摘要： A Virtual Communication Environment to support virtual switching engines for layer 2 switches is described. The virtual layer 2 switching engines allow many virtual switches to be created in a CPU or across multiple CPUs in switching hardware. The virtual switch engines reduce the inter-communication costs in memory, CPU, inter-process bandwidth, and fabric bandwidth. This reduction in the cost per Virtual Switch device allows either more virtual switches to be contained within a control plane or more applications per switch control plane.

摘要： This invention has two mechanisms: Dynamic AS switching for AS confederations and Dynamic AS switching. The Dynamic AS switching for AS confederation mechanism provides a mechanism for an Autonomous System within an AS confederation to survive disconnection from the rest of the Autonomous Systems within the AS Confederation. This invention provides a mechanism for the AS within the AS confederation to use a pre-agreed upon fail-over to the internal AS, so its eBGP connections will not be reset. The Dynamic AS switching mechanisms allows to peers to re-negotiate AS number changes in any Autonomous Systems the peer represent without dropping the BGP peering session.
摘要翻译：本发明有两种机制：AS协议的动态AS切换和动态AS切换。用于AS联盟机制的动态AS切换为AS联盟内的自治系统提供了一种机制，可以与AS联盟内的其他自治系统断开连接。本发明提供了一种用于AS联盟内的AS使用对内部AS进行预先同意故障切换的机制，因此其eBGP连接将不会被重置。动态AS交换机制允许对等体在对等体代表的任何自治系统中重新协商AS号码变化，而不会丢弃BGP对等体会话。

摘要： Extensions to the ES-IS protocol are described which include virtual nodes and virtual sub-network identifiers. Techniques for selecting a physical IS forwarder amongst multiple candidates in a virtual node may include tie-breaking mechanisms based on pre-emption values supported by the ES-IS extensions Embodiments allow integration between ES-IS based broadcast networks supporting the Internet Protocol (IP) and the Virtual Router Redundancy Protocol (VRRP). In some embodiments, this integration is accomplished in part by translating packet data units between ES-IS and versions of VRRP. In some such embodiments, nodes on an internetwork maintain concurrent state tables for ES-IS and VRRP.
摘要翻译：描述了包括虚拟节点和虚拟子网络标识符的ES-IS协议的扩展。用于在虚拟节点中的多个候选者之中选择物理IS转发器的技术可以包括基于由ES-IS扩展所支持的优先级值的断开机制。实施例允许基于支持因特网协议（IP）的基于ES-IS的广播网络之间的集成，和虚拟路由器冗余协议（VRRP）。在一些实施例中，该集成部分地通过在ES-IS和版本的VRRP之间转换分组数据单元来实现。在一些这样的实施例中，互联网络上的节点保持用于ES-IS和VRRP的并发状态表。

摘要： Policy domains are introduced, which include methods and algorithms for ensuring policy consistency within defined regions of one or more communications networks. Examples of such policies include network functions such as routing, filtering, security, authentication, information summarization and expansion. These policies may be organized into hierarchies of policy categories. The policy domains include mechanisms for adding and deleting policies while preserving consistency, as well as mechanisms for allowing fast synchronization and convergence of policies between local databases resident different nodes/peers in the networks. Policy domains may delineated by pre-existing logical topologies, such as autonomous systems, or may have evolving boundaries.
摘要翻译：引入了策略域，其中包括确保一个或多个通信网络的定义区域内的策略一致性的方法和算法。这种策略的示例包括网络功能，如路由，过滤，安全性，认证，信息汇总和扩展。这些政策可能被组织成政策类别的层次结构。策略域包括添加和删除策略同时保持一致性的机制，以及允许本地数据库驻留在网络中的不同节点/对等体之间的策略的快速同步和收敛的机制。策略域可以通过预先存在的逻辑拓扑（例如自治系统）来描绘，或者可能具有不断变化的边界。

摘要： Packet formats for routing protocols which combine link state and path vector routing techniques are described. Such protocols are referred to as Link State Path Vector (LSPV) protocols. Embodiments of the invention include extensions to protocols such as the Border Gateway Protocol (BGP) and Intermediate Standard to Intermediate Standard (IS-IS). Embodiments also include packet formats for LSPV protocols which align the bytes of the one or more LSPV protocols with bytes in formats for protocols in the prior art.
