Abstract: A non-transitory processor-readable medium storing code representing instructions to be executed by a processor can cause the processor to receive an indication to load balance a group of sessions associated with a network node and a switch across a group of links between a gateway device and the switch at a first time. The code causes the processor to calculate at a second time, a load based on the group of sessions and associated with a first set of links in an active configuration before the first time. The code causes the processor to send a signal to cause a set of sessions from the group of sessions to re-establish themselves at a third time based on a threshold value calculated based on the load such that the set of sessions are load balanced across a second set of links in the active configuration at the third time.

Abstract: BGP can advertise multiple routes for same prefix via BGP add path (RFC 7911). BGP attempts to pack prefixes with same path attributes into the same BGP update message. Protocol nexthop is one of the path attributes. Since these BGP add paths routes usually have different protocol nexthops, different routes for a single prefix could end up being spread out when being advertised. That may, in turn, result in additional calls to download routes to FIB, advertisement to peers and multiple runs of multipath calculation for the same prefix when multipath is configured. To help avoid this situation, when BGP advertises add-path routes, BGP can send the multiple paths for the same prefix in the adjacent update messages. BGP can use extended Network Layer Reachability Information (NLRI) field to carry nexthop along with its associated prefix in BGP update message to send plain IPv4 unicast routes.

Various other apparatuses, systems, and methods are also disclosed.

Abstract: The techniques describe directly forwarding a packet from an ingress packet forwarding engine to a particular destination packet forwarding engine (PFE) when internal packet load balancing may otherwise result in an increased number of fabric hops. For example, a source PFE may receive incoming packets destined for a router reachable only by a particular destination PFE (e.g., egress PFE). Rather than load balancing the incoming packets to a destination PFE that is likely to be a non-egress PFE, a source PFE obtains fabric path information associated with the egress PFE from a destination PFE such that source PFE may forward incoming packets directly to the egress PFE.

Abstract: A network device may generate a route advertisement that includes a media access control (MAC) address. The MAC address may correspond to a data link established between the network device and a customer edge (CE) device. The network device and the CE device may be associated with an Ethernet virtual private network (EVPN) that includes other network devices that are remote from the CE device. The network device may cause the route advertisement to be outputted over the EVPN. The route advertisement may permit the other network devices to learn that the data link is directly reachable via the MAC address, and may permit the other network devices, when configured as maintenance endpoints (MEPs), to directly address performance monitoring-related unicast packets, intended for the data link, using the MAC address, such that flooding of the performance monitoring-related unicast packets is avoided.

The dispatch module initiates a clock signal at the second processing module only if the indication of the workload at the first processing module satisfies a criterion. The dispatch module sends a data unit to the second processing module for processing only if the indication of the workload at the first processing module satisfies a criterion.

Abstract: The problem of routing micro-loops in networks having a CLOS topology, such as data center CLOS networks employing the exterior border gateway protocol (eBGP) for example, is solved by: (a) receiving, on an interface of one of the nodes, a datagram, the datagram including destination information; (b) determining a next hop and an egress interface using (1) an identifier of the interface on which the datagram was received, (2) the destination information of the received datagram, and (3) stored forwarding information such that a routing micro-loop is avoided without discarding the datagram; and (c) forwarding the datagram via the egress interface.

Abstract: Techniques are described for performing session identifier (“SID”) based two-way active measurement protocol (TWAMP) data session provisioning between two endpoints in a computer network. According to the techniques, a SID assigned to each data session is used to uniquely identify the data session, instead of a source and destination address/port pairs. A TWAMP server may generate a unique number as a SID of a data session during negotiation of the data session. The disclosed techniques include extending TWAMP control messaging to include a communication mode for the SID-based TWAMP data session provisioning. The disclosed techniques further include extending TWAMP data messaging to include the SID of the data session in each test packet for the data session. In this way, a TWAMP session sender and a TWAMP session reflector may associate received test packets with a certain data session based on the SID included in the received test packets.
