摘要： A solution for network packet latency measurement includes, at a network device having a memory, storing a first time value indicating when an ingress port of the network device received a packet. The solution also includes storing a second time value indicating when an egress port of the network device received the packet for transmission towards another network device. The solution also includes storing a difference between the first time value and the second time value.

摘要： A network architecture provides Ethernet services over a Fibre Channel (FC) storage area network infrastructure. The fabric provides transparent bridging services to Ethernet end stations connected at the edge of the FC fabric via multi-protocol switches that support Ethernet over Fibre Channel (EoFC) technology. An Ethernet frame is received from a first Ethernet edge network by an ingress Ethernet port of a first virtual bridge and is encapsulated in a FC frame shell to form an EoFC frame. The EoFC frame is then transmitted out an egress FC port of the first virtual bridge and routed through the FC fabric using an FC routing protocol. When the encapsulated frame reaches an ingress FC port of a second virtual bridge, the EoFC frame is de-encapsulated to yield the original Ethernet frame, which is transmitted out an egress Ethernet port of the second virtual bridge into a second Ethernet edge network.
摘要翻译：网络架构通过光纤通道（FC）存储区域网络基础架构提供以太网服务。该架构通过支持以太网光纤通道（EoFC）技术的多协议交换机为连接在FC结构边缘的以太网端站提供透明桥接服务。通过第一虚拟桥的入口以太网端口从第一以太网边缘网络接收以太网帧，并且封装在FC帧外壳中以形成EoFC帧。然后，EoFC帧被发送出第一个虚拟网桥的出口FC端口，并使用FC路由协议通过FC结构路由。当封装帧到达第二个虚拟网桥的入口FC端口时，EoFC帧被解封装，以产生原始以太网帧，该帧从第二个虚拟桥的出口以太网端口发送到第二个以太网边缘网络。

摘要： A switch creates and dynamically updates a latency map of a network to adjust routing of flows. Further, the network is monitored to detect latency issues and trigger a dynamic adjustment of routing based on the latency map. In this manner, a flow can be routed along a route (i.e., a faster route) that provides less latency than other available routes. The latency map can be generated based on latency probe packets that are issued from and returned to the source switch. By evaluating many such latent probe packets that have traveled along many available routes (e.g., corresponding to various ports of the switch), the switch or associated administrative logic can dynamically adjust the latency map to updated latency information of available routes. Therefore, responsive to a trigger, the source switch can dynamically adjust the routing of a flow based on latency issues discerned from the network.

摘要： Systems and techniques for processing and forwarding packets are described. Some embodiments provide a system (e.g., a switch) which determines an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and forward the packet based on the internal virtual network identifier and/or internal policy identifier. In some embodiments, the system encapsulates the packet in a TRILL (Transparent Interconnection of Lots of Links) packet by adding a TRILL header to the packet. In some embodiments, the scope of an internal virtual network identifier and/or an internal policy identifier may not extend beyond a switch or a module within a switch.
