20120020205 | PROTECTING CONNECTION TRAFFIC USING FILTERS - A connection between network nodes in a communication network is backed up. A failover switched path such as a label-switched path (LSP) is created starting at a first network node of a connection and ending at the second node of the connection, while bypassing the protected connection. In the event of connection failure, data is transmitted through the failover switched path (e.g., LSP). A network operator can selectively protect different types of data by using filters that bind one or more types of traffic received over one or more interfaces to different failover switched paths (LSPs). | 01-26-2012 |

20150124652 | WEIGHTED EQUAL COST MULTIPATH ROUTING - In some implementations, network traffic can be routed along equal cost paths based on weights assigned to each path. For example, weighted equal cost multipath routing can be implemented by assigning weights to each equal cost path (e.g., uplink, next hop node) to a destination device. When the network device receives a packet, the network device can generate a key (e.g., a random value, a hash value based on packet data, a value between 0 and n, etc.). The key can be used to select an uplink or path upon which to forward the packet. A key can be generated for a packet flow or flowlet. Each flow can be associated with the same key so that each packet in a flow will be forwarded along the same path. Each flowlet can be forwarded along a different uplink. | 05-07-2015 |
