摘要： A method for interconnecting a satellite switch and a virtual switch for communication over a network includes transmitting a multicast packet containing a satellite identifier over the network and receiving a response multicast packet containing the satellite identifier, a satellite index associated with the satellite switch, and a virtual switch index associated with the virtual switch transmitting the response packet. The virtual switch index is mapped into a destination address and the destination address is inserted into a satellite packet. The satellite packet is then transmitted over the network to the virtual switch.

摘要： Techniques for building and managing network policies for accessing resources of a datacenter are described herein. In one embodiment, events are captured within a network element pertaining to certain activities of accessing certain resources of a datacenter, wherein the network element operates as an application service gateway to the datacenter. A new rule/policy is provisioned based on attributes extracted from the captured events, where the attributes includes at least one of user attribute, environment attribute, and a resource attribute. A simulation is performed on the new rule/policy under a real time network traffic condition, generating a simulation result. The new rule/policy is committed if the simulation result satisfies a predetermined condition, wherein the new rule/policy is enforced within the network element to determine whether a particular client is eligible to access a particular resource of the datacenter. Other methods and apparatuses are also described.

摘要： Method and devices are provided for allocating network resources in a flexible manner. In some implementations, a customer's unused resources for a particular type of service are assigned to another type of service. In other implementations, a first customer's unused resources are assigned to a second customer, e.g., in exchange for a relatively lower service charge to the first customer. The unused bandwidth may be assigned on a hierarchical or a non-hierarchical basis. In preferred embodiments, resources are allocated using a token bucket methodology. Preferably, high-priority resources are not compromised by the allocation scheme. The discipline or manner in which resources or bandwidth are shared may be specified in a static fashion or information regarding the state of congestion in the network maybe used to generate a dynamic (time varying) specification.

摘要： In one embodiment, a list of source identifiers is maintained at a virtual switch. These source identifiers are allowed to send packets through the virtual switch to ports in a private virtual local area network (PVLAN). When a packet is received at the virtual switch from a particular source destined for a particular port in the PVLAN, the virtual switch determines whether a particular identifier associated with the particular source matches one of the source identifiers in the list. If that particular source identifier is not on the list, the packet is prevented from being forwarded to the particular port in the PVLAN.

摘要： Application protection architecture with triangulated authorization is described herein. According to one embodiment, a packet of a network transaction is received at a network element from a client system over a first network for accessing a destined server of a datacenter over a second network, where network element operates as a security gateway to the datacenter. In response to the packet, one or more user attributes associated with a user of the client system are obtained from an identity store, where the user attributes include a user identifier that identifies the user and a machine identifier that identifies the client system. Authentication and/or authorization are performed on the packet using the user attributes to determine whether the user of the client system is eligible to access the destined server of the datacenter.

摘要： Layer 4 gateway for a converged datacenter fabric is described herein. According to one embodiment, a packet of a network transaction is received from a client over a first network for accessing a server of a datacenter having a plurality of servers over a second network. One or more network services are performed on the packet including terminating a TCP (transport control protocol) connection associated with the network transaction and generating a data stream. The data stream without TCP information is routed to the server via a converged I/O interface over the second network if the second network is a converged fabric network. The data stream with TCP information is routed via a TCP connection to the server if the second network is an Ethernet. Other methods and apparatuses are also described.
