DCCP Well Known ports SHOULD NOT be used without IANA registration. The registration procedure is defined in [RFC4340], Section 19.9. the Registered Ports: are those from 1024 through 49151. DCCP Registered ports SHOULD NOT be used without IANA registration. The registration procedure is defined in [RFC4340], Section 19.9. the Dynamic and/or Private Ports: are those from 49152 through 65535 PLEASE NOTE THE FOLLOWING: 1. UNASSIGNED PORT NUMBERS SHOULD NOT BE USED. THE IANA WILL ASSIGN THE NUMBER FOR THE PORT AFTER YOUR APPLICATION HAS BEEN APPROVED. 2. ASSIGNMENT OF A PORT NUMBER DOES NOT IN ANY WAY IMPLY AN ENDORSEMENT OF AN APPLICATION OR PRODUCT, AND THE FACT THAT NETWORK TRAFFIC IS FLOW- ING TO OR FROM A REGISTERED PORT DOES NOT MEAN THAT IT IS "GOOD" TRAFFIC. FIREWALL AND SYSTEM ADMINISTRATORS SHOULD CHOOSE HOW TO CONFIGURE THEIR SYSTEMS BASED ON THEIR KNOWLEDGE OF THE TRAFFIC IN QUESTION, NOT WHETHER THERE IS A PORT NUMBER REGISTERED OR NOT.

  • 440GX Application Note
    440GX Application Note Overview of TCP/IP Acceleration Hardware January 22, 2008 Introduction Modern interconnect technology offers Gigabit/second (Gb/s) speed that has shifted the bottleneck in communica- tion from the physical connection to the protocol stack. In traditional systems, message processing by the operating system can use a significant number of CPU cycles. The TCP/IP Acceleration Hardware (TAH) sub- system of the 440GX offloads the checksum and segmentation aspects of protocol processing from the operating system, leaving the CPU free to dedicate more cycles to the application. This application note describes the fea- tures and benefits of TAH and its implementation in the 440GX. For additional information on the 440GX, please refer to http://www.amcc.com. TCP/IP Acceleration Hardware In the 440GX, TAH provides hardware acceleration functions for the two 10/100/gigabit Ethernet Media Access Controllers (EMACs) to improve bandwidth and lower CPU utilization. TAH provides checksum verification for TCP/ UDP/IP headers in the receive path, checksum generation for TCP/UDP/IP headers in the transmit path, and TCP segmentation support in the transmit path. TAH provides support for standard and jumbo packets. No acceleration functions are available for the two 10/100 EMACs. For receive packets, setting the Checksum Verification on Receive (CVR) bit in the accelerate mode register, TAHx_MR, enables hardware checksum verification for all incoming packets for a given EMAC/TAH. For transmitted packets, hardware generated checksums and/or packet segmentation is done on a per-packet basis. This is accomplished by setting the proper bits in the descriptor control/status field of the buffer descriptor.
