Described herein are systems, methods, and software to manage the compression of route tables for communication between networking elements. In one implementation, a network device identifies network keys for a route table by replacing attributes in the tables with values. The network device further generates a compressed route table using the route keys and associating each of the route keys with one or more additional attributes. The network device also generates a dictionary to associate each of the values for the route keys to a corresponding attribute of the attributes.

A system is described whereby a cloud router may allow routing as a service in a cloud-like manner. In an example, an apparatus may include a processor and a memory coupled with the processor that effectuates operations. The operations may include receiving first routing information associated with a first customer edge device; adding the first routing information to network routing information of the apparatus, wherein the network routing information comprises a network routing table with routes for a plurality of networks; and propagating the network routing information to a software defined network (SDN) controller, wherein, based on the network routing information, the SDN controller sends a forwarding information base (FIB) to a provider edge device connected with the first customer edge device.

Systems and methods for InfiniBand fabric optimizations to minimize SA access and startup failover times. A system can comprise one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, a plurality of hosts, and a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters. The subnet manager can be configured to determine that the plurality of hosts and the plurality of switches support a same set of capabilities. On such determination, the subnet manager can configure an SMA flag, the flag indicating that a condition can be set for each of the host channel adapter ports.

A route sending method and a device are provided. The method includes: A second network device receives a first route sent by a first network device, where the first route includes an IP address of a source network device and first identification information identifying that an IP address of the first network device belongs to a first type, and the first network device is a next-hop network device of the source network device. The second network device sends the first route, where the first route is a route determined by the second network device based on a first route group, and the first route group is determined based on the IP address of the source network device and the first type, so that routes having the same IP address of the source network device but different types of next-hop addresses can be allocated to different route groups.

A computing device may perform a method that includes graphically presenting a plurality of virtual routing and forwarding (VRF) elements which represent a plurality of stored VRF profiles, with each VRF element presenting profile data from one of the plurality of stored VRF profiles. The method may further include receiving input selecting a VRF element which represents and presents profile data from a selected stored VRF profile and receiving input modifying the profile data presented by the selected VRF element. A VRF profile may be generated, for a networking device of a networking infrastructure, based on the selected stored VRF profile and the input modifying the profile data presented by the selected VRF element. Thereafter, a VRF element may be graphically presented which represents and presents profile data from the generated VRF profile for the networking device.

Embodiments described herein generally involve identifying workloads in a multi-site networking environment. Embodiments include determining that a given network is stretched across a first network segment at a first site and a second network segment at a second site. Embodiments include creating a stretched administrative domain for the given network and mapping an address of the given network to the stretched administrative domain in a lookup table for an administrative domain associated with the first network segment. Embodiments include receiving a flow record from an observation point in the first network segment, the flow record having a source IP address associated with the second network segment and a destination IP address associated with the first network segment. Embodiments include identifying a source workload and destination workload of the flow record using the lookup table and a workload identification table that maps combinations of IP addresses and administrative domains to workloads.
