''Hart v. Comcast'' was a suit filed by Jon Hart, a citizen of California against Comcast in Alameda County. Comcast is a provider of internet access and services. The suit alleged that Comcast was illegally interfering with certain types of internet traffic, such as BitTorrent. The suit alleged that Comcast is guilty of false advertising for advertising high speed service yet deliberately using technology to interfere with access speeds. The suit also claimed Comcast's actions violated established Federal Communications Commission policies on Net Neutrality. The case has since been settled out of court.〔(【引用サイトリンク】 accessdate = 2011-09-15 )〕 The suit states: Hart has requested that the suit be declared a class action suit so that all Comcast customers in California can receive damages under the suit. == Comcast High-speed internet service == Comcast, the largest cable provider in the United States, offers downstream speeds of up to 4, 6, 8, or 17.6 Mbit/s and upstream speeds of 384 kbit/s (48 kB/s), or 768 kbit/s (96 kB/s) for the 8 Mbit/s downstream package, for standard home connections. According to the Comcast High Speed Internet terms of service, customers are provided with dynamic IP addresses.〔(Comcast, ''Comcast High-Speed Internet Acceptable Use Policy'' )〕 Despite the general expectation that Comcast's service is unlimited, Comcast has a policy of terminating broadband customers who allegedly use excessive bandwidth. Comcast has declined to disclose a numerical bandwidth limit, arguing that the limit is variable on a monthly basis and dependent on the capacity of specific cable nodes. Comcast claims this policy only affects users whose bandwidth consumption is among the top one percent of high-speed internet customers. Statements issued by Comcast in response to press inquiries suggest that excessive usage is generally defined as several hundred gigabytes per month.〔(The Boston Globe, ''Not so fast, broadband providers tell big users'' )〕〔(The New York Times, ''Say Good Night, Bandwidth Hog'' )〕 However, their terms of service state that a customer's use should not "represent (in the sole judgment of Comcast) an overly large burden on the network."〔 Comcast has implemented traffic shaping measures using Sandvine hardware which sends forged RST packets, disrupting the BitTorrent protocol. This has prevented some Comcast users from uploading, or "seeding" files they have downloaded via BitTorrent. Some Comcast users also may experience packet loss and latency, resulting in lag. This effect is most often noticed when dealing with time critical traffic in online gaming, and especially pronounced when such users host online games on ad-hoc networks (such as in Halo 3). This practice is becoming an increasingly common trend. The effects of packet loss and latency vary greatly depending on locale and the conditions of the local plant. Some Comcast customers may experience severe packet loss, while others may see no packet loss. The issues resulting from local variables affect all Internet Service Providers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hart v. Comcast Corp.」の詳細全文を読む スポンサード リンク
