摘要： Apparatus, methods, and other embodiments associated with providing service insertion architecture (SIA) differentiated services in a virtual private network (VPN) environment are described. Embodiments may provision an authentication, authorization, and accounting (AAA) server with user-to-SIA service-context mapping information. With the AAA server provisioned, embodiments may acquire, in an IPSec VPN hub, during IPSec tunnel user authentication, from the AAA server, the user-to-SIA service-context mapping information. With the mapping information available, embodiments may dynamically map an SIA service to an IPSec VPN tunnel user based on the service information acquired from the Service Broker or Pseudo-Service Broker. The dynamic mapping facilitates providing differentiated services in the SIA by facilitating forwarding an IPSec packet received on the IPSec VPN tunnel from the user to a service node associated with the SIA service based, at least in part, on the IPSec SADB entry modified using the service information.

摘要： Systems, methods, and other embodiments associated with interworking a VPN and an SIA are described. One example apparatus includes a mapping data store to store a mapping between two logical groups of network devices having separate forwarding planes that are at least partially incompatible. The apparatus includes an instantiation logic to establish the mapping based on unique identifiers associated with the logical groups. The apparatus also includes an encoding logic to implicitly encode information to identify the first logical group in a packet received from the first logical group, provided to the second logical group, and then provided back to the first logical group. The implicitly encoded information is configured to be used without modification by the forwarding plane associated with the second logical group and is configured to facilitate a member of the second logical group resolving the mapping.

摘要： A multi-layer network element for forwarding received packets from an input port to one or more output ports with quality of service. When output queues exceed or meet a threshold value below the queue's capacity packets are ramdomly discarded. When the queue becomes full, the network element determines which flow caused the queue to overflow. The priority of that flow is lowered. In a multicast packet, the packet may have different priorities at each output port. Scheduling of multiple output queues at each output port uses a weight round robin approach that allocates a weight portion of packets to transmit at each time interval. A packet is not interrupted during its transmission, even if the weight portion is met during a packet's transmission. The excess number of bytes transmited as a result of not interrupting the packet are accounted for in the next round.

摘要： In an example embodiment, packets for a selected flow are replicated and sent over one or more diverse paths, such as a primary path and at least one secondary path, to a destination switching device. At the destination switching device, one copy of the replicated packets is selected for delivery to the destination, and the remaining copies are discarded. In the event that packets are not received at the destination switching device due to loss of connection on the primary path or packets are not timely delivered due to congestion on the primary path, a different path may be selected as the primary path.

摘要： The invention generally provides for a network element and methods in the network element for allowing a matching entry in a forwarding memory to be found in a single search of the memory, for determining when an entry should be placed in the memory, and for determining when an entry should be removed from the memory, in order to make more efficient use of the fixed space available in the memory. The invention is particularly useful in making more efficient use of a Content Addressable Memory (CAM) for storing flow entries, and configuring the CAM to index an associated memory that stores forwarding and quality of service information for each CAM entry.

摘要： A multi-layer network element for forwarding received packets from an input port to one or more output ports. The packet is examined to look for different types of forwarding information. An associative memory is searched once for each type of information. The results from the two searches are combined to forward the packet to the appropriate one or more output ports. The packet may be examined for other information as well to make the forwarding decisions. In one embodiment, the invention examines the packet for layer 2 information as the first type and layer 3, and perhaps some layer 4, information as the second type. The results are merged to determine the most appropriate combination of layer 2 or layer 3 forwarding decisions for the packet.
