摘要： A compensator for optical transmission systems exploits gain tilt inherent in optical amplifiers. The amount of SRS induced spectral power gradient is determined, and the amplifier gain is changed to cause a compensating gain gradient in the optical amplifier to compensate for the SRS induced spectral power gradient. Fewer components are needed, and so it can be less expensive. It can be implemented as a simple software upgrade to existing systems. Many such compensators can be distributed through the system, without requiring a large inventory of individually specified filters. More accurate compensation can be achieved by making it dependent on the distribution of wavelengths within a band.

摘要： The invention provides a method of balancing the power level of an optical signal within an aggregate of optical signals in an amplified dense wavelength division multiplexing DWDM optical network, as well as power balancing apparatus therefor. The method involves measuring the power level of the optical signal received at an optical receiver through the optical link and referencing said measured receive power level to a nominal power level in the multiplex immediately preceding the receiver; measuring the power level of the optical signal at an optical transmitter and referencing said measured transmit power level to a nominal power level in the multiplex immediately following the transmitter; calculating a mean power level of the optical signal from said optical measurements, the mean power level of the optical signal being the mean of the power levels of the optical signal at the transmitter and at the receiver referenced to the nominal power levels in the associated multiplexes; and adjusting the mean power level of the optical signal independently of the power levels of other optical signals carried on the same optical link to the receiver so that a desired OSNR at the receiver is achievable.

摘要： Previous systems and methods for personalizing web content presented to a user has been achieved in a decentralized manner by storing personal data relating to the user repeatedly by different content providing servers. Consequently, the consistency of the data stored can be inconsistent and, in some cases, incomplete. Additionally, the user does not have any control over the dissemination of the content. The present invention provides a system, apparatus and method whereby web related data is modified in communications between user equipment units and content providing servers. The modification to the web related data is carried out by a proxy server (20) having access to centrally stored personal data in a data store (22). Consequently, data provided to content providing servers is consistent, complete and the information provided by the content providing servers to the user has a higher degree of relevance to the user.
摘要翻译：用于个性化呈现给用户的web内容的以前的系统和方法已经以分散的方式通过不同内容提供服务器反复存储与用户有关的个人数据来实现。因此，存储的数据的一致性可能不一致，在某些情况下也是不完整的。此外，用户无法控制内容的传播。本发明提供了一种在用户设备单元和内容提供服务器之间的通信中修改Web相关数据的系统，装置和方法。对web相关数据的修改由可访问数据存储器（22）中的集中存储的个人数据的代理服务器（20）执行。因此，提供给内容提供服务器的数据是一致的，完整的，并且由内容提供服务器向用户提供的信息对用户具有更高程度的相关性。

摘要： In IPv6, a multi-homed domain comprises more than one connection to domains disposed hierarchically above the multi-homed domain. Consequently, more than one set of IP addresses exists corresponding to the more than one connection between the multi-homed domain and the hierarchically higher domains, respectively. At present, a first host associated with the multi-homed domain must choose between one of the more than one set of IP addresses in ignorance of the existence of a fault condition arising in connection with one of the sets of IP addresses, resulting in the first host becoming unreachable by a second host located elsewhere in the Internet. The present invention therefore provides a system, method and apparatus whereby a given domain transmits an address prefix to domains disposed hierarchically below the given domain and forward address prefixes received from domains disposed hierarchically above the given domain to domains disposed hierarchically below the given domain.
摘要翻译：在IPv6中，多归属域包含多个连接到多归属域上分层上放置的域的连接。因此，分别存在多个IP地址集合，其对应于多归属域和分级较高域之间的多于一个的连接。目前，与多归属域相关联的第一主机必须在多于一组的IP地址中的一个之间选择，因为它与IP地址中的一组相关联的故障状况的存在无知，导致第一个主机由位于互联网其他地方的第二个主机变得无法访问。因此，本发明提供了一种系统，方法和装置，其中给定域将地址前缀发送到分级地放置在给定域之下的域，以及从分级地放置在给定域上方的域接收的转发地址前缀到分级地放置在给定域下面的域。
