US Patent:

20070274341, Nov 29, 2007

Filed:

May 26, 2006

Appl. No.:

11/442246

Inventors:

Ralph T. Rodriguez - Santa Rosa CA, US

International Classification:

H04J 3/24

US Classification:

370473

Abstract:

A method and system are provided for managing transfer of software images to ONTs over a PON network. The method includes dividing a software image into multiple segments, where each segment is divided into sections. The sections of each segment include at least one unacknowledged section and at least one acknowledged section. The method further includes downloading, over a common broadcast channel to a group of ONTs, the unacknowledged sections of a first segment. The unacknowledged sections are downloaded successively in an unacknowledged manner. The method further includes downloading, over unicast channel to corresponding ONTs within a group of ONTs, the acknowledged section of the first segment. Each of the ONTs in the group of ONTs returns of an acknowledgement or a non-acknowledgement in response to the acknowledged section downloaded from the OLT. The acknowledged or unacknowledged reply message is returned depending upon whether the corresponding ONT is properly received and recorded each section within a corresponding segment.

US Classification:

398 58, 398 63

Abstract:

A Session Initiation Protocol (SIP) network can malfunction or be incorrectly provisioned in such a way that an Optical Network Terminal (ONT) cannot perform SIP operations and complete SIP voice path calls between the ONT voice port and the SIP network. Accordingly, a technique for validating SIP operations is provided which (i) verifies locally stored SIP operation parameters are currently valid, (ii) initiates an SIP session with a known SIP validation endpoint in an event the locally stored SIP operation parameters are verified to be currently valid, and (iii) reports results of the verifying of the locally stored SIP operation parameters or the initiating of the SIP session. By validating SIP operation parameters, the ONT maintains its state of readiness to support SIP sessions, such as in-coming or outgoing normal or emergency 9-1-1 voice calls.

Abstract:

In various example embodiments, a system, method and apparatus are provided for scalable protocol snooping in a PON. In an example embodiment, a method is provided. The method may include receiving a control packet on a network. The method may further include snooping the control packet. The method may also include duplicating the control packet to produce a duplicate control packet. Additionally, the method may include transmitting the control packet and a duplicate control packet to an external network. Moreover, the method may include processing the control packet. In another example embodiment, a method is presented. The method may include receiving a control packet. The method may also include receiving a duplicate control packet on a dedicated port. The method may further include snooping the control packet and the duplicate control packet. Also, the method may include passing the control packet on to an external network. Furthermore, the method may include processing the duplicate control packet.
