    Abstract: A method and system for best effort propagation of security group information is disclosed. The method includes determining if a reserved group identifier is associated with a destination and, if the reserved group identifier is associated with the destination, indicating that a packet received at a network node can be sent to another network node. The packet includes destination information that identifies the destination as a destination of the packet.

    Abstract: A method and apparatus for providing network security using role-based access control is disclosed. A network device implementing such a method can include, for example, an access control list. Such an access control list includes an access control list entry, which, in turn, includes a user group field. Alternatively, a network device implementing such a method can include, for example, a forwarding table that includes a plurality of forwarding table entries. In such a case, at least one of the forwarding table entries includes a user group field.

    Abstract: Presented herein are techniques useful in a network comprising a plurality of network nodes each configured to apply one or more service functions to traffic that passes through the respective network nodes. A network node receives packets encapsulated in a service header that includes information defining a variable set of context headers stacked into an association of metadata that is relevant to one or more service functions within a service path comprised of one or more network nodes. The network node interprets a forwarding state and a next-hop network node for the service path from the service header, and determines a service action or associated metadata from the set of context headers.

    Abstract translation: 这里呈现的是在网络中有用的技术，其包括多个网络节点，每个网络节点被配置为将一个或多个服务功能应用于通过各个网络节点的业务。 网络节点接收封装在服务头部中的分组，该分组包括定义一组上下文标题的信息，这些信息堆叠成与由一个或多个网络节点组成的服务路径内的一个或多个服务功能相关的元数据关联。 网络节点从服务头解释用于服务路径的转发状态和下一跳网络节点，并且从上下文头集合中确定服务动作或相关联的元数据。
