    摘要： A network system that includes a first set of network hosts in a first domain and a second set of network hosts in a second domain. Within each of the domains, the system includes several edge switching elements (SEs) that each couple to the network hosts and forward network data to and from the set of network hosts. Within the first domain, the system includes (i) an interior SE that couples to a particular edge SE in order to receive network data for forwarding from the edge SE when the edge SE does not recognize a destination location of the network data and (ii) an interconnection SE that couples to the interior SE, the edge SE, and the second domain through an external network. When the edge SE receives network data with a destination address in the second domain, it forwards the network data directly to the interconnection SE.

    摘要： Systems and methods for managing a network are described. A view of current state of the network is maintained where the current state of the network characterizes network topology and network constituents, including network entities and network elements residing in or on the network. Events are announced that correspond to changes in the state of the network and one or more network elements can be configured accordingly. Methods for managing network traffic are described that ensure forwarding and other actions taken by network elements implement globally declared network policy and refer to high-level names, independently of network topology and the location of network constituents. Methods for discovering network constituents are described, whereby are automatically configured. Routing may be performed using ACL and packets can be intercepted to permit host to continue in sleep mode. The methods are applicable to virtual environments.

    摘要： Some embodiments provide a system that detects whether a flow is an elephant flow; and if so, the system treats it differently than a mouse flow. The system of some embodiment detect elephants based on one or more of the following: statistics associated with a flow, packet segment size, and invoked system calls. Also, some embodiments use one or more various methods to handle elephant flows. Examples of such methods include marking each packet belonging to an elephant with a particular marking, breaking the elephants into mice, reporting the elephant to a network controller, and selectively choosing a route for each packet belonging to the elephant.
