Embodiment Construction

[0017] It should be appreciated at the outset that while an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of presently known or available techniques. The invention should in no way be limited to the illustrative implementations, drawings, and techniques described below, including the exemplary designs and implementations illustrated and described herein, but within the scope of the appended claims and their equivalents modify the invention within its full scope.

[0018] Faults in bridged networks such as bridged Virtual Local Area Networks (VLANs) may include non-data related faults that may be due to repeated loss or misdirection of frames due to, for example, link or bridge failures. ). Alternatively, the faults may include data-related faults and / or data-induced faults whereby the content of a particular data frame is the cause of the fault. Isolation of data-related faul...

Abstract

A method comprising receiving a data frame, encapsulating the received data frame into a reflected frame message (RFM) encapsulated frame, and if the received data frame causes the RFM encapsulated frame to exceed a maximum service data unit size, either the data frame is truncated or the data frame is split into two smaller frames and those two smaller frames are encapsulated by two separate RFM frames, wherein if a truncation flag is set to be true, the data frame is truncated to be encapsulated in one RFM.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to U.S. Patent Application Serial No. 12 / 415,735, filed March 31, 2009, entitled "Encapsulating Large Ethernet Frames," and to Robert Sultan et al. Priority to U.S. Provisional Patent Application No. 61 / 043,157, entitled "Encapsulating Large Ethernet Frames," filed April 8, 2008, both of which are reproduced as if reproduced in their entirety Incorporated herein by reference. technical field [0003] The present invention relates to the field of telecommunications and, in particular, to encapsulating large Ethernet frames. Background technique [0004] Modern communication and data networks, such as those based on Ethernet bridging technology, include nodes that forward data frames through the network. Various networking standards are used to pass frames over the network. For example, the Institute of Electrical and Electronics Engineers (IEEE) 802.1Qaw standard for Data Dependent an...
