Gorry, I have been intending to submit some text on asymmetric behaviour in Docsis/HFC networks. Hope I can send it out by next Monday(9/3). Best Regards, Jeff Mandin Software System Architect Texas Instruments - Cable Broadband Communications email: jeff.mandin@ti.com -----Original Message----- From: Gorry Fairhurst [mailto:gorry@erg.abdn.ac.uk] Sent: Tue, August 28, 2001 5:11 PM To: pilc@grc.nasa.gov Subject: PILC ASYM: Wording of PEP comparison. I am editing what we hope to be the last rev of draft-ietf-pilc-asym-05.txt prior to a PILC working group last call. The new text of one section attempts to clarify the realtionship of the ASYM draft to the PEP RFC previosuly issued. Although there is broad consensus on the roles of these two documents, the previous wording in the asym draft received some criticsm. Gorry Fairhurst The replacement text below is offered for comment: ------ [RFC3135] describes a class of network device that provides more than forwarding of packets, and which is known as a Protocol Enhancing Proxy (PEP). A large spectrum of PEP devices exist, ranging from simple devices (e.g. ACK filtering) to more sophisticated devices (e.g. that split a TCP connection into two separate parts). The techniques described in section 6 of this document belong to the simpler type, and do not inspect/modify any TCP or UDP payload data. They also do not modify port numbers or link addresses. Many of the risks associated with more complex PEPs do not exist for these schemes. Further information about the operation and the risks associated with using PEPs are described in [RFC3135]. ----- please tsend comments to: gorry@erg.abdn.ac.uk pilc@grc.nasa.gov
