Abstract: Techniques are provided for sending from a client in a first network device a first session-initiate message to a second network device that is configured to provide network layer, data link layer, or associated convergence layer based service connection information in order for the second network device to accept or reject a network layer, data link layer, or associated convergence layer based service connection with the first network device. The first session-initiate message is based on a messaging and presence protocol. A session-accept message is received at the client in the first network device that is configured to accept the service connection and provide a network layer, data link layer, or associated convergence layer based service connection information in order for the first network device to establish the service connection with the second network device. The session-accept message is based on the messaging and presence protocol. In response to receiving the session-accept message, the service connection is established.

Abstract: Techniques are disclosed for zoning information to be shared with an NPIV proxy device or an NPV device such as a blade switch in a blade chassis. Doing so allows the NPV device to enforce zoning locally for the attached server blades and virtualized systems. The NPV device may learn zoning rules using Fiber Channel name server queries and registered state change notifications. Additionally, the NPV device may snoop name server queries to retrieve zoning information (or state change messages) without using the zoning change protocols and without consuming a Fiber Channel domain from the Fiber Channel fabric.

Abstract: In an example embodiment, a new qualifier is added to members in a Fiber Channel zone to specify whether each member is a target or initiator and in another embodiment a time-range attribute is added to a zone in the zoneset. When the zoneset is applied the number of ACL entries that must be programmed is reduced from k×(k−1) entries to 2(k−1) entries for a zone with k members where k−1 members are of one type (e.g. initiators) and one of the members is of a different type (e.g., a tape device). The time-range attribute is enforced by zone server software and enhances security by, for example, limiting access to sensitive data to specified times. In another embodiment, an incremental zoneset activation protocol is implemented where a hash of a zoneset is created by a switch updating the zoneset and the hash and ID of the switch updating the zoneset are sent to all other switches in the fabric when the zoneset is propagated. The hash and switch ID are stored in persistent storage at all switches in the fabric. When a target zoneset is updated by a source switch only the incremental change is propagated to other switches in the fabric along with the hash and switch ID of the target zoneset. Each switch checks a received hash and switch ID against its stored hash and switch ID to assure that the stored local zoneset is the same as the target zoneset before applying the incremental change.

Abstract: Techniques are provided herein for a device in a network to receive information configured to indicate a control plane traffic load level for one or more server devices that are configured to manage traffic for messaging and presence clients communicating via a messaging and presence protocol. The control plane traffic is associated with the messaging and presence protocol. A determination is made as to when the control plane traffic load level has become unbalanced among the two or more server devices and in response to determining that the control plane traffic load level has become unbalanced, sending a transfer message to one or more clients comprising information configured to initiate migration of one or more clients from a server device that is relatively overloaded to a server device that is relatively underloaded in order to balance the control plane traffic load level among the two or more server devices.
