) small, in order to make Internet applications as responsive as possible. 2. Improve data throughput by avoiding network congestions.You can use cFosSpeed with an Internet connection you use exclusively or which you share with several PCs. cFosSpeed features list***********************-Connections:: * Broadband: Cabel and DSL * Narrow band: Modem and ISDN * Mobile (UMTS, HSDPA, GSM, GPRS, HSCSD) * Media: o DSL, PPPoE o DSL, PPPoA (VCmux and LLC) o DSL, PPTP o VDSL o Cable o ISDN o IP over AAL o RFC1483/2684 bridged-Routing: * Router and dial-up connections * LAN and WLAN * Router and Bridge-Mode * VPN * Multiple connections simultaneously * Adjustable routes * Several IP adresses per adapter-Traffic Shaping: * Multi-User version * TX and RX-Shaping * L7 Protocol Analysis * Prioritization of Programs * RTP/VoIP Detection * 5 priority queues * Individual rules with filter language-Options: * Low-Latency Mode * Auto-MTU optimization-Extras: * Time and volumen budgets * Usage Graph * Overview of connections * Skin-Windows * Firewall * Data and packet logging * 32-Bit and 64-Bit version * 12+ languages Traffic Shaping for Filesharing (P2P)Traffic Shaping technology does keep ping times low and transfer rates consistently high at the same time. Filesharing (P2P) benefits from Traffic Shaping in two ways: 1. Traffic Shaping allows simultaneous upload(s) and download(s) at full speed. With no Traffic Shaping, upload(s) and download(s) choke each other to a crawl. 2. Filesharing uses up a lot of bandwidth and may interfere with other applications running on the same connection by increasing request-response times dramatically. As a result, just a simple click on a Web site may take several seconds to be processed while data are being transferred at the same time. -The priority scheme integrated in cFos and cFosSpeed (re)organizes data packets in a manner that ensures maximum download rates for filesharing programs. In addition, cFos and cFosSpeed prioritize filesharing data transfer down. Now, this should not be taken to mean such traffic is artificially slowed or even altogether stalled. What it does mean, however, is that such data will be briefly delayed when more important data is being transmitted. Only this priority scheme makes it possible to have filesharing programs run at maximum transfer rates while still using the same connection for other applicationsat the same time.-For instance, if you have a filesharing program running in the background when surfing the Net, there will only be a brief, minimal slowdown in P2P trafficwhile a new page is being loaded. Likewise, when sending out longer e-mails, P2P upload rates may briefly drop somewhat while the mail is being transmitted.Once the mail is sent, all uploads will continue at full speed again. The only alternatives would be to postpone transmission of the mail \"forever\" or artificially limit transfer bandwidth for filesharing somehow. But this would also mean a loss of bandwidth even when no other application is using the same connection. In short, cFos and cFosSpeed let you use the full bandwidth for P2P networks.Prioritization:-Quite a few users have one PC set aside specifically for filesharing and route P2P traffic (e.g., via Internet Connection Sharing) through a main computerdirectly hooked up to the Internet. In this case, the Layer-7 Protocol Detection integrated in cFos and cFosSpeed permits priroritization of the mostimportant P2P networks like BitTorrent, eDonkey 2000 (eMule, etc.), Kazaa, Gnutella(2), Kademlia, and Direct Connect.Prioritizing Programs:-cFos and cFosSpeed also permit prioritizing programs by their name. Many of the most important programs have already been included in our program setting list. This way of prioritizing is especially useful when the Layer-7 detection cannot recognize and assign data properly (as would, for instance, be the case with encrypted P2P traffic).Optimizing Connection Settings:-You can specify exactly what transfer medium you use under Connection Settings. Default is \"Adaptive.\" But if you were for instance using a DSL connection, you should select the appropriate DSL standard or protocol as your medium.
