摘要： The embodiments of the present invention relate to a method in a transmitting node; a method in a receiving node; a transmitting node and a receiving node in an IP network employing Internet security. The receiving node comprises a Receiving Unit, a Processing Unit and a Transmitting Unit. When an IP packet is received, the Processing Unit is adapted to derive a Security Association and a Traffic Class associated with the IP packet. The Processing unit is also adapted to maintain one anti-replay window for each Traffic Class within the Security Association and to determine if a sequence number of the IP packet is within the anti-replay window of the Traffic Class and is not a duplicate of an earlier received packet. If said sequence number is not within the anti-replay window or is a duplicate of an earlier received packet, the packet is dropped.

摘要： An AAL2 path group (60) comprises plural AAL2 paths (35). Bandwidth of an individual AAL2 path comprising the AAL2 path group is contributed to a total bandwidth of the AAL2 path group rather than to the individual AAL2 path exclusively. An admission decision regarding a connection seeking to use an AAL2 path belonging to the AAL2 path group is based on available bandwidth of the AAL2 path group rather than available bandwidth of an individual AAL2 path. ATM VCCs which comprise the AAL2 path group are transported on a virtual path (VP) together with ATM VCCs of a different type (e.g., a second type which differs from a first type of ATM VCC which comprise the AAL2 path group). The AAL2 path group also features quality of service (QoS) separation, e.g., differing treatment for differing AAL2 connections within the AAL2 path group based on the QoS requirements for the differing AAL2 connections.
摘要翻译： AAL2路径组（60）包括多个AAL2路径（35）。包含AAL2路径组的单个AAL2路径的带宽对AAL2路径组的总带宽而不是专用于单独的AAL2路径贡献。关于寻求使用属于AAL2路径组的AAL2路径的连接的接纳决定基于AAL2路径组的可用带宽而不是单个AAL2路径的可用带宽。构成AAL2路径组的ATM VCC与与不同类型的ATM VCC（例如，与构成AAL2路径组的第一类型的ATM VCC不同的第二类型）一起在虚拟路径（VP）上传送。 AAL2路径组还具有服务质量（QoS）分离，例如，基于不同AAL2连接的QoS要求，对AAL2路径组内的不同AAL2连接进行不同的处理。
