摘要： Techniques for transmitting a packet from a source switch module to a destination switch module. Embodiments retrieve path information specifying a route to the destination switch module. A packet is created that includes (i) at least a portion of the path information and (ii) a set of load/store operations to be executed by the destination switch module. Embodiments then transmit the packet to a first switch module using a first port, the first port specified in the retrieved path information. The first switch module is configured to transmit the packet based on the at least a portion of the path information in the packet, and the destination switch module is configured, upon receiving the packet, to copy the set of load/store operations into an execution buffer to be automatically executed.

摘要： Techniques are provided for multicast miss notification for a distributed network switch. In one embodiment, a bridge element in the distributed network switch receives a frame destined for a multicast group on a network. If a local multicast forwarding table of the bridge element does not include any forwarding entry for the multicast group, a forwarding entry is selected from the local multicast forwarding table as a candidate for being replaced. An indication of the candidate is sent to a management controller in the distributed network switch.

摘要： Techniques are provided for cached routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry, based on a set of hash functions. Upon accessing the generated routing entry in the modified routing table responsive to a subsequent lookup request for the source address, the set of caches is modified to include the generated routing entry.

摘要： Techniques for transmitting a packet from a source switch module to a destination switch module. Embodiments receive, at a first port of a first switch module, a packet that includes (i) path information specifying a route to the destination switch module and (ii) a set of load/store operations to be executed by the destination switch module. An indication of the first port is inserted into a return path information portion of the received packet. Upon determining that the first switch module is not the destination switch module, embodiments transmit the packet to a second switch module using a second port, the second port specified in the path information of the received packet, wherein the destination switch module is configured, upon receiving the packet, to copy the set of load/store operations into an execution buffer to be automatically executed.

摘要： A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. Moreover, each surrogate may optimize the hierarchy according to one or more optimization criteria. For example, each surrogate in the hierarchy may have the necessary information to ensure that if the next surrogate in the hierarchy is unavailable, the data may be routed to a backup surrogate. The selected hierarchy may be further optimized by skipping surrogates (or a surrogate level) such that the data intended for a skipped surrogate is sent to a surrogate in a lower-level of the hierarchy. This may better utilize the connection interfaces in the transmitting sub-switches and eliminate any unnecessary surrogate-to-surrogate transfers.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions and properties of the slices.

摘要： A distributed switch may include a plurality of sub-switches. These sub-switches may be arranged in a hierarchy that increases the available bandwidth for transmitting multicast data frames across the switch fabric. Moreover, the distributed switch may be compatible with link aggregation where multiple physical connections are grouped together to create an aggregated (logical) link. Link aggregation requires similar data frames to use the same data path when traversing the distributed switch. With a unicast data frame, the sub-switch in the distributed switch that receives the data frame typically identifies the destination port (during a process called link selection) and forwards the data frame to the sub-switch containing that port. However, with multicast data frames, instead of the receiving sub-switch performing link selection to determine the destination port, link selection may be done by a different sub-switch or not done at all.
摘要翻译：分布式交换机可以包括多个子交换机。这些子交换机可以以层次结构来布置，从而增加跨越交换结构传输多播数据帧的可用带宽。此外，分布式交换机可以与链路聚合兼容，其中多个物理连接被分组在一起以创建聚合（逻辑）链路。链路聚合需要相似的数据帧才能在穿过分布式交换机时使用相同的数据路径。通过单播数据帧，接收数据帧的分布式交换机中的子交换机通常识别目的端口（在称为链路选择的过程中），并将数据帧转发到包含该端口的子交换机。然而，使用组播数据帧，代替执行链路选择的接收子交换机来确定目的地端口，链路选择可以由不同的子交换机完成，或者根本不完成。

摘要： Link aggregation is a practice that uses multiple Ethernet links between two end points in order to obtain higher bandwidth and resiliency than possible with a single link. A flow distribution technique is provided to distribute traffic between the two end points equally across all links in the group and achieve greater efficiency. The flow distribution technique generates and sub-divides a hash value based on received packet flow. The divided portions of the hash value are used in a hierarchical fashion to select a link to use for this packet.
