摘要： A method, apparatus and computer program product for providing mulitcast failover and recovery which minimizes lost packets is presented. A first network device returns to a fully active state and starts a multicast hold-down timer. A first message is sent to a second network device, the message indicating at least one Split Multi Link Trunk (SMLT) Virtual Local Area Network (VLAN) Identifier (ID) correlating to the multicast hold-down timer. The first network device receives an acknowledgment of said first message and Layer 2 forwards multicast data traffic to said second network device until the timer expires, whereupon the first device is capable of handling its own multicast data traffic, and then has Layer 2 bridging turned off and enables IP multicast routing. During the period of multicast hold-down timer, the second device will perform IP multicast forwarding on behalf of the first device.

摘要： Multiple non-conflicting actions associated with filter rules may be located and applied to a packet using a single ACL lookup by causing action records to be created from ACEs in the ACL, and then causing the ACL lookup to return the action record rather than any one particular ACE. Radix tables may be created to enable a search engine to quickly locate the appropriate action record based on a particular set of attributes associated with the incoming packet. The action record can contain multiple actions taken from multiple ACEs that apply to the particular packet. By grouping all the actions into an action record, and then searching for an action record that applies to the packet, it is possible to apply all non-conflicting actions to the packet regardless of the number of ACEs that are used to specify those actions. Since all the actions are located together, the actions of all ACEs may be applied to a packet using a single ACL lookup.

摘要翻译： 可以使用单个ACL查找来定位与过滤器规则相关联的多个非冲突操作，并通过使ACL中的ACE创建操作记录，然后使ACL查找返回操作记录而不是任何一个 特别的ACE。 可以创建基表，以使搜索引擎能够基于与输入分组相关联的一组特定属性快速定位适当的动作记录。 动作记录可以包含从适用于特定数据包的多个ACE采取的多个操作。 通过将所有操作分组到操作记录中，然后搜索适用于数据包的操作记录，可以将所有非冲突操作应用于数据包，而不管用于指定这些操作的ACE数量如何。 由于所有操作都位于一起，因此可以使用单个ACL查找将所有ACE的操作应用于数据包。

摘要： IP Multinetting on a local area network is simulated by performing VLAN translation at a port connecting to the local area network. This allows IP addresses from multiple subnets to be associated with a single VLAN on the Local Area Network (LAN), while allowing the core switch to process the packets with a one-to-one correspondence between IP Subnet and VLAN. When a packet is received from the local area network at an IP multinetting port, the VLAN ID will be read to determine if the packet contains the IP Multinetting VLAN ID. The IP Subnet address will also be checked to see if the packet is associated with an IP Subnet that is part of the Multinetting. If so, the multinetting VLAN ID will be changed to an IP Subnet specific VLAN ID before the packet is processed by the core switch.

摘要翻译： 通过在连接局域网的端口上进行VLAN转换来模拟局域网上的IP Multinetting。 这允许来自多个子网的IP地址与局域网（LAN）上的单个VLAN相关联，同时允许核心交换机以IP子网和VLAN之间一一对应的方式处理数据包。 当在IP多端口从局域网接收到数据包时，将读取VLAN ID，以确定该数据包是否包含IP Multinetting VLAN ID。 还将检查IP子网地址，以查看该数据包是否与作为Multinetting一部分的IP子网相关联。 如果是这样，在核心交换机处理数据包之前，多VLAN VLAN将被更改为IP子网特定的VLAN ID。

摘要： Systems and methods are disclosed of routing traffic in a network that include classifying incoming data packets using the content of the incoming data packets that remains relatively consistent during a network session. These systems and methods also include ordering the incoming traffic according to at least one internet protocol address comprised within the incoming traffic, hashing the at least one internet protocol address and the destination port within the incoming traffic, and determining a destination service module for the incoming traffic. Through these systems and methods, data can be routed without the need for complete flow tables.
