Abstract: A monitoring session associated with a virtual nickname may be established in a TRILL network. A monitoring station may be connected to an edge switch of the TRILL network specifying the virtual nickname for the monitoring session. The monitoring station is set as a destination for the monitoring session and the virtual nickname is flooded throughout the TRILL network. A source may then be configured to the monitoring session by specifying the virtual nickname of the monitoring session without knowing the destination tied to the monitoring session. Network traffic through the source may then be forwarded to the destination tied to the monitoring session.

Abstract: The methods and devices discussed herein provide service clustering within a TRILL network without relying on an additional service insertion framework. A TRILL network can include one or more flow distribution RBridges for distributing flows to service nodes. Each flow distribution RBridge can have a virtual base identifier and one or more virtual cluster identifiers. An example method can include maintaining service cluster load balancing structures and receiving a packet that is encapsulated with an inner header and an outer header. The method can include determining whether the egress RBridge identifier is a virtual cluster identifier, and if so, selecting a service node from one of the service cluster load balancing structures. The method can include forwarding the packet to the selected service node.

Abstract: The methods and devices discussed herein provide service clustering within a TRILL network without relying on an additional service insertion framework. A TRILL network can include one or more flow distribution RBridges for distributing flows to service nodes. Each flow distribution RBridge can have a virtual base identifier and one or more virtual cluster identifiers. An example method can include maintaining N service cluster load balancing structures and receiving a packet that is encapsulated with an inner header (source/destination addresses) and an outer header (ingress/egress RBridge identifiers). The method can include determining whether the egress RBridge identifier is a virtual cluster identifier, and if so, applying a hash function to a predetermined flow tuple and selecting a service node associated with the hash value from one of the N service cluster load balancing structures. The method can include forwarding the packet to the selected service node.

Abstract: In one embodiment, a copy of an original packet of a traffic flow is created at an ingress leaf node of a cloud switch. The ingress leaf node forwards the original packet along a less-specific path through the cloud switch, the less-specific path based on a domain index of an egress domain for the original packet. The copy of the original packet is modified to create a more specific path learn request packet. The ingress leaf node forwards the more specific path learn request packet along the less-specific path through the cloud switch. The ingress leaf node received back a more specific path learn request reply packet that includes an indication of a fabric system port. The ingress leaf node then programs a forwarding table based on the indication of the fabric system port, to have subsequent packets of the traffic flow forwarded along a more-specific path.

Abstract: Accelerating network convergence may be provided. Consistent with embodiments of the disclosure, a mapping server may be configured to map an interconnection of various network elements comprising at least the following: a wireless host, at least two access switches, a plurality of distribution switches, a core switch, a mobility controller, and a mapping database. The mapping server may then receive an indication from the mobility controller that the wireless host has roamed from a first access switch to a second access switch. In response to the indication, the mapping server may remap the interconnection of network elements in the mapping database to update network routing information associated with the wireless host.
Abstract translation: 可以提供加速的网络融合。 与本公开的实施例一致，映射服务器可以被配置为映射至少包括以下的各种网络元件的互连：无线主机，至少两个接入交换机，多个分布交换机，核心交换机，移动性控制器 ，以及映射数据库。 然后，映射服务器可以从移动性控制器接收到无线主机已经从第一接入交换机漫游到第二接入交换机的指示。 响应于该指示，映射服务器可以重新映射映射数据库中的网络元件的互连，以更新与无线主机相关联的网络路由信息。

Abstract translation: 在一个实施例中，在云交换机的入口叶节点处创建业务流的原始分组的副本。 入口叶节点通过云交换机沿较不具体的路径转发原始数据包，该原始数据包是基于原始数据包的出口域的域索引的较不具体的路径。 修改原始数据包的副本以创建更具体的路径学习请求数据包。 入口叶节点通过云交换机沿较不具体的路径转发更具体的路径学习请求分组。 入口叶节点接收到更特定的路径学习请求应答分组，其包括结构系统端口的指示。 因此，入口叶节点基于结构系统端口的指示对转发表进行编程，以使业务流的后续分组沿着更具体的路径转发。
