Abstract: Techniques are described for balancing traffic load for networks configured in multi-rooted tree topologies, in the presence of link failures. Maximum flows (through minimum cuts) are calculated for subgraphs that incorporate effective link capacities on links between source and destination nodes. Effective link capacities may be determined that take into account link failures, as well as sharing of current available link capacities by multiple nodes. Traffic is balanced while simultaneously fully utilizing available link capacities, even available link capacities on partially failed links (e.g., partially failed Link Aggregation Groups (LAGs)).

Abstract: In some cases, a network monitoring system may determine an operating or health condition of a node or connection link in a network (e.g., a datacenter network) by preparing an encapsulated data packet according to a tunneling protocol. Depending on a result of routing the encapsulated data packet, the network monitoring system determines whether the node or connection link is functioning normally or is experiencing an issue such as overloading or malfunctioning.

Abstract: Securely storing assets in a cloud computer storage service. Preparation to store assets for a user may comprise determining a location to store the assets, generating a write access signature, and sending the determined location and the signature to the user. A request is received from the user to store the assets. Such a request includes the assets, the location, and the signature. In response to receiving the request, a determination is made regarding the write access signature whether the request should be honored. When the request is honored, the assets are stored in the determined location and the write access signature is invalidated. Upon subsequent user requests to access the assets, short-term read access signatures are generated and provided to the user. The assets are written once per generated write access signature and reads are to be performed close in time to when short-term read access signatures are requested.

Abstract: This application describes routing packets from a source server to a plurality of ports of a switch. The switch is programmed by the control server and is used to direct incoming data packets to one or more ports of the switch in a manner that reduces congestion of incoming data packets to a destination server. Further, the control server queries congestion information from the switch, and then sends congestion notification back to the source server to either increase or decrease the amount of data being sent to the destination server.

Abstract: A virtual data center allocation architecture with bandwidth guarantees that provides for the creation of multiple virtual data centers from a single physical infrastructure. The virtual data center allocation is accomplished in three steps. First, clusters are created from the servers in the physical infrastructure. Second, a bipartite graph is built to map the virtual machines to the servers located in a particular cluster and finally a path is calculated between two virtual machines. The virtual data centers may be dynamically expanded or contracted based on changing bandwidth guarantees.

Abstract: A system, method or computer readable medium to provide efficient congestion notification is described herein. In various embodiments, a packet is received at an intermediate node of one or more data center networks. A current queue length at the intermediate node is determined. A threshold value for the current queue length is tuned by dynamically computing an upper bound and a lower bound based at least in part on the network. The packet is marked to indicate possible congestion in the one or more data center networks when the current queue length exceeds the threshold value. In some embodiments, the packet is marked when it is being de-queued. In a further embodiment, Flexible Initial Packet Size (FIPS) may be utilized to improve the efficiency of the tuning.

Abstract: A load balancer system is described herein which uses one or more switch-based hardware multiplexers, each of which performs a multiplexing function. Each such hardware multiplexer operates based on an instance of mapping information associated with a set of virtual IP (VIP) addresses, corresponding to a complete set of VIP addresses or a portion of the complete set. That is, each hardware multiplexer operates by mapping VIP addresses that correspond to its set of VIP addresses to appropriate direct IP (DIP) addresses. In another implementation, the load balancer system may also use one or more software multiplexers that perform a multiplexing function with respect to the complete set of VIP addresses. A main controller can generate one or more instances of mapping information, and then load the instance(s) of mapping information on the hardware multiplexer(s), and the software multiplexer(s) (if used).

Abstract: Some implementations include routing and/or delivering communications within a network system. In one example, a packet source may be configured to recursively encode a data delivery tree so that any sub-tree formed from the data delivery tree compresses a continuous data block of the data delivery tree.

Abstract: This application describes a system and method for auto configuring data center networks. The networks include a plurality of electronic devices that may include switches, servers, routers, or any other device that may be used in a data center network. Graph theory is applied to the arrangement of the network devices to determine if the intended design of the data network matches the actual implementation of the network. This may be achieved by resolving the blueprint graph with the physical graph to determine if they are isomorphic. Also, the isomorphic techniques may be used to detect miswirings in the network that do not cause a node degree change for any of the network components.
