Methods are provided for communicating between devices in a network and remote servers, which may be located behind intermediate devices such as load balancers, by encapsulating messages sent by those devices and, in one implementation, to a load balancer in a transport header that may be understood by that load balancer; decapsulating the message from the transport header; re-encapuslating the message in a GRE tunnel and passing the message to a server, where the GRE tunnel is removed. Methods are also provided for communicating between devices in a network and local gateways by encapsulating messages sent by those devices and, in one implementation, to a load balancer in a transport header that may be understood by that gateway, and decapsulating the message from the transport header at the gateway.

An example network device includes a network interface and a control unit that receives a packet having header information. The control unit includes a forwarding structure having a plurality of entries that each refers to one of a plurality of logical interfaces, a forwarding engine configured to access the forwarding structure to select a first logical interface to which to forward the packet based on the header information, wherein the first logical interface comprises a pseudo-device interface (PDI). The control unit also includes a PDI module that tunnels the packet to an external service complex (ESC) by at least applying a set of metadata to the packet, encapsulating the packet with a header, and forwarding the packet to the ESC via the network interface, and wherein the metadata allows the ESC to determine a set of services to be applied to the packet based on the metadata.

Interface for extending service capabilities of a network device

Resource utilization required for processing packets associated with multilink bundles of a router are tracked. Corrective actions can be taken to provide fair usage of the available resources by comparing actual usage to a predetermined threshold value, and taking corrective actions if that threshold is exceeded.

Fairness algorithm for bundle resource utilization

Systems and methods consistent with the present invention provide a better fragment drop heuristic that determines a per-fragment determined 'remainder time' value to trigger potential drops on the whole bundle. A per-bundle drop timeout value is assumed. This value is to be configured based on differential delay considerations of the various links that constitute the bundle. The arrival time of a fragment to a reassembly algorithm triggers a remainder timer. When the reassembly algorithm instance actually processes the fragment, the 'remainder time,' which is difference of a bundle drop timeout and time elapsed on the remainder timer, is used to determine whether the fragment and the other fragments of the packet should be dropped.
