Transport Optional Upgrade Release Transition Release Notes Announcement Table 2 Transport Enhancements Transition Patch PHNE_35351 and PHNE_35765 PHNE_35765 HP-UX Version Transport Enhancement • NOSYNC Support • Forward-Retransmission Timeout (F-RTO) • New Parameter for the route Command • Congestion Window Validation • Internal TCP and UDP Enhancements • Dynamic keying support for MIPv6 A.02.01 (or later) with IPSec A.02.
Transport Optional Upgrade Release Transition Release Notes Announcement The transition patch PHNE_35351 (for HP-UX 11i v1) implements the MLD protocol specified in RFC 2710. MLD is a protocol used by IPv6 routers to discover the presence of multicast listeners (that is, nodes wishing to receive multicast packets) on its directly attached links. In addition, it is used to discover the specific multicast addresses that are of interest to the neighboring nodes.
Transport Optional Upgrade Release Transition Release Notes Announcement In conformance with RFC 2893 (which obsoletes RFC 1933) configured tunnels are pseudo-interfaces with associated addresses. Previously, when conforming to RFC 1933, tunnels were implemented using special routing entries. The RFC 1933 implementation did not allow addresses to be associated with tunnels and hence, routing protocol daemons were not able to process tunnel information.
Transport Optional Upgrade Release Transition Release Notes Announcement Automatic Tunneling using IPv4-Compatible Addresses is Obsoleted This feature was introduced in TOUR 2.0. Automatic Tunneling using the special IPv6 address type known as "IPv4-compatible address" is no longer supported. The IETF has deprecated this mechanism in favor of the generic automatic tunneling mechanism known as "6to4." Optimized TCP Retransmit Algorithm This feature was introduced in TOUR 2.2.
Transport Optional Upgrade Release Transition Release Notes Announcement The ndd parameter ip_strong_es_model determines if the per-interface default gateway feature is enabled in addition to the strong end-system (SES) model. When the strong end-system model is enabled, packet source addresses (and therefore interfaces on a multihomed host) affect selection of a gateway for outbound packets. Previously, ip_strong_es_model supported two values 0 and 1.
Transport Optional Upgrade Release Transition Release Notes Announcement Forward-Retransmission Timeout (F-RTO) This feature was introduced in TOUR 3.0. When a retransmission timeout occurs, the last window of data is retransmitted. Spurious retransmission timeouts occur, especially due to mobile network devices switching between access points. In such cases, the unnecessary retransmission of the last window of data degrades TCP performance.
Transport Optional Upgrade Release Transition Release Notes Announcement route inet6 [-f] [-n] delete [net|host] v6destination [ / prefix] v6gateway [count] [source v6src] The enhanced route command provides users with greater control over their network packet flow. It greatly enhances the viability of the Strong End System (Strong ES) model of routing packets. Congestion Window Validation This feature was introduced in TOUR 3.0.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the STREAMS Transition Patch Features and Enhancements in the STREAMS Transition Patch The STREAMS transition patch contains features and enhancements for HP-UX STREAMS on HP-UX 11i v1 and HP-UX 11i v2 September 2004. Table 3 Transition Patch PHNE_35453 PHNE_34788 STREAMS Enhancement Transport Enhancement HP-UX STREAMS NOSYNC Enhancement HP-UX Version TOUR Version 11i v1 3.0 11i v2 September 2004 3.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle Features and Enhancements in the IPv6NCF11i Bundle The IPv6NCF11i enhancement bundle for HP-UX 11i v1 enables IPv6 and contains the following features and enhancements: • Point-to-Point Protocol (PPP) Enhancements (PPPv6 and PPPoE) • Router Advertisement Daemon • HP-UX Mobile IPv6 A.01.00.02.02 NOTE The features and enhancements in this bundle apply to HP-UX 11i v1 only.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle The key feature of PPPv6 is conformance to RFC 2472: RFC 2472, "IP Version 6 over PPP," defines how to transmit IPv6 packets over PPP links. It also describes how to form IPv6 link-local addresses on PPP links and to negotiate the type compression protocol to be used for compressing or decompressing IPv6 headers transmitted over serial lines.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle Table 4 Category IP Options Command-Line Options (Continued) Option Description ipv6 local-ifid, remote-ifid Specify two 64-bit IPv6 interface identifiers separated by a comma, the interface identifier of this machine, and the expected interface identifier of the remote machine, after IPv6. Both the interface identifiers are optional.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle connectivity-using a single, fixed IPv6 address for extended periods of time. Without Mobile IPv6, Mobile Nodes cannot use a single, fixed IPv6 address while they roam.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle Address identifying its current location. The Home Agent intercepts data packets sent to the Mobile Node's Home Address and transparently routes them to the Mobile Node's current Care-of Address on the foreign network. Corespondent Node Correspondent Nodes are any IPv6 node communicating or corresponding with a Mobile Node.
Transport Optional Upgrade Release Transition Release Notes Features and Enhancements in the IPv6NCF11i Bundle Prefix Discovery Prefix Discovery allows a Mobile Node to get network prefix information about its Home Network and to configure its Home Address if needed. The Home Agent monitors prefix information from Router Advertisement messages on the Home Network. The Mobile Node can request prefix information by sending a Mobile Prefix Solicitation message to the Home Agent.
