- The TCP binding of SOME/IP is heavily based on the UDP binding. In contrast to the UDP binding, the TCP binding allows much bigger SOME/IP messages and uses the robustness features of TCP (coping with loss, reorder, duplication, etc.).
SOME / IP的TCP綁定很大程度上基于UDP綁定。 與UDP綁定相比，TCP綁定允許更大的SOME / IP消息并使用TCP的魯棒性（應對丟失，重新排序，復制等）。 - Every SOME/IP payload shall have its own SOME/IP header.
每個SOME / IP payload都應具有自己的SOME / IP hearder。 - In order to lower latency and reaction time, Nagle’s algorithm shall be turned off (TCP_NODELAY).
為了降低延遲和反應時間，應關閉Nagle算法（TCP_NODELAY）。 - When the TCP connection is lost, outstanding requests shall be handled as timeouts. Since TCP handles reliability, additional means of reliability are not needed.
當TCP連接丟失時，未完成的請求應作為超時處理。 由于TCP的可靠性，因此不需要額外的可靠性手段。 - The client and server shall use a single TCP connection for all methods, events, and notifications of a service instance. When having more than one instance of a service a TCP connection per services instance is needed.
客戶端和服務端應對服務實例的所有method，event和notification使用一個TCP連接。 當具有多個服務實例時，則每個服務實例需要一個TCP連接。 - The TCP connection shall be used for as many services as possible to minimize the number of TCP connections between the client and the server (basically only one connection per TCP port of server).
TCP連接應該用于盡可能多的服務，以最小化客戶端和服務端之間的TCP連接數（基本上每個服務端的TCP端口只有一個連接）。 - The TCP connection shall be opened by the client, when the first method call shall be transport or the client tries to receive the first notifications.
當發送第一個method調用或者客戶端打算接收第一個notification，客戶端應該負責打開TCP連接。 - The client is responsible for reestablishing the TCP connection whenever it fails.
客戶端負責在失敗時重新建立TCP連接。 - The TCP connection shall be closed by the client, when the TCP connection is not required anymore.
當不再需要TCP連接時，客戶端應關閉TCP連接。 - The TCP connection shall be closed by the client, when all Services using the TCP connections are not available anymore (stopped or timed out).
當使用TCP連接的所有服務不再可用（停止或超時）時，客戶端應關閉TCP連接。 - The server shall not stop the TCP connection when stopping all services the TCP connection was used for but give the client enough time to process the control data to shutdown the TCP connection itself.
當服務器停止使用某TCP連接的所有服務時，服務器不應停止該TCP連接，但是給客戶端足夠的時間來處理控制數據以關閉TCP連接。 - Rational合理性:
When the server closes the TCP connection before the client recognized that the TCP is not needed anymore, the client will try to reestablish the TCP connection.
當服務器關閉TCP連接而客戶端并不清楚不需要該TCP了，客戶端將嘗試重新建立TCP連接。
